That is returning a string expression for your model. I will explain with an example. Consider you were to pull the list of authors in one of your template in a *choice field*. If you do not have a string method your choice field options by default will look like:
- author.objects(1) - author.objects(2) and so on. Basically, you will get a list of objects in return. However, that is not how you would want your users to see. Your users would want to know the text/value/name of the author. That's when you put a string method to your model. Now if you pull the list of objects you will get it as: - James - jack So this method returns a string representation of your model. Hope this helps.
