The problem I'm encountering is when I try to insert a new record in a ASPxGridView which is a master of detail in an asp.net page.
This only occurs when adding a new record is required when there is no record.
EnderecoEscola entity:
namespace DAL
{
[Table("CAD_ENDERECO_ESCOLA")]
public class EnderecoEscola
{
[Key]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int ENDESC_ID { get; set; }
[Required]
public int ESCOLA_ID { get; set; }
[Association("Escolas", "ESCOLA_ID", "ESCOLA_ID")]
[ForeignKey("ESCOLA_ID")]
public virtual Escola Escola { get; set; }
[Required]
public int TPOEND_ID { get; set; }
[ForeignKey("TPOEND_ID")]
public virtual TipoEndereco TipoEndereco { get; set; }
[Required]
public int ENDESC_UF_ID { get; set; }
[ForeignKey("ENDESC_UF_ID")]
public virtual UnidadeFederativa UnidadeFederativa { get; set; }
[Required]
public int ENDESC_MUN_iD { get; set; }
[ForeignKey("ENDESC_MUN_iD")]
public virtual Municipio Municipio { get; set; }
[StringLength(10), Required]
[MinLength(8)]
public string ENDESC_CEP { get; set; }
[StringLength(100), Required]
[MinLength(10)]
public string ENDESC_ENDERECO { get; set; }
[StringLength(15)]
public string ENDESC_NRO { get; set; }
[StringLength(25)]
public string ENDESC_COMPL { get; set; }
[StringLength(70)]
public string ENDESC_BAIRRO { get; set; }
[NotMapped]
public String TPEND_DESCRICAO { get; set; }
[NotMapped]
public String UF_SIGLA { get; set; }
[NotMapped]
public String MUN_DESCRICAO { get; set; }
}
}
DAL :
namespace DAL.utilities
{
public class OperationCadEnderecoEscola
{
public IQueryable<EnderecoEscola> GetId(int idEsc)
{
using (SecurityCtx ctx = new SecurityCtx())
{
ctx.Configuration.LazyLoadingEnabled = false;
var query = ctx.EnderecoEscola.Include("TipoEndereco").Include("UnidadeFederativa").Include("Municipio").Where(w => w.ESCOLA_ID == idEsc).OrderBy(p => p.ENDESC_ENDERECO).ToList().
Select(w => new EnderecoEscola
{
ENDESC_ID = w.ENDESC_ID,
ESCOLA_ID = w.ESCOLA_ID,
TPOEND_ID = w.TPOEND_ID,
ENDESC_UF_ID = w.ENDESC_UF_ID,
ENDESC_MUN_iD = w.ENDESC_MUN_iD,
ENDESC_CEP = w.ENDESC_CEP,
ENDESC_ENDERECO = w.ENDESC_ENDERECO,
ENDESC_NRO = w.ENDESC_NRO,
ENDESC_COMPL = w.ENDESC_COMPL,
ENDESC_BAIRRO = w.ENDESC_BAIRRO,
TPEND_DESCRICAO = w.TipoEndereco.TPEND_DESCRICAO != null ? w.TipoEndereco.TPEND_DESCRICAO : w.TPEND_DESCRICAO,
UF_SIGLA = w.UnidadeFederativa.UF_SIGLA != null ? w.UnidadeFederativa.UF_SIGLA : w.UF_SIGLA,
MUN_DESCRICAO = w.Municipio.MUN_DESCRICAO != null ? w.Municipio.MUN_DESCRICAO : w.MUN_DESCRICAO
}).Distinct().AsQueryable();
return query;
}
}
}
}
When applying for inclusion in ASPxGridView a new record and the method in DAL public IQueryable <EnderecoEscola> getId (int idEsc) is invoked to retrieve the data and they do not exists it is adding a new record on the master and detail occurs error
A field or property with name 'TPEND_DESCRICAO' was not found in the
selected data source.
Someone could guide me on how to solve the problem.
Tks.

