I have a specific application helper do display all my flash messages
( according to my css )
def flash_messages
result =""
%w(notice warning error alert).each do |msg|
# change skin labels
box = "info_box" if msg == "notice"
box = "tip_box" if msg == "warning"
box = "error_box" if msg == "error"
box = "error_box" if msg == "alert"
result << content_tag(:div, content_tag(:p,
flash.now[msg.to_sym]), :class => "#{box}") unless
flash[msg.to_sym].nil?
end
result.html_safe
end
and I use <%= flash_messages %> to display the flash[:error] when
rendering again the :new action
this is working fine,.. however in the form , I have a link to go back
to the :index page
upon the index page display , the flash[:error] is not cleared.. ( it
will if I add flash[:error] = nil? in my index action before
rendering...
I thought that : flash.now[msg.to_sym]) would be enough .. but seems
not to be the case
any clue ? thanks

In your controllers, make sure that you''re using flash.now if you''re rendering a template and flash if redirecting. So I think you have something like flash[:error] = ''Error!'' render :new in your controller. Change flash to flash.now and it should work.> -- > You received this message because you are subscribed to the Google Groups > "Ruby on Rails: Talk" group. > To post to this group, send email to rubyonrails-talk-/JYPxA39Uh5TLH3MbocFF+G/Ez6ZCGd0@public.gmane.org > To unsubscribe from this group, send email to > rubyonrails-talk+unsubscribe-/JYPxA39Uh5TLH3MbocFF+G/Ez6ZCGd0@public.gmane.org > For more options, visit this group at > http://groups.google.com/group/rubyonrails-talk?hl=en. > >-- ------------------------------------------------------------- visit my blog at http://jimlabs.heroku.com -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
