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)
