问题
I have a profile page for my users where they should be able to update their information. For now they can update their names but I also want phonenumbers, addresses, etc.
The code for updating the name of my user is
class AccountPage(BaseRequestHandler):
def get(self):
self.render('accountpage.html', {'request': self.request, 'user': self.current_user,'loggedin': self.logged_in, 'session': self.auth.get_user_by_session(),})
def post(self):
user = self.current_user
user.name = self.request.POST['name']
user.put()
self.auth.set_session(
self.auth.store.user_to_dict(user))
self.render('accountpage.html', {'request': self.request, 'loggedin': self.logged_in,'user': self.current_user})
But how can I use extra variables such as phonenumbers, address variable etc? The webapp2 User model is an expando model. It did not work to just add the variables to the model:
class User(model.Expando):
"""Stores user authentication credentials or authorization ids."""
#: The model used to ensure uniqueness.
unique_model = Unique
#: The model used to store tokens.
token_model = UserToken
created = model.DateTimeProperty(auto_now_add=True)
updated = model.DateTimeProperty(auto_now=True)
# ID for third party authentication, e.g. 'google:username'. UNIQUE.
auth_ids = model.StringProperty(repeated=True)
# Hashed password. Not required because third party authentication
# doesn't use password.
password = model.StringProperty()
phonenumber = model.StringProperty()
address = model.StringProperty()
I use simpleauth and I get this error msg from simpleauth:
INFO 2015-07-20 06:09:34,426 authhandlers.py:78] user_dict | {'name': u'DAC', 'user_id': 5620703441190912, 'token': u'c9BbE72EmrgTDpG1Dl4tlo', 'token_ts': 1437371676, 'cache_ts': 1437371676, 'remember': 0}

In my BaseRequestHandler I have this cached_property that creates an object.
@webapp2.cached_property
def current_user(self):
"""Returns currently logged in user"""
user_dict = self.auth.get_user_by_session()
logging.info('user_dict | %s ' % user_dict)
if user_dict:
return self.auth.store.user_model.get_by_id(user_dict['user_id'])
else:
return api.users.get_current_user()
Then I tried changing the user model but I still get the ERR phone_number when making these changes.
class BaseRequestHandler(webapp2.RequestHandler):
class User(auth_models.User):
address = ndb.StringProperty(indexed=False)
phone_number = ndb.IntegerProperty(indexed=False)
def dispatch(self):
# Get a session store for this request.
self.session_store = sessions.get_store(request=self.request)
if self.request.host.find('.br') > 0:
i18n.get_i18n().set_locale('pt-br')
elif self.request.host.find('klok') > 0:
i18n.get_i18n().set_locale('sv')
elif self.request.host.find('business') > 0:
i18n.get_i18n().set_locale('en')
else:
lang_code_get = self.request.get('hl', None)
if lang_code_get is None:
lang_code = self.session.get('HTTP_ACCEPT_LANGUAGE', None)
lang_code_browser = os.environ.get('HTTP_ACCEPT_LANGUAGE')
if lang_code:
i18n.get_i18n().set_locale(lang_code)
if lang_code_browser and lang_code is None:
self.session['HTTP_ACCEPT_LANGUAGE'] = lang_code_browser
i18n.get_i18n().set_locale(lang_code_browser)
else:
i18n.get_i18n().set_locale(lang_code_get)
try:
# Dispatch the request.
logging.info('trying to dispatch')
webapp2.RequestHandler.dispatch(self)
except Exception, ex:
logging.error(ex)
self.error(404)
finally:
# Save all sessions.
self.session_store.save_sessions(self.response)
@webapp2.cached_property
def jinja2(self):
"""Returns a Jinja2 renderer cached in the app registry"""
return jinja2.get_jinja2(app=self.app)
@webapp2.cached_property
def session(self):
"""Returns a session using the default cookie key"""
return self.session_store.get_session()
@webapp2.cached_property
def auth(self):
return auth.get_auth()
@webapp2.cached_property
def session_store(self):
return sessions.get_store(request=self.request)

def auth_config(self):

As mentioned in the comment above - you should NOT be making any changes in any of the built-in libraries, instead, you can extend them and then add any additional code/properties you need.
So first, you'd need to define your own User model, which would look simmilar to this:
from google.appengine.ext import ndb
import webapp2_extras.appengine.auth.models as auth_models
class User(auth_models.User):
address = ndb.StringProperty(indexed=False)
phone_number = ndb.IntegerProperty(indexed=False)
You are only adding the new properties you need or the ones you need to override, so no created / updated / etc as they're inherited from the model you were referring to.
You then need to work with this model inside your BaseRequestHandler class (I'm not sure what the line self.current_user does, you might need to include the code for that as well).
You can also read this article to get some more ideas: http://gosurob.com/post/20024043690/gaewebapp2accounts
