我想返回所有聊天对话,其中登录用户(user_id)是参与者。Mongoosejs - 过滤出填充结果
我想填充参与者只返回profile.firstname(可能其他一些版本),然后,我想筛选出参与者,使其不参加阵列中带回是loggedInUser(USER_ID)。
chat.controller.js INDEX
Chat.find({participants: user_id})
.populate('participants', {
select: 'profile.firstname',
where('_id').ne(user_id) // This need to change
})
.exec(function (err, chats) { });
chat.model.js
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
let ChatSchema = new Schema({
participants: [{
type: Schema.Types.ObjectId, ref: 'User'
}],
messages: [{
type: Schema.Types.ObjectId, ref: 'Message'
}],
},
{
timestamps: {createdAt: 'created_at', updatedAt: 'updated_at'}
});
module.exports = mongoose.model('Chat', ChatSchema);
