validateIntegrity method

  1. @override
VerificationContext validateIntegrity(
  1. Insertable<Student> instance, {
  2. bool isInserting = false,
})
override

Validates that the given entity can be inserted into this table, meaning that it respects all constraints (nullability, text length, etc.).

Implementation

@override
VerificationContext validateIntegrity(
  Insertable<Student> instance, {
  bool isInserting = false,
}) {
  final context = VerificationContext();
  final data = instance.toColumns(true);
  if (data.containsKey('id')) {
    context.handle(_idMeta, id.isAcceptableOrUnknown(data['id']!, _idMeta));
  }
  if (data.containsKey('student_id')) {
    context.handle(
      _studentIdMeta,
      studentId.isAcceptableOrUnknown(data['student_id']!, _studentIdMeta),
    );
  } else if (isInserting) {
    context.missing(_studentIdMeta);
  }
  if (data.containsKey('name')) {
    context.handle(
      _nameMeta,
      name.isAcceptableOrUnknown(data['name']!, _nameMeta),
    );
  }
  return context;
}
