I have three classes UserProfile, Groups and Contacts. I want to
delete a Group without deleting its Contacts. GroupID in Contacts table
should be set to null when the Group is deleted. What to do?
The three classes:
[Table("UserProfile")]
public class UserProfile
{
[Key]
[DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)]
public int UserId { get; set; }
public string UserName { get; set; }
public virtual ICollection<Groups> Groups { get; set; }
public virtual ICollection<Contacts> Contacts { get; set; }
}
public class Groups
{
[Key, DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int GroupID { get; set; }
[Required]
public string GroupName { get; set; }
public string Description { get; set; }
[ForeignKey("User")]
public int UserID { get; set; }
[DatabaseGenerated(DatabaseGeneratedOption.Computed)]
public DateTime? CreateDate { get; set; }
[DatabaseGenerated(DatabaseGeneratedOption.Computed)]
public DateTime? ModifiedDate { get; set; }
public virtual UserProfile User { get; set; }
public virtual ICollection<Contacts> Contacts { get; set; }
}
public class Contacts
{
[Key, DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int ContactID { get; set; }
[ForeignKey("Group")]
public int? GroupID { get; set; }
[ForeignKey("User")]
public int UserID { get; set; }
public Prefix? Prefix { get; set; }
[Required]
public string FirstName { get; set; }
[Required]
public string LastName { get; set; }
[Required]
[DataType(DataType.Date)]
public DateTime? BirthDate { get; set; }
[DatabaseGenerated(DatabaseGeneratedOption.Computed)]
public DateTime? CreateDate { get; set; }
[DatabaseGenerated(DatabaseGeneratedOption.Computed)]
public DateTime? ModifiedDate { get; set; }
public virtual UserProfile User { get; set; }
public virtual Groups Group { get; set; }
public virtual ICollection<Groups> Groups { get; set; }

I need some help displaying the name instead of a GUID inside a DataTable in MVC 5.
I implemented the DataTable by following this tutorial: https://www.c-sharpcorner.com/article/ajax-crud-operation-with-jquery-datatables-in-asp-net-mvc-5-for-beginners/
I am trying to show the names for a Municipal Region, Municipality and Client Status. It shows perfectly fine inside my details view model, however it displays the GUID in the DataTable. I have spent days trying to figure this out to no avail.
Here is the code for the DataTable in my controller:
public ActionResult Get([ModelBinder(typeof(DataTablesBinder))] IDataTablesRequest requestModel, ClientsAdvancedSearchViewModel searchViewModel)
{
IQueryable<Client> query = DbContext.Clients;
var totalCount = query.Count();
// searching and sorting
query = SearchClients(requestModel, searchViewModel, query);
var filteredCount = query.Count();
// Paging
query = query.Skip(requestModel.Start).Take(requestModel.Length);
var data = query.Select(client => new
{
ClientIdentifier = client.ClientIdentifier,
CompanyName = client.CompanyName,
ClientContactPerson = client.ClientContactPerson,
ClientEmail = client.ClientEmail,
ClientTel = client.ClientTel,
Consultant = client.Consultant,
Town = client.Town,
Suburb = client.Suburb,
MunicipalRegionID = client.MunicipalRegionID,
MunicipalityID = client.MunicipalityID,
ClientStatusID = client.ClientStatusID,
}).ToList();
return Json(new DataTablesResponse(requestModel.Draw, data, filteredCount, totalCount), JsonRequestBehavior.AllowGet);
}
And here is the code for my client class:
public class Client
{
[Key]
public System.Guid ClientIdentifier { get; set; }
public string CompanyName { get; set; }
public string SiteName { get; set; }
public string Status { get; set; }
public string Consultant { get; set; }
public string Comments { get; set; }
[DataType(DataType.Date)]
[DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = true)]
public Nullable<System.DateTime> Date { get; set; }
public string ClientInformation { get; set; }
public string ClientContactPerson { get; set; }
public string ClientEmail { get; set; }
public string ClientTel { get; set; }
public string ClientAddress { get; set; }
public string GPSCoordinates { get; set; }
public string Town { get; set; }
public string Suburb { get; set; }
