How to render edit view and post flash message in rails3

Question

In my account controller I\'d like to display (render, redirect_to ?) the edit view after changes get saved and display flash notice.

 def update
    @account =         


        

Answer 1

If you just use flash[:notice] that value will still be available in the next request. Meaning, you'll see the text on the next 2 pages. Instead use flash.now to only make the value available in the current request.

format.html { 
  flash.now[:notice] = 'message'
  render :edit
}
