This means that you can break out of execution at any point 105 in the code, investigate and change the model, AND then resume execution! Example: 103 With debugger, you can break out of execution at any point in the application, examine objects, 104 step through the code, change things like values of variables, and resume execution. To use 105 debugger, you need to install the ruby-debug gem (simply run: <tt>gem install ruby-debug</tt>). Put 106 <tt>debugger</tt> in your code where you want to stop the execution and begin to use debugger. You 107 will also need to start your Mongrel or WEBrick server with --debugger or -u option (E.g. 108 <tt>script/server -u</tt>). Here's an example: 106 109 107 110 class WeblogController < ActionController::Base 108 111 def index … … 111 114 end 112 115 end 113 116 114 So the controller will accept the action, run the first line, then present you 115 with a IRB promptin the server window.
