Rails: redirect_to with :error, but flash[:error] empty

Question

I\'m trying to do a redirect while setting the flash[:error] value. (Rails 3.0.10)

In my view I have

<%= flash[:error] %>         


        

Answer 1

If you are having problem to keep the flash after redirecting to another path, then use this.

flash.keep

in your method, before redirecting.
