I'm trying to get a web app working based on the S#arp Architecture. At the moment I have a the below code for my entity.
[Serializable]
public abstract class EventBase : Entity
{
#region Properties
[DomainSignature]
public virtual string Name { get; set; }
public virtual string Description { get; set; }
public virtual AgeRange Ages { get; set; }
public virtual int Rating { get; set; }
public virtual decimal Price { get; set; }
public virtual string PhoneNumber { get; set; }
public virtual string EmailAddress { get; set; }
public virtual string Website { get; set; }
public virtual EventState State { get; set; }
#endregion
protected EventBase() {}
protected EventBase(string name, string description)
{
// ReSharper disable DoNotCallOverridableMethodsInConstructor
Name = name;
Description = description;
Price = 0;
State = EventState.New;
// ReSharper restore DoNotCallOverridableMethodsInConstructor
}
}
This is mapped using Fluent NHibernate as follows
public class EventBaseMap : AutoMap<EventBase>
{
public EventBaseMap()
{
Id(x => x.ID).WithUnsavedValue(-1).GeneratedBy.Identity();
Component<AgeRange>(x => x.Ages, m =>
{
m.Map(x => x.From).TheColumnNameIs("AgeFrom");
m.Map(x => x.To).TheColumnNameIs("AgeTo");
});
JoinedSubClass<Music>("EventId", sub =>
{
sub.Map(x => x.Headliner);
});
}
}
I created a very simple repository using the very useful S#arp base repository classes.
public interface IEventRepository : INHibernateRepositoryWithTypedId<EventBase, int>
{
List<EventBase> FindByName(string searchPhase);
}
public class EventRepository : NHibernateRepository<EventBase>, IEventRepository
{
public List<EventBase> FindByName(string searchPhase)
{
return Session.Linq<EventBase>().Where(x => x.Name == searchPhase).ToList();
}
}
I can create entities in the db and return all records. When I try to test the FindByName method I get the below error.
NHibernate.QueryException: could not
resolve property: Name of:
Model.Events.EventBase
Does anyone have any ideas? Is it a problem with my mapping?
Thanks,
This is using the Auto-mapping feature. I thought you only explicitly map properties that you want to override or that don't meet the conventions?
If I add an explicit mapping this solves the issue but I am still not sure why.

I am using aspnetboilerplate and added below configuration in preintiliaze in module. I have also added data annotation Audited to my entity but still it is not working. My entity is inheriting from AuditedEntity as don't need deleted feature. Please help
Configuration.EntityHistory.IsEnabled = true; Configuration.EntityHistory.Selectors.Add(new NamedTypeSelector("Abp.AuditedEntities", type => typeof(AuditedEntity).IsAssignableFrom(type)));
I have taken reference from here Can't enable Entity History in ASP.NET Zero
Below is entity definition
[Audited]
public partial class QuestionResponse : AuditedEntity<long>
{
public long ApplicationId { get; set; }
public long QuestionId { get; set; }
public string Response { get; set; }
public string Remark { get; set; }
public bool IsActive { get; set; }
public Application Application { get; set; }
public AbpUsers CreatorUser { get; set; }
public AbpUsers LastModifierUser { get; set; }
public Question Question { get; set; }
}
AuditedEntity<long> is not assignable to AuditedEntity.
Add a selector based on the interface IAuditedEntity instead.
Configuration.EntityHistory.Selectors.Add(
new NamedTypeSelector("Abp.AuditedEntities", type =>
// typeof(AuditedEntity).IsAssignableFrom(type)));
typeof(IAuditedEntity).IsAssignableFrom(type)));
Reference
From aspnetboilerplate/aspnetboilerplate's AuditedEntity.cs:
public abstract class AuditedEntity : AuditedEntity<int>, IEntity
{
}
public abstract class AuditedEntity<TPrimaryKey> : CreationAuditedEntity<TPrimaryKey>, IAudited
{
...
}
I have around 50 master tables that requires simple and straight forward CRUD operations, my tables are already available in the sql database.
My question is how to make it generic so that I dont need to create manually each individual page for master tables. I saw some ABP CRUDEntityAscyn classes in Boilerplate framework, but I am wondering how to bring it at Presentation layer (.cshtml).
