For Rails3 applications, you might want to look into making a Railtie for your gem.

對於Rails3應用程序，您可能希望研究為您的gem制作Railtie。

You can do so with:

您可以這樣做：

lib/your_gem/railtie.rb

LIB / your_gem / railtie.rb

require 'your_gem'
require 'rails'
module YourGem
  class Railtie < Rails::Railtie
    rake_tasks do
      require 'path/to/rake.task'
    end
  end
end

lib/your_gem.rb

LIB / your_gem.rb

module YourGem
  require "lib/your_gem/railtie" if defined?(Rails)
end

Though, I had my share of difficulties with requiring the rake.task file in my railtie.rb. I opted to just define my measley one or two tasks within the rake_tasks block.

雖然，我在railtie.rb中要求rake.task文件時遇到了一些困難。我選擇在rake_tasks塊中定義我的一個或兩個任務。

Check out the rdoctask in rake for an example of how to define a task provided by a gem. The task is defined in ruby instead of the rake build language and can be required like so:

查看rake中的rdoctask，了解如何定義gem提供的任務。該任務是用ruby而不是rake構建語言定義的，可以這樣定義：

require 'rake'             # the gem
require 'rake/rdoctask'    # the task

You have to import those tasks in application's Rakefile. This is how it looks in mine (I am using bundler08 to manage my gems):

您必須在應用程序的Rakefile中導入這些任務。這就是我的樣子（我使用bundler08來管理我的寶石）：

%w(gem1 gem2 gem3).each do |g|
  Dir[File.dirname(__FILE__) + "/vendor/bundler_gems/**/#{g}*/tasks/*.rake"].each do |f|
    import f
  end
end

You can write normal rake tasks for a gem and load them like this:

您可以為gem編寫正常的rake任務並加載它們，如下所示：

require 'rake'
load 'path/to/your/tasks.rake'

Also, take a look at thor vs. rake.

另外，看看托爾與耙子。
