    Upgrading JotRod to Rails 3.1.3

    When preparing to add some layout features to JotRod, I realized it was a Rails 3.0.9 application. Here's a quick rundown on upgrading to Rails 3.1.3. Download 164.7 MB Download (iPod & iPhone) 37.9 MB Take the 2011 Readers Survey

    Followers and Following

    In order to get someone a timeline in JotRod, we need followers and following lists to compile the Jots from. This means that we need to add a new ColumnFamily called Followers and another one called Following. We don't have the joins capability from relational databases to do this for us. I'm going to hijack the User model's database connection to create the ColumnFamilies. (We don't have migrations, yet.) Here's what I ran in the rails console: cf_def = CassandraThrift::CfDef.new(:keyspace => "JotRod", :name => "Followers") User.connection.add_column_family(cf_def) cf_def = CassandraThrift::CfDef.new(:keyspace => "JotRod", :name => "Following") User.connection.add_column_family(cf_def) Now that we have the ColumnFamilies, I want to have syntax like this to define the relationships on the User model: list :followers, :User list :following, :User This should provide the following API: #followers - returns an array of users as specified from the Followers ColumnFamily #followers(user)  - adds the user to the User object's followers list if it's not already there and a similar API for following.

    ActiveModel Callbacks

    In the Jots (like tweets) in JotRod, I needed to generate a hash on creation as the key for the Jots. So, I determined that the easiest way to do that was to include ActiveModel Callbacks. The module is pretty simple to add to your classes. Here's a demo of how to add it to Sandra.

    Introduction to Sandra: The Cassandra ORM

    When I started playing with Cassandra, I wound up writing part of an ORM to get what I needed from it. I want to build actual projects with Rails, Ruby, or other technologies for my videos rather than just narrowly demonstrate a piece of technology. So, I'm bringing you up to speed with Sandra so that as I continue with the Twitter Clone, you'll know what I'm using and why I'm adding things to it.

    Ruby Koans

    I’m working on another Cassandra demo, but didn’t have time to finish, so I decided to show you Ruby Koans. It’s a very interesting test-driven approach to learning Ruby. I hope you enjoy it. Download 52.5 MB Download (iPod & iPhone) 31.1 MB Take the 2011 Readers Survey

    Cassandra Basic Schema and Ruby Gem

    You can get cassandra at cassandra.apache.org and the ruby gem by running: gem install cassandra I did run into a problem with the trift_client gem when installing. If you get a Load Error, run this. sudo chmod 644 /usr/local/lib/ruby/gems/1.8/gems/thrift_client-0.6.3/lib/thrift_client/*.rb sudo chmod 755 /usr/local/lib/ruby/gems/1.8/gems/thrift_client-0.6.3/lib/thrift_client/connection Here are some of the Cassandra commands from the video: #connects to the cassandra server using the Twitter keyspace store = Cassandra.new(“Twitter”) # create a new column family in the Twitter keyspace called Users cf_def = CassandraThrift::CfDef.new(:keyspace => “Twitter”, :name => “Users”) store.add_column_family(cf_def) # add or create a row to the column family store.insert(“Users”, “cmaxw”, {“name” => “Charles Max Wood”, “description” => “Awesome coder”}) # remove a column from a row store.remove(“Users”, “cmaxw”, “description”) Download 17.2 MB Download (iPod & iPhone) 20.9 MB Take the 2011 Readers Survey
