TypeError: Cannot create property 'hooks' on string ???

During fetch from User model I got this

options.hooks = options.hooks === undefined ? false : Boolean(options.hooks);
                  ^

TypeError: Cannot create property 'hooks' on string 'food_id'

My User Models:

'use strict';
module.exports = (sequelize, DataTypes) => {
  const User = sequelize.define('User', {
    name: DataTypes.STRING,
    address: DataTypes.STRING,
    phone: DataTypes.STRING,
    email: DataTypes.STRING,
    password: DataTypes.STRING,
  }, {
    tableName: 'users'
  });
  User.associate = function(models) {
    User.belongsToMany(models.Role, { through: 'user_role', foreignKey: 'user_id', otherKey: 'role_id' });
    User.hasMany(models.Order, 'user_id');
    User.hasMany(models.Food, 'canteen_manager_id');
  };
  return User;
};

Food Model:

'use strict';
module.exports = (sequelize, DataTypes) => {
  const Food = sequelize.define('Food', {
    title: DataTypes.STRING,
    price: DataTypes.FLOAT,
    quantity: DataTypes.SMALLINT,
    description: DataTypes.STRING,
    canteen_manager_id: DataTypes.INTEGER
  }, {
    tableName: 'foods'
  });
  Food.associate = function(models) {
    Food.belongsTo(models.User, 'canteen_manager_id');
  };
  return Food;
};

Constraint:

'use strict';

module.exports = {
  up: (queryInterface, Sequelize) => {
    return queryInterface.addConstraint('foods', ['canteen_manager_id'], {
      type: 'foreign key',
      name: 'fk_canteen_manager_id',
      references: {
        table: 'users',
        field: 'id'
      },
      onDelete: 'cascade',
      onUpdate: 'cascade'
    });
  },

  down: (queryInterface, Sequelize) => {
    return queryInterface.removeConstraint('foods', 'fk_canteen_manager_id');
  }
};

Oh, you can’t pass a string as the second argument to belongsTo, you probably meant to use { as: <string> }.

@rabin999 you are free to create a PR to improve the documentation as you see fit, PRs are welcome. I also suggest you may switch to TS as it will help you avoid these types of simple mistakes from the get go.
