validateIntegrity method

  1. @override
VerificationContext validateIntegrity(
  1. Insertable<ChatItemRow> 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<ChatItemRow> instance,
    {bool isInserting = false}) {
  final context = VerificationContext();
  final data = instance.toColumns(true);
  if (data.containsKey('id')) {
    context.handle(_idMeta, id.isAcceptableOrUnknown(data['id']!, _idMeta));
  } else if (isInserting) {
    context.missing(_idMeta);
  }
  if (data.containsKey('chat_id')) {
    context.handle(_chatIdMeta,
        chatId.isAcceptableOrUnknown(data['chat_id']!, _chatIdMeta));
  } else if (isInserting) {
    context.missing(_chatIdMeta);
  }
  if (data.containsKey('author_id')) {
    context.handle(_authorIdMeta,
        authorId.isAcceptableOrUnknown(data['author_id']!, _authorIdMeta));
  } else if (isInserting) {
    context.missing(_authorIdMeta);
  }
  context.handle(_atMeta, const VerificationResult.success());
  context.handle(_statusMeta, const VerificationResult.success());
  if (data.containsKey('data')) {
    context.handle(
        _dataMeta, this.data.isAcceptableOrUnknown(data['data']!, _dataMeta));
  } else if (isInserting) {
    context.missing(_dataMeta);
  }
  if (data.containsKey('cursor')) {
    context.handle(_cursorMeta,
        cursor.isAcceptableOrUnknown(data['cursor']!, _cursorMeta));
  }
  if (data.containsKey('ver')) {
    context.handle(
        _verMeta, ver.isAcceptableOrUnknown(data['ver']!, _verMeta));
  } else if (isInserting) {
    context.missing(_verMeta);
  }
  return context;
