Hello,

I'm writing a content server to run on my Raspberry Pi and I'll be using Jinja2 as the templating engine. I'm new to Twisted so I'm having a hard time imaging the examples for TwistedMatrix.com scale.

Are there any examples of a fully featured Twisted application that uses Jinja2 or any other templating engine like Mako?

Hi Jo,

You can return a string (e.g. a rendered jinja2 template) from the .render method of an IResource

http://twistedmatrix.com/documents/current/web/howto/using-twistedweb.html#auto6

So when you see a string being returned from a Resource in the docs, you can consider substituting the particulars of the template engine you want to use.

Here's a very simple example of one approach using jinja2:

##  myapp/config.py

#

# Define a jinja2 Environment somewhere

# I specify a PackageLoader to look up templates from the templates folder in the myapp.web.static package

from jinja2 import Environment, PackageLoader

jinja = Environment(loader=PackageLoader('myapp.web.static', 'templates'))

----

## myapp/web/views.py

#

from twisted.web.resource import Resource

from myapp.config import jinja

class MyResource(Resource):

    isLeaf = True    

    template_name = "example.html"

    

    def render_GET(self, request):

        ctx = {

            'content': "Templated content",

            'extra_info': [1, 2, 3, 4, 5, 6]

        }

        template = jinja.get_template(self.template_name)

        

        return template.render(ctx)
