指定依赖的gem(environment.rb)：
# Require the latest version of haml
config.gem "haml"
# Require a specific version of chronic
config.gem "chronic", :version => '0.2.3'
# Require a gem from a non-standard repo
config.gem "hpricot", :source => "http://code.whytheluckystiff.net"
# Require a gem that needs to require a file different than the gem's name
# I.e. if you normally load the gem with require 'aws/s3' instead of
# require 'aws-s3' then you would need to specify the :lib option
config.gem "aws-s3", :lib => "aws/s3"
end
然后解压到vender：
rake gems:unpack

how to get your grub back when you reinstalled your windoz?
Here are the quickfire steps to use the acts_as_taggable gem...
1. In your project database, add two tables, tags and tags_[model you're linking to], here's an example sql script:
`id` int(6) UNSIGNED NOT NULL AUTO_INCREMENT,
`title` varchar(50) NOT NULL DEFAULT '',
`author` varchar(50) NOT NULL DEFAULT '',
`description` text NOT NULL,
`created_on` datetime NOT NULL DEFAULT '0000-00-00 00:00:00',
`updated_on` datetime NOT NULL DEFAULT '0000-00-00 00:00:00',
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
CREATE TABLE `tags` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`name` varchar(30) NOT NULL DEFAULT '',
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
CREATE TABLE `tags_books` (
`tag_id` int(11) NOT NULL DEFAULT '0',
`book_id` int(11) NOT NULL DEFAULT '0'
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
2. at a command prompt, from in your project directory, run
gem install acts_as_taggable
3. Add this line right above the end in your environment.rb
require_gem 'acts_as_taggable'
4. Create a tag model. You can do this manually or with the generator like so:
ruby script\generate model Tag
5. In your target object's model.rb file (books.rb in this case) add
acts_as_taggable
6. In your target object's controller (books_controller.rb for us) add this line under your
if @books.save line..
@book.tag(params[:tags])
7. Add this to your _forms partial
tags for this book: <%= text_field_tag('tags', '') %>
8. To get the items to show in yor list.rhtml view, you can call them with this
<%= book.tag_names.join(" ") %>
That's the quick way to get acts_as_taggable working. For more functionality, check this out.
