The questionnaire app was originally developed by [Seantis](https://github.com/seantis), itself derived from [rmt](https://github.com/rmt). We picked up the project because we had been using it and the Seantis version had entered a steady state of development. There are several feature changes we wanted & decided to head up the maintenance ourselves.
The questionnaire app was originally developed by [Seantis](https://github.com/seantis), itself derived from [rmt](https://github.com/rmt). We picked up the project because we had been using it and the Seantis version had entered a steady state of development. There are several feature changes we wanted and decided to head up the maintenance ourselves.
The old versions are tagged as follows:
* tag 1.0 - state of last commit by the original developer (rmt)
* tag 1.1 - contains merged changes by other forks improving the original
* tag 2.0 - original updated trunk from Seantis version.
* tag 2.5 - contains the original Seantis version & all PRs merged in as of 12/09/15. It's considered to be the backwards compatible version of the repository.

The new version is the current trunk and is dubbed v3.0. v3.0 should be considered a new project & thus will contain backwards incompatible changes. When possible, we'll try and backport fixes to the v2.x branches, but it will not be a priority.

Though this approach certainly works fine it does not give you a good performance. The problem is, if you have hundreds of questions controlled by runinfo tags, that you end up with most CPU cycles spent on calculating the progress bar on each request. It is precisely for that reason that we implemented the QUESTIONNAIRE_PROGRESS setting (you can learn more about that by looking at the example settings.py).
We managed to keep our rendering time low by doing the progress bar using ajax after a page was rendered. It is only a workaround though. Calculating the progress of a run in a huge questionnaire remains a heavy operation, so for really huge questionnaires one might consider removing the progress bar alltogether. There is still some optimization to be had, but it essentially will remain the slowest part of the questionnaire, because at the end of the day interpreting loads of checks is not something you can do in a fast way, unless your name is PyPy and your programmers are insanly talented.

### There are not Enough Tests
There are a couple of tests which do some simple testing, but it's not enough. We failed to add more so far, so we can't shift the blame, but the fact remains still. More tests would mean that more refactoring could be done which would be nice, because there certainly is a need for some refactoring.

### The Admin Interface is not Good Enough
Django admin is a nice feature to have, but we either don't leverage it well enough, or it is not the right tool for the questionnaire. In any case, if you are expecting your customer to work with the questionnaire's structure you might have to write your own admin interface. The current one is not good enough.
