Hi Nathan!

It’s meant for a rather specific use case where you want to ensure that users belong to a certain group based on a custom field that they filled in on signup.

Let’s say the custom field is “favorite soccer team” and it contains a list of choices. The script runs on a recurring trigger, so users will eventually end up belonging to a group with the same **full name** (not just `name`) as the value they chose, if the group exists.

You can look at the tests for some synthetic examples: [https://github.com/discourse/discourse-automation/blob/main/spec/scripts/add\_user\_to\_group\_through\_custom\_field\_spec.rb](https://github.com/discourse/discourse-automation/blob/main/spec/scripts/add_user_to_group_through_custom_field_spec.rb)
