hi,
I have the following models:
class AbstractTaskOrProject(Model)
parent = ForeignKey('AbstractProject')
class Meta:
abstract = True
class AbstractProject(AbstractTaskOrProject)
pass
class Project(AbstractProject)
pass
class SubProject(AbstractProject)
pass
class Task(AbstractTaskOrProject)
pass
now the strange thing is that a Project instance has the following *_set
backward relationships:
* task_set
* abstractproject_set
but there is no subproject_set at all.
The only thing I have is Project.subproject which is
Subproject.DoesNotExist, given the OneToOneRelationship of the model
inheritance. So this part is clear.
Moreover, if I create a Subproject instance with a given Project as parent,
then clearly mySubproject.parent gives back Parent.
But Project.abstractproject_set is empty.
I would like to get the SubProject instances from a given Project without
running a separate SubProject.objects.filter(parent=myProject). I thought
that SubProject will result in a backward relationship of subproject_set
over the projects, but this did not happen.
Could someone explain me where I get lost in the documentation?
thanks, Viktor
