I am having a problem with Fluent and Entity Framework.
To start, I created a new database project and used Reverse Engineer Code First to generate a set of Models and Maps.
If I look at the tables in the existing database, I have a table called Parcel and a table called ParcelAgremment.
When I look at the mappings for the two tables I see:
public class ParcelMap : EntityTypeConfiguration<Parcel>
{
public ParcelMap()
{
// Primary Key
this.HasKey(t => t.ParcelId);
// Properties
this.Property(t => t.ParcelReference)
.IsRequired()
.HasMaxLength(20);
this.Property(t => t.ParcelDescription)
.HasMaxLength(1000);
// Table & Column Mappings
this.ToTable("Parcel");
this.Property(t => t.ParcelId).HasColumnName("ParcelId");
this.Property(t => t.SiteId).HasColumnName("SiteId");
this.Property(t => t.ParentParcelId).HasColumnName("ParentParcelId");
this.Property(t => t.IsCurrent).HasColumnName("IsCurrent");
this.Property(t => t.ParcelTypeId).HasColumnName("ParcelTypeId");
this.Property(t => t.ParcelReference).HasColumnName("ParcelReference");
this.Property(t => t.ParcelDescription).HasColumnName("ParcelDescription");
// Relationships
this.HasOptional(t => t.Parcel2)
.WithMany(t => t.Parcel1)
.HasForeignKey(d => d.ParentParcelId);
this.HasRequired(t => t.ParcelType)
.WithMany(t => t.Parcels)
.HasForeignKey(d => d.ParcelTypeId);
this.HasRequired(t => t.Site)
.WithMany(t => t.Parcels)
.HasForeignKey(d => d.SiteId);
}
}
public class ParcelAgreementMap : EntityTypeConfiguration<ParcelAgreement>
{
public ParcelAgreementMap()
{
// Primary Key
this.HasKey(t => t.ParcelAgreementId);
// Properties
// Table & Column Mappings
this.ToTable("ParcelAgreement");
this.Property(t => t.ParcelAgreementId).HasColumnName("ParcelAgreementId");
this.Property(t => t.ParcelId).HasColumnName("ParcelId");
this.Property(t => t.AgreementTypeId).HasColumnName("AgreementTypeId");
this.Property(t => t.RightsChecked).HasColumnName("RightsChecked");
this.Property(t => t.OptionRightsTypeId).HasColumnName("OptionRightsTypeId");
this.Property(t => t.AgreementDate).HasColumnName("AgreementDate");
this.Property(t => t.AgreementNotes).HasColumnName("AgreementNotes");
this.Property(t => t.ConditionsChecked).HasColumnName("ConditionsChecked");
this.Property(t => t.IsAssignable).HasColumnName("IsAssignable");
// Relationships
this.HasOptional(t => t.OptionRightsType).WithMany(t => t.ParcelAgreements).HasForeignKey(d => d.OptionRightsTypeId);
this.HasRequired(t => t.AgreementType).WithMany(t => t.ParcelAgreements).HasForeignKey(d => d.AgreementTypeId);
this.HasRequired(t => t.Parcel).WithMany(t => t.ParcelAgreements).HasForeignKey(d => d.ParcelId);
}
}
and the model files are:
public class Parcel : Entity
{
public Parcel()
{
this.LandTransactionElements = new List<LandTransactionElement>();
this.Parcel1 = new List<Parcel>();
this.ParcelAgreements = new List<ParcelAgreement>();
this.ParcelDeedPackets = new List<ParcelDeedPacket>();
this.ParcelExceptions = new List<ParcelException>();
this.ParcelFinancialTemplates = new List<ParcelFinancialTemplate>();
this.ParcelNote = new List<ParcelNote>();
this.ParcelOptions = new List<ParcelOption>();
this.ParcelReferences = new List<ParcelReference>();
this.ParcelRentPayments = new List<ParcelRentPayment>();
this.ParcelRights = new List<ParcelRight>();
this.ParcelStampDuties = new List<ParcelStampDuty>();
this.ParcelVolumes = new List<ParcelVolume>();
this.ReviewPlans = new List<ReviewPlan>();
}
public int ParcelId { get; set; }
public int SiteId { get; set; }
