定义规则并添加它们后，不显示具有Rails 4.2点的优异宝石（无设计）

Question

我已经定义了行动和规则来奖励用户，这要归功于其功绩 。

但是，它不起作用。 在执行奖励动作之后，用户不会获得任何积分。

这是我的代码：

首先，这是我的看法：

<div class="col-md-3 text-center">
<p class="dark-blue"><%= @user.points %></p>
<p class="grey-light">Points</p>
</div>

其次，这是point_rules模型：

#Model/merit/point_rules.rb    
module Merit


    class PointRules include Merit::PointRulesMethods
    def initialize
      score 15, on: 'pages#create', to: [:user]
    end
  end
end

第三，在Controller页面中创建的方法：

    def create
    @comment = Comment.new
    @comment.title = params[:title]
    @comment.content = params[:content]
    @comment.created_at = params[:created_at]
    @comment.score = 0
    @comment.author = User.find(session[:user_id]).user_name
    @comment.user = User.find(session[:user_id])
    @comment.save
    redirect_to "/feed"
    end

最后，merit.rb：

  #config/initializers/merit.rb  
  Merit.setup do |config|
  # Check rules on each request or in background
   config.checks_on_each_request = true

  # Define ORM. Could be :active_record (default) and :mongoid
   config.orm = :active_record

  # Add application observers to get notifications when reputation changes.
  # config.add_observer 'MyObserverClassName'

  # Define :user_model_name. This model will be used to grand badge if no
  # `:to` option is given. Default is 'User'.
   config.user_model_name = 'User'

  # Define :current_user_method. Similar to previous option. It will be used
  # to retrieve :user_model_name object if no `:to` option is given. Default
  # is "current_#{user_model_name.downcase}".
  config.current_user_method = 'current_user'




  # Add application observers to get notifications when reputation changes.
  # config.add_observer 'MyObserverClassName'



end

此外， Forest在CLI中告诉我，模型“ Merit :: ActivityLog”似乎不存在“关联”腰带。

怎么解决呢？

预先谢谢你。

编辑：这是可能的错误[优点]的堆栈跟踪，未找到目标：未初始化的常量页面。

优点不适用于Rails 4.2。

https://github.com/merit-gem/merit/issues/301

你必须用

gem 'merit', '~>2.4'

同样NoMethodError on 'TrueClass#user'的错误NoMethodError on 'TrueClass#user'意味着当期望对象响应#user时，某些东西返回true 。
