Installation

  1. Download the package on GitHub or simply install it via PyPi

  2. Add SeparatedValuesField to your Django model

    # models.py
    from django.db import models
    
    from separatedvaluesfield.models import SeparatedValuesField
    
    
    class Project(models.Model):
        name = models.CharField(max_length=150)
        languages = SeparatedValuesField(max_length=150, choices=(('en', 'English'),
                                                                  ('fr', 'French')), token=',')
    
  3. Sync your database using syncdb command from django command line

The SeparatedValuesField behaves like a CharField which separates values with a token (default is ,).

This field is transformed as a MultipleChoiceField when you are creating a forms.ModelForm with your model.

Usage

In [1]: from myapp.models import Project

In [2]: project = Project(name='Foo', languages=['fr', 'en'])

In [3]: project.save() # save 'fr,en' in database for the column "languages"

In [4]: project.pk
1

In [5]: project = Project.objects.get(pk=1)

In [6]: project.languages
['fr', 'en']
