An argument by itself is not doing anything. If you want to update the attribute status, you can use accept for that.
update :update do
accept [:status]
primary? true
end
You use arguments for values that aren’t attributes e.g. when accepting values you want to set on a related resource or if you want the user to input something you use to calculate attribute values.
update :update do
argument :status, :atom do
allow_nil? false
end
change set_attribute(:status, arg(:status))
primary? true
end
Would also work but is unnecessary if you just accept the attribute
