标签在哪里保存在acts_as_taggable_on

好的，我试图保持简单的事情，并在轨道控制台测试..但是，我似乎无法弄清楚如何保存标签并再次读出它们。正如你可以从下面的贴看，我救不了@consumer对象（标签），然后读出标签..标签在哪里保存在acts_as_taggable_on

而且，我找不到标签或标记为我的数据库中的表格。感谢您帮助我理解这一点。

编辑：

我想我看到的问题..在表的Tagging我看到ID，TAG_ID，taggable_id，taggable_type，tagger_id，tagger_type，上下文列..行似乎完成tagger_id除外和tagger_type。你认为这与标签没有关联到消费者ID有什么关系吗？我想问题是，Consumer.id实际上应该在标记表中出现在哪里。目前，Consumer.first.id不在标记中的任何列！该Consumer.first.id == 30

您的标记表对我来说看起来很好。 – 2013-02-15 01:10:21

尝试通过

@consumer.tag_list << "foo" 
@consumber.save

追加到TAGS_LIST的阵列然后保存

而且acts_as_taggable_on并在创建一个名为提交您的标签案件。如果您没有看到它，您可能需要运行迁移。
