Nested form and AngularJS, duplicated entities

[Mateusz Urban]

Hello!

In my app i have a model Adventure, which has many Quests (and has "accepts_nested_attributes_for :quests, :allow_destroy => true" ). My form for adventure looks like this:

<%= form_for(@adventure) do |f| %>

  <% if @adventure.errors.any? %>

    <div id="error_explanation">

      <h2><%= pluralize(@adventure.errors.count, "error") %> prohibited this adventure from being saved:</h2>

      <ul>

      <% @adventure.errors.full_messages.each do |msg| %>

        <li><%= msg %></li>

      <% end %>

      </ul>

    </div>

  <% end %>

  <%= f.hidden_field :is_special_event, :value => @is_special %>

  <div class="field">

    <% unless @is_special %>

       Minimal player level<br />

      <%= f.number_field :minimal_level %>

    <% end %>

  </div>

  <div class="field">

    Name:<br />

    <%= f.text_field :name, :id => 'adv_name' %>

  </div>

  <div class="field">

    Description<br />

    <%= f.text_area :description, :id => 'adv_desc' %>

  </div>

<br/><h2>Story</h2>

<div id="quests" ng-controller="QuestsController" ng-init="quests = <%= @adventure.quests.to_json %>">

<div ng-repeat="quest in quests">

<%= render 'quest_fields' %>

</div>

<a href="#quest" class="new-quest" ng-click="add()">New +</a>

</div>

  <div class="actions">

    <%= f.submit 'Save', :class => 'submit-btn' %>

  </div>

<% end %>

And the _quest_feilds.html.erb file

<div id="quest-{{$index}}" ng-controller="QuestController" ng-init="quest_index = $index">

<%= hidden_field_tag 'adventure[quests_attributes][{{quest_index}}][order]', :value => '{{$index}}' %>

<br/>Title:<br/>

<%= text_field_tag 'adventure[quests_attributes][{{quest_index}}][title]', '{{quest.title}}', :size => 150, id: 'quest_{{$index}}_title' %>

<br/>Description<br/>

<%= text_area_tag 'adventure[quests_attributes][{{quest_index}}][description]','{{quest.description}}', :cols => 107, :rows => 10, id: 

  'quest_{{$index}}_description' %>

 

And the problem is, when i'm trying to update any Adventure, instead of updating the quests, it keeps old records and is simply adding modified ones. So, instead of two records, when i'll modify the adventure, i have four records. Does anybody have an idea ?

Thanks in advance!
