    <p>I'm trying to highlight a title header or release date header every time you click on it, but i can't make it. I'm using Ruby 1.9.3 and Rails 3.2.14</p> <p>I thought it was something in my controller or view, but i don't get it. It sorts, but the yellow highlight is not applied in the header.</p> <p>Here it is my movies_controller file (just the relevant part):</p> <pre><code>class MoviesController &lt; ApplicationController ... def index @movies = Movie.find(:all, :order =&gt; params[:sort_by]) if params[:sort_by] == 'title' @title_header = 'hilite' elsif params[:sort_by] == 'release_date' @release_header ='hilite' end end ... </code></pre> <p>My view file (is HAML):</p> <pre><code>-# This file is app/views/movies/index.html.haml %h1 All Movies %table#movies %thead %tr %th{:class=&gt;@title_header, :id=&gt; "title_header"}= link_to "Movie Title", movies_path(:sort_by =&gt; 'title') %th Rating %th{:class=&gt;@release_header, :id=&gt; "release_date_header"}= link_to "Release Date", movies_path(:sort_by =&gt; 'release_date') %th More Info %tbody - @movies.each do |movie| %tr %td= movie.title %td= movie.rating %td= movie.release_date %td= link_to "More about #{movie.title}", movie_path(movie) = link_to 'Add new movie', new_movie_path </code></pre> <p>And Finally, my application.css:</p> <pre><code>html, body { margin: 0; padding: 0; background: White; color: DarkSlateGrey; font-family: Tahoma, Verdana, sans-serif; font-size: 10pt; } div#main { margin: 0; padding: 0 20px 20px; } a { background: transparent; color: maroon; text-decoration: underline; font-weight: bold; } h1 { color: maroon; font-size: 150%; font-style: italic; display: block; width: 100%; border-bottom: 1px solid DarkSlateGrey; } h1.title { margin: 0 0 1em; padding: 10px; background-color: orange; color: white; border-bottom: 4px solid gold; font-size: 2em; font-style: normal; } table#movies { margin: 10px; border-collapse: collapse; width: 100%; border-bottom: 2px solid black; } table#movies th { border: 2px solid white; font-weight: bold; background-color: wheat; } table#movies th.hilite { background-color: yellow; } table#movies th, table#movies td { padding: 4px; text-align: left; } #notice #warning { background: rosybrown; margin: 1em 0; padding: 4px; } form label { display: block; line-height: 25px; font-weight: bold; color: maroon; } </code></pre> <p>UPDATE: HTML source after rendering:</p> <pre><code>&lt;!DOCTYPE html&gt;

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.
