Using interfaces in SerializerMutation

[tuanden0]

I want to using interface with Mutation because there are some fields that I have calculate before return to user.
I can using interface to avoid rewrite code when return a list ojbects or a single object in Query.
But I can't use interface in Mutation to represent data before return to user after create of update it.

So i have to rewrite resolves to create and update.

How can I use interface with Mutation?

When you say interface do you mean the graphene interfaces like how relay.Node gets used?

In any event, I have used both mixin and decorator patterns to recycle code on mutations.

Sample of a decorator that can wrap the resolver method though I would recommend using a mixin if you can:

def mutate_record_history(Mutation):
    resolver = Mutation._meta.resolver
    # go around frozen
    Mutation._meta.__dict__["resolver"] = wrap_mutation_fn(Mutation, resolver)
    return Mutation

Edit: stackoverflow on mixins: https://stackoverflow.com/questions/533631/what-is-a-mixin-and-why-are-they-useful
