運行時用於關聯的rails服務器的棄用警告

Question

我在Rails 4應用程序中使用了letsrate gem。我已經添加了寶石到我的lib文件，並改變了它有點爲使其使用Rails 4.現在的工作，我得到一個過時的警告這樣的：

DEPRECATION WARNING: The following options in your Performer.has_many :rates_without_dimension declaration are deprecated: :conditions. Please use a scope block instead. For example, the following: 

    has_many :spam_comments, conditions: { spam: true }, class_name: 'Comment' 

should be rewritten as the following: 

    has_many :spam_comments, -> { where spam: true }, class_name: 'Comment' . (called from letsrate_rateable at /home/aravind/Documents/dev/gw-c4u/lib/letsrate/lib/letsrate/model.rb:76) DEPRECATION WARNING: The following options in your Performer.has_one :rate_average_without_dimension declaration are deprecated: :conditions. Please use a scope block instead. For example, the following: 

    has_many :spam_comments, conditions: { spam: true }, class_name: 'Comment' 

should be rewritten as the following: 

    has_many :spam_comments, -> { where spam: true }, class_name: 'Comment' . (called from letsrate_rateable at /home/aravind/Documents/dev/gw-c4u/lib/letsrate/lib/letsrate/model.rb:79) DEPRECATION WARNING: The following options in your Performer.has_many :performance_rates declaration are deprecated: :conditions. Please use a scope block instead. For example, the following: 

    has_many :spam_comments, conditions: { spam: true }, class_name: 'Comment' 

should be rewritten as the following: 

    has_many :spam_comments, -> { where spam: true }, class_name: 'Comment' . (called from block in letsrate_rateable at /home/aravind/Documents/dev/gw-c4u/lib/letsrate/lib/letsrate/model.rb:84) DEPRECATION WARNING: The following options in your Performer.has_one :performance_average declaration are deprecated: :conditions. Please use a scope block instead. For example, the following: 

    has_many :spam_comments, conditions: { spam: true }, class_name: 'Comment' 

should be rewritten as the following: 

    has_many :spam_comments, -> { where spam: true }, class_name: 'Comment' . (called from block in letsrate_rateable at /home/aravind/Documents/dev/gw-c4u/lib/letsrate/lib/letsrate/model.rb:91) 

產生這樣的錯誤文件的一部分是這樣的：

module ClassMethods 

def letsrate_rater 
    has_many :ratings_given, :class_name => "Rate", :foreign_key => :rater_id  
end  

def letsrate_rateable(*dimensions) 
    has_many :rates_without_dimension, :as => :rateable, :class_name => "Rate", :dependent => :destroy, :conditions => {:dimension => nil} 
    has_many :raters_without_dimension, :through => :rates_without_dimension, :source => :rater 

    has_one :rate_average_without_dimension, :as => :cacheable, :class_name => "RatingCache", 
      :dependent => :destroy, :conditions => {:dimension => nil} 


    dimensions.each do |dimension|   
    has_many :"#{dimension}_rates", :dependent => :destroy, 
            :conditions => {:dimension => dimension.to_s}, 
            :class_name => "Rate", 
            :as => :rateable 

    has_many :"#{dimension}_raters", :through => "#{dimension}_rates", :source => :rater   

    has_one :"#{dimension}_average", :as => :cacheable, :class_name => "RatingCache", 
            :dependent => :destroy, :conditions => {:dimension => dimension.to_s} 
    end              
end 

我試圖使：依賴=>：破壞的線的最後部分和不斷變化的條件=> {：尺寸=> dimension.to_s}至 - > {：尺寸=> dimension.to_s}。它只會拋出錯誤。我究竟做錯了什麼？

Answer 1

範圍（或lambda）必須在第二個參數之後的選項

has_one :rate_average_without_dimension, -> { where dimension: nil }, { :as => :cacheable, :class_name => "RatingCache", :dependent => :destroy } 

has_one at APIDock

Answer 2

嘗試：

-> { where(:dimension => dimension.to_s)}
