rails link_to generates unwanted id

Question

I have an index for a model "arbete" and if an :id is supplied it filters the index and shows only the index for the vehicle with the id.

if I create a link_to in the view that shows the whole index again it still generates the index link and the id again even though I haven´t supplied an action or an id.

link_to("show all", :controller => 'arbete')

generates:

<a href="/arbete/index/22">show all</a>

The only solution I have found is to specify :id => ' ' and then I get the link:<a href="/arbete/index">

why is it behaving like this?

Update

arbete_controller.rb

 def index

     @arbetecl = Arbete.order("id ASC").where(:oppen => false)
     if params[:id].present?
     @vehicle = Vehicle.find(params[:id])
      @arbeteop = @vehicle.arbetes.all
      else
     @arbeteop = Arbete.order("id ASC").where(:oppen => true)
   end

link in view

<li><%= link_to "Testarbete", :controller => 'arbete' %></li>

generates if the id params is sent.

<li><a href="/arbete/index/67">Testarbete</a></li>

routes.rb

 match ':controller(/:action(/:id))', :via => [:get, :post]

Im thinking its a desired behaviour but I cant find why and it only happens on this model and controller but its also the only one that gets params to its index action.

You need to specify both action and controller or write full url helper for which you want to generate link.

link_to("show all", {:controller => 'arbete', :action => 'index'})

or

link_to("show all", arbetes_path)
