Question

How do you conditionally execute something when overwriting super, while still returning the result of super? I am sure there is a cleaner way of writing this in Ruby

def my_method
  result = super
  if result.success?
    my_other_method1
    my_other_method2
    if @my_field
      @x = @y
    end
  end

  result
end

I believe something can be done with block, but don’t really understand them yet. Any pointers would be greatly appreciated.

If you’re using ruby 1.9, you could use the Object#tap method to clean that up a bit.

def my_method
    super.tap do |result|
        if result.success?
            my_other_method1
            my_other_method2
            if @my_field
                @x = @y
            end
        end
    end
end
