Ruby on rails 保存rails中接收的json数据时出现问题

以下是我的json数据：

{
   "authenticity_token"   =>"pdXG/h4Ds0g2ysC564mNSfGe7HfpPWHD+X81u06hJFI=",
   "utf8"   =>"✓",
   "ar_identifier"   =>"14433",
   "bji"   =>   {
      "date"      =>"02-12-2013",
      "ar_bji_o_involveds"      =>      {
         "0"         =>         {
            "name"            =>"h",
            "dob"            =>"",
            "charge"            =>"j"
         },
         "1"         =>         {
            "name"            =>"jkljlkj",
            "dob"            =>"",
            "charge"            =>"jkljklj"
         }
      }
   }
}

我需要循环和保存姓名，出生日期和费用。请不要0，1是不固定的，他们的大小可以达到任何数字

我正在尝试这个：

     counter = 0;
     other = params[:bji][:ar_bji_o_involveds]

     other.each do |other|
       e = MyModel.new(params[:bji][:ar_bji_o_involveds][:counter])
       e.save
       counter+= 1
     end

但保存的数据为空。请帮助我。

您可以尝试以下操作：

 other = params[:bji][:ar_bji_o_involveds]

 other.each do |key, value|
   e = MyModel.new(value)    #Assuming your model has `dob`, `charge` and `name` fields
   e.save!  
 end
