ruby-on-rails-3 - 找不到生成器 acts_as_taggable_migration

Question

在我的 rails3 应用程序中，我通过命令“rails plugin install acts_taggable_on_steroids”安装了 acts_as_taggable_on_steroids 并且它已安装，但现在迁移给我带来了问题。

我运行“rails generate acts_as_taggable_migration”，但出现错误“找不到生成器acts_as_taggable_migration”，请帮忙

Answer 1

设法通过 3 个步骤找出解决方法:

1) <b>$ rails generate migration acts_as_taggable</b><br/>



<pre><code> invoke active_record
create db/migrate/20110710214842_acts_as_taggable.rb
</code></pre>



2) 用迁移信息覆盖
$ cat lib/ruby/gems/1.8/gems/acts_as_taggable_on_steroids-1.2/generators/acts_as_taggable_migration/templates/migration.rb > 20110710223844_acts_as_taggable_migration.rb

3) 迁移

<b>$ rake db:migrate</b>
(in c:/Sites/bon)
==  ActsAsTaggable: migrating =================================================
==  ActsAsTaggable: migrated (0.0000s) ========================================

==  ActsAsTaggableMigration: migrating ========================================
-- create_table(:tags)
   -> 0.0020s
-- create_table(:taggings)
   -> 0.0010s
-- add_index(:taggings, :tag_id)
   -> 0.0010s
-- add_index(:taggings, [:taggable_id, :taggable_type])
   -> 0.0010s
==  ActsAsTaggableMigration: migrated (0.0140s) ===============================

用 <b>$ rake db:migration:status</b> 验证
