Rails 4 Form: has_many through: checkboxes

Question

Original question

Two resources: users and animals. When creating a user, the client selects check boxes to say how many

Answer 1

collection_check_boxes is a better option:

<%= f.collection_check_boxes(:animal_ids, Animal.all, :id, :name) do |animal| %>
  <%= animal.label { animal.check_box } %>
<% end %>
