no route match rails 5

am trying to add routes to my rails app but everytime i try to load the index page it returns no route match. my

product.rb

belongs_to :category
extend FriendlyId
friendly_id :name, use: [:slugged, :finders]
 default_scope { where(active: true) }
end

and here is my category.rb 

has_many :products
  extend FriendlyId
 friendly_id :name, use: [:slugged, :finders]

and my routes are setup like this 

    resources :categories
    get '/products/:category_id/:id/', to: 'products#show', as: 'product'
    resources :products

in my index page i have it like this

<%= link_to product, class: "card" do %>
<div class="product-image">
<%= image_tag product.productpic.url if product.productpic? %>
    </div>

      <div class="product-text">
        <h2 class="product-title"> <%= product.name %></h2>
          <h3 class="product-price">£<%= product.price %></h3>
      </div>

        <% end %>
    <% end %>

but when ever i load the page in my broser i get 

No route matches {:action=>"show", :category_id=>#<Product id: 4, name: "virgin hair", price: #<BigDecimal:7fd0af3ffb10,'0.3E3',9(18)>, created_at: "2016-07-19 12:34:34", updated_at: "2016-07-19 12:41:36", slug: "virgin-hair", productpic: "longhair.jpg", pdescription: "this a brazilian virgin hair", active: true, category_id: 2>, :controller=>"products"} missing required keys: [:id]

What you're trying to do is called nested routing.

And this is how you make it right:

# config/routes.rb
resources :categories do
  resources :products
end

in your controller:

# app/controllers/products_controller.rb
...
  def show
    @category = Category.find(params[:category_id])
    @product = @category.products.find(params[:id])
  end
...

and in your view (to link the above controller action):

<%= link_to 'Awesome Product!', category_product_path(@category, @product) %>

Defining routes like above will let you make paths like this:

/categories/123/products/1

EDIT

To find a record using the name you could do something like this in your controller:

# app/controllers/products_controller.rb
...
  def show
    @category = Category.find_by!(name: params[:category_id])
    @product = @category.products.find_by!(name: params[:id])
  end
...

You are passing product object in place of category_id. Try this,

 :category_id => product.category_id
