Automapper fails to translate generic lists - c#

I have two collections of the following classes that I want to map:
public class Client_Crime_ViewModel
{
public Client_Crime_ViewModel() { }
public Client_Crime_ViewModel(CrimeIncident ci)
{
Id = ci.Id;
CaseNumber = ci.CaseNumber;
DateOfIncident = ci.DateOfIncident;
Description = ci.Description;
}
public Int64 Id
{
get;
set;
}
[Required]
[DisplayName("Case Number")]
public string CaseNumber { get; set; }
[DataType(DataType.Date)]
[Required]
[DisplayName("Date of Incident")]
public string DateOfIncident { get; set; }
[DataType(DataType.MultilineText)]
[Required]
public string Description { get; set; }
}
public class CrimeIncident
{
public Int64 Id { get; set; }
[Required]
public string CaseNumber { get; set; }
[Required]
public string Description { get; set; }
[DataType(DataType.Date)]
public string DateOfIncident { get; set; }
public CrimeIncident() { }
public CrimeIncident(string caseNumber, string dateOfIncident, string description)
{
CaseNumber = caseNumber;
Description = description;
DateOfIncident = dateOfIncident;
}
}
I have tried mapping in both of the following ways:
Method 1:
Mapper.CreateMap<List<Client_Crime_ViewModel>, List<CrimeIncident>>();
List<Client_Crime_ViewModel> cvmList = System.Web.Helpers.Json.Decode<System.Collections.Generic.List<Client_Crime_ViewModel>>(rb.Form["CrimeCollection"]);
List<CrimeIncident> ciList = Mapper.Map<List<Client_Crime_ViewModel>, List<CrimeIncident>>(cvmList);
Method 2:
Mapper.CreateMap<List<Client_Crime_ViewModel>, List<CrimeIncident>>();
List<Client_Crime_ViewModel> cvmList = System.Web.Helpers.Json.Decode<System.Collections.Generic.List<Client_Crime_ViewModel>>(rb.Form["CrimeCollection"]);
List<CrimeIncident> ciList = Mapper.Map<List<CrimeIncident>>(cvmList);
Both methods fail. Debugging reveals that although the element count for cvmList is > 0, the element count for ciList remains at 0.
Any idea what I am doing wrong?
Thanks in advance.

You don't need to create a map for a list, just map the entities.

Elastic search Nest (.Net) Total and Documents don't match

I'm having the following situation: the Total from the Valid Nest Response is equals 2 and the Documents count equal 0. I'm not sure how that is possible.
Found the solution. The problem was in my model. You see, my model was something like that:
public class Customer
{
public string Id { get; set; }
public string Name { get; set; }
public string Nickname { get; set; }
public string PersonType { get; set; }
public string Gender { get; set; }
public string MaritalStatus { get; set; }
[DataType(DataType.Date)]
[DisplayFormat(DataFormatString = "{dd/MM/yyyy HH:mm:ss}")]
public DateTime? BirthDate { get; set; }
}
And this Index had Documents missing some fields, like:
public class Customer
{
public string Id { get; set; }
public string Name { get; set; }
public string PersonType { get; set; }
public string Gender { get; set; }
}
The solution was adding the decorator PropertyName from Nest, to Map my model, like this:
public class Customer
{
[PropertyName("id")]
public string Id { get; set; }
[PropertyName("name")]
public string Name { get; set; }
[PropertyName("nickname")]
public string Nickname { get; set; }
[PropertyName("personType")]
public string PersonType { get; set; }
[PropertyName("gender")]
public string Gender { get; set; }
[PropertyName("maritalStatus")]
public string MaritalStatus { get; set; }
[PropertyName("birthDate")]
[DataType(DataType.Date)]
[DisplayFormat(DataFormatString = "{dd/MM/yyyy HH:mm:ss}")]
public DateTime? BirthDate { get; set; }
}
Now it works!

