validateIntegrity method

@override VerificationContext validateIntegrity(Insertable<SalesOrderLineData> 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<SalesOrderLineData> 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('sales_order_id')) {
    context.handle(
      _salesOrderIdMeta,
      salesOrderId.isAcceptableOrUnknown(
        data['sales_order_id']!,
        _salesOrderIdMeta,
      ),
    );
  } else if (isInserting) {
    context.missing(_salesOrderIdMeta);
  }
  if (data.containsKey('product_id')) {
    context.handle(
      _productIdMeta,
      productId.isAcceptableOrUnknown(data['product_id']!, _productIdMeta),
    );
  } else if (isInserting) {
    context.missing(_productIdMeta);
  }
  if (data.containsKey('units')) {
    context.handle(
      _unitsMeta,
      units.isAcceptableOrUnknown(data['units']!, _unitsMeta),
    );
  } else if (isInserting) {
    context.missing(_unitsMeta);
  }
  if (data.containsKey('amount')) {
    context.handle(
      _amountMeta,
      amount.isAcceptableOrUnknown(data['amount']!, _amountMeta),
    );
  } else if (isInserting) {
    context.missing(_amountMeta);
  }
  if (data.containsKey('tax_amount')) {