public System.Guid MunicipalRegionID { get; set; }
public System.Guid MunicipalityID { get; set; }
public System.Guid ClientStatusID { get; set; }
public string CreatedBy { get; set; }
public Nullable<System.DateTime> DateCreated { get; set; }
public string LastEditedBy { get; set; }
public Nullable<System.DateTime> DateLastEdited { get; set; }
}
Here is the code for my Municipal Region Class:
public class MunicipalRegion
{
[Key]
public System.Guid MunicipalRegionIdentifier { get; set; }
public string MunicipalRegionName { get; set; }
public string CreatedBy { get; set; }
public Nullable<System.DateTime> DateCreated { get; set; }
public string LastEditedBy { get; set; }
public Nullable<System.DateTime> DateLastEdited { get; set; }
}
Here is the code for my Municipality Class:
public class Municipality
{
[Key]
public System.Guid MunicipalityIdentifier { get; set; }
public string MunicipalityName { get; set; }
public System.Guid MunicipalRegionID { get; set; }
public string CreatedBy { get; set; }
public Nullable<System.DateTime> DateCreated { get; set; }
public string LastEditedBy { get; set; }
public Nullable<System.DateTime> DateLastEdited { get; set; }
Here is the code for my Client Status Class:
public class ClientStatus
{
[Key]
public System.Guid ClientStatusIdentifier { get; set; }
public string ClientStatusName { get; set; }
public string CreatedBy { get; set; }
public Nullable<System.DateTime> DateCreated { get; set; }
public string LastEditedBy { get; set; }
public Nullable<System.DateTime> DateLastEdited { get; set; }
}
Help would be appreciated. Thank you :)
I may be wrong but it sounds like you are trying to hide the key fields from generated views. This can be accomplished adding the following annotation.
[Display(AutoGenerateField=false)]
Ok, I see what you are trying to do now. The main problem is your classes are not set up correctly. From a database perspective they are correct but from a class perspective, they won't return what you want.
You need to set up your classes as follows
Client Class
public Client()
{
Municipality = new Municipality();
Status = new ClientStatus();
}
[Key]
public System.Guid ClientIdentifier { get; set; }
public string CompanyName { get; set; }
public string SiteName { get; set; }
public string Consultant { get; set; }
public string Comments { get; set; }
[DataType(DataType.Date)]
[DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = true)]
public Nullable<System.DateTime> Date { get; set; }
public string ClientInformation { get; set; }
public string ClientContactPerson { get; set; }
public string ClientEmail { get; set; }
public string ClientTel { get; set; }
public string ClientAddress { get; set; }
public string GPSCoordinates { get; set; }
public string Town { get; set; }
public string Suburb { get; set; }
public string CreatedBy { get; set; }
public Nullable<System.DateTime> DateCreated { get; set; }
public string LastEditedBy { get; set; }
public Nullable<System.DateTime> DateLastEdited { get; set; }
// Create Forign Key Connections
public Municipality Municipality { get; set; }
public ClientStatus Status { get; set; }
}
Municipality Class
public class Municipality
{
public Municipality() {
MunicipalRegion = new MunicipalRegion();
}
[Key]
public System.Guid MunicipalityIdentifier {
get;
set;
}
public string MunicipalityName { get; set; }
public string CreatedBy { get; set; }
public Nullable<System.DateTime> DateCreated { get; set; }
public string LastEditedBy { get; set; }
public Nullable<System.DateTime> DateLastEdited { get; set; }
public MunicipalRegion MunicipalRegion { get; set; }
}
This will allow you to produce output using something similar to
var data = clients.Select(cl => new
{
ClientIdentifier = cl.ClientIdentifier,
CompanyName = cl.CompanyName,
MunicipalRegion = cl.Municipality.MunicipalityName,
Status = cl.Status.ClientStatusName
});
I have two objects, Project is a DB entity and IProject which I am trying to save to the database:
public interface IProject
{
int ProjectID { get; set; }
string JobNumber { get; set; }
string JobName { get; set; }
string ProjectLocation { get; set; }
