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

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.

Hi Gautam,

Please check your routes.rb first, I think u forget to specify the name  
of the action in route.

try this out. Change

map.connect ‘/notices/:id/:abc’, :controller =\> “notices”, :action

> =\> “abc”

to

map.abc\_notice ‘/notices/:id/:abc’, :controller =\> “notices”, :action

> =\> “abc”

Then when you call abc\_notice\_path(4, ‘alphabet’)

Maybe that will help out.

Here is the code of my routes.rb file  
Please suggest corrections, if any…

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’
