Question

Answer 1

Hy i am using using this approach to show flash message.First i make partial

_flash.html.erb in shared.The code of this partial

 <% [:alert, :notice, :error].select { |type| !flash[type].blank? }.each do |type| %>
<p>
  <% if flash[:notice] %>
    <div class="alert-message error">
      <h2 style="color: #ffffff;">Notice:</h2> <br/>
      <%= flash[type] %>
    </div>
<% elsif flash[:error] %>
    <div class="alert-message error">
      <h2 style="color: #ffffff;">Errors</h2> <br/>
      <% flash[:error].each_with_index do |error, index| %>
          <%= index+1 %>. <%= error %> <br/>
      <% end %>
    </div>
  <% end %>


   </p>
  <% end %>

and i call it in application layout like this

  <div id="flash">
    <%= render :partial => 'shared/flash', :object => flash %>
  </div>

And in controller use notice,alert like this

  flash[:notice] = 'Admin was successfully created.'
  flash[:alert] = 'Admin was successfully created.'

But for showing errors i use array because it may be more than one.Like this

       def create
         @user = User.new(params[:user])
         @user.is_activated = true
# @user.skip_confirmation!
if @user.save
  role = Role.find_by_name("admin")
  RoleUser.create!(:user => @user, :role => role)
  redirect_to :controller => '/administrator', :action => 'new'
  flash[:notice] = 'Admin was successfully created.'
else
  flash[:error]=[]
  @user.errors.full_messages.each do |error|
    flash[:error] << error
  end

  render :action => "new"
end

end

add this line in application.js

   setTimeout("$('#flash').html(' ');", 10000);

Use it and enjoy!!!!!!!!!!!!!!
