How do you set a custom id when using a check_box_tag helper in rails?
I have a loop which creates a bunch of checkboxes based on a collection:
- subject.syllabus_references.each do |sr|
= check_box_tag 'question[syllabus_reference]', sr.id, :id => sr.id
= label_tag sr.id, sr.name
I would like to set a custom id so that my Label for the checkbox works correctly but I can't seem to figure out how (:id => sr.id does not work...).
The problem might also be with the way I've defined the label, so if I can get that to reference the correct check box without setting a custom id then that would be fine also...
I used this in my application to create checkbox tags from collection and submit an array of them:
<% @cursos.each do |c| %>
<span class='select_curso'>
<%= check_box_tag "vaga[curso_ids][]",
c.id, (checked = true if form.object.curso_ids.include?(c.id)) %>
<%= label_tag "vaga[curso_ids][][#{c.id}]", c.nome %>
</span>
<% end %>
So in params, I have an array "curso_ids"=>["1", "3", "5"] instead of a string "curso_ids"=>"5". If you want to return a single value, use vaga[curso_id], otherwise use vaga[curso_ids][] to return an array.