How to to make properties visible when the Foreign Key comes up as ICollection<T> type in Entity Framework's .edmx's .tt classes [.NET]

I have 2 Tables in the SQL Server SUST_HC_DTLS [Primary Key Column Name = SUST_ID] and the second table is SUST_INC_TRCKR_DTLS [Foreign Key = SUST_HANDLER (it references SUST_ID column of first table. This Table also has a Primary Key column = INC_NBR)].Now when i create the Entity Data Model. It create 2 partial classes for both the Table. As show Below --
For Table = SUST_HC_DTLS (Primary Key Table)
public partial class SUST_HC_DTLS
{
[System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2214:DoNotCallOverridableMethodsInConstructors")]
public SUST_HC_DTLS()
{
this.SUST_INC_TRCKR_DTLS = new HashSet<SUST_INC_TRCKR_DTLS>();
}
public int SUST_ID { get; set; }
public string HC_NAME { get; set; }
public string HC_EMAIL { get; set; }
public Nullable<System.TimeSpan> SHIFT_START { get; set; }
public Nullable<System.TimeSpan> SHIFT_END { get; set; }
public Nullable<System.DateTime> JOINED_ON { get; set; }
public Nullable<System.DateTime> UPDTD_AT { get; set; }
public string UPDTD_BY { get; set; }
[System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2227:CollectionPropertiesShouldBeReadOnly")]
public virtual ICollection<SUST_INC_TRCKR_DTLS> SUST_INC_TRCKR_DTLS { get; set; }
}
For Secondary Table = SUST_INC_TRCKR_DTLS (Foreign Key Table)
public partial class SUST_INC_TRCKR_DTLS
{
public string INC_NBR { get; set; }
public string REASON_4_INC { get; set; }
public string RAISED_BY { get; set; }
public int SUST_HANDLER { get; set; }
public string COMMENTS { get; set; }
public string CURRENT_STTS { get; set; }
public Nullable<System.DateTime> CREATED_ON { get; set; }
public string DTLS_ENTRD_BY { get; set; }
public Nullable<System.DateTime> UPDTD_ON { get; set; }
public string DTLS_UPDTD_BY { get; set; }
public virtual SUST_HC_DTLS SUST_HC_DTLS { get; set; }
}
Now, I have separate Class Library for My Models for these respective Table and Below are the Classes in the Class Library --
For Primary Table --
public class HC_TBL
{
[Required]
public int SUST_ID { get; set; }
[Required]
public string HC_NAME { get; set; }
[EmailAddress]
public string HC_EMAIL { get; set; }
[Required]
[DataType(DataType.Time)]
public TimeSpan? SHIFT_START { get; set; }
[Required]
[DataType(DataType.Time)]
public TimeSpan? SHIFT_END { get; set; }
[Required]
[DataType(DataType.Date)]
[DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = true)]
public DateTime? JOINED_ON { get; set; }
public DateTime? UPDTD_AT { get; set; }
public string UPDTD_BY { get; set; }
public INC_Trckr_TBL Trckr_TBL { get; set; }
}
For Foreign Key Table
public class INC_Trckr_TBL
{
public string INC_NBR { get; set; }
//[Required]
public string REASON_4_INC { get; set; }
//[Required]
public string RAISED_BY { get; set; }
public int SUST_HANDLER { get; set; }
public string COMMENTS { get; set; }
//[Required]
public string CURRENT_STTS { get; set; }
public DateTime? CREATED_ON { get; set; }
public string DTLS_ENTRD_BY { get; set; }
public DateTime? UPDTD_ON { get; set; }
public string DTLS_UPDTD_BY { get; set; }
}
Now when i do the Database Operations to get all records from the Database. Its not letting me call Foreign key properties /fields. It doesn't even provide them in the list.
However, when i do the LINQ Select from the options i get, i do get the property but then it gives me the error -- Cannot implicitly convert type System.Collections.Generic.IEnumerable to GDE.Model.INC_Trckr_TBL. An explicit conversion exists (Are you missing one?).
Now when i do the explicit conversion it says --
System.NotSupportedException
HResult=0x80131515
Message=Values of type 'collection[Edm.String(Nullable=True,DefaultValue=,MaxLength=20,Unicode=False,FixedLength=False)]' can not be converted to string.
I Honestly don't know what to do anymore. Below is my DBOperations Repository Code --
public List<SustHCModel> GetAllDetails()
{
using (var context = new GDE_SUSTEntities())
{
var result= context.SUST_HC_DTLS.Select(x => new SustHCModel()
{
SUST_ID = x.SUST_ID,
HC_NAME = x.HC_NAME,
HC_EMAIL = x.HC_EMAIL,
SHIFT_START = x.SHIFT_START,
SHIFT_END = x.SHIFT_END,
JOINED_ON = x.JOINED_ON,
IncTrckrModel = new INCTrckrModel()
{
INC_NBR = x.SUST_INC_TRCKR_DTLS.Select(y => y.INC_NBR).ToString(),
REASON_4_INC = x.SUST_INC_TRCKR_DTLS.Select(y => y.REASON_4_INC).ToString(),
RAISED_BY = x.SUST_INC_TRCKR_DTLS.Select(y => y.RAISED_BY).ToString(),
COMMENTS = x.SUST_INC_TRCKR_DTLS.Select(y => y.COMMENTS).ToString(),
CURRENT_STTS = x.SUST_INC_TRCKR_DTLS.Select(y => y.CURRENT_STTS).ToString()
}
}).ToList();
return result;
}
}
I am new to this. So, i am pretty sure that i have made some mistake somewhere. So, please guide me and my apologies in advance for whatever silly mistake i have made.