public Nullable<int> ParentParcelId { get; set; }
public bool IsCurrent { get; set; }
public int ParcelTypeId { get; set; }
public string ParcelReference { get; set; }
public string ParcelDescription { get; set; }
public virtual ICollection<LandTransactionElement> LandTransactionElements { get; set; }
public virtual ICollection<Parcel> Parcel1 { get; set; }
public virtual Parcel Parcel2 { get; set; }
public virtual ParcelType ParcelType { get; set; }
public virtual Site Site { get; set; }
public virtual ICollection<ParcelAgreement> ParcelAgreements { get; set; }
public virtual ICollection<ParcelDeedPacket> ParcelDeedPackets { get; set; }
public virtual ICollection<ParcelException> ParcelExceptions { get; set; }
public virtual ICollection<ParcelFinancialTemplate> ParcelFinancialTemplates { get; set; }
public virtual ICollection<ParcelNote> ParcelNote { get; set; }
public virtual ICollection<ParcelOption> ParcelOptions { get; set; }
public virtual ICollection<ParcelReference> ParcelReferences { get; set; }
public virtual ICollection<ParcelRentPayment> ParcelRentPayments { get; set; }
public virtual ICollection<ParcelRight> ParcelRights { get; set; }
public virtual ICollection<ParcelStampDuty> ParcelStampDuties { get; set; }
public virtual ICollection<ParcelVolume> ParcelVolumes { get; set; }
public virtual ICollection<ReviewPlan> ReviewPlans { get; set; }
}
}
public class ParcelAgreement : Entity
{
public int ParcelAgreementId { get; set; }
public int ParcelId { get; set; }
public int AgreementTypeId { get; set; }
public bool RightsChecked { get; set; }
public Nullable<int> OptionRightsTypeId { get; set; }
public Nullable<System.DateTime> AgreementDate { get; set; }
public string AgreementNotes { get; set; }
public Nullable<bool> ConditionsChecked { get; set; }
public Nullable<bool> IsAssignable { get; set; }
public virtual AgreementType AgreementType { get; set; }
public virtual OptionRightsType OptionRightsType { get; set; }
public virtual Parcel Parcel { get; set; }
}
I am calling the database using
var retData = parcelRepository
.Query(s=> s.ParcelId == optionId)
.Select()
.ToList();
The query works, but when I try to access the ParcelAgreement object from the Parecl object I get following error
InnerException {"Invalid object name 'dbo.ParcelAgreements'."} System.Exception {System.Data.SqlClient.SqlException}
The table is called ParcelAgreement not ParcelAgreements in the database.
If check the project by using a global search for ParcelAgreements, it returns nothing found.
I have other tables that are linked which also does not have a plural table name and it is recovering the data fine.
As per request: Update
In my context file.
public DbSet<Parcel> Parcels { get; set; }
public DbSet<ParcelAgreement> ParcelAgreements { get; set; }
And in the OnModelCreating sub.
modelBuilder.Configurations.Add(new ParcelMap());
modelBuilder.Configurations.Add(new ParcelAgreementMap());
Update 11th May
After looking around it appears that the fix is to add
modelBuilder.Conventions.Remove<PluralizingEntitySetNameConvention>();
to OnModelCreating. As per Link to SO article
unfortunatley this also does not work.
My code looks like
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
modelBuilder.Configurations.Add(new ActivityMap());
...
... <List of other table>
}
On running I still get the error:
{"Invalid object name 'dbo.ActivityMaps'."} System.Exception {System.Data.SqlClient.SqlException}
As you can see it is still trying to pluralize the table name.
I am using EF 6.0.0.0
