Defining custom feature flags


In this document the process of implementing custom feature flags is presented. In the subsequent sections we will create a feature flag that is enabled if it’s number field is odd.

Functions to be implemented

Each feature flag requires 1 function to be implemented:

However, it is recommended to additionally include:

Create feature flag function

Let’s start with a construction method that will use create a base feature flag, add the number field to it and assign it to the proper class.

Class checking function

Next, we will create a function checking the class attribute of the object.

is_enabled function

Finally, we define the is_enabled function which checks whether the number field of our flag is odd.

Now, let’s test if everything is working
