Sequelize Eager Loading Error when including related model

Question

I\'m using Sequelize to make this request:

return Expense.findAll({
     include: [{
       model: ExpenseCategory
     }],
   })
  .then(expenses => res.stat         


        

Answer 1

Just change this sections

classMethods: {
    associate: function (models) {
        ExpenseCateogory.hasMany(models.Expense, {
            foreignKey: 'expenseCategoryId'
        });
    }
}

to

ExpenseCategory.associate = (models) => {
    ExpenseCategory.hasMany(models.style,{
        as:'expensecategories'
    });
}

so the model in full will follow this structure and the other models as well

const ExpenseCategory = sequelize.define('ExpenseCategory', {
    id: {
        allowNull: false,
        autoIncrement: true,
        primaryKey: true,
        type: DataTypes.INTEGER
    },
    category: {
        allowNull: false,
        type: DataTypes.STRING
    }
});
ExpenseCategory.associate = (models) => {
    ExpenseCategory.hasMany(models.style,{
        as:'expensecategories'
    });
}
return ExpenseCategory;
