Vim Videos That Wow! Me

I have been using vim for years, but these two videos change how I use vim tremendously.

Mastering the Vim Languages

Chris Toomey give a talk on vim language. If you wanna learn why vim is so great or use vim more efficiently, you should start with this one. Chris also includes lots of resources in this talk if you want to follow deeply into this topic.

 Let Vim Do The Typing

Presented by George Brocklehurst, talking about vim completing, basically. I found the talk very practically useful and somewhat different form Toomey’s talk.

Rails Namespace, Nested Resource and form_for

Couple days ago, I ran into a problem when I try to use namespace, nested resources and form_for in Rails 3 and ruby 1.9.3. I try to setup some thing similar to this, a namespace :admin, with nested resources :menus, and :menu_items. Here is the routes.rb:

namespace :admin do
  resources :menus do
    resources :menu_items
  end
end

I think it's probably common used case. Unfortunately, I got this error when I try to create a new MenuItem in menu_items/_form.html.erb

undefind method 'admin_menu_items_path' for #<#<Class ...
...
 1: <%= form_for(@admin_menu_item)do |f| %>
      ...
17: end

I realize that the standard scaffolding won't work for me, so I start googling. Right away, I get a lot of hits. It's seem to be a common issue. However, the solutions create quite a confusion for me. I try different solutions, some looking good but don't work! .. Here is what I find working.

 First, in admin/menu_items_controller.rb, method 'new':

def new 
  @menu = Admin::Menu.find(params[:menu_id])
  @menu_item = @menu.menu_items.build
  ...
end

It load up the @menu, and build @menu_item, nothing surprise me. I also get rid of than "admin" prefix. It's simpler that way.
