My models are :
**Organization**
const Organization = sequelize.define('Organization', {
org_name: DataTypes.STRING
}, {});
Organization.associate = function(models) {
Organization.hasMany(models.User,{ through: 'User_Roles'});
Organization.hasMany(models.Department ,{ through: 'User_Roles'});
};
**Department**
const Department = sequelize.define('Department', {
name: DataTypes.STRING
}, {});
Department.associate = function(models) {
Department.belongsTo(models.Organization);
};
**user**
const User = sequelize.define('User', {
username: DataTypes.STRING,
}, {});
User.associate = function(models) {
User.belongsToMany(models.Organization,{ through: 'User_Roles'});
User.belongsToMany(models.Department,{ through: 'User_Roles'});
User.belongsToMany(models.Role,{ through: 'User_Roles'});
};
**role**
const Role = sequelize.define('Role', {
role_name: DataTypes.STRING
}, {});
Role.associate = function(models) {
Role.belongsToMany(models.User,{ through: 'User_Roles'});
};
