Question

I need my users to be able to state the langue(s) they speak, so naturally I started with:

class Language(models.Model):
    name = models.CharField(max_length=128)

class UserProfile(models.Model):
    languages = models.ManyToManyField("Language", related_name="users")

But then I discovered this:

from django.conf.global_settings import LANGUAGES

Which I’d like to use, if only to keep to the DRY principle. The problem is, I can’t figure out how to allow a user to have multiple languages.

Answer 1

How about…

class LanguageSpoken(models.Model):
     user = models.ForeignKey("UserProfile")
     language = models.CharField(max_length = 2, choices = LANGUAGES)

I’m assuming you don’t need to keep any other data about the language (like the countries it is spoken in), you just want users to list the languages they speak. If you do need to keep other data, you’ll have to use a many-to-many relationship.
