Building the Twitter voting application

Now we have our environment set up and we have seen how to create an app on Twitter and perform three-legged authentication, it is time to get right into building the actual application that will count the Twitter votes.

We start off by creating a model class that will represent a hashtag. Create a file called hashtag.py in the twittervotes/core/twitter directory with the following content:

class Hashtag:
    def __init__(self, name):
        self.name = name
        self.total = 0
        self.refresh_url = None

This is a very simple class. We can pass a name as an argument to the initializer; the name is the hashtag without the hash sign (#). In the initializer, we define a few properties: the name, which will be set to the argument that we pass to the initializer, then a property called total that will keep the hashtag usage count for us...
