How to get data from related table with sequelize

I want to collect data using model sequelize mysql.

For the master data, i have Model ReviewFormModel. Here is the code

class ReviewFormModel {

  constructor(sequelizeClient, DataTypes) {
    this.sequelize = sequelizeClient;
    this.dataTypes = DataTypes;
  }

  getReviewForm() {
    const reviewFormModel = this.sequelize.define('reviewFormModel', {
      name: this.dataTypes.TEXT,
      type: this.dataTypes.TEXT,
      min_value: this.dataTypes.TEXT,
      max_value: this.dataTypes.TEXT,
    }, {
      tableName: 'review_form',
      underscored: true,
    });

    return reviewFormModel;
  }
}

module.exports = ReviewFormModel;

That model has many ReviewFormDetail. Here is the model.

class ReviewFormDetailModel {

  constructor(sequelizeClient, DataTypes) {
    this.sequelize = sequelizeClient;
    this.dataTypes = DataTypes;
  }

  getReviewFormDetail() {
    const reviewFormDetailModel = this.sequelize.define('reviewFormDetailModel', {
      parent_id: this.dataTypes.INTEGER,
      label: this.dataTypes.TEXT,
      trans_id: this.dataTypes.TEXT,
    }, {
      tableName: 'review_form_detail',
      underscored: true,
    });

    return reviewFormDetailModel;
  }
}

module.exports = ReviewFormDetailModel;

For collect the data i am using code like this. But i get error. Here is the code i used to collect the data.

this.reviewDetailModel.getReviewFormDetail().belongsTo(this.reviewModel.getReviewForm(), {
        foreignKey: 'parent_id', as: 'ReviewForm',
      });
      this.reviewDetailModel.getReviewFormDetail()
          .findAll({ include: [{
            model: this.reviewModel.getReviewForm(),
            as: 'ReviewForm' }] })
          .then((results) => {
            console.log(results);
          })
          .then((res) => {
            resolve(res);
          });

But I get error like this

Unhandled rejection Error: reviewFormModel (ReviewForm) is not associated to reviewFormDetailModel!
