Setting up an author automatically
The Blameable behavior allows you to update one or more authors' fields automatically. This is primarily used to populate data into the created_by and updated_by fields. Similar to the Timestamp behavior, you can easily specify some special parameters and essential events for this behavior.
Let us return to the example from the previous section. We also have posts in our blog application. For example, let's assume that our blog model is called BlogPost. The model has author_id, the field which points to who created this post, and updater_id, the field which points to who updated it. We would like to populate these attributes automatically during the create/update model events. Now you can learn how to do it.
