'GCM' object has no attribute 'json_request'

[PauloPhagula]

Calling gcm.json_request(...) raises error stating that 'GCM' object has no attribute 'json_request' when that is the way supposed to be used to send messages.

Since flask-gcm is just a wrapper on the python-gcm lib calling that on flask-gcm should just work

Can you provide more context for the error (e.g. stack trace and example code)?

Sure, it something like this.

I have the a config file with all settings, and then create the app using a creator function. My views file imports the gcm instance from init.py and try sending a push notification using the gcm.json_request method. But fails as the method is not there.

Using this same code with python-gcm works fine, I just need to initialise by passing the GCM_KEY by hand

init.py

gcm = GCM()

def create_app():
  app = Flask(__name__)
  cfg = os.path.join(os.getcwd(), 'config.py')
  app.config.from_pyfile(cfg)
  gcm.init_app(app)

config.py

GCM_KEY = '<key here>'

views.py

from . import db, babel, gcm

bp = pages = Blueprint('pages', __name__)

@pages.route('push', methods=['POST'])
def push():
  req = request.get_json(force=True)
  req['endpoint'] = req['endpoint'].replace('https://android.googleapis.com/gcm/send/', '')
  notification = { "title": "Awesome App Update", "message": "Tap here to start the update!"}
  response = gcm.json_request(registration_ids=[req['endpoint']], data=notification)
  return 'OK'
