I am taking over a project from a guy. They did a great job and claim that this coded worked. I can't get it to work and search through the forums trying to figure out how to fix it.
We are using SQL 2005 and NHibernate 1.2
AftermarketOption.HBM

The classes that these HBM files reference.
AftermarketOption.cs
Code:
public class AftermarketOption : DomainObject<Int64> {
private string _name;
private int _order;
private IList<AftermarketOptionProduct> _products;
private decimal _price;
private string _displayColor;
#region List Properties
public virtual List<AftermarketOptionProduct> xProducts {
get { return new List<AftermarketOptionProduct>(_products); }
set { _products = value; }
}
public virtual string DisplayColor {
get { return _displayColor; }
set { _displayColor = value; }
}
public virtual string Name {
get { return _name; }
set { _name = value; }
}
public virtual int DisplayOrder {
get { return _order; }
set { _order = value; }
}
public virtual IList<AftermarketOptionProduct> Products {
get { return _products; }
}
public virtual decimal Price {
get { return _price; }
set { _price = value; }
}
public AftermarketOption() {
_products = new List<AftermarketOptionProduct>();
}
}
AftermarketProduct.cs
Code:
public class AftermarketProduct : DomainObject<Int64>{
private string _displayName;
private string _longDescription;
private string _shortDescription;
private decimal _price;
private decimal _dealerCost;
public virtual decimal DealerCost {
get { return _dealerCost; }
set { _dealerCost = value; }
}
public virtual string DisplayName {
get { return _displayName; }
set { _displayName = value; }
}
public virtual string LongDescription {
get { return _longDescription; }
set { _longDescription = value; }
}
public virtual decimal Price {
get { return _price; }
set { _price = value; }
}
public virtual string ShortDescription {
get { return _shortDescription; }
set { _shortDescription = value; }
}
}
AftermarketOptionProduct.cs
Code:
public class AftermarketOptionProduct : AftermarketProduct {
private int _displayOrder;
private AftermarketOption _option;
public virtual int DisplayOrder {
get { return _displayOrder; }
set { _displayOrder = value; }
}
public virtual AftermarketOption Option {
get { return _option; }
set { _option = value; }
}
public AftermarketOptionProduct() { }
public AftermarketOptionProduct(AftermarketProduct ap) {
this.DealerCost = ap.DealerCost;
this.DisplayName = ap.DisplayName;
this.LongDescription = ap.LongDescription;
this.Price = ap.Price;
this.ShortDescription = ap.ShortDescription;
}
public AftermarketOptionProduct(AftermarketProduct ap, int displayOrder): this(ap) {
this._displayOrder = displayOrder;
}
}
Here is the test code I am using to test the mappings.
Code:
IList<AftermarketProduct> products = DaoFactory.GetAftermarketProduct().GetAll();
AftermarketOption ao = new AftermarketOption();
ao.DisplayColor = "Blue";
ao.DisplayOrder = 1;
ao.Name = "AftermarketOption 1";
ao.Price = 1234;
for (int i = 0; i < products.Count; i++) {
AftermarketOptionProduct aop = new AftermarketOptionProduct(products[i], i+1);
aop.Option = ao;
aop.Index = products[i].Index;
ao.Products.Add(aop);
}
DaoFactory.GetAftermarketOptionDao().SaveOrUpdate(ap);
Here is the tables that I have that I am using:
Code:
CREATE TABLE AftermarketProducts
(
ProductIndex bigint NOT NULL IDENTITY (1, 1),
Code varchar(10) NULL,
ShortDesc varchar(100) NULL,
Details text NULL,
PriceAmount money NULL,
DealerCost money NULL
) ON [PRIMARY]
go
ALTER TABLE AftermarketProducts ADD CONSTRAINT
PK_ProductIndex PRIMARY KEY CLUSTERED
(
ProductIndex
) WITH( PAD_INDEX = OFF, FILLFACTOR = 90, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
go
CREATE TABLE AftermarketOptions
(
OptionIndex bigint NOT NULL IDENTITY (1, 1),
OptionName varchar(50) NOT NULL,
OptionPrice money NULL,
DisplayOrder bigint NULL,
DisplayColor varchar(6) NULL
) ON [PRIMARY]
go
ALTER TABLE AftermarketOptions ADD CONSTRAINT
PK_OptionIndex PRIMARY KEY CLUSTERED
(
OptionIndex
) WITH( PAD_INDEX = OFF, FILLFACTOR = 90, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
go
CREATE TABLE AftermarketOptionProducts

) ON [PRIMARY]
go
ALTER TABLE AftermarketOptionProducts ADD CONSTRAINT
FK_AftermarketOptionProducts_AftermarketOptionIndex FOREIGN KEY
(
AftermarketOptionIndex
) REFERENCES AftermarketOptions
(
OptionIndex
) ON UPDATE NO ACTION
ON DELETE NO ACTION
go
ALTER TABLE AftermarketOptionProducts ADD CONSTRAINT
FK_AftermarketOptionProducts_AftermarketProductIndex FOREIGN KEY
(
AftermarketProductIndex
) REFERENCES AftermarketProducts
(

ON DELETE NO ACTION
go
ALTER TABLE AftermarketOptionProducts ADD CONSTRAINT

AftermarketOptionIndex
) WITH( PAD_INDEX = OFF, FILLFACTOR = 90, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
go
This issue I am having is that the AftermarketOption has a list of products that are extended AftermarketProducts only with an order. I will continue to look into this but I haven't found anything that helps yet. I am hoping there is someone in the communitiy that can help.
For a while I was getting that NonUniqueObjectExecption error because I was getting a list of the products first. The products have already been created and are going to be in multiple AftermarketOptions. I solved that by clearing the session. In the log it saves the AftermarketOption correctly but as soon as it tries to add the products it dies and rolls back.
Am I missing something obvious or is this even possible?
Thanks for all the help in advance.
I am willing to do whatever it takes to get this to work.
