    <p>I've been struggling with this for a few days now - I added bootstrap (and some other gems) to my rails app, but for some reason the appropriate CSS files are not rendering and thus the bootstrap styles are not showing up.</p> <p>Here are the relevant parts of my files:</p> <p><code>application.html.erb</code> in <code>app/views/layouts</code>:</p> <pre><code>&lt;head&gt; &lt;title&gt;Myapp&lt;/title&gt; &lt;%= stylesheet_link_tag "application", :media =&gt; "all" %&gt; &lt;%= javascript_include_tag "application" %&gt; &lt;%= csrf_meta_tags %&gt; &lt;script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"&gt;&lt;/script&gt; &lt;script type="text/javascript" src="https://raw.github.com/twitter/bootstrap/master/js/bootstrap-dropdown.js"&gt;&lt;/script&gt; &lt;/head&gt; </code></pre> <p><code>application.css</code> in <code>app/assets/stylesheets</code>:</p> <pre><code>/* * This is a manifest file that'll be compiled into application.css, which will include all the files * listed below. * * Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets, * or vendor/assets/stylesheets of plugins, if any, can be referenced here using a relative path. * * You're free to add application-wide styles to this file and they'll appear at the top of the * compiled file, but it's generally better to create a new file per style scope. * *= require_self *= require_tree . */ </code></pre> <p>(There are also plenty more CSS files in this folder, including <code>bootstrap_and_overrides.css</code> and <code>gmaps4rails.css</code>).</p> <p>And the server log when I load the page:</p> <pre><code>$ rails server =&gt; Booting WEBrick =&gt; Rails 3.2.8 application starting in development on http://0.0.0.0:3000 =&gt; Call with -d to detach =&gt; Ctrl-C to shutdown server SECURITY WARNING: No secret option provided to Rack::Session::Cookie.

My <code>RAILS_ENV</code> is <code>development</code>. As I understand, rails should be compiling and serving all of the CSS files including <code>boostrap_and_overrides.css.scss</code> because of the <code>require_tree .</code> call. I've run <code>rake assets:precompile</code> and <code>bundle exec rake assets:precompile</code> multiple times, but I don't think that should matter. Im running ruby 2.0.0p0 (2013-02-24 revision 39474).</p> <p>The REALLY weird thing is that me and my partners on this project have the exact same code (from our github repository), and it works on their local machines but it doen't work on mine. Does anyone have any input at all into what's going on?</p>

    1. COcorrect, you don't need assets precompile in development(in fact, you might want to remove all files in /public/assets). Can you see the content of the css from source view in Chrome?I had similar problem before where the css links are there but they all empty.

    2. CONo, the CSS file that gets rendered in Chrome is empty (which is weird, since it should at least include the `require` comments etc). For what it's worth, the MD5'd file in `public/assets` specified in `manifest.yml` is also empty (but that shouldn't matter in development, right?) It occurred to me that things might be working for everyone else on my team but not for me because they might have `RAILS_ENV=production`, but I've tried setting mine to production as well, but nothing is configured to serve the assets, so I don't think that's the problem.

    3. COcan you post up your development.rb in config/environments(you said it's not different from others?). I got this error once in production but it was a wrong unicorn setup(not rails issues). It's your local issue for sure.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
