Working with customized pagination classes

We enabled pagination to limit the size for the result sets. However, any client or user is able to specify a large number for the limit value, such as 10000, and generate a huge result set. In order to specify the maximum number that is accepted for the limit query parameter, it is necessary to create a customized version of the limit/offset pagination scheme that the Django REST framework provides us.

We made changes to the global configuration to use the rest_framework.pagination.LimitOffsetPagination class to handle paginated responses. This class declares a max_limit class attribute whose default value is equal to None, which means there is no upper bound for the limit value. We will indicate the upper bound value for the limit query parameter in the max_limit class attribute.

Make sure you quit Django's development server. Remember that you just need to press Ctrl + C in the terminal or Command Prompt in which it is running.
