static_url calling in Tornado
python, static, tornado, url
Solution
The RequestHandler class has a method get_template_namespace(), documented here. If you click the source link then you'll see how it creates a dictionary where 'static_url' is set to self.static_url.
Problem
I am a beginner to Python and Tornado web framework. When I was studying the template part in the book "Introduction to Tornado", one line confused me: ``` <link rel="stylesheet" href="{{ static_url("style.css") }}"> ``` How can the application know where to call the function `static_url` when there is no library imported to the namespace? I found `static_url()` in Tornado's web module, but I can not figure out how can this function be successfully called in that template file?
