比如我现在有~/app/assets/templates/home.html.slim，然后在某.js.coffee.erb中有写：

window.App.config ['$routeProvider', ($routeProvider) ->
    $routeProvider
        .when '/',
            templateUrl: "<%= asset_path 'home.html' %>"
]

然后很明显 Rails 找不到 home.html…… 有在~/config/initializers/render.rb中写：

Rails.application.assets.register_engine('.slim', Slim::Template)

Rails.application.assets.context_class.class_eval do
  include ActionView::Helpers
  include Rails.application.routes.url_helpers
end

但依然找不到……求大大帮助…………
