如何从动作内部调用视图上的渲染？

Question

I want to get the rendered response from the action BEFORE it returns, so something like:

def test

  my_html = # RENDER VIEW HERE AND ASSIGN TO VARIABLE


  render :text => my_html

end

How can I do this?

Answer 1

You could use render_to_string

def test
  my_html = render_to_string(:action => :show)

  render :text => my_html
end

render_to_string accepts all options that render does.
