关系模型查询 Sequelize

Question

我有一个问题，关于如何在 NODEJS 中使用 SEQUELIZE 恢复另一个关系中的关系。

例如，在 Laravel PHP 中我可以这样做：

Model::with(['character.genetic'])->get()

这样会带来“Character”的关系以及“Character has with Genetic”的关系，但是在NODE中怎么做呢？

以下是我在 NodeJS 中的代码示例：

let data = await PlayerCharacter.findAll({
        include: ['character.genetic'], ///dont works
        where: {
          playerId: req.playerId,
        },
        order: [
          ['levelId', 'desc']
        ]
      });

我的班级主要

import Sequelize from 'sequelize';
import database from '../database';

const PlayerCharacter = database.define('player_characters', {
    .....
    characterId: {
        type: Sequelize.BIGINT,
        allowNull: false,
    },
    .....
});

/**
 * Relationships
 */

PlayerCharacter.belongsTo(Character, {
    foreignKey: 'characterId',
    as: 'character',
});

export default PlayerCharacter;

我的班级角色

import Sequelize from 'sequelize';
import database from '../database';

const Character = database.define('characters', {
    ...
    geneticId: {
        type: Sequelize.INTEGER,
        allowNull: false,
    },
   ....
}, {
    timestamps: false,
});

/**
 * Relationships
 */

Character.hasOne(CharacterGenetic, {
    foreignKey: 'geneticId',
    as: 'genetic',
});

export default Character;

您应该像这样使用嵌套的include 选项：

let data = await PlayerCharacter.findAll({
        include: [{
          model: Character,
          as: 'character',
          include: [{
            model: CharacterGenetic,
            as: 'genetic'
          }  
          ]
        }
        ],
        where: {
          playerId: req.playerId,
        },
        order: [
          ['levelId', 'desc']
        ]
      });
