龙卷风：UIModule用于包含缩小的javascript

Question

I'd like to build a Tornado UIModule which would allow me to include a Javascript file but minify it before rendering. Eg

{% module include_jsmin("file.js") %}

My only problem is that I don't seem to find an elegant way to grab hold of the Template Loader for the application.

How would I do that?

Edit : I know about the render_string method in the UIModule but unfortunately the configured path to the templates isn't available.

Found a neat way:

-Configure the tornado application with a tornado.template.Loader using the setting template_loader : make sure to specify the absolute path to the root of your template dir

-Use the render_string in the UIModule to grab hold of file you wish to process

class JsonMinify(UIModule):    
    def render(self, path):
        code=self.render_string(path)
        return slimit.minify(code)