int? FeeTypeID { get; set; }
decimal? Fee { get; set; }
decimal? ConstructionCost { get; set; }
decimal? CostPerSquareFoot { get; set; }
decimal? SquareFoot { get; set; }
string Memo { get; set; }
DateTime? DateCompleted { get; set; }
int JobStatusID { get; set; }
int ProjectTypeID { get; set; }
}
//The inheritance is actually in a partial class that doesn't get overridden
public partial class Project : IProject
{
public Project()
{
this.ProjectContacts = new HashSet<ProjectContact>();
this.ProjectConsultants = new HashSet<ProjectConsultant>();
}
public int ProjectID { get; set; }
public string JobNumber { get; set; }
public string JobName { get; set; }
public Nullable<int> FeeTypeID { get; set; }
public Nullable<decimal> Fee { get; set; }
public int JobStatusID { get; set; }
public string Memo { get; set; }
public Nullable<decimal> Acreage { get; set; }
public Nullable<decimal> SquareFoot { get; set; }
public Nullable<decimal> ConstructionCost { get; set; }
public Nullable<decimal> BudgetPrice { get; set; }
public Nullable<decimal> ActualPrice { get; set; }
public Nullable<System.DateTime> DateCompleted { get; set; }
public Nullable<decimal> CostPerSquareFoot { get; set; }
public string ProjectLocation { get; set; }
public int ProjectTypeID { get; set; }
public Nullable<System.DateTime> StartDate { get; set; }
public Nullable<int> PhaseID { get; set; }
public string ProjectDescription { get; set; }
public Nullable<int> ArchitectID { get; set; }
public Nullable<int> ManagerID { get; set; }
public Nullable<int> ArchiveLocationID { get; set; }
public virtual ICollection<ProjectContact> ProjectContacts { get; set; }
public virtual FeeType FeeType { get; set; }
public virtual JobStatu JobStatu { get; set; }
public virtual ICollection<ProjectConsultant> ProjectConsultants { get; set; }
public virtual Person Person { get; set; }
public virtual ArchiveLocation ArchiveLocation { get; set; }
public virtual Person Person1 { get; set; }
public virtual Phase Phase { get; set; }
public virtual ProjectType ProjectType { get; set; }
}
I have my Map created:
Mapper.CreateMap<IProject, Data.Project>();
but for some reason whenever I call the map:
//mappingService is a wrapper I have around Automapper so that I can inject it
var project = _mappingService.Map<IProject, Data.Project>(request);
I get this error:
Missing type map configuration or unsupported mapping.
Mapping types:
RuntimeType -> FeeType
System.RuntimeType -> Renaissance.Data.FeeType
Destination path:
Project.FeeType.FeeType
Source value:
System.Decimal
I am not at any point trying to do that. The names match and even if I specifically tell it to map with:
.ForMember(dest => dest.Fee, opt => opt.MapFrom(src => src.Fee))
It still errors with the same message.
What am I missing?
UPDATE
This works:
.ForMember(dest => dest.FeeType, opt => opt.Ignore());
I think it is a hack that I need to do that. I shouldn't have to ignore a property in the destination that does not exist / is not named the same as something in the source property.
I am modeling a service business that performs multiple services at each visit to a client. I have a Visit table, a Service table and a link table, VisitService. I am using this Request DTO in my service to get a list of services for a visit:
[Route("/visits/{visitid}/services", Verbs = "GET")]
public class ServicesAtVisit : QueryBase<VisitService, ServiceAtVisit>, IJoin<VisitService, My.Namespace.Service> {
public int VisitId { get; set; }
}
ServiceAtVisit is a custom DTO that I'm projecting into.
Because one of my DTOs is a class with the unfortunate name "Service", I have to fully-qualify it in the IJoin because, otherwise, it is ambiguous with ServiceStack.Service. Now, when I hit the route, I get the error "Could not infer relationship between VisitService and Service".
The interesting thing is that I've got this working with other many-to-many relationships (Client.AssignedStaffMembers, StaffMember.AssignedClients for the tables Client -> ClientStaffMember -> StaffMember) and I can't see anything different.
Is the problem the name of my DTO and the fact that I'm having to fully-qualify it?
