Some clarity on how to define abstract types

[fhennig]

I have different entities in my project, and want to split up my Query ObjectType into multiple classes.

How should I do that?

There seem to be three ways of doing it:

1. Just use inheritance as usual:

class UserQueries(graphene.ObjectType):
    ...

class OtherQueries(graphene.ObjectType):
    ...

class Queries(UserQueries, OtherQueries):
    pass

2. Using the AbstractType:

class UserQueries(graphene.AbstractType):
    ...

class OtherQueries(graphene.AbstractType):
    ...

class Queries(graphene.ObjectType, UserQueries, OtherQueries):
    pass

3. Using the abstract = True attribute:

class UserQueries(graphene.ObjectType):
    class Meta:
        abstract = True
    ...

class OtherQueries(graphene.ObjectType):
    class Meta:
        abstract = True
    ...

class Queries(UserQueries, OtherQueries):
    pass

And this can apparently also be given as a class argument like so:

class UserQueries(graphene.ObjectType, abstract=True):
    ...

The documentation says to use 2., but in the v2 release notes it says that AbstractType is deprecated. In the same document it uses method 3., but I couldn't find any documentation for that.

I started to just use normal inheritance and it seems to work.

How should it be done?

Probably related to #823

If you are on Python3, you can use abstract=True without any problems. I believe AbstractType is your only option on Python2.

I'm confused. "abstract = True" isn't mentioned anywhere in the Graphene docs. Is that an official object option, and what behavior does it result in?
