graphene-file-upload 1.0.0a2

Lib for adding file upload functionality to GraphQL mutations in Graphene Django and Flask-Graphql

graphene-file-upload is a drop in replacement for the the GraphQL view in Graphene for Django, and for Flask-Graphql. It supports multi-part file uploads that adhere to the Multipart Request Spec.

Installation:

pip install graphene-file-upload

Usage

To add an upload type to your mutation, import and use Upload. Upload is a scalar type.

from graphene_file_upload.scalars import Upload

class UploadMutation(graphene.Mutation):
    class Arguments:
        file = Upload(required=True)

    success = graphene.Boolean()

    def mutate(self, info, file, **kwargs):
        # do something with your file

        return UploadMutation(success=True)

Django Integration:

To use, import the view, then add to your list of urls (replace previous GraphQL view).

from graphene_file_upload.django import FileUploadGraphQLView

urlpatterns = [
  url(r'^graphql', FileUploadGraphQLView.as_view(graphiql=True)),
]

Flask Integration:

Note that flask-graphql version <2.0 is not supported. At the time of writing this README, you must install flask-graphql with pip install --pre flask-graphql

Simply import the modified view and create a new url rule on your app:

from graphene_file_upload.flask import FileUploadGraphQLView

app.add_url_rule(
    '/graphql',
    view_func=FileUploadGraphQLView.as_view(
      ...
    )
)

Testing:

TO-DO, still need to write tests for Django and Flask views.

python3 setup.py sdist bdist_wheel

Upload to PyPi test servers.

twine upload --repository-url https://test.pypi.org/legacy/ dist/*
