    <p>Ikhthiandor: Looks like you are a beginner in the ruby/rails world. </p> <p>By running the <code>rake install</code> command, you are installing the default octopress theme using the <a href="http://en.wikibooks.org/wiki/Ruby_on_Rails/Built-In_Rails_Tools/What_is_Rake_anyway%3F" rel="nofollow">rake tool</a>. Not <code>trying to setup rake</code> as you mention in the question. </p> <p>The first error ( <code>Permission denied - source</code> when trying <code>mkdir -p source</code> - as you correctly guessed - is because the user doesn't have permissions to create that directory. </p> <p>The second error ( <code>no such file to load -- bundler/setup</code> ) is because the previous <code>install dependencies</code> steps are not performed correctly (for the user running this command). </p> <p>The install dependencies steps to be completed successfully are:</p> <pre><code>1. gem install bundler 2. rbenv rehash # If you use rbenv, rehash to be able to run the bundle command 3. bundle install </code></pre> <p>I am guessing you ran these steps successfully as 'ikhthiandor' user, so the bundler gem is not available for the 'sudo' user. </p> <p>You can fix this by either of the following options: </p> <ol> <li>changing permissions on <code>/opt/octopress</code> folder so that 'ikhthiandor' user has rights to create sub-folders/files within. </li> <li>Run all the commands in the <a href="http://octopress.org/docs/setup/" rel="nofollow">Octopress Setup doc</a> as 'sudo'</li> </ol> <p>Best practice would be to use either <a href="https://rvm.io/" rel="nofollow">rvm</a> or <a href="https://github.com/sstephenson/rbenv" rel="nofollow">rbenv</a> to manage custom installations of ruby environments per user (and not do everything as super user). </p> <p>If you are indeed a fresher in the ruby-rails world, and want to step up your knowledge of the tools and the best practices in the ruby/rails world, I suggest browsing through the first few chapters of the <a href="http://ruby.railstutorial.org/ruby-on-rails-tutorial-book" rel="nofollow">Ruby on Rails Tutorial</a> book that is available for free on-line. </p> <p>HTH</p>

    1. COYou are right. I am a beginner in ruby world. Btw, I meant to setup octopress not rake(that was a typo). According to your suggestion I made 'ikhthiandor' as the owner of /opt/octopress. It worked properly then. Thanks for taking the time to reply :) I started learning ruby from the book by Zed Shaw. I am busy with learning other core stuffs so I have planned to take ruby in small chunks. So, it will take some time to learn the basics of ruby. Once I have grasped the rvm, rbenv stuff I will redo this setup according to the best practice.

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.
