{{{
class Catalog(models.Model):

}}}

Catalog.parent always return null, while Catalog.children.all() works
fine.

Comment:

I tried this and it worked for me:

{{{
In [1]: from test_app.models import Catalog

In [2]: parent = Catalog.objects.create()

In [3]: child = Catalog.objects.create(parent=parent)

In [4]: child.parent
Out[4]: <Catalog: Catalog object (1)>

In [5]: child.refresh_from_db()

In [6]: child.parent
Out[6]: <Catalog: Catalog object (1)>
}}}
