    <p>I'm working through Michael Hartl's Ruby on Rails tutorial on <a href="http://ruby.railstutorial.org" rel="nofollow noreferrer">http://ruby.railstutorial.org</a>. I'm having trouble with Chapter 11, specifically when attempting to delete a micropost. </p> <p>I'm having the same problem as this user <a href="https://stackoverflow.com/questions/5871875/no-route-matches-error-on-delete-of-micropost-in-chapter-11-of-hartls-ruby-on">Routing Error No route matches [GET] "/microposts/304"</a>. He was able to solve the problem by commenting out the jQuery gem and it worked. I, however, wasn't as lucky. </p> <p>Here is my current Gemfile:</p> <pre><code>source 'http://rubygems.org' gem 'rails', '3.1.1' # Bundle edge Rails instead: # gem 'rails', :git =&gt; 'git://github.com/rails/rails.git' gem 'sqlite3' gem 'gravatar_image_tag', '1.0.0.pre2' gem 'will_paginate', '3.0.pre2' gem 'jquery-rails' gem 'pg' group :development do gem 'faker', '0.3.1' end # Gems used only for assets and not required # in production environments by default. #group :assets do # gem 'sass-rails', '~&gt; 3.1.4' # gem 'coffee-rails', '~&gt; 3.1.1' # gem 'uglifier', '&gt;= 1.0.3' #end # To use ActiveModel has_secure_password # gem 'bcrypt-ruby', '~&gt; 3.0.0' # Use unicorn as the web server # gem 'unicorn' # Deploy with Capistrano # gem 'capistrano' # To use debugger # gem 'ruby-debug19', :require =&gt; 'ruby-debug' group :test do # Pretty printed test output gem 'turn', :require =&gt; false end </code></pre> <p>=> A quick side-note: An error <a href="https://stackoverflow.com/questions/8047651/no-javascript-runtime-on-windows-when-running-rails-server">No Javascript runtime on windows when running rails server</a> kept arising when I ran the <code>rails server</code> command but once I commented out the <code>'sass-rails'</code>, <code>'coffee-rails'</code>, and <code>'uglifier'</code> gems it would run successfully. I'm using a Windows PC and was told that this might be a specific problem to Windows machines.</p> <p>Also, here is the current outcome of my <code>bundle install</code> command:</p> <pre><code>Using rake (0.9.2.2) Using multi_json (1.0.3) Using activesupport (3.1.1) Using builder (3.0.0) Using i18n (0.6.0) Using activemodel (3.1.1) Using erubis (2.7.0) Using rack (1.3.5) Using rack-cache (1.1) Using rack-mount (0.8.3) Using rack-test (0.6.1) Using hike (1.2.1) Using tilt (1.3.3) Using sprockets (2.0.3) Using actionpack (3.1.1) Using mime-types (1.17.2) Using polyglot (0.3.3) Using treetop (1.4.10) Using mail (2.3.0) Using actionmailer (3.1.1) Using arel (2.2.1) Using tzinfo (0.3.31) Using activerecord (3.1.1) Using activeresource (3.1.1) Using ansi (1.4.1) Using bundler (1.0.21) Using faker (0.3.1) Using gravatar_image_tag (1.0.0.pre2) Using rack-ssl (1.3.2) Using json (1.6.1) Using rdoc (3.11) Using thor (0.14.6) Using railties (3.1.1) Using jquery-rails (1.0.17) Using pg (0.11.0) Using rails (3.1.1) Using sqlite3 (1.3.4) Using turn (0.8.3) Using will_paginate (3.0.pre2) Your bundle is complete!

    3. CO@sarnold: I was using rake 0.9.2 and running `rake routes` didn't work. So, I followed this <http://stackoverflow.com/questions/6085610/ruby-on-rails-and-rake-problems-uninitialized-constant-rakedsl> example and switched to rake 0.8.7 and `rake routes` worked. I appended it to the question.

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.