If you need to create an application service that will have Create, Update, Delete, Get, GetAll methods for a specific entity, you can inherit from CrudAppService (or AsyncCrudAppService if you want to create async methods) class to create it easier. CrudAppService base class is generic which gets related Entity and DTO types as generic arguments and is extensible which allows you to override functionality when you need to customize it.
public class Task : Entity, IHasCreationTime
{
public string Title { get; set; }
public string Description { get; set; }
public DateTime CreationTime { get; set; }
public TaskState State { get; set; }
public Person AssignedPerson { get; set; }
public Guid? AssignedPersonId { get; set; }
public Task()
{
CreationTime = Clock.Now;
State = TaskState.Open;
}
}
[AutoMap(typeof(Task))]
public class TaskDto : EntityDto, IHasCreationTime
{
public string Title { get; set; }
public string Description { get; set; }
public DateTime CreationTime { get; set; }
public TaskState State { get; set; }
public Guid? AssignedPersonId { get; set; }
public string AssignedPersonName { get; set; }
}
public class TaskAppService : AsyncCrudAppService<Task, TaskDto>
{
public TaskAppService(IRepository<Task> repository)
: base(repository)
{
}
}
public interface ITaskAppService : IAsyncCrudAppService<TaskDto>
{
}
public class TaskAppService : AsyncCrudAppService<Task, TaskDto>, ITaskAppService
{
public TaskAppService(IRepository<Task> repository)
: base(repository)
{
}
}

I am creating POC using Asp.Net Web API. For mapping one object type to another i am using AutoMapper(v5.1.1). Here are the types which is being used for mapping:
//Entity
public class Goal : IVersionedEntity
{
public virtual int GoalId { get; set; }
public virtual string Title { get; set; }
public virtual string Description { get; set; }
public virtual DateTime StartDate { get; set; }
public virtual DateTime EndDate { get; set; }
public virtual string Reward { get; set; }
public virtual DateTime? DisabledDate { get; set; }
public virtual byte[] Version { get; set; }
public virtual User User { get; set; }
public virtual ICollection<Schedule> Schedules { get; set; }
}
//Model
public class Goal
{
private List<Link> _links;
public int GoalId { get; set; }
public string Title { get; set; }
public string Description { get; set; }
public DateTime? StartDate { get; set; }
public DateTime? EndDate { get; set; }
//public Status Status { get; set; }
public string Reward { get; set; }
public DateTime? DisabledDate { get; set; }
public User User { get; set; }
public ICollection<Schedule> Schedules { get; set; }
public List<Link> Links
{
get { return _links ?? (_links = new List<Link>()); }
set { _links = value; }
}
public void AddLink(Link link)
{
_links.Add(link);
}
}
I am mapping Goal Entity to Goal model type object as following:
public async System.Threading.Tasks.Task Configure()
{
Mapper.Initialize(cfg => cfg.CreateMap<Data.Entities.Goal, Models.Goal>()
.ForMember(m => m.Links, i => i.Ignore()));
}
and here is the 'AutoMapperConfigurator' class in 'App_Start':
public void Configure(IEnumerable<IAutoMapperTypeConfigurator> autoMapperTypeConfigurations)
{
autoMapperTypeConfigurations.ToList().ForEach(m => m.Configure());
Mapper.AssertConfigurationIsValid();
}
But it is throwing following exception:
The following property on TestApp.Web.Api.Models.Goal cannot be
mapped: Add a custom mapping expression, ignore, add a custom
resolver, or modify the destination type TestApp.Web.Api.Models.Goal.
Context: Mapping from type TestApp.Data.Entities.Goal to
TestApp.Web.Api.Models.Goal Exception of type
'AutoMapper.AutoMapperConfigurationException' was thrown.
See it's not showing which property is not getting mapped.
Any help for this isssue.
After spending hours on this, my final findings are follows:
You must have all your entity models and service models mapping correct to make it work. Even if one fails, the mentioned exception will be thrown. And if your complex type mappings are not correct you will get the above error.
In my case, I was missing how to configure the Complex Type with AutoMapper.
To configure Complex Type, either add .ForMember(m => m.Property, i => i.Ignore()) to ignore the complex type mapping if not needed or .ForMember(m => m.Property, i => i.MapFrom(j => Mapper.Map<Entity,ServiceModel>(j.Property))) for nested mapping (refer: http://www.softwarerockstar.com/2011/05/complex-object-mapping-using-automapper/) or use CustomMapping if there is come specific requirement during the mapping
I'm leveraging the Project functionality in Automapper and Entity Framework, but I'm running into an issue where Automapper doesn't seem to want to project one enum type to another.
