    <p>I'm using jeweler to create a gem for Rails 3. The gem contains a rake task and one of the things it does is wiping the DB, so I'm using 'database_cleaner'.</p> <p>I'm specifying the gem dependency inside the gem's Gemfile</p> <pre><code>gem 'database_cleaner' </code></pre> <p>And in the Rakefile</p> <pre><code>Jeweler::Tasks.new do |gem| ... gem.add_dependency 'database_cleaner' end </code></pre> <p>Then inside lib I've created the files my_gem.rb and tasks.rake. As follows, my_gem.rb:</p> <pre><code>module MyGem class Railtie &lt; Rails::Railtie rake_tasks do load 'tasks.rake' end end end </code></pre> <p>And tasks.rake:</p> <pre><code>task :my_task do DatabaseCleaner.strategy = :truncation DatabaseCleaner.clean end </code></pre> <p>I installed the gem (sudo rake install), created an empty rails project and added the gem dependency in the rails' Gemspec (<code>gem 'my_gem'</code>). But when I try to run <code>rake my_task</code> I get the error <code>uninitialized constant DatabaseCleaner</code>.</p> <p>I've also tried adding <code>require 'database_cleaner'</code> from inside the task, which raises the error <code>no such file to load -- database_cleaner</code> and <code>gem 'database_cleaner'</code> that raises the error <code>database_cleaner is not part of the bundle. Add it to Gemfile.</code>.</p> <p>Is there a way to solve this without adding <code>gem 'database_cleaner'</code> to the rails project's Gemspec?</p> <p>Thanks</p> <p>UPDATE (adding the link to the source code): <a href="https://github.com/jordinl/dummy_tasks" rel="noreferrer">https://github.com/jordinl/dummy_tasks</a></p>

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.
