Question

I have a model that has

attr_accessible :name, :activity

validates :name, uniqueness: { scope: :activity }

It works and it doesn’t allow the creation of duplicate entries. But with simple_form it only shows the error on the :name field. I’d like it to have errors on both fields saying that this ‘name’ and ‘activity’ combination has already been taken.

I’m thinking I need to create a custom validation method, but I’m hoping there’s a more elegant solution that I’ve overlooked so far.

Is there a way to show errors on both these fields?

Answer 1

I ended up doing

validates :name, uniqueness: { scope: :activity, message: 'This name and activity combination has already been taken.' }

I haven’t decided if I’m going to have it validate both and put the message on both fields yet, but that opposite for the :activity field would be the same.
