以上是帖子contorller（post_tags是帖子和标签之间的中间表），视图是这样的。
@post.post_tags.build
当我编辑帖子时，与帖子相关的标签会正确显示，但新的选择框会带有＆＃34;选择名称＆＃34;也创造了。我不想要新的选择框，我也不知道为什么选择框被创建。
我该如何解决？
谢谢， 肯

使用间接关系时，请不要关注连接模型。 ActiveRecord将为您创建它们。
让我们说：
class Post < ApplicationRecord
has_many :tags, through: :taggings
end
class Tag < ApplicationRecord
has_many :posts, through: :taggings
end
class Tagging < ApplicationRecord
belongs_to :tag
belongs_to :post
end
这将让我们通过以下方式标记帖子：
@post.tags < @tag
或者通过以下方式创建标签：
@post.tags.create(name: '#yolo')
如果您想创建一个用户可以选择标签的选择标签或复选框，请使用collection helpers：
<%= form_for(:post) do |f| %>
<%= f.collection_check_boxes :tag_ids, Tag.all, :id, :name %>
<% end %>
特殊的relation_name_ids setter可以从一组id中动态创建/销毁关联。最好的事情是，当你使用HABTM或has_many through:时，Rails会处理你的加入。
