Question

我已将我的应用程序的rails版本升级到4.1.0。在升级时，我已经从Gemfile升级了所有宝石，Gemfile也将act-as-taggable-on升级到3.1.1。

但升级后，当我尝试在相应对象上添加标记时，它会失败，并显示以下错误。

  post = Post.last
  post.tag_list = "development"
  post.save

错误：列＆＃34; taggings_count＆＃34;不存在

详细信息错误在这里：

SQL (0.9ms)  UPDATE "tags" SET "taggings_count" = COALESCE("taggings_count", 0) - 1 WHERE "tags"."id" = 3146

Answer 1

我们必须这样做，

rake acts_as_taggable_on_engine：install：migrations

由于act-as-taggable-on已添加了新的迁移。

升级到rails 4.1后，act-as-taggable-on无效
