Ruby on rails 我可以在一个型号上有两个计数器缓存吗？

我有一个用户模型和一个Imagevote模型

class Imagevote < ActiveRecord::Base
    belongs_to :voter, class_name: "User"
    belongs_to :voted, class_name: "User"

class User < ActiveRecord::Base
  has_many :imagevotes, foreign_key: "voted_id", dependent: :destroy
  has_many :reverse_imagevotes, foreign_key: "voter_id", dependent: :destroy

class-Imagevote

我可以在用户模型中为“投票计数”和“投票计数”属性设置计数器缓存吗

如果是，我应该这样做：

class Imagevote < ActiveRecord::Base
        belongs_to :voter, class_name: "User", :counter_cache => true
        belongs_to :voted, class_name: "User", :counter_cache => true

class-Imagevotetrue
属于：投票，类名称：“用户”，计数器缓存=>true

我是否需要笨拙地将新属性命名为“voteds_count”和“Votters_count”，或者上述功能是否有效？

是的，您可以按以下方式执行：

    belongs_to :voter, class_name: "User", :counter_cache => true
    belongs_to :voted, class_name: "User", :counter_cache => true

    belongs_to :voter, class_name: "User", :counter_cache => "voter_count"
    belongs_to :voted, class_name: "User", :counter_cache => "voted_count"

如果要指定自定义列名，请按如下操作：

    belongs_to :voter, class_name: "User", :counter_cache => true
    belongs_to :voted, class_name: "User", :counter_cache => true

    belongs_to :voter, class_name: "User", :counter_cache => "voter_count"
    belongs_to :voted, class_name: "User", :counter_cache => "voted_count"

阅读Rails指南中的选项。

。我不知道您可以指定自定义列名。对我来说更优雅。再次非常感谢你，科蒂。
