Unfortunately it will never work the way you want it to.
Place this code into an initializer file (under the initializers
folder) or place it under the "lib" folder and do an explicit require.
Also, if all you want to do is to add a method to a class defined
elsewhere, do it like this:
Jason::MyClass.class_eval do
def another_method
# do whatever you want to do here.
end
end
