A Django app for building custom web forms and collecting submissions.
Project description
Django Formulaic
Django Formulaic allows Django Admin users to create custom forms. The generated forms are rendered using an extension of Django's Form class. Form submission data is collected by the app and accessible via its admin interface.
The app was originally developed for internal use. We hope others will find it useful, but it definitely lacks polish at this point in its development.
Implementation
Configuration
# settings.py
INSTALLED_APPS = [
# ...
'django_filters',
'rest_framework',
'formulaic',
'admin_ordering',
# ...
]
# urls.py
urlpatterns = [
# ...
path('formulaic/', include('formulaic.urls')),
path('admin/', admin.site.urls),
]
# settings.py
FORMULAIC_EXPORT_STORAGE_LOCATION = '/data/shared/assets/formulaic_exports'
Example Usage
The CustomForm class extends Django's forms.Form class, so you can expect a lot of the same behavior you see in Django's documentation.
# urls.py
from django.contrib import admin
from django.urls import path, include
from formulaic_demo import views as fd_views
urlpatterns = [
path('form-test/', fd_views.test_formulaic_form),
path(
'form-test/completed/',
fd_views.test_formulaic_form_complete,
name='form-complete'
),
path('formulaic/', include('formulaic.urls')),
path('admin/', admin.site.urls),
]
# formulaic_demo/views.py
from django.shortcuts import redirect, render
from formulaic.forms import CustomForm
from formulaic.models import Form
def test_formulaic_form(request):
formulaic_form = Form.objects.get(slug='robot-form')
if request.method == 'POST':
form = CustomForm(
request.POST,
request=request,
# page-specific name for form. will be stored with each submission in the
# `source` field.
instance_id='form-page-a',
form=formulaic_form
)
if form.is_valid():
formulaic_form.create_submission(
form.cleaned_data,
source=form.instance_id,
metadata={
'extra-data-1': 'some data',
'extra-data-2': 'more data',
}
)
return redirect('form-complete')
elif not form.is_valid():
errors = form.errors
# raise Exception('Not valid {}'.format(form.errors))
return render(request, 'formulaic_demo/formulaic-form.html', {
'form': form
})
else:
form = CustomForm(
request=request,
# page-specific name for form. will be stored with each submission in the
# `source` field.
instance_id='form-page-a',
form=formulaic_form
)
return render(request, 'formulaic_demo/formulaic-form.html', {
'form': form
})
def test_formulaic_form_complete(request):
formulaic_form = Form.objects.get(slug='robot-form')
return render(request, 'formulaic_demo/formulaic-form-complete.html', {
'message': formulaic_form.success_message,
})
