def get_url(self):
return os.path.join(<EOL>'<STR_LIT>',<EOL>self.get_year(),<EOL>self.get_month(),<EOL>self.get_day()<EOL>)<EOL>
The URL at which the detail page should appear.

By default it is /archive/ + the year in self.year_format + the
month in self.month_format + the day in the self.day_format.
An example would be /archive/2016/01/01/.
