django-separatedvaluesfield 0.4.0

Installation

Install package from PyPi:

pip install django-separatedvaluesfield

Or download the archive from GitHub and proceed to a manual installation:

curl -L https://github.com/thoas/django-separatedvaluesfield/tarball/master | tar zx
cd thoas-django-separatedvaluesfield
python setup.py install

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,
        token=',',
        choices=(
            ('en', 'English'),
            ('fr', 'French')))

If your choices values are not strings, add the cast option with the type you want to apply on values (defaults to django.utils.six.text_type):

# 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,
        cast=int,
        token=',',
        choices=(
            (1, 'English'),
            (2, 'French')))

If you are running Django <= 1.6, synchronize your database using syncdb:

python manage.py syncdb

If you are running Django >= 1.7, synchronize your database using migrate:

python manage.py migrate

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

>>> from myapp.models import Project
>>> project = Project(name='Project with strings', languages=['fr', 'en'])
>>> project.save() # save 'fr,en' in database for the column "languages"
>>> project.pk
1

>>> project = Project.objects.get(pk=1)
>>> project.languages
['fr', 'en']

# If you added "cast" option to the field to cast to 'int'
>>> project = Project(name='Project with integers', languages=[u'1', u'2'])
>>> project.save() # save '1,2' in database for the column "languages"
>>> project = Project.objects.get(pk=1)
>>> project.languages
[1, 2]
