sails checks for required before the beforeCreate method on creation

[hassench]

Hi,

I can't find the logic of verifying if a field is undefined when it's marked as required, before the beforeCreate!
Example:
reference: {type: 'string', columnType: 'string', columnName: "reference", required: true},
then

self.beforeCreate = function (values, next) {
  values.reference = sails.helpers.generateRandomString();
  next();
};

Here I'm generating the reference in beforeCreate, which is logical. I should create a reference only here, it's simply a unique random string. So I'm sure that it will always be there.

But I have an error saying the reference is undefined while it's required, when I'm trying to create a new record of my model.

Of course when I remove required: true everything is fine, but that's not what I want.

The logical sequence is to check for undefined and do all the validations AFTER the beforeCreate function.
