javascript - Sequelize 包含范围为 1 :m constraint = false 的对象

Question

我想对其他表格使用相同的表格 Photo。 我阅读了 Sequelize 文档 here 他们使用范围并像这样设置 constraint = false

const Comment = this.sequelize.define('comment', {
  title: Sequelize.STRING,
  commentable: Sequelize.STRING,
  commentable_id: Sequelize.INTEGER
});

Comment.prototype.getItem = function(options) {
  return this['get' + this.get('commentable').substr(0, 1).toUpperCase() + this.get('commentable').substr(1)](options);
};

Post.hasMany(this.Comment, {
  foreignKey: 'commentable_id',
  constraints: false,
  scope: {
    commentable: 'post'
  }
});
Comment.belongsTo(this.Post, {
  foreignKey: 'commentable_id',
  constraints: false,
  as: 'post'
});

我的问题是:我如何查询包含每个帖子的列表评论的帖子列表(如果可用则有限制)。 谢谢。

Answer 1

HOW I can query list of Post that include list comments for each post

来，试试这个

Post
  .find({
    where: { /* include where condition if you have or remove this */ },
    include: [{
      model: Comment,
      as: 'comments',
    }],
  })
  .then(function(result) {
    // check result.dataValues. it should contain `comments` array
  });

我想这个限制还不可用。检查此更新 https://github.com/sequelize/sequelize/issues/1897
