Reference implicit model types in mutations #59
Description
Various types get automatically generated for models, for example "create" and "update" types, like CreateUserInput. Often it's necessary to reference these types in custom mutations, but of course they've not been generated by then. Not to mention we don't know which API will be used.
A placeholder set of types must be created to be used. I would expect the usage to look something like:
class MyMutation(model.Mutation):
input = MyModel.Meta.CreateInput
