This section describes render. Simply render the template to a string and pass it to RequestHandler. write Configuring templates By default, Tornado looks for template files in the same directory as the .py files that refer handlers). To load templates from a non-filesystem location, subclass tornado.template.BaseLoader and pass an instance as the template_loader application setting. Compiled templates are cached by default;

Extending 2. Templates & Placeholders In this tutorial we’ll introduce Placeholders, and we’re also going to show how you can make your own HTML templates CMS-ready. 2.1. Templates You can use HTML templates to multiple templates, with different layouts or built-in components, and choose them for each page as required. A page’s template can be switched for another at any time. You’ll find the site’s templates in
