Hello, I started to write a simple todo app with couchcb. But as usual I met an error which a search in the internet could not help. I don’t even know how `g` gets its properties. My app:
from flask import Flask, render_template, request, g from flaskext.couchdb import CouchDBManager app = Flask(__name__) # DB config app.config['COUCHDB_SERVER'] = 'http://127.0.0.1:5984' app.config['COUCHDB_DATABASE'] = 'todo-webapp' @app.route('/') def index(): print(dir(g)) document = dict(title="Hello", content="Hello, world!") g.couch['users'] = document return render_template('index.html') if __name__ == '__main__': manager = CouchDBManager() manager.setup(app) manager.sync(app) app.run(debug=True) And when I refresh the page from http://127.0.0.1:5000/ ,, I get an error: ['__class__', '__contains__', '__delattr__', '__dict__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__iter__', '__le__', '__lt__', '__module__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', '__weakref__', 'get', 'pop', 'setdefault'] 127.0.0.1 - - [01/May/2019 17:20:13] "GET / HTTP/1.1" 500 - Traceback (most recent call last): File "/Users/aruprakshit/projects/flask-apps/todo-app/venv/lib/python3.7/site-packages/flask/app.py", line 2309, in __call__ return self.wsgi_app(environ, start_response) File "/Users/aruprakshit/projects/flask-apps/todo-app/venv/lib/python3.7/site-packages/flask/app.py", line 2295, in wsgi_app response = self.handle_exception(e) File "/Users/aruprakshit/projects/flask-apps/todo-app/venv/lib/python3.7/site-packages/flask/app.py", line 1741, in handle_exception reraise(exc_type, exc_value, tb) File "/Users/aruprakshit/projects/flask-apps/todo-app/venv/lib/python3.7/site-packages/flask/_compat.py", line 35, in reraise raise value File "/Users/aruprakshit/projects/flask-apps/todo-app/venv/lib/python3.7/site-packages/flask/app.py", line 2292, in wsgi_app response = self.full_dispatch_request() File "/Users/aruprakshit/projects/flask-apps/todo-app/venv/lib/python3.7/site-packages/flask/app.py", line 1815, in full_dispatch_request rv = self.handle_user_exception(e) File "/Users/aruprakshit/projects/flask-apps/todo-app/venv/lib/python3.7/site-packages/flask/app.py", line 1718, in handle_user_exception reraise(exc_type, exc_value, tb) File "/Users/aruprakshit/projects/flask-apps/todo-app/venv/lib/python3.7/site-packages/flask/_compat.py", line 35, in reraise raise value File "/Users/aruprakshit/projects/flask-apps/todo-app/venv/lib/python3.7/site-packages/flask/app.py", line 1813, in full_dispatch_request rv = self.dispatch_request() File "/Users/aruprakshit/projects/flask-apps/todo-app/venv/lib/python3.7/site-packages/flask/app.py", line 1799, in dispatch_request return self.view_functions[rule.endpoint](**req.view_args) File "/Users/aruprakshit/projects/flask-apps/todo-app/app.py", line 14, in index g.couch['users'] = document File "/Users/aruprakshit/projects/flask-apps/todo-app/venv/lib/python3.7/site-packages/werkzeug/local.py", line 348, in __getattr__ return getattr(self._get_current_object(), name) AttributeError: '_AppCtxGlobals' object has no attribute ‘couch' Can anyone help me to fix this?
