problems getting flash to display

rubyonrails-talk
1

I have a controller that looks exactly like the code below. My problem is that I can't get the flash[:notice]'s to show up on the page. Interestingly though, I when I test this controller, I have tests that make it go down both of the unhappy paths (the ActiveRecord::RecordInvalid exception and 'some_boolean_expression should've been true') and these tests pass when 'assert_match' on the flash...

assert_match(/Error saving:/, flash[:notice])

and

assert_match(/some_boolean_expression should've been true/, flash[:notice])

respectively

Any thoughts on what could possibly explain the fact I can't see the flash in the browser?

TIA...

===== controller code =====

  def do_the_action     if (some_boolean_expression)       begin         model = ModelObject.new(:attribute1 => "1", :attribute2 => "2")         model.save!                 path = "a/path" redirect_to(path) rescue ActiveRecord::RecordInvalid => error         # findme: this flash notice doesn't seem to be showing up; logging it for now         @@log.error("Error saving: #{error}")         flash[:notice] = "Error saving: #{error}"         redirect_to :action => "show"       end     else       # findme: this flash notice doesn't seem to be showing up; logging it for now       @@log.error("some_boolean_expression should've been true")       flash[:notice] = "some_boolean_expression should've been true"       redirect_to :action => "show"     end   end

Like you say, my view template has '<%= flash[:notice] %>' in it. I'm using hobo's dryml though instead of rhtml, so that may be contributing to the problem. I'll check over on their list.

Thanks...

Hopefully this will help someone else. The problem was that the first line of the 'show' action that the 'do_the_action' action was redirecting to did this:

flash[:notice] = nil

It threw me off since the flash was being picked up in the test.
