    <p>My rails app basically displays a dictionary of sorts, which is stored in a database. I've set up a basic rails app with scaffold to display this on a webpage, but I can't for the life of me figure out how to set this next bit up. Basically I want a row of the 26 alphabetical letters, and when you click on a letter (say 'A'), I only want to see the dictionary entries of that letter. </p> <p>My index.html.erb file:</p> <pre><code>&lt;% for char in 'A'..'Z' %&gt; &lt;%= link_to( "#{char}", "/words/lettersearch", :id =&gt; "#{char}") %&gt; &lt;% end %&gt; </code></pre> <p>my words_controller.rb file method for doing this:</p> <pre><code>def lettersearch @word = Word.find(:all, :conditions =&gt; ["word LIKE ?", "#{params[:word]}%"]) end </code></pre> <p>It then outputs the @word to another page.</p> <p>My problem is that it just outputs the entire dictionary again, no matter what letter I click on the index page. I know it's to do with the routing, as it never seems to actually run the 'lettersearch' method - it's always trying to run through the 'Show' method that's defined by default earlier in the controller.</p> <p>Anyone able to give me a quick hand with how to route this thing through? I'm pretty new to rails and I don't understand the workings of link_to very well at all.</p> <p>routes.rb:</p> <pre><code>Dictionary::Application.routes.draw do resources :words do post 'search', :on =&gt; :collection post 'lettersearch', :on =&gt; :collection end #Rest of routes.rb still commented apart from match ':controller(/:action(/:id))(.:format)' </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.
