    <p>Using Rails 2.3.8. I wanna show data from complicated relationship.</p> <p>These are in my models:</p> <p><strong>shop.rb</strong></p> <pre><code>has_many :city_shops id | name 3 | Good Cafe </code></pre> <p><strong>city_shop.rb</strong></p> <pre><code>belongs_to :city belongs_to :shop id | city_id | shop_id | notes 2 | 4 | 3 | Delicious food in Paris </code></pre> <p><strong>city.rb</strong></p> <pre><code>belongs_to :article has_many :city_shops has_many :shops, :through =&gt; :city_shops id | article_id 4 | 5 </code></pre> <p><strong>article.rb</strong></p> <pre><code>has_many :shops, :through =&gt; :shop_articles has_many :cities, :dependent =&gt; :destroy id | user_id | name 5 | 6 | Favorite shops in France </code></pre> <p><strong>user.rb</strong></p> <pre><code>has_many :articles id | login 6 | victor </code></pre> <p>The scenario is this (may not be logical): A user with ID 6 creates many articles. Let's say he creates this article called <strong>Favorite shops in France</strong>. In this article, there are <code>cities</code>. In each <code>city</code>, there are <code>city_shops</code> where in it there are details <code>shop</code> and <code>notes</code> from <code>city_shops</code>. </p> <p>I also have individual <code>shop</code> page. I want the visitors to know what notes have been left by users, where the note is and the link to that user's article.</p> <p>In the <code>shop</code> page, it should read:</p> <p><strong>Notes by users</strong> "Delicious food in Paris" by "victor", shared in "link to favorite shops in France".</p> <p>I hope this question is clearer than previous. Thank you very much.</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.
