删除查看文件的链接

发布模型
has_many :comments, dependent: :destroy
accepts_nested_attributes_for :comments
注释模型
belongs_to :post
删除 html 动词也在帖子控制器上传播有什么原因吗?而不仅仅是呼吁show
行动?
问题是由查看文件上的删除链接引起的
= link_to "delete", [@post, comment], method: :DELETE, remote: true
出于某种原因,带有方法 DELETE 的 ajax 请求似乎传播到第一个 DELETE 请求之外。
我删除了remote: true
,它现在向帖子发出 GET 请求而不是 DELETE 请求。
= link_to "delete", [@post, comment], method: :DELETE
我仍然不明白为什么会发生这种情况。