I have entity
public class ImageTeam
{
public int Id { get; set; }

}
config data context
modelBuilder.Entity<Team>(entity =>
{
entity.HasMany(x => x.ListAvatar)
.WithOne(t => t.Team)
.HasForeignKey(pv => pv.TeamID);
});
when I post the data insert a new record entity ImageTeam then it show exception
I need to do...Help me
In the Team class you add another relation ListBanner to ImageTeam class ,you have not set an foreign key for it, so EF automatically creates a TeamID and because TeamId already in the class, it's throw exception . You also need to set an foreign key for second relation.
public class ImageTeam
{
public int Id { get; set; }
public int TeamID { get; set; }
public Team Team { get; set; }
public int BannerTeamId { get; set; }
public Team BannerTeam { get; set; }
public int PostTeamID { get; set; }
public string Image { get; set; }
public int ImageType { get; set; }
public int StatusPublic { get; set; }
public int StatusActive { get; set; }
public DateTime CreatedAt { get; set; }
}
entity.HasMany(x => x.ListAvatar)
.WithOne(t => t.Team)
.HasForeignKey(pv => pv.TeamID).OnDelete(DeleteBehavior.Restrict);
entity.HasMany(x => x.ListBanner)
.WithOne(t => t.BannerTeam)
.HasForeignKey(pv => pv.BannerTeamId).OnDelete(DeleteBehavior.Restrict);
I have found a solution:
edit Team entity:
public class Team
{
public int Id { get; set; }
public string Name { get; set; }
public int NoMember { get; set; }
public float Score { get; set; }
public int StatusActive { get; set; }
public int TeamType { get; set; }
public virtual List<TeamGroup> ListMember { get; set; }
public virtual List<ImageTeam> ListImage { get; set; }
public DateTime CreatedAt { get; set; }
}
*no config data context
create new model: TeamViewModel
public class TeamViewModel
{
public int Id { get; set; }
public string Name { get; set; }
public int NoMember { get; set; }
public float Score { get; set; }
public int StatusActive { get; set; }
public int TeamType { get; set; }
public virtual List<TeamGroupViewModel> ListMember { get; set; }
public virtual List<ImageTeam> ListImage { get; set; }

public virtual List<ImageTeam> ListBanner { get; set; }
public virtual List<ImageTeam> ListPost { get; set; }
}
in controller :

I don't know if I am doing this right. I have 2 tables Property and PropertyTypes. Each Property has 1 PropertyType. I am using a foreign key constraint. But on the creation of the controller, I get this error already:
"Could not find an implementation of the query pattern for source type 'DbSet'.'Join not found'
Please see my code below:

Can you please show me the right way to do this? Thank you.
I have this as my entity object:
public partial class RFID_Zones
{
public RFID_Zones()
{
this.RFID_ZonePoints = new HashSet<RFID_ZonePoints>();
}
public int PK_ZoneId { get; set; }
public int PK_FK_ShipId { get; set; }
public string ZoneName { get; set; }
public string Color { get; set; }
public virtual Ship Ship { get; set; }
public virtual ICollection<RFID_ZonePoints> RFID_ZonePoints { get; set;}
}
I am trying to pull all these with this code:
result = _db.RFID_Zones.Where(x => x.PK_FK_ShipId == shipId).Include(x => x.RFID_ZonePoints).ToList();
This works, but I cannot serialize it without getting a circular reference error. Upon Googling I find I should use a Data Transfer Object so I have this:
public class ZoneDto
{
public ZoneDto()
{
this.Zones = new List<RFID_ZonePoints>();
}
public int PK_ZoneId { get; set; }
public int PK_FK_ShipId { get; set; }
public string ZoneName { get; set; }
public string Color { get; set; }
public List<RFID_ZonePoints> Zones { get; set; }
}
And:
var dto = zones.Select(x => new ZoneDto { PK_ZoneId = x.PK_ZoneId, PK_FK_ShipId = x.PK_FK_ShipId,
Color = x.Color, ZoneName = x.ZoneName, Zones = x.RFID_ZonePoints.ToList()});
I still have the issue of the RFID_ZonePoints list. It's a list of a different entity. How can I get those into a data transfer object as well?
When calling the method directly below I get a ObjectDisposedException when calling Mapper.Map with the retrieved list.
System.ObjectDisposedException: The ObjectContext instance has been disposed and can no longer be used for operations that require a connection.
public IEnumerable<Models.Provider> Get(string owner)
{
List<Data.Models.Provider> providers;
using (var db = new Data.ProviderDirectoryContext())
{
providers = db.Providers.Where(p => p.Owner.Name == owner).ToList();
}
var dtoProviders = Mapper.Map<List<Data.Models.Provider>, List<Models.Provider>>(providers);
return dtoProviders;
}
I previously had the code like this (below), I wasn't getting an error, but the database was getting pounded when doing the mapping, and it was taking too long. I don't want to hit the database, when doing the mapping.
public IEnumerable<Models.Provider> Get(string owner)
{
using (var db = new Data.ProviderDirectoryContext())
{
var providers = db.Providers.Where(p => p.Owner.Name == owner).ToList();
var dtoProviders = Mapper.Map<List<Data.Models.Provider>, List<Models.Provider>>(providers);
return dtoProviders;
}
}
How can I retrieve all the data before doing the mapping?
Here is the DbContext and the Data.Models.Provider for your reference.
public class ProviderDirectoryContext : DbContext
{
public DbSet<Owner> Owners { get; set; }
public DbSet<Location> Locations { get; set; }

