Nesting under the Devise in Rails4

I have a problem with Controller Show Product. Can anyone help me out?

No route matches {:action=>"show", :controller=>"products", :id=>nil, :vendor_id=>"3"} missing required keys: [:id]

   <td>
     <%= link_to 'Show', vendor_product_path(current_vendor, @product) %><br>
     <%= link_to 'Edit', edit_product_path(product) %><br>
     <%= link_to 'Destroy', product, method: :delete, data: { confirm: 'Are you sure?' } %>
   </td>

my controller in product

  def show
    @product = Product.find(params[:vendor_id])
  end

If you're trying to find all the products for a specific vendor, it would be something like:

def show
  @vendor_products = Vendor.find(params[:vendor_id]).products
end

If you are just trying to find a single product by id:

def show
  # Since :id is currently nil in params, this will not work
  @product = Product.find(params[:id])
end

In the view, where are you getting @product from? Seems like @product is not yet saved to the database, and so it is nil in the view (in the line <%= link_to 'Show', vendor_product_path(current_vendor, @product) %>. Which view file have you shown, and what is the corresponding controller action?

In that controller action, make sure you add a line to save the product @product.save

In case the @product is valid, then try passing in the fields explicitly:

<%= link_to 'Show', vendor_product_path(:vendor_id => current_vendor.id, :id => @product) %>
