    <p>For my form I am using my <code>Product</code> model:</p> <pre><code>class Product &lt; ActiveRecord::Base attr_accessible :purchase_date, :send_to_data end </code></pre> <p>On my form I have the <code>:purchase_date</code> working correctly when I create multiple products but also want to make the radio_button_tag do the same:</p> <pre><code>&lt;%= form_tag create_multiple_products_path, :method =&gt; :post do %&gt; &lt;%= date_select("product", "purchase_date") %&gt; &lt;%= radio_button_tag(:send_to_data, 1) %&gt; &lt;%= radio_button_tag(:send_to_data, 0) %&gt; &lt;% @products.each_with_index do |product, index| %&gt; &lt;%= fields_for "products[#{index}]", product do |up| %&gt; &lt;%= render "fields", :f =&gt; up %&gt; &lt;% end %&gt; &lt;% end %&gt; &lt;%= submit_tag "Done" %&gt; &lt;% end %&gt; </code></pre> <p>This didn't work for me, my database doesn't flag as either false or true.</p> <p>I think the problem lies in the params of the <code>"send_to_data"</code>. Unlike the <code>"purchase_date"</code> it isn't finding the object (product).</p> <pre><code>{"product"=&gt;{"purchase_date(2i)"=&gt;"12", "purchase_date(3i)"=&gt;"11", "purchase_date(1i)"=&gt;"2011"}, "send_to_data"=&gt;"1", "products"=&gt;{"0"=&gt;{"product_name"=&gt;"Test", "price"=&gt;"23", "product_store"=&gt;"13", "exact_url"=&gt;""}, "1"=&gt;{"product_name"=&gt;"", "price"=&gt;"", "product_store"=&gt;"", "exact_url"=&gt;""}, "2"=&gt;{"product_name"=&gt;"", "price"=&gt;"", "product_store"=&gt;"", "exact_url"=&gt;""}, "3"=&gt;{"product_name"=&gt;"", "price"=&gt;"", "product_store"=&gt;"", "exact_url"=&gt;""}, "4"=&gt;{"product_name"=&gt;"", "price"=&gt;"", "product_store"=&gt;"", "exact_url"=&gt;""}}, "commit"=&gt;"Done"} </code></pre> <p>Is there a way to map it to the object like the purchase date does?</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.
