我需要查找/查询名称为==“DFM”的商城并将数据推送到show_times数组，任何人都可以帮忙！哪种方法可以解决这个问题。我已经使用_id查询了它并且有了这个文档。现在我怎么能推送show_times？我正在使用mongoose v5.5.1

Answer 1

试试这个，它基本上插入showtime，它在商场数组中找到名称字段等于DFM，$运算符用于此

model.update(
       { _id: "givenObjectId",
         "malls.name" : "DFM"
       },
       {
          $push : {"malls.$.show_times" : data }
       }
    )

More details on the $ operator

在MongoDB中搜索并推送数组到嵌套对象数组
