Goal: Abstract model field should not be equal across models
|
||||
Description
|
||||
|
||||
Consider the following models:
|
||||
class A(models.Model):
|
||||
class Meta:
|
||||
abstract = True
|
||||
myfield = IntegerField()
|
||||
class B(A):
|
||||
pass
|
||||
class C(A):
|
||||
pass
|
||||
If I pull the fields of B and C into a shared set, one will be de-duplicated away, because they compare as equal. I found this surprising, though in practice using a list was sufficient for my need. The root of the issue is that they compare equal, as fields only consider self.creation_counter when comparing for equality.
|
||||
len({B._meta.get_field('myfield'), C._meta.get_field('myfield')}) == 1
|
||||
B._meta.get_field('myfield') == C._meta.get_field('myfield')
|
||||
We should adjust __eq__ so that if the field.model is different, they will compare unequal. Similarly, it is probably wise to adjust __hash__ and __lt__ to match.
|
||||
When adjusting __lt__, it may be wise to order first by self.creation_counter so that cases not affected by this equality collision won't be re-ordered. In my experimental branch, there was one test that broke if I ordered them by model first.
|
||||
I brought this up on IRC django-dev to check my intuitions, and those conversing with me there seemed to agree that the current behavior is not intuitive.

All tests pass. Here's a summary of the changes made to `/tmp/django_repo/django/db/models/fields/__init__.py`:
|
||||
|
||||
### Changes
|
||||
|
||||
**`__eq__`** — Now also compares `self.model` in addition to `self.creation_counter`. Two fields from different models (e.g., inherited from the same abstract parent) will no longer compare as equal.
|
||||
|
||||
**`__hash__`** — Now hashes the tuple `(self.creation_counter, self.model)` instead of just `self.creation_counter`, so fields from different models get different hash values and won't be de-duplicated in sets/dicts.
|
||||
|
||||
**`__lt__`** — Orders primarily by `self.creation_counter` (preserving existing ordering for the common case), and breaks ties by comparing `model._meta.label` when models differ. Returns `False` for truly equal fields (same counter, same model).