public DbSet<ProviderType> ProviderTypes { get; set; }
public DbSet<ProviderSpecialty> ProviderSpecialties { get; set; }
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{

modelBuilder.Entity<Provider>().HasRequired(cn => cn.Owner).WithMany().WillCascadeOnDelete(false);
modelBuilder.Entity<Office>().HasRequired(cn => cn.Owner).WithMany().WillCascadeOnDelete(false);
}
}

}
Thanks for the help!
The problem is that the Models.Provider class contains other classes like Models.Office, and Models.PhoneNumbers that were not eagerly loaded by the query. In addition to that, the Models.Provider class needs to be flattened. The Mapper wants to recursively map everything, and it keeps going down to the next class. For example, Provider.Office.Location.Offices.
The solution is to flatten Models.Provider and add .Include() to the query so it eagerly loads the data required.
I'll clean this up a bit more, but this is currently working.
public IEnumerable<Models.Provider> Get(string owner)
{
List<Data.Models.Provider> providers;
using (var db = new Data.ProviderDirectoryContext())
{
providers = db.Providers
.Where(p => p.Owner.Name == owner)
.Include("ProviderType")
.Include("ProviderSpecialty")
.Include("Office")
.Include("PhoneNumbers")
.ToList();
}
var dtoProviders = Mapper.Map<List<Data.Models.Provider>, List<Models.Provider>>(providers);
return dtoProviders;
}
public class Provider
{
public int Id { get; set; }
public int OwnerId { get; set; }
public int OfficeId { get; set; }
public string OfficeName { get; set; }
public int? ProviderTypeId { get; set; }
public string ProviderTypeName { get; set; }
public int? ProviderSpecialtyId { get; set; }
public string ProviderSpecialtyName { get; set; }
public string FirstName { get; set; }
public string MiddleName { get; set; }
public string LastName { get; set; }
public string EmailAddress { get; set; }
public virtual ICollection<PhoneNumber> PhoneNumbers { get; set; }
public string Note { get; set; }
public DateTime? InactiveOn { get; set; }
public DateTime CreatedOn { get; set; }
public string CreatedBy { get; set; }
public DateTime ModifiedOn { get; set; }
public string ModifiedBy { get; set; }
}
I am not sure how much this will help with performance but declaring the variable you don't want to dispose outside the using statement should fix your dispose exception.
public IEnumerable<Models.Provider> Get(string owner)
{
IEnumerable<Models.Provider> dtoProviders;
using (var db = new Data.ProviderDirectoryContext())
{
List<Data.Models.Provider> providers = db.Providers.Where(p => p.Owner.Name == owner).ToList();
dtoProviders = Mapper.Map<List<Data.Models.Provider>, List<Models.Provider>>(providers);
}
return dtoProviders;
}
I'm new to automapper and I'm having a problem with it. In this case the automapper is used to map models(EntityFramework generated) to my own viewmodels. This is what happens, the sourcemodel with it's values is mapped to a destinationmodel but the dest values are always null. What's going on with the values?
Now what did I do:
I referenced the automapper to my project and bootstrapped the mappings.
public static void RegisterAutoMapperMappings()
{
Mapper.Initialize(x =>
{
// Add the mappingprofiles you configured below
x.AddProfile(new RegistrationViewModelProfile());
});
}
public static IMappingExpression<TSource, TDest> IgnoreAllUnmapped<TSource, TDest>(this IMappingExpression<TSource, TDest> expression)
{
expression.ForAllMembers(opt => opt.Ignore());
return expression;
}
public class RegistrationViewModelProfile : Profile
{
protected override void Configure()
{
