django-legal

This Django app adds support for versioned terms of service.

Installation

1. Install with pip:

   $ pip install django-legal
   

2. Add legal to your INSTALLED_APPS setting.

3. (Optional) Add a new setting: LEGAL_TOS_NAME = 'terms_of_service'

4. Update urls.py with the following:

   url(r'^legal/', include('legal.urls')),
   

5. Create a new Agreement and AgreementVersion (ideally via data migration):

   # -*- coding: utf-8 -*-
   import os
   from south.v2 import DataMigration
   
   # This should be the same value as LEGAL_TOS_NAME (if you overrode it)
   AGREEMENT_NAME = 'tos'
   
   
   class Migration(DataMigration):
       def forwards(self, orm):
           agreement, created = orm['legal.Agreement'].objects.get_or_create(name=AGREEMENT_NAME)
   
           # This file should live in the same directory as the migration
           f = open('%s/tos_content_2013_08_01.html' % os.path.dirname(__file__), 'r')
           orm['legal.AgreementVersion'].objects.create(agreement=agreement, date='2013-08-01', content=f.read())
   
       def backwards(self, orm):
           agreement = orm['legal.Agreement'].objects.get(name=AGREEMENT_NAME)
           agreement.delete()
   
       models = {
           'legal.agreement': {
               'Meta': {'object_name': 'Agreement'},
               'id': ('django.db.models.fields.AutoField', [], {'primary_key': 'True'}),
               'name': (
                   'django.db.models.fields.CharField', [], {'unique': 'True', 'max_length': '50', 'db_index': 'True'})
           },
           'legal.agreementversion': {
               'Meta': {'ordering': "['-date']", 'unique_together': "(('agreement', 'date'),)",
                        'object_name': 'AgreementVersion'},
               'agreement': ('django.db.models.fields.related.ForeignKey', [], {'to': "orm['legal.Agreement']"}),
               'content': ('django.db.models.fields.TextField', [], {}),
               'date': ('django.db.models.fields.DateTimeField', [], {}),
               'id': ('django.db.models.fields.AutoField', [], {'primary_key': 'True'})
           }
       }
   
       # Change this to be the name of the app where the migration lives
       complete_apps = ['my-app']
       symmetrical = True
   

Testing This App

A modified manage.py and Django settings file are included to test this app:

$ python manage.py test

Testing Your App

You may find the middleware a bit excessive for your tests as it requires you to create an agreement and version, and accept the agreement on behalf of your tests users. If you want to disable the middleware, add the following to your settings:

if 'test' in sys.argv:
  MIDDLEWARE_CLASSES = list(MIDDLEWARE_CLASSES)
  MIDDLEWARE_CLASSES.remove('legal.middleware.TermsOfServiceAcceptanceMiddleware')
