Django Model MultipleChoice

From the two, https://pypi.python.org/pypi/django-select-multiple-field/ looks more well rounded and complete. It even has a nice set of unittests.

The problem I found is that it throws a Django 1.10 deprecation warning in the class that implements the model field.

I fixed this and sent a PR. The latest code, until they merge my PR (if they ever decide to hehe) is in my fork of the repo, here: https://github.com/matiasherranz/django-select-multiple-field

Cheers!

In case You are using Postgres consider using ArrayField.

from django.db import models
from django.contrib.postgres.fields import ArrayField

class WhateverModel(models.Model):
    WHATEVER_CHOICE = u'1'
    SAMPLE_CHOICES = (
        (WHATEVER_CHOICE, u'one'),
    )
    choices = ArrayField(
        models.CharField(choices=SAMPLE_CHOICES, max_length=2, blank=True, default=WHATEVER_CHOICE),
    )

You need to think about how you are going to store the data at a database level. This will dictate your solution.

Presumably, you want a single column in a table that is storing multiple values. This will also force you to think about how you will serialize - for example, you can't simply do comma separated if you need to store strings that might contain commas.

However, you are probably best off using a solution like django-multiselectfield

In Your Case, I used ManyToManyField

It Will be something like that:

class MY_CHOICES(models.Model)
    choice = models.CharField(max_length=154, unique=True)

class MODEL(models.Model):
    ...
    ...
    my_field = models.ManyToManyField(MY_CHOICES)

So, now you can select multiple choices
