When users sign up to my application I have a welcome message appear on

  • 0

When users sign up to my application I have a welcome message appear on the home page using Devise’s sign_in_count column. 

def home
 if current_user.sign_in_count == 1 
  flash.now[:notice] = "Welcome!"
 end
end

The only problem though is it stays there until they sign out and sign back in. How can I make it show only once and disappear when the page is refreshed or changed? Is there some rails way to do this?

Thank you.

EDIT

application.html.erb

<body>
 <div class="container">
   <%= render "shared/flash_message" %>
    <%= yield %>
 </div>
</body>

_flash_message.html.erb

<% [:notice, :error, :alert].each do |level| %>
 <% unless flash[level].blank? %>
  <div class="span12">
   <div class="<%= flash_class(level) %> fade in">
    <a href="#" data-dismiss="alert" class="close">×</a>
     <%= content_tag :p, flash[level] %>
   </div>
  </div>
 <% end %>
<% end %>

    In your layouts/application.html.erb you should have something like this:

    <% flash.each do |key,  value| %>
<%= content_tag(:div, value, class: "flash #{key}") %>
<% end %>

    Doing this way, should works as you expect.

    EDIT

    What if you verify for the current_user is already set?

    def home
 if current_user && current_user.sign_in_count == 1 
  flash.now[:notice] = "Welcome!"
 end
end

    OK! Got it! The sign_in_count column from Devise will remain the same until the next login, so, it will always keep showing you the Welcome! message. To make this work as you expect you have to create a flag on it.

    def home
 if current_user && current_user.sign_in_count == 1
  unless session[:display_welcome]
    flash.now[:notice] = "Welcome!"
    session[:display_welcome] = true
  end
 end
end

    You can try using session or cookies.
