webapp2

问题 I have a long-running process in a task queue that is causing a DeadlineExceededError because the task can take longer than 10 minutes. As I described in this question, the long-running process has a for loop that sequentially calculates new values in large dictionaries that are used to create kml files. The task currently looks like this: class longprocess_handler(webapp2.RequestHandler): def post(self): #This is currently one task that recursively uses data in dictionaries to #produce kml

问题 Google appengine's webapp2 has a very cryptic documentation regarding the handling of uploaded files. Uploaded files are available as cgi.FieldStorage (see the cgi module) instances directly in request.POST.

问题 When I blog, I like to separate each blog-post into its own .html file (is that ok?) This prevents the file getting too big, and makes it easy to go back and edit a previously written blog post if need be. Occasionally the blog post will contain css/js/ajax/template variables. But on my website, I like all the blog posts on one page (so I can scroll through them all, instead of going to a separate page for each post) Here is an html file that contains two blog posts: {% extends "base.html" %}

问题 I'm using the google app engine for a basic app. The scenario is simple: i click Logout and I want my Logout handler to redirect me back to the page from where I came from.
