my scenario
Ramiro, I CCed you because of this comment: ticket:10405#comment:46
app_a/models.py
{{{#!python
class Model_A(models.Model):
name = models.CharField(...)
}}}
app_b/models.py
{{{#!python
class Model_B(models.Model):
field_a = models.ForeignKey('app_a.Model_A' ...)
}}}
app_b/forms.py
{{{#!python
from app_b.models import Model_B
class FormModel_B(forms.ModelForm):
class Meta:
model = Model_B
}}}
On app_b/tests/test_forms.py I have
{{{#!python
from app_b.forms import FormModel_B
}}}
And it gives me a {{{ValueError}}}
{{{ ValueError: Cannot create form field for 'field_a' yet, because its
related model 'app_a.Model_A' has not been loaded yet }}}
But when I just import Model_A on app_b/models.py file
{{{#!python
from app_a.models import Model_A
class Model_B(models.Model):
field_a = models.ForeignKey('app_a.Model_A' ...)
}}}
my settings.py
{{{#!python
INSTALLED_APPS = (
...
'app_a',
'app_b',
}
}}}
It works.
This is actually code from the project that I created to reproduce the
behavior.

I'm willing to try fix this issue since it's accepted.
Best Regards.