CreateMap<RegistrationViewModel, contact>().IgnoreAllUnmapped();
CreateMap<contact, RegistrationViewModel>().IgnoreAllUnmapped();
CreateMap<RegistrationViewModel, emailaddress>().IgnoreAllUnmapped();
CreateMap<emailaddress, RegistrationViewModel>().IgnoreAllUnmapped();
CreateMap<RegistrationViewModel, password>().IgnoreAllUnmapped();
CreateMap<password, RegistrationViewModel>().IgnoreAllUnmapped();
//Always check if mapping is valid
Mapper.AssertConfigurationIsValid();
}
}
My viewmodel:
public class RegistrationViewModel
{
public HttpPostedFileBase file { get; set; }
public String EmailAddress { get; set; }
public String Password { get; set; }
public string contact_givenname { get; set; }
public string contact_surname_prefix { get; set; }
public string contact_surname { get; set; }
public string contact_gender { get; set; }
public string contact_country { get; set; }
public string contact_residence { get; set; }
public Nullable<DateTime> contact_birth_date{ get; set; }
public DateTime create_date { get; set; }
public ICollection<int> Contact_roles { get; set; }
public string Emailaddress_verificationkey { get; set; }
}
My model:
public partial class contact
{
public contact()
{
this.contact_connection_rel = new HashSet<contact_connection_rel>();
this.contact_emailaddress_password_rel = new HashSet<contact_emailaddress_password_rel>();
this.contact_emailaddress_rel = new HashSet<contact_emailaddress_rel>();
this.contact_service_role_rel = new HashSet<contact_service_role_rel>();
this.given_answer = new HashSet<given_answer>();
this.given_answer1 = new HashSet<given_answer>();
}
public int contact_id { get; set; }
public string contact_initials { get; set; }
public string contact_givenname { get; set; }
public string contact_surname_prefix { get; set; }
public string contact_surname { get; set; }
public string contact_nickname { get; set; }
public string contact_gender { get; set; }
public Nullable<System.DateTime> contact_birth_date { get; set; }
public string contact_country { get; set; }
public string contact_residence { get; set; }
public string contact_ssn { get; set; }
public Nullable<System.DateTime> create_date { get; set; }
public Nullable<System.DateTime> modify_date { get; set; }
public Nullable<System.DateTime> delete_date { get; set; }
public virtual ICollection<contact_connection_rel> contact_connection_rel { get; set; }
public virtual ICollection<contact_emailaddress_password_rel> contact_emailaddress_password_rel { get; set; }
public virtual ICollection<contact_emailaddress_rel> contact_emailaddress_rel { get; set; }
public virtual ICollection<contact_service_role_rel> contact_service_role_rel { get; set; }
public virtual ICollection<given_answer> given_answer { get; set; }
public virtual ICollection<given_answer> given_answer1 { get; set; }
}
And to test the configuration the following lines are used. The vars contain the destination objects but are always null:
contact c = new contact();
contact testC = unitOfWork.ContactRepository.Find(82);
var x = Mapper.Map<contact, RegistrationViewModel>(testC);
var y = Mapper.Map(regModel, c, typeof(RegistrationViewModel), typeof(contact));
var b = Mapper.DynamicMap<RegistrationViewModel, contact>(regModel);
var z = Mapper.Map<RegistrationViewModel, contact>(regModel, c);
var w = Mapper.Map<RegistrationViewModel, contact>(regModel);
expression.ForAllMembers(opt => opt.Ignore());
You're telling AutoMapper to ignore all properties, so nothing gets mapped.
If you just want to ignore non-matching properties, see this answer for one way, otherwise you're going to have to explicitly map each property between the objects.
