  • Graphene-Django | Open Source Contribution

    This is my contribution to the open-source community library graphene-django. This library acts as an integration layer between Django and the python implementation of GraphQL, graphene. My pull request here was made to address how the library handled Django Proxy Models. Before my fix, the library would hard throw errors when trying to use the library with proxy models. I addressed this issue by updating the code to correctly handle proxy models the same way as base models.
