    <p>I'm developing a Rails app on a Mac, and I'm new to testing, so I just added these gems to my <strong>Gemfile</strong>:</p> <pre><code>group :test, :development do gem 'rspec-rails' gem 'rb-fsevent' gem 'growl' end </code></pre> <p>But my production server runs Linux, so even if they aren't grouped in <code>:production</code>, bundler (<em>v1.0.21</em>) still attempts to install them. ...and fails, obviously!<br> <code>extconf.rb:19:in '&lt;main&gt;': Only Darwin (Mac OS X) systems are supported (RuntimeError)</code></p> <p>Setting <code>RAILS_ENV</code> to production before running <code>bundle install</code> <em>doesn't work</em>.</p> <p>It worked by running <code>bundle install --without development test</code>, but how can these gems be taken into consideration by bundler only based on your OS?</p> <hr> <p><strong>Edit:</strong> The bundler wiki provides details on how to <a href="https://github.com/carlhuda/bundler/wiki/Platform-as-a-parameter">use platform as a parameter</a>.<br> The same solution is given in <a href="https://github.com/carlhuda/bundler/issues/663">bundler issue #663</a>, so I tried:</p> <pre><code>group :test, :development do gem 'rspec-rails' platforms :darwin do gem 'rb-fsevent' gem 'growl' end end </code></pre> <p><code>bundle install</code> does not work, but even if we go back to square one and do<br> <code>bundle install --without darwin</code>, the result is <code>'darwin' is not a valid platform.<br> The available options are: [:ruby, :ruby_18, :ruby_19, :mri, :mri_18, :mri_19, :rbx, :jruby, :mswin, :mingw, :mingw_18, :mingw_19]</code></p> <hr> <p>Any other (elegant) approaches?</p>

    1. COBut what about platform independency? I hope you still keep in mind this aspect of Rails.

    2. CO@MichałCzapko Platform independency is still there for this particular case because there are equivalents for `rb-fsevent`

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.
