def exact_column(*names)

  exact_column_names = exact_column_names||[]
  exact_column_names += names

  names.each do |name|
    name = name.to_s
    instance_eval do
      scope :"#{name}_is", ->(value) { where "#{name}_exact_signature" => exact_signature(self, name, value) }
      before_save do send "#{name}_exact_signature=", self.class.exact_signature(self.class, name, send(name)) end
    end
  end

end

#exact_signature(klass, name, value, secret_key_base: ) ⇒ Object

计算精确索引列的值。此方法被 exact_column 方法调用。
