i have a few entities. Each entity includes many optional documents defined in the inherited BaseEntity.
public class Address : BaseEntity
{
public virtual Address Parent { get; set; }
public string Name1 { get; set; }
public string Name2 { get; set; }
public string Additional { get; set; }
public string Street { get; set; }
public string HousNr { get; set; }
public string ZipCode { get; set; }
public string City { get; set; }
public virtual Document Image { get; set; }
public virtual ICollection<AddressContact> AddressContacts { get; set; }
public virtual ICollection<Address> AddressPersons { get; set; }
}
public abstract class BaseEntity
{
public Guid Id { get; set; }
public bool IsDeleted { get; set; }
public bool IsSystem { get; set; }
public bool IsActive { get; set; }
public virtual ICollection<Document> Documents { get; set; }
public DateTime CreatedTime { get; set; }
public string CreatedUser { get; set; }
public DateTime? LastModifiedTime { get; set; }
public string LastModifiedUser { get; set; }
}
and my Document-Entity:
public class Document : BaseEntity
{
public string Filename { get; set; }
public string MIMEType { get; set; }
public int? Length { get; set; }
public byte[] Content { get; set; }
}
and here my base mapping:
public abstract class BaseEntityConfiguration<TEntity> : EntityTypeConfiguration<TEntity> where TEntity : BaseEntity
{
public abstract string TableName { get; }
public virtual bool HasDocument { get {return false;} }
public BaseEntityConfiguration()
{
HasKey(x => x.Id);
Property(x => x.CreatedUser).IsRequired().HasMaxLength(100);
if (HasDocument)
{
//TODO: general-Mapping for Documents??
}
else
{
Ignore(x => x.Documents);
}
ToTable(TableName);
}
}
how can i define my code-first-mapping, so that in the end only one general document table for all comming entities exists?

Patient.cs //This is Patient Model Class
namespace HMS.Models

[Key]
public string Id { get; set; }
public string Name { get; set; }

public DateTime DateOfDischarge { get; set; }
public int Advance { get; set; }
public string LabNo { get; set; }

Here Patient and InPatient Attribute have one-to-one relationship
ViewInPatient.cs

