I deployed one simple project on Google App Engine and there the project is working. Before I was able to get list of users from datastore through the remote API console , but now this no longer works. To start the remote API console I'm connecting this way (running from the project directory):
../../+/google_appengine_PYTHON_SDK/remote_api_shell.py -s project.appspot.com
I found that the easiest way to load all modules is to run:
s~project> help()
help>modules
help>quit
After that I try to get the list of users:
s~project> from app.models import User
s~project> User.query().fetch()
The last row results in this:
WARNING:root:suspended generator _run_to_list(query.py:964) raised RuntimeError(working outside of application context)

I'm very new to python. I found http://kronosapiens.github.io/blog/2014/08/14/understanding-contexts-in-flask.html but couldn't understand from this how to start working inside the app context.
I have tried on linux with python versions:
I have tried with google app engine SDK versions:
The problem was in the User class itself. There I have:
def __init__(self, **kwargs):
super(User, self).__init__(**kwargs)
# FLASKY_ADMIN configuration variable, so as soon as that email address appears in a registration request it can be given the correct role
if self.role is None:
print ("there is no role for this user")
if self.email == current_app.config['MAIL_ADMIN']:
self.role = ndb.Key('Role', 'administrator')
the problematic line is this line:
if self.email == current_app.config['MAIL_ADMIN']:
I don't know how to manage to make it work with this line so I've removed it and now the user is retrieved.
