Filter ForeignKey by Boolean value in django

Question

I have these models:

class Client(models.Model):
    is_provider = models.BooleanField()

class Billing(models.Model):
    client = models.ForeignKey(Client)

I want to limit the choices of ForeignKey to show only the clients with is_provider=True. Is there something like:

limit_choices_to = {'is_provider': True}

Or anything I can use to filter the ForeignKey?

Answer 1

Do you have tried the following:

limit_choices_to = {'client__is_provider': True}

Answer 2

Yes, you have the exact syntax already.

client = models.ForeignKey(Client, limit_choices_to = {'is_provider': True})
