The UrlBase class is an abstract model that has three methods, as follows:

• get_url() retrieves the full URL of the object.
• get_url_path() retrieves the absolute path of the object.
• get_absolute_url() mimics the get_url_path() method.

The get_url() and get_url_path() methods are expected to be overwritten in the extended model class, for example, Idea. You can define get_url(), and get_url_path() will strip it to the path. Alternatively, you can define get_url_path(), and get_url() will prepend the website URL to the beginning of the path.

The rule of thumb is to always overwrite the get_url_path() method.

In the templates, use get_url_path() when you need a link to an object on the same website, as follows:
