我试图使用猫鼬来编辑和更新表单。该代码对我来说似乎很好,但是它不起作用。我已经尝试了很多方法,但是更新的版本仍然相同,我使用放置路由发送表单,当我将req.body.studentInfo输出到控制台时,它是正确的,但是更新保持不变。请帮助
这是我的模式
var mongoose = require("mongoose");
var uniqueValidator = require('mongoose-unique-validator');
var passportLocalMongoose = require("passport-local-mongoose");
var mongoose = require("mongoose");
var UserSchema = new mongoose.Schema({
studentInfo: {
first_name: String,
middle_name: String,
last_name: String,
street: String,
town: String,
city: String,
region: String,
country: String,
studentId: String,
day: Number,
month: String,
year: Number,
},
username: {type: String, required:true, unique:true},
passport: String
});
UserSchema.plugin(uniqueValidator);
UserSchema.plugin(passportLocalMongoose);
module.exports = mongoose.model("StudentInfo", UserSchema);
这是我的App.js
app.put('/:id', function(req,res){
StudentInfo.findByIdAndUpdate(req.params.id, {$set: req.body.studentInfo}, function(err, updated){
console.log(req.params.id);
console.log(req.body.studentInfo);
if(err) {
console.log(err);
}
else {
res.redirect('/' + req.params.id);
}
});
});
The studentInfo is an object that contains the names of each variables in my form which I name was studentInfo[name of variable]. Please help

应该指定mongoose
返回更新的文档-默认情况下,它返回原始文档(这也是mongodb的行为)。我认为,如果代码更改为此:
StudentInfo.findByIdAndUpdate(req.params.id, {$set: req.body.studentInfo}, { new: true }, function(err, updated){
...
});
您将在回调中收到更新的文档。

正如@Denny在回答中所提到的,猫鼬在通过{new : true }
选项之前不会在回调中返回更新的文档。
有关详细信息和可用选项,请检查findByIdAndUpdate Docs
