包括模型，除非属性为空 - 节点续集

Question

我正在调用有关用户的信息并希望包含 UserMeetingsReviews，除非属性包含空字符串：complement === ''

如果我使用include: [ where: { complement: '' } ]，它包括所有补码为空字符串的记录，没有问题。要仅获取没有空字符串的记录，我尝试过：

include: [ where: { 'complement': {[Op.ne]: '""'} }, ]

include: [ where: { 'complement != "" '}, ]

include: [ where: [ '`GroupMeetingsReviews`.`complement` != ""' ],]

都抛出一个错误。

这不会引发错误，但会包含空字符串的记录：

where: {[Op.not]: [ { complement: '""' }, ] },

在 Rails 中，它相当于 where.not(complement: '') - 如何在 nodejs 中包含带有否定 where 查询的记录？

这是我的完整文件：

'use strict'
let users = {};
const { BlockedUsers, LanguagesUsers, ProSettings, Users, UserReviews, GroupMeetingsReviews, GroupMeetings, Languages } = require('../models');
let models = require("../models/index");

let Sequelize = require('sequelize');
let Op = Sequelize.Op;
let sequelizeDB = require('../modules/Sequelize');


users.getProfileByUserId = (req, res) => {
    models.Users.findOne({
      where: {id: req.params.userid},
      include: [
        {
          model: models.UserReviews,
          as: 'complements',
        },
        {
          model: models.GroupMeetingsReviews,
          where: {
            'complement': {[Op.ne]: ''}
          },
          as: 'groupComplements',
          include: [
            {
              model: models.Users,
              as: 'reviewee',
              attributes: ['id', 'avatar_file_name', 'first_name']
            },
            {
              model: models.Users,
              as: 'reviewer',
              attributes: ['id', 'avatar_file_name', 'first_name']
            },
            {
              model: models.GroupMeetings,
              as: 'group_meeting',
            },
          ]
        },
      ],
    }).then(user => {
        models.sequelize
          .query(
            "SELECT languages_users.level, languages_users.language_id, languages.native, languages.locale, languages.flag, languages.language FROM languages_users JOIN languages ON languages_users.language_id = languages.id WHERE languages_users.user_id = ? ORDER BY level DESC",
            {
              replacements: [req.params.userid],
              type: models.PushToken.sequelize.QueryTypes.SELECT
            }
        )
        .then(languages => {
            user["encrypted_password"] = null;
            res.status(200).json({ status: 200, data: { user, languages } });
        });
    })
    .catch(error => {
        res.status(500).json({ status: 500, err: error });
    });
};

根据以下建议

model: models.GroupMeetingsReviews,
as: 'groupComplements',
where: {
  complement: {
    [Op.ne]: '',
  },
},

Answer 1

要获得complement 不是'' 或NULL 的结果，请使用以下语法：

model: models.GroupMeetingsReviews,
as: 'groupComplements',
where: {
  complement: {
    [Op.ne]: '',
    [Op.ne]: null,
  },
},
required: true,

您还可以将logging: true 添加到您的查询中，以通过console.log() 查看生成的SQL 以进行额外的调试。
