Thanks for the responses, and yeah Maciej is correct the m2m
relationship works fine without any errors, it's just that I can only
edit the prey relationship (as Maciej text art does a much better job
of showing than my explanation).
Right now if I add say a "rabbit" I'd have to go to edit every other
animal that is a predator of the rabbit to specify that the rabbit is
prey for those other animals vs just selecting the predators on the
rabbit edit page. Which is obviously less than ideal.
When I try adding a predator field so I have this in my model:
prey = models.ManyToManyField("self", related_name="predator",
symmetrical=False)
predator = models.ManyToManyField("self", related_name="prey",
symmetrical=False)
Then it gives the following errors:
Validating models...
animals.animal: Accessor for m2m field 'prey' clashes with m2m field
'Animal.predator'. Add a related_name argument to the definition for
'prey'.
animals.animal: Reverse query name for m2m field 'prey' clashes with
m2m field 'Animal.predator'. Add a related_name argument to the
definition for 'prey'.
animals.animal: Accessor for m2m field 'predator' clashes with m2m
field 'Animal.prey'. Add a related_name argument to the definition for
'predator'.
animals.animal: Reverse query name for m2m field 'predator' clashes
with m2m field 'Animal.prey'. Add a related_name argument to the
definition for 'predator'.
If this is something the admin interface can't do then any pointers on
how to customize it or where to look for more information would be
great.
Thanks,
