我試圖使用快遞發送數據,但由於某種原因它丟失了部分數據。Express res.json()丟失數據
function(err, data) {
if (err) console.log(err);
console.log(data);
res.json(data);
}
可變數據看起來像(簡體):
{field1: 'value1', field2: 'value2', field3: {subfield: 'subvalue'}}
但在瀏覽器中我收到:
{field1: 'value1', field2: 'value2', field3: null }
難道我做錯了什麼或失去了一些東西?
更新:
的完整代碼
UserReadingData.find({
UserId: {
"$exists": true,
"$eq": user._id
},
InFuture: false,
Stopped: false
})
.populate('SeriesId', 'SeriesName')
.exec(function(err, data) {
if (err) console.log(err);
console.log(data);
res.json(data);
});
而且SeriesId在瀏覽器爲null。
更新2:執行console.log(數據)的
結果:
{ Issues:
[ 575efe1c3d6d04662a2cd1c4
575efe1c3d6d04662a2cd1d3 ],
Stopped: false,
InFuture: false,
__v: 0,
SeriesId:
{ SeriesName: 'Test name',
_id: 575efe1b3d6d04662a2cd188 },
UserId: 561c080aa849427a8699cafd,
_id: 575f0981ddac1c802d9d1536 }
更新3:
我的模式
var seriesSchema = mongoose.Schema({
Meta: metaInformationSchema,
SeriesName: String,
Description: String,
Creators: [creatorsSchema],
Featured: [featuredSchema],
PublisherName: String,
IsStoryArc: Boolean,
Issues: [{
type: mongoose.Schema.Types.ObjectId,
ref: 'Issue'
}]}, {
collection: 'library'});
var userReadingDataSchema = mongoose.Schema({
UserId: {
type: mongoose.Schema.Types.ObjectId,
ref: 'User'
},
SeriesId: {
type: mongoose.Schema.Types.ObjectId,
ref: 'Series'
},
Issues: [{
type: mongoose.Schema.Types.ObjectId,
ref: 'Issue'
}],
InFuture: Boolean,
Stopped: Boolean}, {collection: 'readingdata'});
我從SQL來了,這是第一當我用mongo的時候。
數據究竟是什麼?它來自哪裏? – robertklep
我使用完整代碼更新了一個問題 – emwsc
user.id'確實存在於數據庫中嗎? – peteb
