    <p>I've found a few posts about this but nothing that I've tried to work with has done it for me so far. I'm still pretty fresh to rails - I'm basically solid with HTML and CSS, but I took the Skillshare Rails class and I'm working on combining that with the Railstutorial book. So please be gentle.</p> <p>I have a basic app, with users that can create 'items.' I used scaffolding to get 'items' up. They might as well be microposts. But with the views that scaffolding creates, I wanted to display the email address of the user instead of the email address. What would I change in the model, view, and controller? Here's what I've got.</p> <p>controller:</p> <pre><code>def email @email = @item.user_id.email end </code></pre> <p>view:</p> <pre><code>&lt;td&gt;&lt;%= item.content %&gt;&lt;/td&gt; &lt;td&gt;&lt;%= @email %&gt;&lt;/td&gt; &lt;td&gt;&lt;%= link_to 'Show', item %&gt;&lt;/td&gt; &lt;td&gt;&lt;%= link_to 'Edit', edit_item_path(item) %&gt;&lt;/td&gt; &lt;td&gt;&lt;%= link_to 'Destroy', item, confirm: 'Are you sure?', method: :delete %&gt;&lt;/td&gt; </code></pre> <p>item model:</p> <pre><code>class Item &lt; ActiveRecord::Base attr_accessible :content, :user_id validates :content, :length =&gt; { :maximum =&gt; 140 } belongs_to :user end </code></pre> <p>user model:</p> <pre><code>class User &lt; ActiveRecord::Base # Include default devise modules. Others available are: # :token_authenticatable, :confirmable, # :lockable, :timeoutable and :omniauthable devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :validatable # Setup accessible (or protected) attributes for your model attr_accessible :email, :password, :password_confirmation, :remember_me has_many :items end </code></pre>

    1. COI think you want `@email = @item.user.email` since you cant get the email of `user_id`

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.
