validateIntegrity method

@override VerificationContext validateIntegrity(Insertable<Migration> instance, { bool isInserting = false, })

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<Migration> 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('name')) {
    context.handle(
        _nameMeta, name.isAcceptableOrUnknown(data['name']!, _nameMeta));
  } else if (isInserting) {
    context.missing(_nameMeta);
  }
  context.handle(_migrationStateMeta, const VerificationResult.success());
  if (data.containsKey('start')) {
    context.handle(
        _startMeta, start.isAcceptableOrUnknown(data['start']!, _startMeta));
  }
  if (data.containsKey('finish')) {
    context.handle(_finishMeta,
        finish.isAcceptableOrUnknown(data['finish']!, _finishMeta));
  }
  return context;
}
