Rails 3：在flash消息中显示错误完整消息

Question

这是我的CreditCard模型：

validate :name_is_split_properly
  private
    def name_is_split_properly
      if last_name.blank?
        self.errors[:base] << "Last Name is required"
      end
    end

当用户提交CreditCard时，验证就会发生，这就是我在flash消息中设置错误的方法：

flash[:error] = current_order.errors.full_messages.join('\n')
redirect_to new_order_path(:client_id => params[:client_id])

但出于某种原因，当视图中显示flash[error]时，显示的方式如下：Credit card base Last Name is required ...如何摆脱密钥？

Answer 1

尝试errors.add(:base, "Last Name is required")
