How can I trigger the beforeCreate hook when bulkCreating in Sequelize?

Question

I have a beforeCreate hook in a Sequelize model (runs bcrypt on the password in a User table), and would like to create a user in the seed file. Functions like bulkCreate simply insert into the database, and so don't call any hooks (including the createdAt/updatedAt). How do I create with the hooks called in a way that matches the format required by the seeder?

It seems like many are just using sequelize-fixtures? Is this the way to go? Or I could just ignore the seed format, and use the standard .create/.build and .save format?

Also, where is documentation related to seeding located? The Google searches were pretty light in terms of info.

Set the individualHooks option to true when bulkCreating, as below:

User.bulkCreate(users, {individualHooks: true}).then(function() {
  console.log("Done!");
});

There's some documentation about this option here.

Also, if you're allowing users to change passwords, you should add a beforeUpdate hook as well. You can prevent the password from being processed by bcrypt two times (when properties of the User other than the password are updated) in the following way:

function hashPassword(user, options, fn) {
  //Don't hash if password is already hashed
  if (user.dataValues.password.indexOf('$2a$') === 0) {
    fn(null, user);
    return;
  }

  bcrypt.hash(user.password, 10, function(err, hash) {
    if (err) {
      console.log('Error while generating hash!');
      fn(err, null);
      return;
    }
    user.password = hash;
    fn(null, user);
  });
}
