I'm using EF5.0 (database first) and trying to Update "Company" entity which is a complex type, it contains "Address" entity as navigation property.
I receive a Company DTO object from UI and I map it, using AutoMapper, to Entity object and call objectContext.Save() for saving.
Problem am facing is, "Company" entity values are getting saved but not the "Address" entity. Below are the each object details-
public class CompanyDto
{
public int Id { get; set; }
public string Name { get; set; }
public AddressDto Address { get; set; }
}
with AddressDto as -
public class AddressDto : IDto
{
public int Id { get; set; }
public string Street { get; set; }
public string City { get; set; }
public string PostCode { get; set; }
}
Company Entity (generated by EF - database first)
public partial class tblCompany
{
public tblCompany()
{
this.tblAddresses = new HashSet<tblAddress>();
}
public int ID { get; set; }
public string CompanyName { get; set; }
public virtual ICollection<tblAddress> tblAddresses { get; set; } //navigation property
}
with Address entity is as follows -
public partial class tblAddress
{
public int ID { get; set; }
public int CaseID { get; set; }
public string AddressLine1 { get; set; }
public string AddressLine2 { get; set; }
public string City { get; set; }
public string County { get; set; }
public string PostCode { get; set; }
public virtual tblCase tblCase { get; set; }
}
AutoMapper mapping configuration for converting from DTO to entity
Mapper.CreateMap<CompanyDto, tblCase>()
.ForMember(x => x.ID, opt => opt.MapFrom(cd => cd.Id))
.ForMember(x => x.CompanyName, opt => opt.MapFrom(cd => cd.Name))
.AfterMap((s, d) => d.tblAddresses.Add(new tblAddress
{
AddressLine1 = s.Address.Street,
CaseID = s.Id,
City = s.Address.City,
PostCode = s.Address.PostCode
}));
public void Update(CompanyDto company)
{
//TO DO: check if AutoMapper could map address as well.
var companyDao = Mapper.Map<CompanyDto, tblCase>(company);
_companyRepository.Update(companyDao);
_unitOfWork.Save();
}
Thanks in advance

I have a DTO containing properties and a Model, eg student can have more than one module and a module can be associated with more than one student. the properties are mapping fine but the Model doesn't map.
public class GetStudentByIdMapping : Profile
{
public GetStudentByIdMapping()
{
CreateMap<Student,StudentDetails>();
CreateMap<Module, StudentDetails>()
.ForPath(dest => dest.StudentModules.ModuleName, opt => opt.MapFrom(m => m.ModuleName))
.ForPath(dest => dest.StudentModules.ModuleCode, opt => opt.MapFrom(m => m.ModuleCode))
.ForPath(dest => dest.StudentModules.Description, opt => opt.MapFrom(m => m.Description))
.ReverseMap();
}
}
public async Task<StudentDetails> GetStudent(int studentId)
{
var student = context.Student
.Where(s => s.StudentId == studentId)
.FirstOrDefault();
var module = await context.Order
.Include(m => m.Module)
.Where(o => o.StudentId == studentId)
.Select(m => m.Module).ToListAsync();
var studMap = Mapper.Map<StudentDetails>(student);
Mapper.Map<StudentDetails>(module);
return studMap;
}
These are the ViewModels I want to map to the Models Model in the StudentDetails ViewModel
public class StudentDetails
{
public string FirstName { get; set; }
public string LastName { get; set; }
public string Email { get; set; }
public string PhoneNumber { get; set; }
public StudentModule StudentModules { get; set; }
}
public class StudentModule
{
public string ModuleName { get; set; }
public string ModuleCode { get; set; }
public string Description { get; set; }
}
These are my Entities generated by EF Core
public partial class Student
{
public Student()
{
Order = new HashSet<Order>();
}
public int StudentId { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string Email { get; set; }
public string PhoneNumber { get; set; }
public string Username { get; set; }
public string Password { get; set; }
public virtual ICollection<Order> Order { get; set; }
}
public partial class Module
{
public Module()
{
Order = new HashSet<Order>();
}
public int ModuleId { get; set; }
public int? LectureId { get; set; }
public string ModuleName { get; set; }
public string ModuleCode { get; set; }
public string Description { get; set; }
public string ModulePath { get; set; }
public virtual Lecture Lecture { get; set; }
public virtual ICollection<Order> Order { get; set; }
}
You only need to pass the created destination to the second map call:
Just try the following code when mapping:
var studMap = Mapper.Map<Student,StudentDetails>(student);
Mapper.Map<Module,StudentDetails>(module,studMap);
Then the studMap will receive all mapped fields value.
