Question

我正在使用sails.js和sequelize.js ORM。这就是我如何定义模型以使用关联： https://github.com/KSDaemon/sails-hook-sequelize

模型用户：

module.exports = {
  attributes: {
    user_id: {
      type: Sequelize.INTEGER,
      primaryKey: true,
      autoIncrement: true
    },
    username: Sequelize.STRING,
    password: Sequelize.STRING,
    createdAt: Sequelize.DATE,
  },
  associations: function () {
    Response.hasMany(Post, { as: 'posts', foreignKey: 'user_id' });
    Response.hasMany(Response, { as: 'responses', foreignKey: 'user_id' });
  },
  defaultScope: function () {
    return {
      include: [
        { model: Post, as: 'posts' },
        { model: Response, as: 'responses' },
      ]
    };
  },
  options: {
    freezeTableName : false,
    tableName       : 'users',
    schema          : 'codigomx',
    classMethods    : {},
    instanceMethods : {},
    hooks           : {}
  }
};

和我的模特回应：

module.exports = {

  attributes: {
    response_id: {
      type: Sequelize.INTEGER,
      primaryKey: true,
      autoIncrement: true
    },
    response_content: Sequelize.TEXT,
    createdAt: Sequelize.DATE
  },
  associations: function () {
    Response.belongsTo(User, { foreignKey: 'user_id', targetKey: 'user_id'});
    Response.belongsTo(Post, { foreignKey: 'post_id', targetKey: 'post_id'});
  },
  options: {
    freezeTableName : false,
    tableName       : 'responses',
    schema          : 'codigomx',
    classMethods    : {},
    instanceMethods : {},
    hooks           : {}
  }

};

但是当我尝试运行时：

User.findOrCreate({where: {username: 'user'}, defaults: {password: 'psw'}});

它给了我这个错误：未处理的拒绝SequelizeEagerLoadingError：响应与用户没有关联！

我确实有正确的关联，有人可以告诉我，如果我的协会有问题吗？

Answer 1

我认为用户模型中存在拼写错误。

而不是Response.hasMany(Post, { as: 'posts', foreignKey: 'user_id' });，应该是User.hasMany(Post, { as: 'posts', foreignKey: 'user_id' });

未处理的拒绝SequelizeEagerLoadingError：modalB与modelA无关