}
Here is my DbContext class
public class ApplicationDbContext:DbContext
{
public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options):base(options)
{
}
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
modelBuilder.Entity<DoctorPatient>()
.HasOne(x => x.Doctor)
.WithMany(dp => dp.DoctorPatients)
.HasForeignKey(di => di.DoctorId);
modelBuilder.Entity<DoctorPatient>()
.HasOne(y => y.Patient)
.WithMany(dp => dp.DoctorPatients)
.HasForeignKey(pi => pi.PatientId);
}
public DbSet<Patient> Patients { get; set; }
public DbSet<Doctor> Doctors { get; set; }
public DbSet<DoctorPatient> DoctorPatients { get; set; }
public DbSet<InPatient> InPatients { get; set; }
//public DbQuery<ViewInPatient> ViewInPatients { get; set; }
}
How to get all data of both Patients and InPatients Table like in ViewInPatient class? (I tried to create a view in sql server but in add table window it shows InPatient instead of InPatients and it return null value)
You can join both models in a Linq expression and return ViewInPatient list:
var ViewInPatient_set =
YourContext
.InPatients
.Select(i=> new ViewInPatient()
{
Name = i.Patient.Name,
// ...
RoomNo = i.RoomNo,
// ...
}
)
.ToList(); // <-- transform to list is optional
I have a table Users:
I am using Entity Framework 6 to make the type configuration
public class UsersMapping : EntityTypeConfiguration<Users>
{
public UsersMapping()
{
HasKey(t => t.UserID);
Property(t => t.UserID).IsRequired();
ToTable("Users", "dbo");
Property(t => t.Id).HasColumnName("UserID");
}
}
and this is the Users class:
public class Users : EntityBase
{
public int UserID { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string UserName { get; set; }
public DateTime DateCreated { get; set; }
public byte[] Timestamp { get; set; }
public byte[] Password { get; set; }
public DateTime? DateActivated { get; set; }
public bool LockedOut { get; set; }
public string Address { get; set; }
public string City { get; set; }
public int? State { get; set; }
public string Zip { get; set; }
public string SecurityQuestion { get; set; }
public string SecurityAnswer { get; set; }
public string Email { get; set; }
public string PhoneNumber { get; set; }
public bool? ReportServiceAccount { get; set; }
public string CompanyName { get; set; }
public int? ILAC { get; set; }
public string BioFingerprint { get; set; }
public string Title { get; set; }
public string Squad { get; set; }
public byte[] SignatureFile { get; set; }
public byte? CETGroupID { get; set; }
public string TokenID { get; set; }
public int? Pin { get; set; }
public string RadioNr { get; set; }
}
public class EntityBase
{
public int Id { get; set; }
}
I am trying to set the Id field as primary because my repository pattern works using the field Id that is not present on this case in the table. But when I am trying to get the set of users I get this error:
The column name is invalid UserID1
The weird thing to me is the #1 that is at the end. What I am doing wrong?
I have many to many relationship tables such as "User & Notification & UserNotification" and their entities, view models also.
There is only a difference between ViewModel and Entity classes. HasRead property is inside NotificationViewModel. How Can I map this entities to view models? I could not achieve this for HasRead property.
What I did so far is,
Mapping Configuration:
CreateMap<Notification, NotificationViewModel>();
CreateMap<User, UserViewModel>().ForMember(dest => dest.Notifications, map => map.MapFrom(src => src.UserNotification.Select(x => x.Notification)));
Notification class:
public class Notification : IEntityBase
{
public Notification()
{
this.UserNotification = new HashSet<UserNotification>();
}
public int Id { get; set; }
public string Header { get; set; }
public string Content { get; set; }
public System.DateTime CreateTime { get; set; }
public bool Status { get; set; }
public virtual ICollection<UserNotification> UserNotification { get; set; }
}
User Class
public class User : IEntityBase
{
public User()
{
this.UserNotification = new HashSet<UserNotification>();
}
public int Id { get; set; }
public string Name { get; set; }
public string Surname { get; set; }
public string Email { get; set; }
public string PhoneNumber { get; set; }
public bool Status { get; set; }
public virtual ICollection<UserNotification> UserNotification { get; set; }
}
UserNotification class:
public class UserNotification : IEntityBase
{
public int Id { get; set; }
public int UserId { get; set; }
public int NotificationId { get; set; }
public bool HasRead { get; set; }
public virtual Notification Notification { get; set; }
public virtual User User { get; set; }
}
UserViewModel class
public class UserViewModel : IValidatableObject
{
public int Id { get; set; }
public string Name { get; set; }
public string Surname { get; set; }
public string Email { get; set; }
public string PhoneNumber { get; set; }
public bool Status { get; set; }
public IList<NotificationViewModel> Notifications { get; set; }
}
NotificationViewModel class
public class NotificationViewModel
{
public int Id { get; set; }
public string Header { get; set; }
public string Content { get; set; }
public System.DateTime CreateTime { get; set; }
public bool Status { get; set; }
public bool HasRead { get; set; } // this is the difference
}
In order to fix up the HasRead, maybe you can utilize the AfterMap(Action<TSource, TDestination> afterFunction) function. It's not as elegant as the rest of automapper, but it might work.
CreateMap<User, UserViewModel>()
.ForMember(dest => dest.Notifications, map => map.MapFrom(src => src.UserNotification.Select(x => x.Notification)))
.AfterMap((src, dest) =>
{
foreach (var notificationVM in dest.Notifications)
{
notificationVM.HasRead = src.UserNotification.Where(x => x.NotificationId == notificationVM.Id).Select(x => x.HasRead).FirstOrDefault();
}
});
Here are my models:
public partial class NEWS
{
public NEWS()
{
}
[Key]
public int NEWSID { get; set; }
public string Title { get; set; }
public string Text { get; set; }
public string InsertDate { get; set; }
public int GroupingID { get; set; }
public virtual Subjects Subjects { get; set; }
}
public partial class Subjects
{
public Subjects()
{ this.NEWSs = new HashSet<NEWS>(); }
[Key]
public int GroupingID { get; set; }
public string Farsi { get; set; }
public string Latin { get; set; }
public virtual ICollection<NEWS> NEWSs { get; set; }
}
public class UserGroup
{
public UserGroup()
{ this.Userss = new HashSet<Users>(); }
[Key]
public int UserID { get; set; }
public string Title { get; set; }
public virtual ICollection<Users> Userss { get; set; }
}
public class Users
{
public Users()
{ }
public string Name { get; set; }
public string Family { get; set; }
public string Email { get; set; }
public string UserName { get; set; }
public string PassWord { get; set; }
[Key]
public int UserID { get; set; }
public virtual UserGroup UserGroup { get; set; }
// public HashSet<Users> Userss { get; set; }
}
public class NEWSDBContext : DbContext
{
public NEWSDBContext()
: base()
{
Database.SetInitializer<NEWSDBContext>(null);
}
public DbSet<NEWS> NEWSs { get; set; }
public DbSet<Users> Userss { get; set; }
public DbSet<UserGroup> UserGroups { get; set; }
public DbSet<Subjects> Subjectss { get; set; }
}
I always get an error in return View(newss.ToList());:
The underlying provider failed on Open
I am trying to use AutoMapper to map a ViewModel to a Model.
Here is my simplified ViewModel (the source) class:
public class EditPaypointVM
{
public Int64 Id { get; set; }
public Int64 OrganisationId { get; set; }
[Required]
public string OrganisationContactNumber { get; set; }
public Int64 PostalAddressId { get; set; }
public string PostalAddressAddressText { get; set; }
[Required]
public Int64 PostalAddressArea { get; set; }
public string PostalAddressAreaText { get; set; }
public string PostalAddressCode { get; set; }
public Int64 PhysicalAddressId { get; set; }
public string PhysicalAddressAddressText { get; set; }
[Required]
public Int64 PhysicalAddressArea { get; set; }
public string PhysicalAddressAreaText { get; set; }
public string PhysicalAddressCode { get; set; }
}
Here is my simplified Model (destination) class:
public class Paypoint
{
public Int64 Id { get; set; }
public virtual Organisation Organisation { get; set; }
public virtual Employer Employer { get; set; }
public virtual List<EmploymentContract> EmploymentContracts { get; set; }
public bool IsActive { get; set; }
}
public class Organisation
{
public Int64 Id { get; set; }
public virtual List<EmailAddress> EmailAdresses { get; set; }
public virtual List<ContactNumber> ContactNumbers { get; set; }
public virtual List<Address> Adresses { get; set; }
public string RegisteredName { get; set; }
public string TradingName { get; set; }
public string RegistrationNumber { get; set; }
public string WebsiteAddress { get; set; }
}
Here is the code I execute to create mappings in memory on application start:
Mapper.CreateMap<EditPaypointVM, Paypoint>()
.ForMember(dest => dest.IsActive,
opt => opt.UseValue(true))
.ForMember(dest => dest.Organisation,
opt => opt.UseDestinationValue())
.Ignore(i => i.Employer)
.Ignore(i => i.EmploymentContracts);
Upon executing 'AssertConfigurationIsvalid' within a unit test, an "Unmapped error is thrown which states that the Organisation member of Paypoint is unmapped.
Any ideas on what causes this?
