What is the best way for me to determine a controller variable’s value during execution?
For example, is there a way I can insert a break in the code, and cause the value of the variable to be output to the screen (or the log)?

Yes. The easiest way is to raise the value as a string. Like so:
raise @foo.to_sOr, you can install the debugger (
gem install ruby-debug), and then start the development server with the--debuggerflag. Then, in your code, call thedebuggerinstruction.Inside the debugger prompt, you have many commands, including
pto print the value of a variable.Update: here’s a bit more about ruby-debug.
