How do I define a unique index on a combination of columns in sequelize. For example I want to add a unique index on user_id, count and name.
var Tag = sequelize.define('Tag', {
id: {
type: DataTypes.INTEGER(11),
allowNull: false,
primaryKey: true,
autoIncrement: true
},
user_id: {
type: DataTypes.INTEGER(11),
allowNull: false,
},
count: {
type: DataTypes.INTEGER(11),
allowNull: true
},
name: {
type: DataTypes.STRING,
allowNull: true,
})
