Typing call-overload error about pydash

[dgilland]

From the mypy error, it looks like self.used_assets is being typed as Any by mypy. Does self.used_assets have a type hint set?

@dgilland

This is a jsonfield I use in django self.used_assets

[dgilland]

Is it lacking a type hint? That seems like what's happening, no type hint and can't be inferred so mypy gives it the Any type which then isn't compatible with pydash.assign_with. It looks like used_assets is dict[str, int] so I think self.used_assets just needs to have that type too.

When I cast it as cast(dict[str, int], self.used_assets) there is no change. mypy keeps giving error. That's why I opened this issue. but when I remove the callback, the error is corrected. Very interesting

The problem here seems to be caused by the callback. But I'm not sure about this situation.

Oh, looks like there's a bug in your example:

new_used_assets = pydash.assign_with(
    self.used_assets,
    used_assets,
    callback,
)

Should be:

new_used_assets = pydash.assign_with(
    self.used_assets,
    used_assets,
    customizer=callback,
)

The customizer has to be passed as a keyword argument.
