Graphene: PyMongo and/or Mongoengine Integration

[sibelius]

It should be useful to have a mongoengine easy integration

[msoedov]

As temporary workaround I used https://github.com/msoedov/flask-graphql-example/blob/master/ql.py#L13-L20

    def resolve_user(self, args, info):
        u = User.objects.get(email=args.get('email'))
        return construct(UserField, u)

Hello, I started a project for MongoEngine integration

https://github.com/dmzkrsk/graphene-mongoengine

I copied code from contrib.django and contrib.sqlalchemy and replaced classes with mongoengine ones.

It's in pretty early stage, I have no docs, tests, but it has working fields, relations, relay. Mutations not tested yet.

Please join, test on your projects, add tests, etc

@dmzkrsk that's great to know

take a look at https://github.com/RisingStack/graffiti-mongoose, it's have the same ideia but for JS

Hi is there any movement on this issue to the best of your knowledge @syrusakbary @dmzkrsk?
This seems to be almost an year old request.

[ozanturksever]

i did a impl here https://github.com/ozanturksever/graphene-mongoengine
it is mostly code modifed from graphine-django

[gordol]

wheee, nobody did tests in their implementations.

[yfilali]

FYI: https://github.com/yfilali/graphql-pynamodb is a recent implementation for dynamodb, Amazon's NoSQL database. I am not too familiar with mongodb, but the basic structure should be very similar to @ozanturksever implementation. I also had the need to implement relationship attributes. So maybe that could be of use to the mongo port. The MongoDB documentation on "Model One-to-Many Relationships with Document References" seems pretty close to the pattern I ended up implementing: https://docs.mongodb.com/v3.0/tutorial/model-referenced-one-to-many-relationships-between-documents/

[syrusakbary]

As of the time of writing, there are two Graphene-MongoEngine integrations:
https://github.com/tomasgarzon/graphene-mongoengine by @tomasgarzon
https://github.com/ozanturksever/graphene-mongoengine by @ozanturksever

Would love to integrate one or another into the graphql-python community.

Closing the issue, but please comment if you would like to be the official maintainer for graphene-mongoengine in the graphql-python community.

[gordol]

hmm, seems to me that neither of those implementations are complete... not all object types are supported, for example, and relations are also not supported by either implementation.

[abawchen]

Hello,

After checking, these 2 repos
https://github.com/tomasgarzon/graphene-mongoengine
https://github.com/ozanturksever/graphene-mongoengine
does not support graphene 2.0 and neither relationship.

So I start https://github.com/abawchen/graphene-mongo, which supports one-to-one with ReferenceField and one-to-many with List(ReferenceField), and I have some basic test cases as well.

Hope it helps.

Thanks @tomasgarzon & @ozanturksever, got a lot from your implementation! :beers:

Based on @abawchen initiative, we started the official repo Graphene-mongo that @abawchen will be leading.

Any more contributors will be welcome, so please write here if anyone is interested.
