Validator's first agument warning when using @pydantic.validator

[earthpyy]

Describe the bug PyCharm is not seeing validator function as a class method when using @pydantic.validator instead of @validator

To Reproduce Steps to reproduce the behavior:

1. Define a pydantic model
2. Define avalidator function using @pydantic.validator(...) as a decorator instead of using @validator(...)
3. See error

Expected behavior PyCharm should not warn about using self instead cls since validator() returns class method

@earthpyy I'm sorry for my late reply. I can't reproduce your warning.

Would you please give me the code?

@koxudaxi Hello, I just tried to reproduce and found that the import statement was import pydantic.generics instead of import pydantic. I think because the other place in the same file was using pydantic.generics.Generic.

I also found that it isn't practical to import like that and using pydantic.validator later. Changing the import statement back to import pydantic works. I'm not sure if there is anything to fix in this case. Thanks!

That's good news. I'm happy to resolve your problem.

I don't close this issue now. If I get the time then I will check the problem deeply.
