Javascript 续集计数关联记录

我有一个帖子和一个评论模型，它们是关联的。一篇文章有很多评论，一篇评论属于一篇文章

后模型

class Post extends Model {
  static init(sequelize) {
    super.init(
      {
        description: {
          type: DataTypes.STRING,
          allowNull: false,
          validate: {
            notEmpty: {
              args: true,
              msg: "A description is required",
            },
          },
        },
        createdAt: {
          type: DataTypes.DATE,
          allowNull: false,
          field: "created_at",
        },
        updatedAt: {
          type: DataTypes.DATE,
          allowNull: false,
          field: "updated_at",
        },
      },
      { sequelize }
    );

    return this;
  }

  static associate(models) {
    this.belongsTo(models.User, { foreignKey: "userId" });
    this.hasMany(models.PostPhoto, { foreignKey: "postId" });
    this.hasMany(models.Comment, { foreignKey: "postId" });
    this.hasMany(models.Like, { foreignKey: "postId" });
  }
}

注释模型

class Comment extends Model {
  static init(sequelize) {
    super.init(
      {
        comment: {
          type: DataTypes.STRING,
          allowNull: false,
          validate: {
            notEmpty: {
              args: true,
              msg: "A comment is required",
            },
          },
        },
        createdAt: {
          type: DataTypes.DATE,
          allowNull: false,
          field: "created_at",
        },
        updatedAt: {
          type: DataTypes.DATE,
          allowNull: false,
          field: "updated_at",
        },
      },
      { sequelize }
    );

    return this;
  }

  static associate(models) {
    this.belongsTo(models.Post, { foreignKey: "postId" });
    this.belongsTo(models.User, { foreignKey: "userId" });
  }
}

我试图查找所有帖子，并统计每篇帖子中的评论数。我尝试了下面显示的查询，但它只检索一条记录，并且计数加倍

const posts = await Post.findAll({
   order: [["createdAt", "DESC"]],
   attributes: {
      exclude: ["updatedAt"],
      include: [
        [Sequelize.fn("COUNT", Sequelize.col("comment")), "commentCount"],
      ],
   },
   include: [
      {
        model: Like,
      },
      {
        model: Comment,
        attributes: [],
      },
   ],
});