I have the following entities:
public class UserProfile
{
public Guid Id { get; set; }
public string Name { get; set; }
private HashSet<UserProfilePhone> m_Phones;
public virtual HashSet<UserProfilePhone> Phones
{
get { return m_Phones ?? (m_Phones = new HashSet<UserProfilePhone>()); }
set { this.m_Phones = value; }
}
}
public class UserProfilePhone
{
public PhoneType Type { get; set; }
public virtual string Number { get; set; }
}
public enum PhoneType
{
Home = 1,
Work = 2,
Mobile = 3,
Other = 4
}
I then am projecting these types to the following models:
public class UserProfileModel
{
public Guid Id { get; set; }
public virtual string Name { get; set; }
public IEnumerable<UserProfilePhoneModel> Phones { get; set; }
}
public class UserProfilePhoneModel
{
public UserProfilePhoneTypeModel Type { get; set; }
public string Number { get; set; }
}
public enum UserProfilePhoneTypeModel
{
Home = 1,
Work = 2,
Mobile = 3,
Other = 4
}
I then setup my mappings like so:
Mapper.CreateMap<PhoneType, UserProfilePhoneTypeModel>();
Mapper.CreateMap<UserProfilePhone, UserProfilePhoneModel>();
Mapper.CreateMap<UserProfile, UserProfileModel>();
And finally I'm executing my projection:
var result = dbContext.UserProfiles.Project().To<UserProfileModel>();
When I do this, I get the following exception:
AutoMapper.AutoMapperMappingException: Unable to create a map expression from MyNamespace.PhoneType to
MyNamespace.Models.UserProfilePhoneTypeModel
Unable to create a map expression from MyNamespace.PhoneType to MyNamespace.Models.UserProfilePhoneTypeModel
Result StackTrace:
at System.Collections.Concurrent.ConcurrentDictionary2.GetOrAdd(TKey
key, Func2 valueFactory)
...
I've tried creating explicit mappings, but they appear to be ignored. What am I doing wrong here?
As usual, I figured out the answer almost as soon as I posted the question.
Modifying the create map line to provide an explicit cast did the trick:
Mapper.CreateMap<UserProfilePhone, UserProfilePhoneModel>()
.ForMember(m => m.Type, opt => opt.MapFrom(t => (UserProfilePhoneTypeModel)t.Type));
I am trying to figure out how to use Automapper when my entity has a field of type entity.
I've got 3 classes like these:
public abstract class Entity<IdK>
{
public virtual IdK Code { get; protected set; }
}
public class Contact : Entity
{
public virtual string Name { get; set; }
public virtual Company Company { get; set; }
}
public class Company : Entity
{
public virtual string Name { get; set; }
}
My class Contact contain an element of type Company.
I've also created a ViewModel to trasfer some infos to my view:
public ContactViewModel()
{
public Guid Code { get; set; }
public int Version { get; set; }
[DisplayName("Contact")]
public string Name { get; set; }
[DisplayName("Company")]
public string Company { get; set; }
}
In my viewmodel I've defined a field Company of type string. This is going to contain a value the user will chose from a dropdown (list of companies).
I've defined a bootstrapper when my App starts:
public class AutoMapperConfiguration
{
public static void Configure()
{
Mapper.Initialize(x => {
x.CreateMap<Domain.Contact, ViewModels.ContactViewModel>();
x.CreateMap<ViewModels.ContactViewModel, Domain.Contact>()
});
}
}
When I try to remap my ViewModel to my entity I get a conversion error (AutoMapper.AutoMapperMappingException).
Automapper can't figure out how to convert my Company (string) into an object of type Company, member of Contact.
Is it possible to define a rule so that Automapper know how to transform the string (company) into the code of my Company object, member of Contact?
You need to use a Resolver. Something like:
public class CompanyTypeResolver : ValueResolver<string, Company>
{
protected override Company ResolveCore(string name)
{
return new Company {Name = name};
}
}
Then in mapping code you call it like:
.ForMember(dto => dto.Company, opt => opt.ResolveUsing<CompanyTypeResolver>().FromMember(src => src.Name))
