    <p>I'm attempting to edit a model's nested attributes, much as outline <a href="http://guides.rubyonrails.org/form_helpers.html" rel="nofollow">here</a>, replicated here:</p> <pre><code> &lt;%= form_for @person do |person_form| %&gt; &lt;%= person_form.text_field :name %&gt; &lt;% for address in @person.addresses %&gt; &lt;%= person_form.fields_for address, :index =&gt; address do |address_form|%&gt; &lt;%= address_form.text_field :city %&gt; &lt;% end %&gt; &lt;% end %&gt; &lt;% end %&gt; </code></pre> <p>In my code, I have the following:</p> <pre><code>&lt;%= form_for(@meal) do |f| %&gt; &lt;!-- some other stuff that's irrelevant... --&gt; &lt;% for subitem in @meal.meal_line_items %&gt; &lt;!-- # Edit 2: I need to display information here about the subitem Which I can't find a way to pass it to the partial, or work in this manner for existing items --&gt; &lt;%= subitem.food.name %&gt; &lt;%= subitem.food.calories %&gt; &lt;%= f.fields_for subitem, :index =&gt; subitem do |line_item_form| %&gt; &lt;%= line_item_form.label :servings %&gt;&lt;br/&gt; &lt;%= line_item_form.text_field :servings %&gt;&lt;br/&gt; &lt;%= line_item_form.label :food_id %&gt;&lt;br/&gt; &lt;%= line_item_form.text_field :food_id %&gt;&lt;br/&gt; &lt;% end %&gt; &lt;% end %&gt; &lt;%= f.submit %&gt; &lt;% end %&gt; </code></pre> <p>This works great, except, when I look at the HTML, it's creating the inputs that look like the following, failing to input the correct id and instead placing the memory representation(?) of the model. As a result, an update fails:</p> <pre><code>&lt;input type="text" value="2" size="30" name="meal[meal_line_item][#&lt;MealLineItem:0x00000005c5d618&gt;][servings]" id="meal_meal_line_item_#&lt;MealLineItem:0x00000005c5d618&gt;_servings"&gt; </code></pre> <p><strong>EDIT:</strong> The reason I'm attempting to do it in this method is that I need to gather some information on associations for existing meal_line_items. For example, in the area where I took out code, I have some code to the effect of:</p> <pre><code>&lt;%= subitem.food.name %&gt; &lt;%= subitem.food.calories %&gt; </code></pre> <p>Getting this information won't work if I am using a form builder with partials, at least, not in my trials.</p> <p><strong>Edit 2:*</strong> See the edit in the code. Here's my MealLineItem</p> <pre><code>class MealLineItem &lt; ActiveRecord::Base # Associations --------------------- belongs_to :food belongs_to :meal end </code></pre> <p>And meal accepts_nested_attributes for the model. As you can see it belongs to both food and meal model. For the existing meal_line_item I need to do something like:</p> <pre><code>meal_line_item.food.name </code></pre>

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.
