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

Project description

https://badge.fury.io/py/graphene-file-upload.svg

graphene-file-upload

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.

It currently supports Python 2.7 and 3.4+.

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(
      ...
    )
)

Contributing:

If you’d like to contribute, please run the test suite prior to sending a PR.

In order to run the testing environment, create a virtual environment, install tox, and run the tox commands:

python3 -m venv venv
source venv/bin/activate
pip install -r requirements-tox.txt
# You may have to deactivate and reactivate to have access to the tox command,
# depending on your system.

# Run the test suite with the versions of python you have installed
tox -e py27,py34
# Alternatively, if you're using something like pyenv and can easily install
# Multiple versions of python, then try running the following command
tox

# If for some reason you need to recreate the tox environment (e.g. a new
# dependency has been added since you last ran it, add the -r flag to the
# tox command)
tox -r {...additional flags...}

Check out pyenv if you’d like a simple way of installing multiple python versions to test out.

Packaging for PyPi:

Build the distribution.

python3 setup.py sdist bdist_wheel

Upload to PyPi test servers.

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

Upload to PyPi production servers.

twine upload dist/*
