Question

Trying to map a Order Class with two identical sub classes and Getting the following error

Could not find a getter for property 'RatingCriteria1' in class 'ORM.Entities.Enquiry.EnquiryOrder'

Basically I have one table in database with alot of columns. 12 columns are rating related

BuyerRatingCriteria1,BuyerRatingCriteria2, BuyerRatingCriteria3, BuyerRatingCriteria4, BuyerRatingCriteria5, BuyerRatingCriteriaComments

And

SupplierRatingCriteria1, SupplierRatingCriteria2, SupplierRatingCriteria3, SupplierRatingCriteria4, SupplierRatingCriteria5, SupplierRatingCriteriaComments

I want to simplify these into two subclasses on the so that i have

Order.SupplierRating.Criteria1

and

Order.BuyerRating.Criteria1

for example

public class EnquiryOrder : Entity
{
    public virtual int Id { get; set; }
    public virtual DateTime DateOrdered { get; set; }

    public virtual string PONumber { get; set; }
    public virtual string SONumber { get; set; }

    public virtual Rating SupplierRatings { get; set; }
    public virtual Rating BuyerRatings { get; set; }

}

public class Rating : Entity
{
    public virtual int RatingCriteria1 { get; set; }
    public virtual int RatingCriteria2 { get; set; }
    public virtual int RatingCriteria3 { get; set; }
    public virtual int RatingCriteria4 { get; set; }
    public virtual int RatingCriteria5 { get; set; }
    public virtual string RatingCriteriaComment { get; set; }

}

Mapping I thought would be as easy as this

    public EnquiryOrderMapping()
    {
        Id(x => x.Id).Column("EnquiryOrderId");
        Map(x => x.DateOrdered);

        Map(x => x.PONumber).Nullable();
        Map(x => x.SONumber).Nullable();

        Map(x => x.BuyerRatings.RatingCriteria1).Column("EnquiryBuyerRatingsRatingCriteria1").Nullable();
        Map(x => x.BuyerRatings.RatingCriteria2).Column("EnquiryBuyerRatingsRatingCriteria2").Nullable();
        Map(x => x.BuyerRatings.RatingCriteria3).Column("EnquiryBuyerRatingsRatingCriteria3").Nullable();
        Map(x => x.BuyerRatings.RatingCriteria4).Column("EnquiryBuyerRatingsRatingCriteria4").Nullable();
        Map(x => x.BuyerRatings.RatingCriteria5).Column("EnquiryBuyerRatingsRatingCriteria5").Nullable();
        Map(x => x.BuyerRatings.RatingCriteriaComment).Column("EnquiryBuyerRatingsRatingCriteriaComment").Nullable();

    }

No I have left out mapping the supplier side here as I was trying to simplify it best I could to be able to solve it.

So I don’t understand why its having a issue… I’ve told it which column to look at (full name) not “RatingCriteria1”

as well as when I do have a variable RatingCriteria1 it has a getter and setter!!!

very odd… am i missing something you have to do when mapping sub classes like this?

You need to map Ratings as a component, by doing:

public EnquiryOrderMapping()
{
    Id(x => x.Id).Column("EnquiryOrderId");
    Map(x => x.DateOrdered);

    Map(x => x.PONumber).Nullable();
    Map(x => x.SONumber).Nullable();

    Component(x => x.BuyerRatings,
        y => 
            {
                y.Map(r => r.RatingCriteria1, "EnquiryBuyerRatingsRatingCriteria1").Nullable();
                y.Map(r => r.RatingCriteria2, "EnquiryBuyerRatingsRatingCriteria2").Nullable();
                y.Map(r => r.RatingCriteria3, "EnquiryBuyerRatingsRatingCriteria3").Nullable();
                // etc..
            });     
    // etc..
}
