出于某种原因，当我删除上传的照片时，它所属的相册也会自动删除。

没有任何意义，因为我没有在任何模型上设置“依赖破坏”。

这是终端日志：

相册型号：

class PhotoAlbum < ActiveRecord::Base

    belongs_to :user
    has_many :photos
    belongs_to :photo

    attr_accessible :album_title, :user_id, :photo_id

照片模型：

class Photo < ActiveRecord::Base


    belongs_to :photo_album


    attr_accessible :photo_album_id, :photo_title, :image, :remote_image_url, :banner_axis
    mount_uploader :image, ImageUploader

用户显示视图：

<%= link_to "", @banner, :confirm => 'Are you sure?', :method => :delete, :remote => true %>

用户控制器显示操作：

 def show
   profile_banner_album_id = @user.photo_albums.find_by_album_title("profile banner").id
   @banner = Photo.find_by_photo_album_id(profile_banner_album_id)
 end

我已经离开铁轨一段时间了，所以有点生锈，所以我可能会遗漏一些非常明显的东西。查看日志，我不确定为什么在删除照片后会删除相册。

期待在这里得到一些帮助。亲切的问候

这一行：

[af820895e0bf5c0b031bb5ea297290ee] [127.0.0.1] Completed 302 Found in 46ms (ActiveRecord: 31.9ms)

会建议第一个动作正在完成，同时正在调用第二个动作。photo_gallery#index 中没有什么奇怪的地方吗？还是照片模型上的滤镜？

这意味着销毁操作是通过 JS 在您的相册控制器上调用的。

这不是 Rails 问题，您有另一个 JS 调用在删除照片后破坏了相册。

也许当你点击照片的删除按钮时，相册的删除按钮也会被点击，或者类似的东西......