My class structure looks like this. What I'm trying to do is, create automap from source EmployeeInfo class to destination NewEmployeeInfo class and vise Versa.
public class EmployeeInfo ///// Old Employee class - Transform this into New
{
public int EmployeeID { get; set; }
public string EmployeeName { get; set; }
public int DepartmentID { get; set; }
public string DepartmentName { get; set; }
}
public class NewEmployeeInfo //// New Employee -- Transform in to this
{
public Employee Employee { get; set; }
public Department Department { get; set; }
}
public class Employee
{
public int EmployeeID { get; set; }
public string EmployeeName { get; set; }
}
public class Department
{
public int DepartmentID { get; set; }
public string DepartmentName { get; set; }
}
when i use AutoMapper for mapping my ViewModels and get All News, thrown error for me.
Errors...
The following property on Mosque.Core.ViewModels.CategoryViewModel cannot be mapped:
Categories
Add a custom mapping expression, ignore, add a custom resolver, or modify the destination type Mosque.Core.ViewModels.CategoryViewModel.
please help me, thank you
//Models
public class News
{
public int Id { get; set; }
public string Title { get; set; }
public virtual ICollection<Category> Categories { get; set; }
public virtual User User { get; set; }
}
public class Category

public int Id { get; set; }
public string Title { get; set; }
public virtual ICollection<News> News { get; set; }
}
public class User
{
public int Id { get; set; }
public string Name { get; set; }
public virtual ICollection<News> News { get; set; }
}
//ViewModels
public class NewsViewModel
{
public int Id { get; set; }
public string Title { get; set; }

}
public class CategoryViewModel

}
public class UserViewModel
{
public int Id { get; set; }
public string Name { get; set; }
public virtual ICollection<NewsViewModel> News { get; set; }
}
how do i use for select All News?
--Update1--
I used onion architecture in the project and i installed AutoMapper in the Service layer and i want get all news from repository and fill into ViewModels and pass to the UI.
my code in service layer is...
public List<NewsViewModel> GetAll()
{
Mapper.CreateMap<News, NewsViewModel>()
.ForMember(dest => dest.Categories, src => src.MapFrom(p => p.Categories))
.ForMember(dest => dest.User, src => src.MapFrom(p => p.User));
Mapper.AssertConfigurationIsValid();
var viewModels = new List<NewsViewModel>();
foreach (var item in _newsRepository.GetAll())
{
var viewModel = Mapper.Map<News, NewsViewModel>(item);
viewModels.Add(viewModel);
}
return viewModels;
}
You don't seem to have created maps for Catagory and User.
Add the following maps:
Mapper.CreateMap<User, UserViewModel>();
Mapper.CreateMap<Category, CategoryViewModel>();
By the way, why are you creating the maps inside the GetAll method? You can create the maps once, usually at application startup.
I have a problem with devising a many to many relationship in code first. EF is creating the Junction table and associating the Fk's as I would expect, however when i try to access the User's MailingList collection, there are no entries.
I've implemented test data on Initialise via Seeding, the data is al present in the database.
