    <p>I'd like to use UUIDs in place id standard IDs in routes. This works:</p> <pre><code># UUIDs are used for ids UUID_regex = /([a-z0-9]){8}-([a-z0-9]){4}-([a-z0-9]){4}-([a-z0-9]){4}-([a-z0-9]){12}/ resources :posts, :only =&gt; [:index, :show, :create], :constraints =&gt; {:id =&gt; UUID_regex} </code></pre> <p>That is Rails accepts <code>/posts/fb0f7c67-6f9b-4e2c-a26b-7700bb9b334d</code> fine.</p> <p>When I start nesting them like this, though,</p> <pre><code># UUIDs are used for ids UUID_regex = /([a-z0-9]){8}-([a-z0-9]){4}-([a-z0-9]){4}-([a-z0-9]){4}-([a-z0-9]){12}/ resources :posts, :only =&gt; [:index, :show, :create], :constraints =&gt; {:id =&gt; UUID_regex} do resources :comments, :only =&gt; [:create, :destroy], :constraints =&gt; {:id =&gt; UUID_regex} end </code></pre> <p>Rails starts to complain: <code>No route matches [POST] "/post/fb0f7c67-6f9b-4e2c-a26b-7700bb9b334d/comments"</code></p> <p>What am I missing?</p> <p>Thx in advance.</p> <p>Notes: I'am on Rails 3.2.2 and ruby 1.9.3; <code>rake routes</code> is:</p> <pre><code>post_comments POST /posts/:post_id/comments(.:format) comments#create {:id=&gt;/([a-z0-9]){8}-([a-z0-9]){4}-([a-z0-9]){4}-([a-z0-9]){4}-([a-z0-9]){12}/, :post_id=&gt;/([a-z0-9]){8}-([a-z0-9]){4}-([a-z0-9]){4}-([a-z0-9]){4}-([a-z0-9]){12}/} post_comment DELETE /posts/:post_id/comments/:id(.:format) comments#destroy {:id=&gt;/([a-z0-9]){8}-([a-z0-9]){4}-([a-z0-9]){4}-([a-z0-9]){4}-([a-z0-9]){12}/, :post_id=&gt;/([a-z0-9]){8}-([a-z0-9]){4}-([a-z0-9]){4}-([a-z0-9]){4}-([a-z0-9]){12}/} posts GET /posts(.:format) posts#index {:id=&gt;/([a-z0-9]){8}-([a-z0-9]){4}-([a-z0-9]){4}-([a-z0-9]){4}-([a-z0-9]){12}/} POST /posts(.:format) posts#create {:id=&gt;/([a-z0-9]){8}-([a-z0-9]){4}-([a-z0-9]){4}-([a-z0-9]){4}-([a-z0-9]){12}/} post GET /posts/:id(.:format) posts#show {:id=&gt;/([a-z0-9]){8}-([a-z0-9]){4}-([a-z0-9]){4}-([a-z0-9]){4}-([a-z0-9]){12}/} </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.
