我已经安装了 Merit 并设置了一些 points_rules。comment当他们创建一个但没有其他人时，我成功地向我的“用户”添加了积分。

我正在使用设计。

点规则

module Merit
  class PointRules
    include Merit::PointRulesMethods

    def initialize
      score 10, :on => ['user#create', 'user#update'] do |user|
         user.preferred_drink.present?
       end
       score 20, on: 'comments#create', to: :user #is working!
       score 10, on: 'users#update', to: :user
       score 20, on: 'favorite_coffeeshops#create', to: :user  
    end
  end
end

用户.rb

class User < ApplicationRecord
  has_merit
  has_many :favorite_coffeeshops      
  has_many :favorites, through: :favorite_coffeeshops, source: :coffeeshop

  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :validatable, :trackable

favourite_coffeeshop.rb - 加入表。

class FavoriteCoffeeshop < ApplicationRecord
  belongs_to :coffeeshop
  belongs_to :user

用户可以在favorite_coffeeshops表格中添加一个新行，这样就可以正常工作了。

从控制台日志来看，它似乎没有尝试写入绩效模型。

您是否在规则设置后重新启动服务器？可能这是基本原因。我遇到了同样的问题并以这种方式解决。
