undefined method `abc_notice_path' for #<ActionView::Base:0xed65220>

Please help me in solving an issue.
I wonder why i am getting this error. This method is defined in a
controller which was generated through scaffolding and other functions
that were created are working fine.
Please help me. I am a novice to rails. Any help will be highly
appreciated.

I am getting the following error when trying to link a method in a
view so that it can be called on that very object(id).

undefined method `abc_notice_path' for #<ActionView::Base:0xed65220>

Extracted source (around line #25):

22: <%= link_to 'Edit', edit_notice_path(@notice) %> |
23: <%= link_to 'Back', notices_path %>
24: |
25: <%= link_to 'Save', abc_notice_path(@notice) %>

Here is the code for my method.

def abc
     @notice = Notice.find(params[:id])
     #f = File.new("#{RAILS_ROOT}/public/jar/notice.txt","w")
    #f.write @notice.title
    #f.write @notice.body
    #f.write @notice.user_name
    #f.close
    #send_file("#{RAILS_ROOT}/public/jar/notice.txt")
  end

The *_path helpers are created for you from your config/routes.rb
file. Have you added abc as a member action on the notices
collection ?

Thanks for your kind reply.
Here is the code of my routes.rb file
Please suggest corrections, if any...

   map.resources :notices
   map.resources :users, :has_many => :notices
   map.resource :session

  map.connect ':controller/:action/:id'
  map.connect ':controller/:action/:id.:format'
  map.connect '/notices/:id/:abc', :controller => "notices", :action
=> "abc"

  map.root :controller=> 'welcome'
  map.signup '/signup', :controller => 'users', :action => 'new'
  map.login '/login', :controller => 'sessions', :action => 'new'
  map.logout '/logout', :controller => 'sessions', :action =>
'destroy'
  map.create '/create', :controller => 'notices', :action => 'new'
