Keeping permissions in sync

The permissions associated with each role are persisted in the database. This means we will need to make sure that the permissions we created while developing the application are kept in sync when we move to a new environment or when we seed the database with a new role.

To keep the permissions in sync, we will again make use of the bootstrap function. We can add a new function that will enable permissions for a specific role when the server starts up. Let's get coding, as follows:
