如何糾正HABTM關係中的'SystemStackError（堆棧級別太深）'？

Question

我試圖調試/解決我試圖添加到我的報告模型關聯時收到的錯誤。我不斷收到我讀過的SystemStackError (stack level too deep)錯誤，可能是由於無限循環調用 - 但我似乎無法找到它。這是我的模型和控制器。當我嘗試將「警報」添加到「報告」時，我已縮小範圍。如果我需要包含更多，請讓我知道。謝謝！

報告

class Report < ActiveRecord::Base 
    self.inheritance_column = :disabled 

    # Associations 

    has_and_belongs_to_many :alerts 
    accepts_nested_attributes_for :alerts, allow_destroy: true, reject_if: :all_blank 

    validates_uniqueness_of :author_id, scope: :player_id 

    public 

    def all_alerts 
     alerts_string = "" 
     alerts.order(letter: :asc).each do |a| 
     alerts_string += a.letter.upcase 
     end 
     alerts_string 
    end 

end 

警報

Answer 1

這似乎是一個可能的子彈問題給我，也許你應該把它作爲一個問題發佈在他們的Github？子彈有一段代碼在它的lib/acive_record42.rb文件：

alias_method :origin_has_cached_counter?, :has_cached_counter? 
def has_cached_counter?(reflection = reflection()) 
    result = origin_has_cached_counter?(reflection) 
    ... 
end 

看起來可能被生成SLTD的地方，但我錯了巨大的可能性。
