    <p>I am trying to install track, a ruby on rails application on ubuntu 10.04. Bundle install works fine, however when I run rake db:migrate I get some deprecation warnings, and then an error claiming that system "Could not find mongrel" despite the fact that it is installed. If I list the gems mongrel is clearly on the list, but when running rake commands I get this error. Any ideas?</p> <pre><code>Could not find mongrel (~&gt; 1.1.5) amongst [rake-0.9.2.2, RedCloth-4.2.8, ZenTest-4.6.1, aasm-2.2.0, activesupport-2.3.14, rack-1.1.0, actionpack-2.3.14, actionmailer-2.3.14, activerecord-2.3.14, activeresource-2.3.14, acts_as_list-0.1.4, archive-tar-minitar-0.5.2, bcrypt-ruby-2.1.4, builder-3.0.0, bundler-1.0.18, columnize-0.3.4, diff-lcs-1.1.2, json-1.5.3, gherkin-2.4.11, term-ansicolor-1.0.6, cucumber-1.0.2, cucumber-rails-0.3.2, daemons-1.0.10, database_cleaner-0.6.7, flexmock-0.9.0, gem_plugin-0.2.3, has_many_polymorphs-2.13, highline-1.5.2, hoe-2.12.0, hpricot-0.8.4, htmlentities-4.3.0, i18n-0.6.0, ruby_core_source-0.1.5, linecache19-0.5.12, mime-types-1.16, polyglot-0.3.2, treetop-1.4.10, mail-2.3.0, memory_test_fix-0.1.3, mongrel-1.2.0.pre2, nokogiri-1.4.7, rack-test-0.6.1, rails-2.3.14, rspec-1.3.2, rspec-rails-1.3.4, ruby-debug-base19-0.11.25, ruby-debug19-0.11.6, ruby-openid-2.1.8, rubycas-client-2.2.1, rubyjedi-actionwebservice-2.3.5.20100714122544, sanitize-1.2.1, selenium-client-1.2.18, soap4r-ruby1.9-2.0.3, sqlite3-1.3.4, test-unit-1.2.3, thoughtbot-factory_girl-1.2.2, webrat-0.7.3, will_paginate-2.3.16, yard-0.7.3] </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.
