And return at the end of the method

Question

Sometimes I see this code:

def bar
  #......
  if response && response.body
    #......
    render(:text => html) and return
  end
end

I wonder if it makes sense to use and returnat the very end of the method?

Answer 1

I saw such code just not at the bottom of the method (this makes sense because the render is not the end of the method). But here I do not see the point.

See Avoid Double Render Mistakes .

Answer 3

, render, render , : Render and/or redirect were called multiple times in this action

, - , , :

def bar
  ...
  x = true
  ...
  if x
   render(:text => html)
  end

  ...
  render(:text => html)
end
