Given I know where a method is defined, I want to know where its called (at runtime)
Hey all, application completely breaks down in production mode. I
followed the execution file by file line by line and yet I cannot figure
out where an instance variable is being generated from. But I have a
suspicion. This method right here:
# neeeded becasuse of a rails bug
def to_s
"#{self.class.name.underscore}__#{object_id}"
end
I think it''s cause of problem. I also noticed that the developer left a
comment above it. Problem is it''s part of a class that gets yielded
into
a ruby block and there''s a number of partials that get rendered in the
new view. But I cannot find for the life of me where to_s is called
during execution of clicking a new button.
I need some debugging advice for this.
Thanks for response.

This is not a setter method. There is no argument passed to this object, and in your example, if i add one like ''skip'', of course I receive an exception "wrong number of arguments". -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

If you only want it to stop under some conditions use a global variable and test it at the offending point to find out whether to crash or not. Fred''s suggestion of using ruby-debug and putting a (possibly conditional) breakpoint there is probably better.
