I'm trying to get a multi select box working with fields_for but am having a
few problems.
My view has ....
<% form_for(@teacher) do |f| %>
<%= f.label :surname %>
<%= f.text_field :surname %>
<% f.fields_for :qualifications do |qual_form| %>
Qualifications: <%= qual_form.select( :id, @qualifications) %>
<% end %>
<%= f.submit %>
<% end %>
Which produces (for the fields_for) ......
<select id="teacher_qualifications_attributes_0_id"
name="teacher[qualifications_attributes][0][id]">
<option value="5">Licence</option>
<option value="1">NPLQ</option>
<option value="3">Teacher's Level One</option>
<option value="4">Teacher's Level Two</option>
<option value="2">Teacher's Rescue Test</option>
</select>
and on submission I have ......
"teacher"=>{"qualifications_attributes"=>{"0"=>{"id"=>"2"}}, "surname"=>""}}
but what I think I really want is a multi select box with the submitted data
looking something like ......
"teacher"=>{"qualifications_attributes"=>{"id"=>["2","3","4"]}},
"surname"=>""}}
Could somebody putme out of my misery, please?
TIA
