I get the below error on my rails application when I try to login or register (I'm using the Devise GEM for logins).
Routing Error
No route matches {:controller=>"devise/products"}
All the source code for the application can be found here: https://github.com/rossmc/topsnowboards
I've tried changing the link_to in application.html.erb & product/index.html.erb from:
<%= link_to 'sign in', new_user_session_path %>
to:
<%= link_to 'sign in', :controller => "/products", new_user_session_path %>.
But this just throw up more errors.
Interestingly the login features & routes were working fine before I added a partial for the shopping cart, which I placed in the application.html.erb on my last commit. When I remove this partial the routing error disappears but I loose my partial views/cart/_cart.html.erb.
Below is the console dump from when I try to login & run the rake routes command. Thanks in advance for taking the time to look at this.

Found it? The log shows it has rendered a bunch of partials, down to cart/_cart.html.erb. It even tells you the error happens on line 49. Now what's on line 49? This:
<%= link_to 'Keep Shopping', :controller => :products %>
<%= link_to 'Empty Cart', :controller => "cart", :action => "clearCart" %>
<%= link_to 'Proceed to Check Out', :controller => "cart", :action => "createOrder" %>
As Ryan rightly points out in the following comment, Rails is looking for a partial scoped under Devise since this is the one under which you're rendering.
More simply, you can just feed it the route name (the one you'll find in rake routes) to which you add _path for a helper to form a URL. products_path ends up being the URL string for products#index.
Which gives in your case
<%= link_to 'Keep Shopping', products_path %>
<%= link_to 'Empty Cart', clearCart_path %>
<%= link_to 'Proceed to Check Out', checkout_path %>
Listen to your stack traces, they're talking to you!
Way late to the party, but this was my solution. Simply prefix the controller as absolute with "/". A little long and ugly, but returns link for a controller/action or a route passed. I use it to build menus driven from sql table.
# dynamic link_to
def menu_link(params, html_options=nil)
if params[:controller].present?
link_to params[:display], {controller: "/#{params[:controller]}", action: params[:resource]}, default_navigation_options(html_options)
elsif params[:route].present?
link_to params[:display], params[:route], default_navigation_options(html_options)
end
end
