37310	MediaAsset instances with attributes violate equality/hash contract with strings	miladkhoshdel	miladkhoshdel	"After the fix for #37088, `MediaAsset.__eq__()` still considers an asset equal to a string containing the same path, while `MediaAsset.__hash__()` includes the asset's attributes.

This violates Python's requirement that equal objects have equal hashes.

Reproduction on Django 6.2.dev20260831204047:

{{{#!python
from django.forms import Script

asset = Script(""/static/app.js"", defer=True)
path = ""/static/app.js""

print(asset == path)
print(hash(asset) == hash(path))
print(path in {asset})
}}}

Output:

{{{
True
False
False
}}}

Although `asset == path`, a set cannot find `path` because the two objects are placed in different hash buckets. Dictionary lookups can be affected in the same way. `Stylesheet` instances with attributes have the same issue.

Expected behavior: Whenever `asset == path`, `hash(asset) == hash(path)`.

This appears to be a regression introduced by bc9bed573ce39c3b739a4a3b7848816d464b6bdc for #37088 in Django 6.1.

A possible fix is to hash only `self._path`. Assets with the same path but different attributes may then share a hash while remaining unequal, which is valid Python behavior."	Bug	assigned	Forms	6.1	Normal		MediaAsset hash equality	Johannes Maron	Unreviewed	0	0	0	0	0	0
