Get Recommendations

note

This tutorial assumes you already have a server.py file with Python Flask and PyMongo set up. If you haven't already, read the Overview before reading this section.

When a user wants to view recommended games, we retrive the information with the following steps:

1. The request passes the user's email as a query.
2. Use MongoDB's find_one to find the user by email. Return 404 error if not found.
3. Else, return the result of the predict function.

The code will be as follows:

@app.route('/game', methods=["GET"])

def get_game():

email = request.args.get('email') #user ID

user = User.find_one({'email': email})

if not user:

abort(404)

# get new recommendations

return jsonify(predict(email))
