nested form gets inserted twice on every create

Hi,

I'm trying to 'add appointments with schedules'

so I have

class Appointment < ActiveRecord::Base    has_many :schedules    accepts_nested_attributes_for :schedules, :allow_destroy => true end

and

class Schedule < ActiveRecord::Base   has_paper_trail   belongs_to :appointment end

and my AppointmentsController has this create action

  def create     resource = new_resource     if resource.update_attributes(params[:appointment])       flash[:notice]= "Perfect"     else       flash[:warning]= "Errors"     end   end

and my appointments/new.html.erb looks like

<% semantic_form_for resource,                      :html => { :class => "oxform" },                      :url => resources_url do |form| %>    <%= render :partial => "/appointments/form", :locals => { :form => form } %>    <% form.buttons do %>       <input class="cta button" type="submit" value="Create"/>    <% end %> <% end %>

Finally my _form.html.erb's are like

appointments/_form.html.erb:

<% form.inputs :appointment_form do %>   <%= form.input :title %>   <% form.semantic_fields_for :fields do |fld| %>     <%= fld.input :location %>     <%= fld.input :category %>   <% end %>   <li>     <ul id="schedules">       <% form.fields_for :schedules do |builder| %>         <%= render 'schedule', :fld => builder %>       <% end %>       <li>         <%= link_to_add_schedule("Add Schedule", form, :schedules) %>       </li>     </ul>   </li>

appointments/_schedule.html.erb:

<li class="schedule">   <ol>     <%= fld.input :first_date, :as => :string %>     <%= fld.input :last_date, :as => :string %>     <%= fld.input :all_day_event, :as => :oxboolean %>     <%= fld.input :repeating, :as => :oxboolean %>     <%= fld.hidden_field :id %>     <%= fld.hidden_field :_destroy %>     <%= link_to_function "Drop Schedule", "removeSchedule(this)" %>   </ol> </li>

You in 'the know' already have spotted that I'm trying to use Formtastic and Ian Whites fabulous resources_controller -

Like I said in the subject: when I POST the appointments/new - I get two schedules added every time - even though the params look like this:

Processing AppointmentsController#create (for 127.0.0.1 at 2010-04-28 13:20:00) [POST]   Parameters: {"appointment"=>{"title"=>"og endnu et", "schedules_attributes"=>{"0"=>{"first_date"=>"", "last_date"=>""}}}, "authenticity_token"=>"RO3cWfhF+2wfH6hXzG0HwDByHLcxl9yAOMBLPk0PRaI=", "calendar_id"=>"16"}

Every thing is fine - I just get that extra schedules added to my schedules table - as a way for Rails 2.3.5 to say "thank you" :slight_smile:

Have I involuntarily stepped on a bug - most likely I've just mixed gems and plugins that do not like each other/Rails 2.3.5, or left the obvious 'some statement' untouched, grinning back at me from somewhere deep within vendor/..

Please if someone has the upperhand on this one - throw me rope <:)

Cheers, Walther
