ruby: do nothing (dummy) function

Question

When working with ruby on rails code, what is the conventional way (or most elegant way) to let rails do nothing? For example when debugging and commenting out a line where there has to be a statement:

begin
  #some_commented_out_function
rescue => e
[...]
end

Is there a dummy function I quickly can put in instead of the commented out line? What is the convention for this?

Answer 1

Ruby doesn't have a pass or no-op statement. In your example, that code would work as written, with or without a comment.

If you'd like to make it explicit, a line with just nil or a comment explaining the method would probably be considered conventional.
