Notifications Rails 5.2无法使用kaminari和通知进行分页

我的一些文件：

gem 'rails', '~> 5.2'
gem 'notifications', '~> 0.6.0'
gem 'kaminari'

# notifications_controller.rb

module Notifications
  class NotificationsController < Notifications::ApplicationController
    def index
      @notifications = notifications.includes(:actor).order("id desc").page(params[:page])
      unread_ids = @notifications.reject(&:read?).select(&:id)
      Notification.read!(unread_ids)
      @notification_groups = @notifications.group_by { |note| note.created_at.to_date }
    end

    def clean
      notifications.delete_all
      redirect_to notifications_path
    end

    private

    def notifications
      raise "You need reqiure user login for /notifications page." unless current_user
      Notification.where(user_id: current_user.id)
    end
  end
end

mount Notifications::Engine, at: "notifications"

# notifications/notifications/index.html.erb

<div class="paginationBox">
   <%= paginate @notifications,left:2,right:1,window: 1 %>
</div>

NoMethodError - undefined method `total_pages' for #<Notification::ActiveRecord_Relation:0x00007fcfacae6dd8>:
  app/views/notifications/notifications/index.html.erb:33:in `_app_views_notifications_notifications_index_html_erb__2430601159943313679_70264929101860'

我的

通知\u controller.rb

如下：

gem 'rails', '~> 5.2'
gem 'notifications', '~> 0.6.0'
gem 'kaminari'

# notifications_controller.rb

module Notifications
  class NotificationsController < Notifications::ApplicationController
    def index
      @notifications = notifications.includes(:actor).order("id desc").page(params[:page])
      unread_ids = @notifications.reject(&:read?).select(&:id)
      Notification.read!(unread_ids)
      @notification_groups = @notifications.group_by { |note| note.created_at.to_date }
    end

    def clean
      notifications.delete_all
      redirect_to notifications_path
    end

    private

    def notifications
      raise "You need reqiure user login for /notifications page." unless current_user
      Notification.where(user_id: current_user.id)
    end
  end
end

mount Notifications::Engine, at: "notifications"

# notifications/notifications/index.html.erb

<div class="paginationBox">
   <%= paginate @notifications,left:2,right:1,window: 1 %>
</div>

NoMethodError - undefined method `total_pages' for #<Notification::ActiveRecord_Relation:0x00007fcfacae6dd8>:
  app/views/notifications/notifications/index.html.erb:33:in `_app_views_notifications_notifications_index_html_erb__2430601159943313679_70264929101860'

My

index.html

关于这样的通知：

gem 'rails', '~> 5.2'
gem 'notifications', '~> 0.6.0'
gem 'kaminari'

# notifications_controller.rb

module Notifications
  class NotificationsController < Notifications::ApplicationController
    def index
      @notifications = notifications.includes(:actor).order("id desc").page(params[:page])
      unread_ids = @notifications.reject(&:read?).select(&:id)
      Notification.read!(unread_ids)
      @notification_groups = @notifications.group_by { |note| note.created_at.to_date }
    end

    def clean
      notifications.delete_all
      redirect_to notifications_path
    end

    private

    def notifications
      raise "You need reqiure user login for /notifications page." unless current_user
      Notification.where(user_id: current_user.id)
    end
  end
end

mount Notifications::Engine, at: "notifications"

# notifications/notifications/index.html.erb

<div class="paginationBox">
   <%= paginate @notifications,left:2,right:1,window: 1 %>
</div>

NoMethodError - undefined method `total_pages' for #<Notification::ActiveRecord_Relation:0x00007fcfacae6dd8>:
  app/views/notifications/notifications/index.html.erb:33:in `_app_views_notifications_notifications_index_html_erb__2430601159943313679_70264929101860'

它不显示任何错误，但

kaminari

无法分页所有通知

那么，我哪里有错误呢？你能帮帮我吗？非常感谢

你在后端使用哪个数据库？你的数据库中是否有通知记录？我使用了

Mysql

，我可以在我的数据库中获得

notifications

记录。但是现在我无法在notifications

index.html.erb

中分页

total_pages

。谢谢@Abid lqbal…是因为数据库中没有通知记录吗？
