validateIntegrity method

  1. @override
VerificationContext validateIntegrity(
  1. Insertable<ChatItemViewRow> 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<ChatItemViewRow> instance, {
  bool isInserting = false,
}) {
  final context = VerificationContext();
  final data = instance.toColumns(true);
  if (data.containsKey('chat_id')) {
    context.handle(
      _chatIdMeta,
      chatId.isAcceptableOrUnknown(data['chat_id']!, _chatIdMeta),
    );
  } else if (isInserting) {
    context.missing(_chatIdMeta);
  }
  if (data.containsKey('chat_item_id')) {
    context.handle(
      _chatItemIdMeta,
      chatItemId.isAcceptableOrUnknown(
        data['chat_item_id']!,
        _chatItemIdMeta,
      ),
    );
  } else if (isInserting) {
    context.missing(_chatItemIdMeta);
  }
  return context;
}
