[英]Mongoose. Update by document id throws [TypeError: Cannot read property '_id' of undefined]
There is my code: 有我的代码:
var fileModel = context.models.File,
query = {
_id: context.models.ObjectId("532083358ab1654c0c8b4ced") // TODO: for debug, change after update fix
},
update = {
description: context.data.description,
userId: context.data.userId ?
context.models.ObjectId(context.data.userId) : undefined,
isAdded: true
};
fileModel.update(query, update, { multi: true }, function (err) {
if (err) {
console.log('update');
console.log(err);
context.sendJson({ success: false, err: err });
}
else {
context.sendJson({ success: true });
}
});
There is my Schema: 有我的架构:
var fileSchema = new schema({
path: { type: String, required: true, validate: [validateName, 'a path is required'] },
isApproved: { type: Boolean, default: false },
isAdded: { type: Boolean, default: false },
name: { type: String, required: true, validate: [validateName, 'a name is required'] },
description: { type: String },
userId: { type: schema.Types.ObjectId },
updated: { type: Date, default: Date.now },
size: { type: Number }
}, { autoIndex: false });
When I try to update document by id I see this messages in console: 当我尝试通过ID更新文档时,我在控制台中看到以下消息:
update
[TypeError: Cannot read property '_id' of undefined]
I think problem in 我认为有问题
userId: context.data.userId ?
context.models.ObjectId(context.data.userId) : undefined,
But I don't understand how fix it. 但我不知道如何解决。
I solve this by separate part of my code. 我通过代码的单独部分解决了这个问题。 But I can't understand what's wrong in my first solution.
但是我不明白我的第一个解决方案出了什么问题。 That's working code:
那是工作代码:
var fileModel = context.models.File,
query = {
_id: {
$in: context.data.files.map(function (el) {
return context.models.ObjectId(el);
})
}
},
update = {
description: context.data.description,
isAdded: true
};
if (context.data.userId){
update.userId = context.models.ObjectId(context.data.userId);
}
fileModel.update(query, update, { multi: true }, function (err) {
if (err) {
console.log('update');
console.log(err);
context.sendJson({ success: false, err: err });
}
else {
context.sendJson({ success: true });
}
});
