Body
<p>I am n00b as rails is concerned. I am trying yo create a single multimodel form in my first rails3 project. Details are given below:</p> <pre><code>class Item < ActiveRecord::Base # attr_accessible :title, :body has_many :item_reviews, :dependent => :destroy accepts_nested_attributes_for :item_reviews end </code></pre> <p>and</p> <pre><code>class ItemReview < ActiveRecord::Base # attr_accessible :title, :body belongs_to :item end </code></pre> <p>So as clear, an item can have multiple reviews but when I am creating an item, I want at least 1 review for it. So I want to get item and first review in single form while item creation.</p> <p>I am using following view:</p> <pre><code><%provide(:title,'Create')%> <h1> Add an Item review</h1> <div class="row"> <div class="span6 offset3"> <%= form_for (@item) do |f| %> <%= f.label :name %> <%= f.text_field :name %> <% f.fields_for :item_reviews, @item.item_reviews do |ff| %> <%= ff.label :shop_address %> <%= ff.text_field :shop_address %> <% end %> <%= f.submit "Submit", class: "btn btn-large btn-primary" %> <% end %> </div> </div> </code></pre> <p><code><% f.fields_for :item_reviews, @item.item_reviews do |ff| %></code> will not work because there is not item_review associated with <code>@item</code> currently (<code>@item = Item.new</code>) Until I save @item, I can't create new item_review. What should I do in that case.</p> <p>I know one possibility is model independent form but can't I use something above to make life easy.</p> <p><strong>PS:</strong> I am using bootstrap, just in case if that helps.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
