Ruby on rails 3 客户端验证自定义方法未定义

使用自定义验证器加载表单会生成NoMethodError

undefined method `validates_soggetti'

设置

gem 'rails', '3.2.13'
gem 'client_side_validations', :github => 'bcardarella/client_side_validations', :branch => '3-2-stable'

初始值设定项已阻止未注释的附加邮件。
app/validators/soggetti_validator.rb包含

class SoggettiValidator < ActiveModel::EachValidator

  def validate(record)
    unless :quantita >= :soggetti
      record.errors.add(:soggetti, :too_big) 
    end
  end

  module ActiveModel::Validations::HelperMethods
    def validates_soggetti(*attr_names)
      validates_with SoggettiValidator, _merge_attributes(attr_names)
    end
  end

 end

---

只有自定义验证不会生效。我假设问题在于模块定义。

通过在/liba validations\u helpers.rb下创建包含模块语句的文件来解决

  module ActiveModel::Validations::HelperMethods
    def validates_soggetti(*attr_names)
      validates_with SoggettiValidator, _merge_attributes(attr_names)
    end
  end

并调用相关控制器中的模块

此外，模型还需要指定轨道3：

  validates :height, :presence => true, :numericality => true
  validates :width, :presence => true, :numericality => true
  validates :quantita, :presence => true, :numericality => {:only_integer => true}
  validates :soggetti, :soggetti => true, :numericality => {:only_integer => true}

这与上的说明略有不同 这表明验证了\u myCustomValidation

  module ActiveModel::Validations::HelperMethods
    def validates_soggetti(*attr_names)
      validates_with SoggettiValidator, _merge_attributes(attr_names)
    end
  end

  validates :height, :presence => true, :numericality => true
  validates :width, :presence => true, :numericality => true
  validates :quantita, :presence => true, :numericality => {:only_integer => true}
  validates :soggetti, :soggetti => true, :numericality => {:only_integer => true}
