Comment:
With the same code piece I just inserted test1 test2 test3 as slug field
values for ParentModel and testc1 testc2 and testc3 for ChildModel and
linked testc2 to testc1 and testc3 to testc2
The bug is not just in the admin, it happens on the interactive
interpreter too. This is the small piece of test code on the interpreter.
>>> from dummy.testapp.models import ChildModel, ParentModel
>>> ChildModel.objects.all()
[<ChildModel: testc1>, <ChildModel: testc2>, <ChildModel: testc3>]
>>> ParentModel.objects.all()
[<ParentModel: test1>, <ParentModel: tes2>, <ParentModel: test3>,
<ParentModel: testc1>, <ParentModel: testc2>, <ParentModel: testc3>]
>>> c2 = ChildModel.objects.get(slug='testc2')
>>> c2.links
<django.db.models.fields.related.ManyRelatedManager object at 0x99c490c>
>>> c2.links.all()
[]
>>> c1 = ChildModel.objects.get(slug='testc1')
>>> c1.links.all()
[<ParentModel: testc2>, <ParentModel: testc3>]
>>> c3 = ChildModel.objects.get(slug='testc3')
>>> c3.links.all()
[]
So I suppose this bug is not just in admin Interface but in the ORM
itself. So I change the component. Can some one help me track this bug and
fix it? As in how to go about? Where to look for the code?
