Tornado web application is done in subclasses of RequestHandler. The main entry point for a handler subclass is a method named after the HTTP method being handled: get(), post(), etc. Each handler may define define a BaseHandler class that overrides methods such as write_error and get_current_user and then subclass your own BaseHandler instead of RequestHandler for all your specific handlers. Handling request different template paths for different handlers). To load templates from a non-filesystem location, subclass tornado.template.BaseLoader and pass an instance as the template_loader application setting. Compiled

How to create custom model fields Introduction Background theory Writing a field subclass Writing a FileField subclass How to write custom lookups A lookup example A transformer example Writing an efficient assertIs(future_question.was_published_recently(), False) Here we have created a django.test.TestCase subclass with a method that creates a Question instance with a pub_date in the future. We then check the What happened is this: manage.py test polls looked for tests in the polls application it found a subclass of the django.test.TestCase class it created a special database for the purpose of testing it
