将对象数组从 React 推送到 mongodb+express 服务器问题

Question

我正在存储对象数组，但它给了我以下错误。

(node:87929) UnhandledPromiseRejectionWarning: ValidationError: Place validation failed: placesToVisit: Cast to embedded failed for value "[{"name":"xczc","location":"zczxc","description":"由于“ObjectParameterError”

，路径“placesToVisit”处的 czxczx“}]”（类型字符串）

这是我的架构：

placesToVisit: [
    {
      name: {
        type: String,
        required: [true, "Please enter the place's name"],
      },
      description:{
        type: String,
        required: [true, "Please enter the place's description"],
      },
      location:{
        type: String,
        required: [true, "Please enter the place's location"],
      }
    },
  ],

这是我的控制器：

exports.createPlace = async (req, res) => {
  
  try {
    const newPlace = await new Place({
    
     placesToVisit:req.body.placesToVisit,
    
    });
    newPlace.save()
    debugger
    res.status(201).json({
        success:true,
        message:"Place Created Successfully",
        newPlace
    })
  } catch (error) {
     return res.status(500).json({
          success:false,
          error:error.message
      })
  }
};

这是我的表单数据结构：

data.append("placesToVisit",JSON.stringify(values.placesToVisit))

您必须将字符串转换为数组：

placesToVisit: JSON.parse(req.body.placesToVisit),
