Seeding ARRAY(ENUM)

Issue Description

I am trying to seed an ARRAY(ENUM), but I have not been able to figure out how to do so. I also haven’t been able to find any other issue/documentation that showed how to do this.

I keep getting this error: ERROR: column "roles" is of type "enum_Users_roles"[] but expression is of type text[]

This is my migration script:

return queryInterface.createTable('Users', {
     id: {
        allowNull: false,
        autoIncrement: true,
        primaryKey: true,
        type: Sequelize.INTEGER
      },  

      email: {
        type: Sequelize.STRING,
	      allowNull: false
      },  

      password: {
        type: Sequelize.STRING,
	      allowNull: false
      },  

      roles: {
        type: Sequelize.ARRAY(Sequelize.ENUM({
	        values: ['user', 'setter', 'admin']
        })),
	      allowNull: false
      },  

      public_id: {
        type: Sequelize.UUID,
	      defaultValue: Sequelize.UUIDV4,
	      allowNull: false
      },  

      createdAt: {
        allowNull: false,
        type: Sequelize.DATE
      },  

      updatedAt: {
        allowNull: false,
        type: Sequelize.DATE
      }  
    })

And here is my seed file:

'use strict';
const faker = require('faker');

module.exports = {
  up: async (queryInterface, Sequelize) => {
	  return queryInterface.bulkInsert('Users', [
		  {
			  email: faker.internet.email(),
			  roles: ['user'],
			  password: "hash",
			  public_id: faker.random.uuid(),
			  created_at: new Date(),
			  updated_at: new Date()
		  }
	  ]);
  },

  down: (queryInterface, Sequelize) => {

    return queryInterface.bulkDelete('Users', null, {});
  }
};

StackOverflow / Slack attempts

I asked on StackOverflow, but I have not gotten any response (it has only been a day) https://stackoverflow.com/questions/58326145/sequelize-seeding-arrayenum

@papb sorry. Didn’t mean to close it on you. The stackoverflow question got a some views and a few thumbs up, so I guess I am not the only one trying to figure it out. Probably a good call to add it to docs. Thanks

You can use this code

class Item extends Sequelize.Model { }

Item.init({
  name: { type: DataTypes.STRING },
  values: {
    type: DataTypes.ARRAY(DataTypes.ENUM({
      values: ['a', 'b']
    }))
  }
}, {
  sequelize,
  timestamps: true
})

sequelize.sync({ force: true }).then(async () => {
  await sequelize.queryInterface.bulkInsert('Items', [
    {
      name: 'xyz',
      values: sequelize.literal(`ARRAY['a']::"enum_Items_values"[]`),
      createdAt: new Date(),
      updatedAt: new Date()
    }
  ]);
});

Executing (default): INSERT INTO "Items" ("name","values","createdAt","updatedAt") VALUES ('xyz',ARRAY['a']::"enum_Items_values"[],'2019-10-16 16:44:30.953 +00:00','2019-10-16 16:44:30.953 +00:00');
