Subclass DjangoFilterConnectionField

[ethagnawl]

Is anyone aware of a simple way to subclass DjangoFilterConnectionField in order to provide default fields. Something like this:

class Query:
    all_the_things = MyDjangoFilterConnectionField(
    SomeNode,
    # userId is provided by MyDjangoFilterConnectionField 
    # and there's no need to specify it across N Query classes
    # userId=graphene.String()
 )

Looking at the implementation, it seems like this would involve reaching into the internals a bit and, before proceeding down that path, I wanted to see if anyone had already come up with a simple/robust solve for what I imagine is a pretty common use case.

Thanks!

Here's my first pass at doing this. It seems to be working but I'm not familiar enough with the API or making extensive enough use of any of the optional arguments to know if this breaks anything.

class MyDjangoFilterConnectionField(DjangoFilterConnectionField):
