django-questionnaire-core

A django application which can be used as a base / starting point for questionnaire functionality in your project. It heavily relies on django form fields & widgets and uses PostgreSQL JSON fields to store the results.

Requirements

• Python version 3.6+
• Django version 2.2+
• django-ordered-model
• A PostgreSQL Database

Quick start

1. Add "questionnaire_core" and its dependency to your INSTALLED_APPS setting like this:

   INSTALLED_APPS = [
       ...
       'ordered_model',
       'questionnaire_core',
   ]
   

2. Create a view based on questionnaire_core.views.generic.QuestionnaireFormView; a simple version might look like this:

   from django.http import HttpResponseRedirect
   from django.urls import reverse
   from django.utils.http import urlencode
   
   from questionnaire_core.models import Questionnaire, QuestionnaireResult
   from questionnaire_core.views.generic import QuestionnaireFormView
   
   class BasicQuestionnaireView(QuestionnaireFormView):
       template_name = 'basic_questionnaire.html'
   
       def get_questionnaire(self):
           return Questionnaire.objects.get(pk=self.kwargs.get('pk'))
   
       def get_questionnaire_result_set(self):
           if self.request.GET.get('result_set'):
               return QuestionnaireResult.objects.get(pk=self.request.GET.get('result_set'))
           return QuestionnaireResult(questionnaire=self.get_questionnaire())
   
       def get_success_url(self):
           return reverse('basic_questionnaire', args=(self.kwargs.get('pk'),))
   
       def form_valid(self, form):
           # Add current result set to the url (allows editing of the result)
           redirect = super().form_valid(form)
           url_params = urlencode({'result_set': form.current_result_set.pk})
           return HttpResponseRedirect('{url}?{params}'.format(url=redirect.url, params=url_params))

3. Add the new view to your URLconf:

   path('questionnaire/<int:pk>/', BasicQuestionnaireView.as_view(), name='basic_questionnaire'),
   

4. Run python manage.py migrate to create the questionnaire_core models.

5. Start the development server and visit http://127.0.0.1:8000/admin/ to create a questionnaire (you'll need the Admin app enabled).

6. Visit http://127.0.0.1:8000/questionnaire/1/ to test your first questionnaire.

Development setup

1. Upgrade packaging tools:

   python -m pip install --upgrade pip
   python -m pip install --upgrade setuptools wheel

2. Install Django (the example_app expects django 3.1):

   python -m pip install Django~=3.1.0 django-ordered-model psycopg2

3. Install tox, isort & flake8

   python -m pip install tox isort flake8
