Customize Django ContentType

Question

I have a model like this:

class BlockedItem(models.Model):
    name = models.CharField(max_length=244)
    content_type = models.ForeignKey(ContentType)
    object_id = models.PositiveIntegerField()
    content_object = generic.GenericForeignKey('content_type', 'object_id')

    def __unicode__(self):
        return self.name

• In django admin, content_type fetch all models. Could I give only wanted models in content_type ?

• In object_id, is there any way to select from a list instead of enter object_id ?

Answer 1

If you want only some models in content_type you can use

limit_choices = models.Q(app_label = 'myapp', model = 'MyModel') | models.Q(app_label = 'myotherapp', model = 'MyModelOtherModel') )
content_type = models.ForeignKey(ContentType, limit_choices_to = limit_choices )
