dynamically building URL patterns list

[Rajdeep Rath]

I am trying to build url patterns list dynamically based on condition. However, wherever i append two lists with tuples such as  - [url(r"/", base.MainHandler)] and init the Application, i get weird AssertionError or some other error. isn't this supposed to be a just simple list?

what am I doing wrong?

Also, what is the use case for Custom Routing? Where is it applicable?

You can use it whenever you want something more customizable than what Application does by default. For example, to match in some way other than a regex on the request path, or to nest multiple Applications on one HTTPServer.

You could even use it all the time. I think that's the direction I'd like to go in the future, but right now it's a little cumbersome because there are so many objects to import. It probably needs a little shorthand to become the default mode of operation.

Yes, it's supposed to just be a simple list. Without seeing how you're assembling the list or what AssertionError you're seeing it's hard to say what might be going wrong.

FYI I figured this out on my own, thanks.