I think the problem lies with the constructors for Users and MailingLists, but I'm uncertain. I want to be able to navigate the navigational property of User.MailingLists.
var user = db.Users.Find(1);
Console.WriteLine("{0}", user.EmailAddress); //This is Fine
Console.WriteLine("{0}", user.Address.PostCode); /This is Fine
foreach (MailingList ml in user.MailingLists) // this is 0
{
Console.WriteLine("{0}", ml.Name);
}
My model is below:-
public class User : IEntityBase
{
public User()
{
MailingLists = new List<MailingList>();
}
public int Id { get; set; }
public string Forename { get; set; }
public string Surname { get; set; }
public string EmailAddress { get; set; }
public DateTime? DateLastUpdated { get; set; }
public DateTime DateCreated { get; set; }
public bool IsDeleted { get; set; }
public virtual Address Address { get; set; }
public ICollection<MailingList> MailingLists { get; set; }
}
public class MailingList : IEntityBase
{
public MailingList()
{
Users = new List<User>();
}
public int Id { get; set; }
public string Name { get; set; }
public DateTime? DateLastUpdated { get; set; }
public DateTime DateCreated { get; set; }
public bool IsDeleted { get; set; }
public ICollection<User> Users { get; set; }
}
public class Address : IEntityBase
{
public int Id { get; set; }
public string AddressLine1 { get; set; }
public string AddressLine2 { get; set; }
public string AddressLine3 { get; set; }
public string City { get; set; }
public string County { get; set; }
public string PostCode { get; set; }
public DateTime? DateLastUpdated { get; set; }
public DateTime DateCreated { get; set; }
public bool IsDeleted { get; set; }
}
Any suggestions welcome.
You are neither eager loading the MailingList entries with the query, nor fulfulling the requirements for a lazy loading proxy so there is no way EF can populate the collection.
To allow lazy loading, change the MailingList property to be virtual to allow the EF proxy to override it.
To use eager loading, use Include() (an extension method in System.Data.Entity) in the query to specify that the MailingList should be loaded.
I'm new with AutoMapper and have a problem I'm trying to solve.
If I have a source class like this:
public class Membership
{
public int MembershipId { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string OrganizationName { get; set; }
public List<Address> Addresses { get; set; }
}
And the Address class looks like this:
public class Address
{
public int AddressId{ get; set; }
public int RefAddressTypeId { get; set; }
public string AddressLine1 { get; set; }
public string AddressLine2 { get; set; }
public string City { get; set; }
public string State { get; set; }
public string Zip { get; set; }
public bool IsPreferredAddress { get; set; }
}
My destination class is:
public class UserInformationModel
{
public string UserName { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string Organization { get; set; }
public string EmailAddress { get; set; }
public PhysicalAddress BillingAddress { get; set; }
public PhysicalAddress ShippingAddress { get; set; }
}
And the destination address class is:
public class PhysicalAddress
{
public AddressType AddressType{get; set;}
public string AddressLine1 { get; set; }
public string AddressLine2 { get; set; }
public string City { get; set; }
public string State { get; set; }
public string PostalCode { get; set; }
}
I have set up a mapping like this:
Mapper.CreateMap<MinistryMattersIntegration.BusinessObjects.Entities.Cokesbury.Membership, UserInformationModel>()
.ForMember(dest => dest.Organization, opt => opt.MapFrom(src=>src.OrganizationName));
This is working for Membership to UserInformationModel, but now I need to get addresses working. One important thing to note, though, is that the destination is a single billing address and a single shipping address while in the original model, all the address are stored as a list. The way you find the shipping and billing addresses out of the list is by looking at the RefAddressTypdId and the IsPreferredAddress. Only one preferred address may exist with a particular RefAddressTypeId.
So, my question is, how do you get AutoMapper to do this kind of mapping? Is it possible, or am I better off just going with regular mapping code?
You'll want to use the Custom Value Resolvers feature of AutoMapper. So you'd setup a Custom Resolver to map from your list to your single entity using the IsPreferredAddress flag to find it.
The documentation is pretty good for the Custom Resolvers so you should be fine figuring it out from there.
