flash[:notice] not working in Rails

Question

I have the following snippet of code in my controller

  def create
    @message = Message.new(params[:message])
    @message.message = h(@message.message)
    if @message.save
       flash[:message] = "Message Sent. Thank You for Contacting Me"
    else
       flash[:message] = "OOps Something went wrong"
    end
    redirect_to :action => 'contact'
  end

When I try to display the flash message in the contact form it doesnot display. I looked up possible solutions, but they dont seem to work. Any ideas what is going wrong?

Answer 1

The flash hash can contain any set of messages you want to save until the next render. Scaffolds usually use the contents of flash[:notice] for notification messages. If you didn't use a scaffold to generate your web page you will have to add <%= flash[:notice]%> to your views.

You're setting flash[:message] in your controller. So it's not going to show up anywhere in your view unless your view contains <%= flash[:message]%> somewhere.

Your possible solutions are change all occurrences of flash[:message] to flash[:notice] in your controller or add <%= flash[:message]%> to any views that this action could render.

Answer 2

Not saying that you wouldn't have tried it, but if I were you I would do something down the lines like

<% if flash[:messsage].blank? %>
  <h1> flash hash is blank </h1>
<% end %>

If you see the "flash hash is blank" in your browser you know what it means.

EDIT:-

Something from the docs "Just remember: They‘ll be gone by the time the next action has been performed." Try this in your controller

flash.keep(:message) #keep the flash entry available for the next action

Answer 3

Your controller is redirecting to :action => 'contact'. Ensure that the template being rendered for that action has the flash notice output.

<%= flash[:message] %>

Also, you may want to use render :action ... vs redirect_to :action .... Save yourself a request.
