Reusable prompt and user responses data schema for Django

prompt_responses

A flexible prompt and user responses data schema utilizing Django's content types framework.

This app was born during a university research project. The main use case is data collection. It lets you create numerous kinds of "prompts" (questions or tasks) and record user responses. Prompts can be populated with any kind of database object.

This supports these kind of prompts:

• How do you feel today on a 1-5 scale? (Simple likert question)
• How do you like {object} on a 1-10 scale? (Object-based likert question)
• Which word do you associate with {object}? (Object-based open-ended question)
• How related do you think is {object} to these other objects? (Tagging task)

Ratings and tags are simply integer values, their meaning can be defined by your application (e.g. 1 to 5 scales, or -1 = no, +1 = yes, and so on).

Quickstart

Install prompt_responses:

pip install django-prompt-responses

Add it to your INSTALLED_APPS:

INSTALLED_APPS = (
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    ...
    'prompt_responses',
    'sortedm2m',  # for the ability to change the order of Prompts in the Django admin
    ...
)

Create Prompts, e.g. through the integrated admin views.

Deliver a prompt to the user:

prompt = Prompt.objects.get(id=1)
instance = prompt.get_instance()

"""
Use these variables to display the UI:
prompt.type
str(instance)
instance.object
instance.response_objects
"""

Save a user response:

prompt = Prompt.objects.get(id=1)
prompt.create_response(
    user=user,
    prompt_object=instance.object,
    rating=5
)

Analyze data:

prompt = Prompt.objects.get(id=1)
# Mean rating for all responses
rating = prompt.get_mean_rating()
# Mean ratings for all objects
matrix = prompt.get_mean_tag_rating_matrix()
# Mean ratings for one object
ratings = list(prompt.get_mean_tag_ratings(instance.object))

Use the included viewsets in your Django Rest Framework API:

from rest_framework import routers
from prompt_responses.viewsets import PromptViewSet

router = routers.DefaultRouter()
router.register(r'prompts', PromptViewSet)

urlpatterns = [
    url(r'^api/', include(router.urls))
]

This offers api/prompts/, api/prompts/<id>/, api/prompts/<id>/instantiate/, api/prompts/<id>/create-response/ (POST) endpoints.
