hi @ all

I create a new archiv.html.erb and a archiv method in the controller.  
Now, I would like to link from index.html.erb to archiv.html.erb. I  
tried to use \<%= link\_to ‘archive’, archiv\_xxx\_path %\> but it doesn’t  
run.  
It appears a error message “SyntaxError in xxx#index”.

Does anyone know, how I can enhance this problem?

thanks a lot…

Hi,  
You can use \<%= link\_to ‘archive’, :action =\> ‘archive’ %\> in the view.

Then define an action in your controller. To do this, all you need is:  
def archive  
end  
This will automatically go to a page titled “archive” in your  
controller’s view, ex: archive.rhtml

Good luck,

- Jeff

I’ve do this but it appears the error:  
"ActiveRecord::RecordNotFound in xxxController#show  
Couldn’t find xxx with ID=archiv "

It seems like a routing problem, isn’t it?

That I’m not so sure on… Is your action defined in a different  
controller? If so, you can use:  
\<%= link\_to ‘action’, :controller =\> ‘ControllerName’, :action =\>  
‘ActionName’ %\>

Hope it helps… Other than that, I don’t know what that error is…

hmmm… I’m pretty new at RoR, so I’m not sure about this, but have you  
tried naming it something other than “archive”? Perhaps it is a built-in  
method or class or something that is throwing off your statement. Try  
“archive\_data” or something.

No, both methods are in the same controller - so I don’t need the  
:controller statement.

In the new version of rails (2.0), I can use for example \<%= link\_to  
‘show’, show\_xxx\_path %\>. Why can’t I use the same principle with the  
archive? I want to use \<%= link\_to ‘archive’, archiv\_xxx\_path %\> but it  
doesn’t run!

Hi K. R.,

The record not found error is due to the RESTful interpretation of  
URLs by Rails. Given the URL …

[http://localhost:3000/xxx/archive](http://localhost:3000/xxx/archive)

… Rails rails assumes that you are calling the ‘show’ action on the  
‘xxx’ controller with ‘archiv’ as the ID of the model instance to be  
shown.

To get rails to understand that ‘archiv’ is a new action, you need to  
edit the routes.rb file and add appropriate routes using either  
the :collection option (if the archiv action works with a collection  
of model instances) or with the :member option (if you are working  
with only one instance of the model).

Check out the screencasts below for a quick intro to routes and custom  
actions

sorry, but it isn’t a problem with the naming convention. When I put an  
id behind the url, then the application runs. For example:  
[http://localhost:3000/xxx/archive/1](http://localhost:3000/xxx/archive/1) but with  
[http://localhost:3000/xxx/archive](http://localhost:3000/xxx/archive) it appears a error message. So I must  
change the routes.rb but I don’t know how…  
Now when I use [http://localhost:3000/xxx/archive](http://localhost:3000/xxx/archive) the interpreter means,  
that archive is an id and not a method.

You need to specify that your resource have a new method, i.e :

map.resources user do |users|  
user.resources :tournament, :member=\>{:stats=\>:get }  
end

And now you can request the url  
“/users/:user\_id/tournaments/:tournament\_id/stats” with  
stats\_user\_tournament(@user, @tournament)
