In this 10th Django web development with Python tutorial, we're going to cover creating more dynamic URLs. In our case, we need to have URL handling for a URL that has something like /blog/2/, where the 2 corresponds to the 2nd blog post.
As you may have guessed, Django saw this coming, and has you covered. In our case, and in many cases, the 2 is the table's Primary Key. A primary key is a unique identifier per table in a database, no other entry should have the same primary key as another. Because of this, having a Primary Key makes for an easy way to lookup elements and is common practice. Because of this, Django has built this premise in quite deeply.
