Django survey

A django survey app, based on and compatible with "django-survey". You will be able to migrate your data from an ancient version of django-survey, but it has been ported to python 3 and you can export results as CSV or PDF using your native language.

If you want the latest version still compatible with python 2.7 you need a version < 1.3.0.

• Chinese thanks to 朱聖黎 (Zhu Sheng Li), John Lyu and Anton Melser (with help from 宋璐)
• French thanks to Pierre Sassoulas and Anton Melser
• Japanese thanks to Nobukuni Suzue
• Spanish thanks to Javier Ordóñez, Pierre Sassoulas and Anton Melser
• Russian thanks to Vlad M. and Anton Melser
• German thanks to Georg Elsas

Getting started

Add django-survey-and-report to your requirements and get it with pip.

echo 'django-survey-and-report' > requirements.txt
pip install -r requirements.txt

Add bootstrapform and survey in the INSTALLED_APPS in your settings :

INSTALLED_APPS = [
	# Your own installed apps here
]

from pathlib import Path

CSV_DIRECTORY = Path("csv") # Define the directory where csv are exported
TEX_DIRECTORY = Path("tex") # Define the directory where tex files and pdf are exported

INSTALLED_APPS += [
	'bootstrapform',
	'survey'
]

Add an URL entry to your project’s urls.py, for example:

from django.conf import settings
from django.conf.urls import include, url

urlpatterns = [
    # Your own url pattern here
]

if 'survey' in settings.INSTALLED_APPS:
    urlpatterns += [
        url(r'^survey/', include('survey.urls'))
    ]

Note: you can use whatever you wish as the URL prefix.

You can also change some options:

# Permit to open the csv in excel without problem with separator
# Using this trick : https://superuser.com/a/686415/567417
EXCEL_COMPATIBLE_CSV = True

# The separator for questions (Default to ",")
CHOICES_SEPARATOR = "|"

# What is shown in export when the user do not answer (Default to "Left blank")
USER_DID_NOT_ANSWER = "NAA"

# Path to the Tex configuration file (default to an internal file that should be sufficient)
from pathlib import Path
TEX_CONFIGURATION_FILE = Path("tex", "tex.conf")

# Default color for exported pdf pie (default to "red!50")
SURVEY_DEFAULT_PIE_COLOR = "blue!50"

To uninstall django-survey-and-report, simply comment out or remove the 'survey' line in your INSTALLED_APPS.

If you want to use the pdf rendering you need to install xelatex. If you're using the Sankey's diagram generation you will also have to install python-tk (for python 2.7) or python3-tk (for python 3.x).

Making a survey

Using the admin interface you can create surveys, add questions, give questions categories, and mark them as required or not. You can define choices for answers using comma separated words.

The front-end survey view then automatically populates based on the questions that have been defined and published in the admin interface. We use bootstrap3 to render them.

Submitted responses can be viewed via the admin backend, in an exported csv or in a pdf generated with latex.

Generating a pdf report from the survey's result

There is a default configuration for PDF generation, but you might want to change TEX_CONFIGURATION_FILE for better results (in particular for language other than english).

You can manage the way the report is created in a yaml file, globally, survey by survey, or question by question. In order to render pdf you will need to install xelatex. You will also need python3-tk for sankey's diagram.

The results are generated for the server only when needed, but you can force it as a developer with:

python manage.py exportresult -h

Following is an example of a configuration file. you can generate one with:

python manage.py generatetexconf -h

Basic example

generic:
  document_option: 11pt
'Test survëy':
  document_class: report
  questions:
    'Lorem ipsum dolor sit amët, <strong> consectetur </strong> adipiscing elit.':
      chart:
        type: polar
        text: pin
    'Dolor sit amët, consectetur<strong>  adipiscing</strong>  elit.':
      chart:
        type: cloud
        text: inside

The pdf is then generated using the very good pgf-pie library.

Sankey diagram

If you installed python3-tk, you can also show the relation between two questions using a sankey diagram :

'Lorem ipsum dolor sit amët, <strong> consectetur </strong> adipiscing elit.':
  chart:
    type: sankey
    question: 'Dolor sit amët, consectetur<strong>  adipiscing</strong>  elit.'

You get this as a result:

Advanced example

You can also limit the answers shown by cardinality, filter them, group them together and choose the color for each answer or group of answers.

If you use this configuration for the previous question:

'Test survëy':
  'Dolor sit amët, consectetur<strong>  adipiscing</strong>  elit.':
    multiple_charts:
      'Sub Sub Section with radius=3':
        color:
          Yës: blue!50
          No: red!50
          Whatever: red!50!blue!50
        radius: 3
      'Sub Sub Section with text=pin':
        group_together:
          Nah:
            - No
            - Whatever
          K.:
            - Yës
        color:
          Nah: blue!33!red!66
          K.: blue!50
        text: pin
    chart:
      radius: 1
      type: cloud
      text: inside

You get this as a result:

Implementing a custom treatment

If you want to make your own treatment you can use your own class, for example.

Configuration:

'Test survëy':
  questions:
    'Ipsum dolor sit amët, <strong> consectetur </strong>  adipiscing elit.':
      chart:
        type: survey.tests.exporter.tex.CustomQuestion2TexChild

Code in survey.tests.exporter.tex.CustomQuestion2TexChild:

from survey.exporter.tex.question2tex_chart import Question2TexChart


class CustomQuestion2TexChild(Question2TexChart):

    def get_results(self):
        self.type = "polar"
        return """        2/There were no answer at all,
        3/But we have a custom treatment to show some,
        2/You can make minor changes too !"""

Result:

For a full example of a configuration file look at example_conf.yaml in doc, you can also generate your configuration file with python manage.py generatetexconf -h, it will create the default skeleton for every survey and question.

To guide you during the python development, you can read:

• The default reporter for PieChart in Question2TexChart : https://github.com/Pierre-Sassoulas/django-survey/blob/master/survey/exporter/tex/question2tex_chart.py#L13
• The Sankey reporter in Question3TexSankey : https://github.com/Pierre-Sassoulas/django-survey/blob/master/survey/exporter/tex/question2tex_sankey.py#L15
• The Raw reporter in Question2TexRax : https://github.com/Pierre-Sassoulas/django-survey/blob/master/survey/exporter/tex/question2tex_raw.py.

Do not hesitate to make a pull request with your new exporter if it can be of interest for others I'll integrate it.

Contributing as a developer

Development environment

This is the typical command you should do to get started:

python -m venv venv/ # Create virtualenv
source venv/bin/activate # Activate virtualenv
pip install -e ".[dev]" # Install dev requirements
pre-commit install # Install pre-commit hook framework
python manage.py migrate # Create database
python manage.py loaddata survey/tests/testdump.json # Load test data
python manage.py createsuperuser
python manage.py runserver # Launch server

Please note that pre-commit will permit to fix a lot of linting error automatically and is not required but highly recommended.

Committing code

Launching tests

python manage.py test survey

Adding test data

If you want to dump a test database after adding data to it, this is the command to have a minimal diff :

python manage.py dumpdata --format json -e contenttypes -e admin -e auth.Permission
-e sessions.session -e sites.site --natural-foreign --indent 1
-o survey/tests/testdump.json

Launching coverage

coverage run --source=survey --omit=survey/migrations/* ./manage.py test
coverage html
xdg-open htmlcov/index.html

Applying Lint

We're using pre-commit, it should take care of linting during commit.

Translating the project

Django survey's is available in multiple language. Your contribution would be very appreciated if you know a language that is not yet available.

As a developer

If your language do not exists add it in the LANGUAGE variable in the settings, like here. Do not forget to credit yourself like in the header seen here

Then you can translate with :

python manage.py makemessages
# python manage.py createsuperuser ? (You need to login for rosetta)
python manage.py runserver
# Access http://localhost:8000/admin to login
# Then go to http://localhost:8000/rosetta to translate
python manage.py makemessages --no-obsolete --no-wrap
git add survey/locale/
...

If your language is not yet available in rosetta, this stack overflow question should work even for language not handled by django.

As a translator

If you're not a developer, open an issue on github and ask for a .po file in your language. I will generate it for you, so you can edit it with an online editor. I will then create the .po and commit them, so you can edit them with your github account or integrate it myself if you do not have one. You will be credited here.
