    <p>I will give an example.</p> <p>Say I have Category and Product as my two models and another ChosenProduct that specifies/handles the many to many relationship between them. Now when I have certain categories and I am iterating in a loop on these categories getting the corresponding products. How to access these multiple product objects in my view? </p> <p>I am new to Rails and MVC so for now I am doing this task in my view itself. But I think this shouldn't be the right way. How should I approach this ?</p> <p>I am adding my view code as asked. This works for me fine now. But I don't think its pretty.</p> <pre><code> &lt;ul&gt; &lt;% @categories.each do |category| %&gt; &lt;li&gt; &lt;%= image_submit_tag("add.png", :height =&gt; "20", :width =&gt; '20', :name=&gt;"add_product_to_#{category.id}", :id=&gt;"add_product_to_#{category.id}" ) %&gt; &lt;%= category.category_name %&gt; &lt;% @chosen_products = category.chosen_products %&gt; &lt;% @chosen_products.each do |chosen_product| %&gt; &lt;% @products = Product.where(:id =&gt; chosen_product.product_id).all %&gt; &lt;% @products.each do |product| %&gt; &lt;ul&gt; &lt;li&gt;&lt;%= product.product_name %&gt; &lt;ul&gt; &lt;li&gt;&lt;%= image_tag("#{product.product_image_url}", :size =&gt; "200x200", :alt =&gt; "Can not load image!") %&gt;&lt;/li&gt; &lt;li&gt;&lt;%= product.product_image_url %&gt;&lt;/li&gt; &lt;/ul&gt; &lt;/li&gt; &lt;/ul&gt; &lt;% end %&gt; &lt;% end %&gt; &lt;% end %&gt; &lt;/li&gt; &lt;/ul&gt; </code></pre>

    2. COMarshal your data in the controller and let the view code do all the iterating necessary. Ideally (and this is a matter of opinion, you will find proponents on both sides), your view code does not do any database reading. I.e., no Product.find() or Product.where(). If you find yourself itching to make those sorts of calls, you probably want an ajax solution.

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.
