Pylons Quickie: I want to use distance_of_time_in_words

May 17, 2009 § Leave a comment

distance_of_time_in_words is a useful function that converts boring looking datetime into something more attractive (and SEO optimized) like: 30 seconds ago.

Pylons gain this functionality via WebHelper which blatantly inspired by Rails.

But, out of the box, this functionality does not exists in my templates. To enable it, I need to add this line in helpers.py:

from webhelpers.date import distance_of_time_in_words

May 15, 2009 § Leave a comment

distinct() method is accessible from Query object. The documentation is kind of obscure, so hopefully this post is helpful for others.

Example:

 @classmethod
def get_all_category(cls):
return meta.Session.query(cls.category).distinct().all()

So, I created 3 minutes tutorial on how to define the ORM class using declaration_base(), build that table, populates, and fetch.

See code here.

April 27, 2009 § Leave a comment

I want to store python object to JSON. Including a complex one (not just object that contains simple attributes).

Apparently, John Paulett has a need for that too. Here’s his code. The best part is: It uses CJSON! Bingo.

Python: using Memcache Client

April 23, 2009 § Leave a comment

For some reason, it’s always hard to find example on how to create memcache client object using Python.

This time, I will remember:

import memcache
memc = memcache.Client(['127.0.0.1:11211'])

Where Am I?
