How to do SEO Url changes and Redirects for google AppEngine Webapp2 Urls?
python,google-app-engine,webapp2

Uploading Files in webapp2/GAE

The content of uploaded files is in self.request.POST in your handler, so you can get that content (assuming e.g the field for the uploaded file is named 'foo') with e.g content = self.request.POST.multi['foo'].file.read() So now you have the content as a string -- process it as you wish. This does...
app engine update all sessions for user
google-app-engine,webapp2,gae-sessions
I think storing in database and doing a query on each request is the most natural option. Don't know about your full requirements and specifications, but for keeping the sessions synchronized I think a solution like firebase makes a lot of sense, though it might be overkill in your case....

Instantiating WSGIApplication in webapp2
webapp2 does some magic on routes (converting from the tuples to webapp2.Route instances). When you just assign to routes, it won't work because they haven't been converted to the right format for webapp2. I believe you can just add in the Route instantiation and it should work.

GAE webapp2 delete all UserTokens (drop all sessios) for specific user
python,google-app-engine,webapp2
I see two ways how to do that. First is to inherit from the UserToken class making user an indexed property. Then you can set the token_model class property to your new token model in your user class. Here is the code: class MyToken(UserToken): user = ndb.StringProperty(required=True) class MyUser(User): token_model...

Using App Engine Cloud Endpoints to access ndb datastore
python,google-app-engine,google-cloud-endpoints,webapp2,google-datastore
Yes, that's a perfectly reasonable approach. If you are using Cloud Endpoints and NDB, you may want to look at the Endpoints Proto Datastore API which takes some of the legwork out of serializing your NDB Model entities. Personally, I didn't find the API very intuitive so I reverted to...
Google app engine: fetching a lot of urls and data processing

Using Google App Engine Property's verbose_name in jinja2
python,google-app-engine,jinja2,webapp2
For starters, the purpose of verbose_name is to use it in the label, not as the name of the input. It's better if the name matches the model (for clarity and future automation), and I don't think it'll change often (if at all), because that requires a lot of work...

Google appengine memcache scope
python,google-app-engine,webapp2
Memcache instance is global and not tight to the User instance.

How do I pass multiple variables from one handler to another in GAE?
