Python Web Framework Series – Pylons: Part 3 Views with Mako

import logging </p>

from pylons import request, response, session, tmpl_context as c

        self.subject = subject

We’ve added a Post class with basic attributes and placed them in an array in the c.posts variable, also we’ve hardcoded the username “rsvihla”.  I know the more experience developers here are cringing at my awful little Post class, don’t worry its a just a place holder and will be removed later.  The point here is building functionality in steps with test coverage.  Now run nosetests just as before and you should have all tests passing.  For bonus measure refresh http://127.0.0.1:5000 .

Base Layouts

We’ve built a very basic page now, but suppose we want to build several and have some bits of information show up over and over again, like user name or menu structure.

create a base template named “base.mako” in the templates directory that has the following in it:
