Empty string as acceptable value on non-optional field? about meteor-simple-schema HOT 2 CLOSED

I ran into the same corner case, where I have a non-optional string which is allowed to be empty.

Polite complain +1.

Yes, an empty string fails required validation by design. If there are enough complaints, this could be changed, but I think it generally makes sense. To make it allow an empty string but not null or undefined, you could use optional: true along with a custom function similar to this:

function () {
  if (!this.operator && this.value == null) {
    return "required";
  }
}
