    copied!<p>I'm running into to a issue with a nested form which I'm sure should be easily solved, yet I can't find a way around it</p> <p>Basically I have the following relationship</p> <pre><code>event has_many :contacts =&gt; through :event_contacts </code></pre> <p>the nested form works perfectly as long as I'm creating new contacts each time. </p> <p>If I include a drop down to allow selection of an existing contact within the nested form, an event is created, however the contact_id is nil in the event_contacts table.</p> <p>No contact is created, since I post an 'id' field for the nested contact.. (ie .new_record? returns false.)</p> <p>So how do I update the event_contacts table to ensure that the 'selected' contacts is properly associated?</p> <p>See snipbits below...</p> <p><strong>Models</strong></p> <pre><code>class Event &lt; ActiveRecord::Base belongs_to :user has_many :event_contacts accepts_nested_attributes_for :event_contacts has_many :contacts, :through =&gt; :event_contacts accepts_nested_attributes_for :contacts class EventContact &lt; ActiveRecord::Base belongs_to :event belongs_to :contact accepts_nested_attributes_for :contact class Contact &lt; ActiveRecord::Base belongs_to :user has_many :event _contacts has_many :events, :through =&gt; :event_contacts </code></pre> <p><strong>View</strong></p> <pre><code>- fields_for(@event) do |f| - f.fields_for :event_contacts do |rc| - rc.fields_for :contact do |c| = c.collection_select :id, Contact.all, :id, :name, { :selected =&gt; @contact.id || 0 } = c.hidden_field :user_id, :value =&gt; @current_user.id = c.text_field :first_name = c.text_field :email </code></pre>
