==== Notes None so far == Deployment TODO Notes * chmod 666 log/production.log * chmod 777 public/ckeditor_assets -R == Recommended Platform/Stack Ruby Interpreter: REE (Ruby Enterprise Edition) Framework: Rails 3.0.0 App: Phusion Passenger Web: Apache 2.2.8 (built from source) (http://www.rubyenterpriseedition.com/comparisons.html#participants) (http://www.engineyard.com/products/technology/stack) == Resources Updating Jquery and Rails.js: 'rails generate jquery:install #--ui to enable jQuery UI --version to install specific version' == Git Help http://progit.org/book/ == Basic Rails http://guides.rails.info/index.html == Debugging Rails First area to check is the application log files. Have "tail -f" commands running on the server.log and development.log. Rails will automatically display debugging and runtime information to these files. Debugging info will also be shown in the browser on requests from 127.0.0.1. You can also log your own messages directly into the log file from your code using the Ruby logger class from inside your controllers. Example: class WeblogController < ActionController::Base def destroy @weblog = Weblog.find(params[:id]) @weblog.destroy logger.info("#{Time.now} Destroyed Weblog ID ##{@weblog.id}!") end end The result will be a message in your log file along the lines of: Mon Oct 08 14:22:29 +1000 2007 Destroyed Weblog ID #1! More information on how to use the logger is at http://www.ruby-doc.org/core/ == Debugger Debugger support is available through the debugger command when you start your WEBrick server with --debugger. This means that you can break out of execution at any point in the code, investigate and change the model, and then, resume execution! You need to install ruby-debug to run the server in debugging mode. With gems, use <tt>sudo gem install ruby-debug</tt>. Example: class WeblogController < ActionController::Base def index @posts = Post.find(:all) debugger end end So the controller will accept the action, run the first line, then present you with a IRB prompt in the server window. Here you can do things like: >> @posts.inspect => "[#<Post:0x14a6be8 @attributes={"title"=>nil, "body"=>nil, "id"=>"1"}>, #<Post:0x14a6620 @attributes={"title"=>"Rails", "body"=>"Only ten..", "id"=>"2"}>]" >> @posts.first.title = "hello from a debugger" => "hello from a debugger" ...and even better, you can examine how your runtime objects actually work: >> f = @posts.first => #<Post:0x13630c4 @attributes={"title"=>nil, "body"=>nil, "id"=>"1"}> >> f. Display all 152 possibilities? (y or n) Finally, when you're ready to resume execution, you can enter "cont". == Console The console is a Ruby shell, which allows you to interact with your application's domain model. Here you'll have all parts of the application configured, just like it is when the application is running. You can inspect domain models, change values, and save to the database. Starting the script without arguments will launch it in the development environment. To start the console, run <tt>rails console</tt> from the application directory. Options: * Passing the <tt>-s, --sandbox</tt> argument will rollback any modifications made to the database. * Passing an environment name as an argument will load the corresponding environment. Example: <tt>rails console production</tt>. To reload your controllers and models after launching the console run <tt>reload!</tt> link:http://www.rubycentral.com/pickaxe/irb.html == dbconsole You can go to the command line of your database directly through <tt>rails dbconsole</tt>. You would be connected to the database with the credentials defined in database.yml. Starting the script without arguments will connect you to the development database. Passing an argument will connect you to a different database, like <tt>rails dbconsole production</tt>. Currently works for MySQL, PostgreSQL and SQLite 3.
