Question

My goal is to create a form that display multiple checkboxes and allows users to select one or more choices. All those choices need to be translated.

While using non-model driven form and CHOICES it works as expected.

COLOR_CHOICES = (
    (1, _('Red')),
    (2, _('Black')),
)

Since my form is model based instead of MultipleChoiceField I have to use ModelMultipleChoiceField.

colors = forms.ModelMultipleChoiceField(
    queryset=Colors.objects, # <- This needs to exist in the database so can't use CHOICES
    widget=forms.CheckboxSelectMultiple(),
    required=False
)

Since ModelMultipleChoiceField queries the database to get the choices I have to have the data in the database in the first place.

I can think of two solutions to this problems but I am not sure how to make it work (possibly there is a different approach I am not aware of):

1. Create a fixture and translate it (translation is the problem here)

2. Use choices for the queryset in ModelMultipleChoiceField

Answer 1

You should translate Colors model. I send to you an active project that make easy the job: django-modeltranslation

Learn more about this project is in my TODO list.

Also, take a look to Dynamic Translation Apps for Django from muhuk.com blog.
