How to define an array in my models using mysql sequelize | node.js - mysql

Question

This is the result what I need to store in DB :
sellers : [{'test1'},{'test2'},{'test3'}]
And this is my model:
module.exports = (sequelize, DataTypes) => {
const User = sequelize.define(
"User",
{
id: {
allowNull: false,
primaryKey: true,
autoIncrement: true,
type: DataTypes.INTEGER,
},
name: {
type: DataTypes.STRING,
allowNull: false,
},
email: {
type: DataTypes.STRING,
allowNull: false,
unique: true,
},
password: {
type: DataTypes.STRING,
allowNull: false,
},
sellers: [
{
type: DataTypes.STRING,
allowNull: true,
},
],
},
{
timestamps: true,
defaultScope: {
attributes: {
exclude: ["password"],
},
},
scopes: {
withPassword: {
attributes: {},
},
},
indexes: [
{
unique: true,
fields: ["email"],
},
],
}
);
return User;
};
And the error is :
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near

Answer 1

sellers: [
{
type: DataTypes.ARRAY(DataTypes.STRING),
allowNull: true,
}

Answer 2

You need to slightly change your schema definition as,
sellers: {
type: DataTypes.ARRAY(DataTypes.JSON),
allowNull: true,
defaultValue: [{}],
get() {
const data = this.getDataValue('sellers');
const queryResponse = [];
data.forEach(seller => {
queryResponse.push(JSON.parse(seller));
});
return queryResponse;
},
set(seller) {
return this.setDataValue('sellers', JSON.stringify(seller));
}
},
