validateIntegrity method

@override VerificationContext validateIntegrity(Insertable<LanguageData> 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<LanguageData> 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('name')) {
    context.handle(
      _nameMeta,
      name.isAcceptableOrUnknown(data['name']!, _nameMeta),
    );
  } else if (isInserting) {
    context.missing(_nameMeta);
  }
  if (data.containsKey('name_in_english')) {
    context.handle(
      _nameInEnglishMeta,
      nameInEnglish.isAcceptableOrUnknown(
        data['name_in_english']!,
        _nameInEnglishMeta,
      ),
    );
  } else if (isInserting) {
    context.missing(_nameInEnglishMeta);
  }
  if (data.containsKey('seq_num')) {
    context.handle(
      _seqNumMeta,
      seqNum.isAcceptableOrUnknown(data['seq_num']!, _seqNumMeta),
    );
  } else if (isInserting) {
    context.missing(_seqNumMeta);
  }
  return context;
