Hi,
im a rails newbie, so please be gentle:

let's say category habtm products and i've got a product with the id
7.

when i use the url

/categories/7/products

should the server show me only the categories of product 7?

On my Server it always shows all categories i have.

 How do i solve this the right way?

I edited the routes.rb so, that

  map.resources :categories, :has_many => [:products]

But this does not change anythings, using
/categories/7/products always leads to the index action of the
products controller.

Is the right way to test in the index action of the products
controller whether category_id is set in params and use this
information to only show products of this category? Or is there a
better way?

Thanks,

HansFH
