validateIntegrity method

  1. @override
VerificationContext validateIntegrity(
  1. Insertable<Syllabus> 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<Syllabus> 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('course_offering')) {
    context.handle(
      _courseOfferingMeta,
      courseOffering.isAcceptableOrUnknown(
        data['course_offering']!,
        _courseOfferingMeta,
      ),
    );
  } else if (isInserting) {
    context.missing(_courseOfferingMeta);
  }
  if (data.containsKey('teacher')) {
    context.handle(
      _teacherMeta,
      teacher.isAcceptableOrUnknown(data['teacher']!, _teacherMeta),
    );
  } else if (isInserting) {
    context.missing(_teacherMeta);
  }
  if (data.containsKey('updated_at')) {
    context.handle(
      _updatedAtMeta,
      updatedAt.isAcceptableOrUnknown(data['updated_at']!, _updatedAtMeta),
    );
  }
  if (data.containsKey('fetched_at')) {
    context.handle(
      _fetchedAtMeta,
      fetchedAt.isAcceptableOrUnknown(data['fetched_at']!, _fetchedAtMeta),
    );
  } else if (isInserting) {
    context.missing(_fetchedAtMeta);
  }
  return context;
