Let’s say you have three very similar methods in your Rails app:

class Clown
 def do_something_one(foo, baz)
 end

 def do_something_two(foo, baz)
 end

 def do_something_three(foo, baz)
 end
end

You also have a slew of helper methods, that call each method, and do something else with the foo & baz objects (like serialize and log them to a DB, for example).

I had googled around a while for a way to instead just have one helper method:

 def do_something_generic(which_thing = 'one', foo, baz)
    # Dynimcally call one of the three methods,
    #    based on the 'which_thing' parameter.

    # Are any Ruby mavens in da house?  Is this right? :
    c = Clown.new
    c.send 'do_something_#{which_thing}', foo, baz

 end
