KeyError: 'security' in Flask_security?
flask, flask-security, peewee, python
Solution
You need to initialize the extension for your app.
security = Security()
security.init_app(app, user_datastore)
See the quickstart in the docs.
Problem
I'm building a website using Flask in which I'm now trying to use Flask_Security for token based authentication. I now want to get an auth_token from the user, for which I use the get_auth_token() method. Unfortunately I get the stacktrace below this message. Does anybody know what's wrong? All tips are welcome! ``` Traceback (most recent call last): File "/usr/local/lib/python2.7/dist-packages/flask/app.py", line 1836, in __call__ return self.wsgi_app(environ, start_response) File "/usr/local/lib/python2.7/dist-packages/flask/app.py", line 1820, in wsgi_app response = self.make_response(self.handle_exception(e)) File "/usr/local/lib/python2.7/dist-packages/flask/app.py", line 1403, in handle_exception reraise(exc_type, exc_value, tb) File "/usr/local/lib/python2.7/dist-packages/flask/app.py", line 1817, in wsgi_app response = self.full_dispatch_request() File "/usr/local/lib/python2.7/dist-packages/flask/app.py", line 1477, in full_dispatch_request rv = self.handle_user_exception(e) File "/usr/local/lib/python2.7/dist-packages/flask/app.py", line 1381, in handle_user_exception reraise(exc_type, exc_value, tb) File "/usr/local/lib/python2.7/dist-packages/flask/app.py", line 1475, in full_dispatch_request rv = self.dispatch_request() File "/usr/local/lib/python2.7/dist-packages/flask/app.py", line 1461, in dispatch_request return self.view_functions[rule.endpoint](**req.view_args) File "/home/kramer65/myapp-kram/app/views/apiviews.py", line 33, in api_login return jsonify({'token': user.get_auth_token()}) File "/usr/local/lib/python2.7/dist-packages/flask_security/core.py", line 313, in get_auth_token return _security.remember_token_serializer.dumps(data) File "/usr/local/lib/python2.7/dist-packages/werkzeug/local.py", line 338, in __getattr__ return getattr(self._get_current_object(), name) File "/usr/local/lib/python2.7/dist-packages/werkzeug/local.py", line 297, in _get_current_object return self.__local() File "/usr/local/lib/python2.7/dist-packages/flask_security/core.py", line 30, in <lambda> _security = LocalProxy(lambda: current_app.extensions['security']) KeyError: 'security' ```
