删除 post 方法不适用于已注意到的 gem rails

Question

我有一个带有评论的简单模块查询，我使用通知 gem 向评论添加通知，但是当我删除查询 post 时，它会停止服务器，页面无法正常工作，并删除整个帐户，就像我无法使用该帐户登录一样 again.i 是这个 gem 的新用户。 inquest.rb

class Inquest < ApplicationRecord
acts_as_votable
belongs_to :user,  dependent: :destroy
has_many :comments, -> {order(:created_at => :desc)}, dependent: :destroy
has_many_attached :images 
validates :description, presence: true
has_noticed_notifications model_name: 'Notification'
has_many :notifications, through: :user, dependent: :destroy
validates :title, :presence => true, :length => { 
    :maximum => 250,
    :minimum => 25,
    :tokenizer => lambda { |str| str.scan(/\w+/) },
    :too_long  => "Please limit your summary to %{count} words"
  }

  end

notification.rb

class Notification < ApplicationRecord
 include Noticed::Model
  belongs_to :recipient, polymorphic: true 
 end

comment.rb

class Comment < ApplicationRecord
belongs_to :inquest 
belongs_to :user
validates :content, presence: true

  after_create_commit :notify_recipient
 before_destroy :cleanup_notifications
 has_noticed_notifications model_name: 'Notification' 

 private

 def notify_recipient
Commentnotification.with(comment: self, inquest: inquest).deliver_later(inquest.user)
 end

 def cleanup_notifications
   notifications_as_comment.destroy_all
 end
 end

user.rb

   has_many :notifications, as: :recipient

评论notification.rb

  def message
@inquest = Inquest.find(params[:comment][:inquest_id])
@comment = Comment.find(params[:comment][:id])
@user = User.find(@comment.user_id)
"#{@user.user_name} commented on #{@inquest.title.truncate(10)}"

 end
 def URL
    inquest_path(Inquest.find(params[:comment][:inquest_id]))
 end

Answer 1

问题是您的协会中有 dependent: :destroy：

class Inquest < ApplicationRecord
  belongs_to :user, dependent: :destroy
end

删除了 Inquest 的用户，因此帐户被删除。一个 User 可以有很多 Inquest 并且通常与 User 有很多相关联，所以用其他对象破坏它是一个坏主意。相反，User 模型应该 dependent: :destroy 与一般情况下的关联。