Sort Main-List by property of Sublist in LINQ

Currently i have the following structure of my classes:
public class StoreElement
{
[Display(Name="ID")]
public int StoreElementId { get; set; }
[Display(Name = "RegalID")]
public string StoreElementCode { get; set; }
[Display(Name = "Regal")]
public string Storage { get; set; }
[Display(Name="Ebene")]
public string Level { get; set; }
[Display(Name = "Fach")]
public string Shelf { get; set; }
[Display(Name = "ESL Tag")]
public string ESLTagId { get; set; }
[Display(Name ="ESL Layout Template")]
public string ESLLayoutValue { get; set; }
[Display(Name = "Eingelagertes Material")]
public List<Material> Materials { get; set; }
}
And this class:
public class Material
{
[Display(Name = "ID")]
public int MaterialId { get; set; }
[Display(Name = "Materialnummer")]
public int? MaterialNumber { get; set; }
[Display(Name = "Auftragsnummer")]
public int? OrderNumber { get; set; }
[Display(Name = "Eingelagert")]
public bool? IsStored { get; set; }
[Display(Name = "Einlagerdatum")]
public DateTime StoredAt { get; set; }
[Display(Name = "Auslagerdatum")]
public DateTime OutsourcedAt { get; set; }
[Display(Name = "Liefertermin")]
public DateTime DeliveryDate { get; set; }
[Display(Name = "Priorisiertes Material")]
public bool PriorityMaterial { get; set; }
public int? StoreElementId { get; set; }
public StoreElement StoreElement { get; set; }
}
A StoreElement can hold a List of Materials. The class Materials contains a property which is a date. Now i would like to order the Storage-Location List by the subproperty date of a list of materials.
I tried something in linq like that:
var myOrderdStorageLocationsByDeliveryDateOfMaterialsSublist = this.MyDatabaseContext.StorageLocations.Include(x=>x.Materials).OrderBy(x=>x.Materials.OrderBy(y=>y.DeliveryDate)).ToList();
But this throws an exception that says "Failed to compare two elements in the array"
Obviously, you need some value from Materials. And OrderBy won't return it.
I would recommend you to get a particular value for sorting StoreElements based on what logic you need: Min, Max or Average for example.
var myOrderdStorageLocationsByDeliveryDateOfMaterialsSublist = this.MyDatabaseContext.StorageLocations
.Include(x=>x.Materials)
.OrderBy(x=>x.Materials.Min(y=>y.DeliveryDate))
.ToList();

