seriousdjangographene 0.5.1

https://github.com/serioeseGmbH/serious-django-graphene
serious-django-graphene offers a couple of extensions for Graphene development in Django.

get_user_from_info returns the request’s user from the passed info object.
We use this function all the time, for example, to do permission checks on the current user.

FormMutation is based on FailableMutation (see below).
It defines a Graphene mutation based on a plain old Django form. What is this good for?
Well, we want to employ the builtin capabilities of Django for input validation and
conversion. Why reinvent the wheel to do checks like “string of max length 50” inside
Graphene mutations when Forms can do that for you, and have extensible validators?
This is essentially a cleaned up and changed version of the FormMutation delivered with
graphene-django itself. The difference is mainly in how we model the returned data in an
expectable pattern, see FailableMutation.

FailableMutation defines a mutation that contains:

A success boolean flag
An error value, present only if an error occurred, which is (a union of) either

A list of ValidationError in the format like Django returns for validation errors, or
An ExecutionError, which just contains an error_message String.

If you need additional fields, add them by inheriting from FailableMutation.

make_failable_objecttype turns an existing graphene.ObjectType into a Field that contains:

A result field which is an optional value of the original type
A error field which is an optional String value, present only if an error occurred
A success boolean flag field. Strictly seen, this is superfluous, as the null-ness of
result or error can be checked. However, its existence improves semantics on the
client, as they can now just check if(result.success) { ... }.
