Django: Web Development with Python

Using the get parameter

Now that we have learned how to retrieve a record and we know how to use a URL, we will create a page that will allow us to display the record of a project. To do this, we will see a new URL syntax:

url(r'^project-detail-(?P<pk>\d+)$', 'TasksManager.views.project_detail.page', name="project_detail"),

This URL contains a new string, (?P<pk>\d+). It allows the URL with a decimal parameter to be valid because it ends with \d. The + character at the end means that the parameter is not optional. The <pk> string means that the parameter's name is pk.

The system routing Django will directly send this parameter to our view. To use it, simply add it to the parameters of our page() function. Our view changes to the following:
