When referencing a non-existing entity instance in fixtures for ForeignKey
relationship no error message is thrown in test runner mode (./manage.py
test). Please note below how in fixtures instance of Parent contains
invalid ID for Child object (2 instead of 1).

This seems to be related to "always opened transaction" natures of tests,
because if I run ./manage.py testserver data.json I actually get an
exception thrown.

Backend is Postgresql 8.3.

Model:
{{{
5 class Parent(models.Model):
6 child = models.ForeignKey('Child')
7
8 class Child(models.Model):
9 name = models.CharField(default='some name', max_length=100)
}}}

Fixture (data.json):
{{{
352 {
353 "pk": 1,
354 "model": "testapp.parent",
355 "fields": {
356 "child": 2
357 }
358 },
359 {
360 "pk": 1,
361 "model": "testapp.child",
362 "fields": {
363 "name": "child"
364 }
365 }
}}}

Test:

7 fixtures = ['data.json']

9 def test_data(self):
10 self.assertEqual(len(models.Parent.objects.all()), 1)
11 self.assertEqual(len(models.Child.objects.all()), 1)
}}}
