Question

Here’s a use case:

class Tweet(models.Model):
url_1 = models.CharField(max_length=140)
url_2 = models.CharField(max_length=140)
url_3 = models.CharField(max_length=140)

I’d like the user to specify at least one URL for each Tweet instance.

I know how to enforce this condition in views.py, but I’m wondering if there’s a way to configure a Django model such that the user is required to fill in at least one out of a given set of model fields before an instance can be saved. I think that solution would be cleaner.

Thanks!

Answer 1

It can’t be done at the model level, but it may be possible to add a constraint at the database level that can enforce this.