Visit:
[Route("/visits", Verbs = "POST")]
public partial class Visit {
[AutoIncrement]
public long Id { get; set; }
public int ServiceRequestId { get; set; }
public string TimeOfDay { get; set; }
public DateTime Date { get; set; }
public TimeSpan? PreferredStartTime { get; set; }
public TimeSpan? PreferredEndTime { get; set; }
public bool IsFirstVisit { get; set; }
public bool IsLastVisit { get; set; }
public bool IncursWeekendFee { get; set; }
public bool WaiveWeekendFee { get; set; }
public bool IncursHolidayFee { get; set; }
public bool WaiveHolidayFee { get; set; }
public bool IncursLastMinuteSchedulingFee { get; set; }
public bool WaiveLastMinuteSchedulingFee { get; set; }
public bool IncursLastMinuteCancellationFee { get; set; }
public bool WaiveLastMinuteCancellationFee { get; set; }
public int? StaffMemberId { get; set; }

}
VisitService:
public partial class VisitService {
// Workaround for composite key limitation
public string Id {
get {
return this.VisitId.ToString() + "|" + this.ServiceId.ToString();
}
}
public long VisitId { get; set; }
public int ServiceId { get; set; }
public int Quantity { get; set; }
public bool FeeIsWaived { get; set; }
[Ignore]
public Visit Visit { get; set; }
[Ignore]
public Service Service { get; set; }
}
Service:
public partial class Service {
[AutoIncrement]
public int Id { get; set; }
public int ServiceTypeId { get; set; }
public string Name { get; set; }
public string Description { get; set; }
public int DisplayOrder { get; set; }
public bool IsHourly { get; set; }
public bool IsMonthly { get; set; }
[Ignore]
public ServiceType ServiceType { get; set; }
[Ignore]
public ServicePrice CurrentPrice { get; set; }
}
Projecting results into ServiceAtVisit:
public partial class ServiceAtVisit {
public int ServiceTypeId { get; set; }
public string Name { get; set; }
public string Description { get; set; }
public int DisplayOrder { get; set; }
public bool IsHourly { get; set; }
public bool IsMonthly { get; set; }
public int VisitId { get; set; }
public int ServiceId { get; set; }
public int Quantity { get; set; }
public bool FeeIsWaived { get; set; }
}
I've just tried creating an AutoQuery Service with all the types you've provided under a custom MyNamespace and it's working as expected (in the latest of ServiceStack), i.e:
Service definition:
namespace MyNamespace
{
[Route("/visits/{VisitId}/services", Verbs = "GET")]
public class ServicesAtVisit : QueryBase<VisitService, ServiceAtVisit>,
IJoin<VisitService, Service>

}
public partial class ServiceAtVisit

public string Name { get; set; }
public string Description { get; set; }
public int DisplayOrder { get; set; }
public bool IsHourly { get; set; }
public bool IsMonthly { get; set; }
public int VisitId { get; set; }
public int ServiceId { get; set; }
public int Quantity { get; set; }
public bool FeeIsWaived { get; set; }
}
}
Type definition:
namespace MyNamespace
{
[Route("/visits", Verbs = "POST")]

public DateTime Date { get; set; }
public TimeSpan? PreferredStartTime { get; set; }
public TimeSpan? PreferredEndTime { get; set; }

i want use name,family,customerid from tblcustomers
and productId,NameProduct,Price from tblProducts
and all fields of tblOrders and tblOrderList
how can i create one view to fill tables Orders and OrderList??
i solved problem like below article:
How to Use ViewModel with ASP.NET MVC ?
How to Use ValueInjecter with Asp.net MVC ViewModel ?
I'm trying to map the following entities:
public class Person
{
public int Id { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public Address Address { get; set; }
public DateTime DOB { get; set; }
public List<Telephone> Telephones { get; set; }
}
public class SearchPersonViewModel
{
public int Id { get; set; }
public string FullName { get; set; }
public string LicencePlate { get; set; }
public string CarMake { get; set; }
public string CarModel { get; set; }
}
I do that:
AutoMapper.Mapper.CreateMap<List<SearchPersonViewModel>, List<Person>>();
List<SearchPersonViewModel> model = AutoMapper.Mapper.Map<List<Person>, List<SearchPersonViewModel>>(persons);
And I get the exception 'Missing type map configuration or unsupported mapping.'
I don't see what's wrong with my code, anyone could help ?
