I added sequelizeInstance while define model
*models/Ticket.js
const { DataTypes, Model } = require('sequelize');
const sequelizeInstance = require('./database');
module.exports = class Tickets extends Model {
static init(sequelize) {
return super.init( {
ticketId: {
type: DataTypes.INTEGER,
autoIncrement: true,
primaryKey: true,
},
channelId: {
type: DataTypes.STRING,
},
guildId: {
type: DataTypes.STRING,
},
resolved:{
type: DataTypes.BOOLEAN,
},
closedMessageId:{
type: DataTypes.STRING,
},
authorId:{
type: DataTypes.STRING,
},
},
{
sequelize: sequelizeInstance, // <-
modelName: 'Ticket'
})
}
}
models/TicketConfig.js
const { DataTypes, Model } = require('sequelize');
const sequelizeInstance = require('./database')
module.exports = class TicketConfig extends Model {
static init(sequelize) {
return super.init({
messegeId: {
type: DataTypes.STRING,
primaryKey: true
},
guildld: {
type: DataTypes.STRING
},
roles: {
type: DataTypes.STRING
},
parentld: {
type: DataTypes.STRING
},
sequelize: sequelizeInstance, // <-
modelName: 'TicketConfig',
})
}
}
