Mongoose - findByIdAndUpdate - doesn't work with req.body
提问by Robert
I have a problem with update documents in mongodb over mongoose.
我在通过 mongoose 更新 mongodb 中的文档时遇到问题。
My model bellow:
我的模型如下：
var mongoose = require('mongoose');
var bcrypt = require('bcrypt-nodejs');
var UserSchema = new mongoose.Schema({
first_name:{
type: String
},
last_name:{
type: String
},
email:{
type: String,
unique: true,
required: true
},
password:{
type: String,
required: true
},
is_active:{
type: Boolean,
default: true
},
last_login:{
type: Date
}
});
module.exports = mongoose.model('User', UserSchema);
Controller put function bellow:
控制器放置功能如下：
exports.updateUser = function (req, res) {
console.log(req.body);
User.findByIdAndUpdate(req.body.user_id, {$set:req.body}, function(err, result){
if(err){
console.log(err);
}
console.log("RESULT: " + result);
});
res.send('Done')
}
Output on console:
控制台输出：
Listening on port 3000... { first_name: 'Michal', last_name: 'Test' }
PUT /api/users/54724d0fccf520000073b9e3 200 58.280 ms - 4
The printed params are provided as form-data (key-value). Looks that is not working at least for me any idea what is wrong here?
打印的参数作为表单数据（键值）提供。看起来至少对我不起作用，知道这里有什么问题吗？

You have to use req.params.user_idinstead req.body.user_id
你必须req.params.user_id改用req.body.user_id
exports.updateUser = function (req, res) {
console.log(req.body);
User.findByIdAndUpdate(req.params.user_id,{$set:req.body}, function(err, result){
if(err){
console.log(err);
}
console.log("RESULT: " + result);
res.send('Done')
});
};

I found the mistake. Note that I'm calling
我发现了错误。请注意，我正在打电话
req.body.user_id
req.body.user_id
where should be
应该在哪里
req.params.user_id
req.params.user_id
- url is

Further, the req.bodywould have key value as Text and realized as Stringobject, inside the code. Thus, it is useful to parse the string into JSON using JSON.parse(req.body.user)- while the useris the key and { first_name: 'Michal', last_name: 'Test' }is the value.
此外，req.body将键值作为文本并String在代码内部实现为对象。因此，使用JSON.parse(req.body.user)-将字符串解析为 JSON 很有用，而user是键和{ first_name: 'Michal', last_name: 'Test' }值。
console.log(req.body);
var update = JSON.parse(req.body.user);
var id = req.params.user_id;
User.findByIdAndUpdate(id, update, function(err, result){
if(err){
console.log(err);
}
console.log("RESULT: " + result);
res.send('Done')
});
Note: the updatevalue is sent to Mongo DB as
注意：更新值发送到 Mongo DB 作为
{$set: { first_name : 'Michal`, last_name: 'Test' }
