[英]How to push returned value into an array mongodb?
我正在為friendRequests獲取正確的數據,該數據正在獲取用戶ID並將其扔到我的貓鼬文件的friendRequest字段中。 當我添加$ push以將數據添加到路由文件中的friendRequest數組中時,它實際上並未插入數據,並向我返回了我創建的err函數。
這是我的路線文件:
exports.addContactPost = function(req, res, err) {
User.findByIdAndUpdate(req.signedCookies.userid, {
$push: {friendRequest: req.body.friendRequest}
}, function(err) {
if(err) {
console.log("post2");
return console.log('error');
}
else {
console.log('postsuccess');
res.json({response: true});
}
});
};
這是貓鼬文件:
var mongoose = require('mongoose'),
Schema = mongoose.Schema,
bcrypt = require('bcrypt-nodejs'),
SALT_WORK_FACTOR = 10;
var UserSchema = new Schema({
email: { type: String, required: true, lowercase:true, index: { unique: true } },
password: { type: String, required: true },
firstName: {type: String, required: true},
lastName: {type: String, required: true},
phone: {type: Number, required: true},
birthday: {type: Date, required: true},
friendRequest: {type: Array},
friend: {type: Array}
});
UserSchema.pre('save', function(next) {
var user = this;
console.log("email exists");
// only hash the password if it has been modified (or is new)
if (!user.isModified('password')) return next();
// generate a salt
bcrypt.genSalt(SALT_WORK_FACTOR, function(err, salt) {
if (err) return next(err);
// hash the password along with our new salt
bcrypt.hash(user.password, salt, null, function(err, hash) {
if (err) return next(err);
// override the cleartext password with the hashed one
user.password = hash;
next();
});
});
});
UserSchema.methods.comparePassword = function(candidatePassword, cb) {
bcrypt.compare(candidatePassword, this.password, function(err, isMatch) {
if (err) return cb(err);
cb(null, isMatch);
});
};
module.exports = mongoose.model('User', UserSchema);
因此,mongo查找與提供的userId匹配的文檔沒有一個數組作為其friendRequest
屬性。 在mongo shell中按ID查看該特定文檔,並對其進行修復,以使friendRequest
是一個數組。
