This example project demos integration between Graphene, Flask and SQLAlchemy.
The project contains two models, one named Department
and another
named Employee
.
First you'll need to get the source of the project. Do this by cloning the whole Graphene-SQLAlchemy repository:
# Get the example project code
git clone https://github.com/graphql-python/graphene-sqlalchemy.git
cd graphene-sqlalchemy/examples/flask_sqlalchemy
It is good idea (but not required) to create a virtual environment for this project. We'll do this using virtualenv to keep things simple, but you may also find something like virtualenvwrapper to be useful:
# Create a virtualenv in which we can install the dependencies
virtualenv env
source env/bin/activate
Now we can install our dependencies:
pip install -r requirements.txt
Now the following command will setup the database, and start the server:
./app.py
Now head on over to http://127.0.0.1:5000/graphql and run some queries!
