如何更新子文档？

Question

我想更新子文档 FinanceSchema。这是我的模型

            const FinanceSchema = new mongoose.Schema({
              moneyToBePaid: {
                type: Number,
              },
            
              moneyPaid: {
                type: Number,
              },
            
              moneyToBeReceived: {
                type: Number,
              },
            
              moneyReceived: {
                type: Number,
              },
            });
            
            const UserSchema = new mongoose.Schema({
              financialInformation: [FinanceSchema],
            });
            module.exports=mongoose.model('user',UserSchema)

 

这是路线

我可以发布财务信息

        router.post("/users/:id/profile", async (req, res) => {
          const _id = req.params.id;
          const {
            moneyToBePaid,
            moneyPaid,
            moneyToBeReceived,
            moneyReceived,
          } = req.body;
          const finance = {
            moneyToBePaid,
            moneyPaid,
            moneyToBeReceived,
            moneyReceived,
          };
          try {
            const user = await User.findById(_id);
            user.financialInformation.unshift(finance);
            await user.save();
        }

我无法更新financeInformation(FinanceSchema)。我很困惑如何定义和更新路线。

Answer 1

尝试致电markModified()，因为猫鼬可能不会自动获取更改：

const user = await User.findById(_id);
user.financialInformation.unshift(finance);
user.markModified('financialInformation');
await user.save();

编辑：

如果你想在某个索引处修改financialInformation，你可以简单地执行以下操作：

const user = await User.findById(_id);
user.financialInformation[0].moneyReceived = 1000000;
await user.save();
