ENUM Sequelize Error

Question

I get the error RangeError: Maximum call stack size exceeded in my model statement. Follow code below:

const { Model, DataTypes } = require('sequelize')

class Usuario extends Model {
    static init(sequelize) {
        Usuario.init({
            nome: DataTypes.STRING,
            nascimento: DataTypes.DATE,
            genero: DataTypes.ENUM('masculino', 'feminino'),
            email: DataTypes.STRING,
            disponibilidade: DataTypes.ENUM('presencial', 'online'),
            biografia: DataTypes.STRING,
            foto_perfil: DataTypes.STRING
        }, {sequelize})
    } 
}

module.exports = Usuario;

The error message:

C:\Users\helde\Documents\TCC\node_modules\sequelize\lib\data-types.js:739
  constructor(...args) {
             ^

Answer 1

This mistake happens because you are calling .init() in class Usuario recursively on Usuario.init(...), then it enters and infinite loop and generates this error.

The mistake has nothing to do with ENUM, keep the type code as is.

The right thing would be for you to call super.init(), that is to start the Model and not the class itself Usuario.

Try this way:

class Usuario extends Model {
    static init(sequelize) {
        super.init({
            nome: DataTypes.STRING,
            nascimento: DataTypes.DATE,
            genero: DataTypes.ENUM('masculino', 'feminino'),
            email: DataTypes.STRING,
            disponibilidade: DataTypes.ENUM('presencial', 'online'),
            biografia: DataTypes.STRING,
            foto_perfil: DataTypes.STRING
        }, {sequelize})
    } 
}

Answer 2

    class Usuario extends Model {
    static init(sequelize) {
        super.init({
            nome: DataTypes.STRING,
            nascimento: DataTypes.DATE,
            genero: DataTypes.ENUM('masculino', 'feminino'),
            email: DataTypes.STRING,
            disponibilidade: DataTypes.ENUM('presencial', 'online'),
            biografia: DataTypes.STRING,
            foto_perfil: DataTypes.STRING,
            senha: DataTypes.STRING
        },  { sequelize ,
             tableName: 'usuario' },
        )
    }
}

error was solved by adding the tableName property: 'user'
