英文:
Django - VSCode does not recognize foreign key related names and gives error
问题
Post模型有一个外键指向User模型，其related name为posts。
posts = user.posts.all()
^^^^^
Django显然工作正常。但是在VSCode中出现的错误很烦人。
如何让VSCode知道这不是一个错误？
英文:
Post model has a foreign key to User model with posts as its related name.
posts = user.posts.all()
^^^^^
Django works fine obviously. But the error in VSCode is annoying.
How can I make VSCode know this is not an error?

以下是翻译好的代码部分：
这只是一个权宜之计，未来将会改进，但目前解决这个问题的方法是这样的（在mypy插件之外，即在VS Code内置的检查器中）。
from __future__ import annotations
from typing import TYPE_CHECKING
if TYPE_CHECKING:
from django.db.models.manager import RelatedManager
class RelModel(Model):
belongs_to = models.ForeignKey(MyModel, related_name="things")
class MyModel(Model):
if TYPE_CHECKING:
things: RelatedManager[RelModel]
希望这对你有所帮助。如果有任何其他问题，请随时提出。
英文:
So this is a hack and will improve in the future, but this is the way to solve this right now (outside the mypy plugin, i.e in VS codes built in checker)
from __future__ import annotations
from typing import TYPE_CHECKING
if TYPE_CHECKING:
from django.db.models.manager import RelatedManager
class RelModel(Model):
belongs_to = models.ForeignKey(MyModel, related_name="things")
class MyModel(Model):
if TYPE_CHECKING:
things: RelatedManager[RelModel]
