If you are using id_buyer
to create the relationsip between Payment
and Buyer
you'll need to save ret
first.

i have a class library in c# and entity framework that has a payment model.
My payment model have one table called Payment
, and then another table called PaymentSolid
, this last one saves the solid values of the first one like if the first one have IdSeller
, then the seccond one have SellerName
.
My question is that i have a method called NewPayment
where i create the Payment
entity and the PaymentSolid
.
I have the next code in my method:
Payment ret;
using (var context = new MyEntities())
{
ret = new Payment
{
id_buyer = IdBuyer,
id_seller = IdSeller,
id_seller_bill_to = IdSellerBillTo,
id_payment_method = IdPaymentMethod,
creation_date = CreationDate,
payment_status = PaymentStatus,
notes = Notes
};
context.Payments.AddObject(ret);
context.Refresh(RefreshMode.StoreWins, ret);
var retSolid = new PaymentSolid {
buyer_name = ret.Buyer.ProviderName,
seller_name = ret.Seller.ProviderName,
seller_bill_to_name = ret.SellerBillTo != null ? ret.SellerBillTo.ProviderName : null,
payment_method_name = ret.PaymentMethod.name
};
ret.PaymentSolid = retSolid;
context.SaveChanges();
context.Refresh(RefreshMode.StoreWins, ret);
}
return ret;
}
And my question is if i can use the ret.Buyer.ProviderName
to create the solid or if i have to save the Payment
first to then create the solid.
