I'm stuck on this question. Sequelize.STRING is obviously not sufficient, but adding on allowNull: false, validate with notNull/notEmpty is not working either. Feel as though I've tried everything. Help, please?
The question is: Complete the code below by adding the data type that prevents empty strings when creating a model instance:
Car.init({
Make: {
type: Sequelize.<FILL IN ANSWER>
},
}, { sequelize });

I guess I understand why you feel that STRING would not (or should not) be sufficient, but Sequelize.STRING is indeed the correct answer.
Yes, you would need to add validation. But the Datatype that would make that validation relevant to a string is STRING. Adding a notEmpty validation to a Sequelize.BOOLEAN datatype (for example) would do nothing with regards to strings (assuming that’s a valid validator for the BOOLEAN datatype). So even though Sequelize.STRING isn’t enough code to prevent your user from inputting an empty string, it is the only Datatype that prevents empty strings as it’s the only one that requires a string.
I hope that makes sense.
