what is the equivalent for assertDatabaseHas in Django

Question

Coming from Laravel background learning Django. Forgive me if my question is naive.

response = self.client.delete(reverse('details'), kwargs={'pk':pk}, format="json")

self.assertEqual(response.status_code, status.HTTP_204_NO_CONTENT)

The above test passes, and I would like to go a little further and try to check if the database actually has this item, of course I can query the db and try to match the count. But in Laravel I have used these methods to check for the existence/nonexistence of records.

assertDatabaseHas('users', ['id' => 10]); //asserts true if record is present in users table.

assertDatabaseMissing('users', ['id' => 10]); // asserts true if record is not present in users table

Is there something similar present in Django?

Answer 1

There's no specific assertion for this.

You could perhaps use a general assertTrue along with the exists filter:

self.assertTrue(User.objects.filter(id=10).exists())

(Normally you'd use get() with an id query, but that doesn't allow exists() and you'd have to catch the DoesNotExist exception if it's not found.)
