Question

My current app is using URLs like:

/philsturgeon
/philsturgeon/trip_slug

I have trips attached to users in my model like so:

class Trip < ActiveRecord::Base
    belongs_to :user

    def to_param
        "#{user.username}-#{slug}"
    end
end

Now I have been told about to_param which seems awesome. It means I can use the normal resource linking:

<h4><%= link_to trip.name, trip %></h4>

instead of manually creating strings like this:

redirect_to('/' + current_user.username + '/' + @trip.slug)

Problem is that gives me a hyphen (or dash) separated URL. As soon as I change the URL to_param to #{user.username}/#{slug} (notice the slash instead of the dash) I get an error:

ActionController::RoutingError in
Home#index

Showing
/Users/phil/Scripts/ruby/travlr/app/views/home/index.html.erb
where line #27 raised:

No route matches {:action=>”destroy”,
:controller=>”trips”, :id=>#}

Extracted source (around line #27):

Looks like hard-coding the URI is the only real solution in this situation. Works fine, but not the nicest code.

Thanks to those who answered, but they weren’t quite correct.