Entity Framework - Update action and Automapper

For example, I have the following infrastructure class:
[Table("GeoHistory")]
public partial class GeoHistory
{
public int Id { get; set; }
public int CompanyId { get; set; }
public int DriverId { get; set; }
[StringLength(50)]
public string Name { get; set; }
public string Description { get; set; }
[StringLength(100)]
public string GeofenceLocation { get; set; }
[StringLength(100)]
public string GeofencePrevious { get; set; }
[StringLength(20)]
public string StateLocation { get; set; }
[StringLength(20)]
public string StatePrevious { get; set; }
public DateTime? DateTime { get; set; }
[StringLength(5)]
public string Heading { get; set; }
public decimal? Speed { get; set; }
[StringLength(50)]
public string Status { get; set; }
}
and the following View class (let's forget about domain layer):
public class GeoHistoryViewModel
{
public int Id { get; set; }
public int? CompanyId { get; set; }
public int? DriverId { get; set; }
[StringLength(50)]
public string Name { get; set; }
public string Description { get; set; }
}
as we can see, we edit only part of field list.
Now, we want to update data in DB. Of course, we can write like:
Infrastructure.Main.GeoHistory geoHistory = db.GeoHistories.Find(id);
geoHistory.CompanyId = model.CompanyId;
geoHistory.DriverId = model.DriverId;
geoHistory.Name = model.Name;
........
db.SaveChanges();
It works. But I want to use Automapper. And if I try to do the following:
Infrastructure.Main.GeoHistory geoHistory = mapper.Map<Infrastructure.Main.GeoHistory>(model);
db.GeoHistories.Attach(geoHistory);
db.Entry(geoHistory).State = EntityState.Modified;
db.SaveChanges();
It works, but of course remove values of fields, which are not exist in View Model, but exist in infrastructure class. How to use automapper, but don't lost these fields?

cannot do asqueryable on mongodb collection

I got two models, a User and a Team as below:
[BsonRepresentation(BsonType.ObjectId)]
public ObjectId _id { get; set; }
[Display(Name = "Password:")]
public string Password { get; set; }
[Display(Name = "Confirm:")]
public string ConfirmPassword { get; set; }
[Display(Name = "Email:")]
public string Email { get; set; }
[Display(Name = "Username:")]
public string UserName { get; set; }
[Display(Name = "Firtname:")]
public string Firstname { get; set; }
[Display(Name = "Lastname:")]
public string Lastname { get; set; }
[Display(Name = "Country:")]
public string Country { get; set; }
[Display(Name = "City:")]
public string City { get; set; }
[Display(Name = "Birthdate:")]
public int Birthdate { get; set; }
public List<Team> Teams { get; set; }
[BsonRepresentation(BsonType.ObjectId)]
public ObjectId TeamID { get; set; }
public string TeamName { get; set; }
public string UserName { get; set; }
public int LeagueID { get; set; }
public List<Player> Player { get; set; }
So I've created a user but now I want to add teams to my user.
This is the code I'm using:
var databaseClient = new MongoClient(Settings.Default.FantasySportsConnectionString);
var server = databaseClient.GetServer();
var database = server.GetDatabase("Users");
var collection = database.GetCollection<User>("users");
var user = collection.AsQueryable().First(o => o._id == Session["ID"]);
user.Teams.Add(new Team { TeamID = new ObjectId(), TeamName = "Some Team" });
But when I do this I get these errors:
1: Instance argument: cannot convert from 'MongoDB.Driver.MongoCollection<SportsFantasy_2._0.Models.User>' to 'System.Collections.IEnumerable'
2: 'MongoDB.Driver.MongoCollection<SportsFantasy_2._0.Models.User>' does not contain a definition for 'AsQueryable' and the best extension method overload 'System.Linq.Queryable.AsQueryable(System.Collections.IEnumerable)' has some invalid arguments
You are missing a namespace, MongoDB.Driver.Linq, simply add that at the top:
using MongoDB.Driver.Linq;
That specific method is:
LinqExtensionMethods
{
public static IQueryable<T> AsQueryable<T>(this MongoCollection<T> collection);
//...
}
I was getting the same error with with the .NET driver v2.3.0. I removed it and installed v2.2.4 using NuGet and it worked. The error I kept getting:
Method not found: 'MongoDB.Driver.Linq.IMongoQueryable1<!!0> MongoDB.Driver.IMongoCollectionExtensions.AsQueryable(MongoDB.Driver.IMongoCollection1)'.
