Two select boxes for same model on form

So I've got a form for a Group model

has_many :people, through: :group_persons   
has_many :group_persons

On the form, I want to have two select boxes where the user can select from the same list of People:

<%= f.label "Sub Group A" %>
<%= f.select :group_person_ids, Person.all %>

<%= f.label "Sub Group B" %>
<%= f.select :group_person_ids, Person.all %>

The selected people from each select box will BOTH get written into the group_persons table eventually, but I want them sent back to the controller as separate lists for handling first, so I want my parameters to look something like this:

"group"=>{ "group_persons_subgroup_a"=>"1", "group_persons_subgroup_b"=>"3", "commit"=>"Save"}

What do I need to do in the view to achieve this?

Check out select_tag. It allows you to specify distinct names for your selects and, thereby, your submitted values.

It might look something like :

select_tag "group_persons_subgroup_a", options_from_collection_for_select(Person.all, "id", "name")

That may not be precisely correct, so you'll have to fiddle with it.

BTW, good on you for using Person instead of User. We are more than our role in relation to our computer!
