Question

Is there a way to specify a Model in Django such that is ensures that pair of fields in unique in the table, in a way similar to the ‘unique=True’ attribute for similar field?

Or do I need to check this constraint in the clean() method?

Answer 1

There is a META option called unique_together. For example:

class MyModel(models.Model):     field1 = models.BlahField()     field2 = models.FooField()     field3 = models.BazField()      class Meta:         unique_together = ('field1', 'field2') 

More info on the Django documentation page.
