Need to get all data from List without status and date
public class Locations
{
public string CompanyCode { get; set; }
public string SupplierId { get; set; }
public string LocationName { get; set; }
public int Status { get; set; }
public DteTime date{ get; set; }
public int ResultCode { get; set; }
public string ResultMessage { get; set; }
}
I getting all locations in below list, I want to avoid status and date from the results
List<Locations> results
You could make use Anonymous Types
results.Select(x=>new{x.CompanyCode,x.SupplierId,x.LocationName,x.ResultCode,x.ResultMessage})
Alternatively, you could create a Custom class with only the desired property and project it using Linq as shown in the example with Anonymous Types
or you can use deriving from class/interface and then cast to it ;)
you can do something like this:
public interface ILocationsPoorData
{
public string CompanyCode { get; set; }
public string SupplierId { get; set; }
public string LocationName { get; set; }
public int ResultCode { get; set; }
public string ResultMessage { get; set; }
}
class Locations:ILocationsPoorData
{
public string CompanyCode { get; set; }
public string SupplierId { get; set; }
public string LocationName { get; set; }
public int Status { get; set; }
public DteTime date{ get; set; }
public int ResultCode { get; set; }
public string ResultMessage { get; set; }
}
and in the end, when you'll have list of locations, you can do sth like this:
var newList = locationsList.select(x=> x as ILocationsPoorData)
or
var newList = locationsList.Cast<ILocationsPoorData>();
or you can create class instead of interface and do the same ;)
or you can use anonymous types like in previous answer
or you can create some value tuple instead of anonymous types ;)

Here is my Schema and with two Foreign Key in an intermediate table. I am beginner in Core dotnet so unable to crate API to show the department in the school.
public class DepartmentSchool
{
public int Id { get; set; }
public int DepartmentID { get; set; }
[ForeignKey("DepartmentID")]
public virtual Department Department{ get; set; }
public int SchoolsId { get; set; }
[ForeignKey("SchoolsId")]
public virtual Schools Schools { get; set; }
Here I want to get all department related to school id, how can i get all the department though the School id in dotnetcore API.
Here is the school class entity schema.
public partial class Schools
{
public int ID { get; set; }
public string UicCode { get; set; }
public int SchoolSystemsId { get; set; }
public string BannerUrl { get; set; }
public string Name { get; set; }
public string Description { get; set; }
public string ImageUrl { get; set; }
public int UserID { get; set; }
public int? Status { get; set; }
public DateTime? CreatedAt { get; set; }
public int? CreatedBy { get; set; }
public DateTime UpdatedAt { get; set; }
public int? ModifiedBy { get; set; }
[ForeignKey("SchoolSystemsId")]
public PrivateSchoolSystem PrivateSchoolSystems { get; set; }
And more here is the department schema.
public partial class Department
{
public int Id { get; set; }
public string Title { get; set; }
public DateTime CreatedAt { get; set; }
public DateTime UpdatedAt { get; set; }
public int CreatedBy { get; set; }
public int UpdatedBy { get; set; }
public int SchoolSystemsID { get; set; }
[ForeignKey("SchoolSystemsID")]
public virtual PrivateSchoolSystem PrivateSchoolSystems { get; set; }
And I am trying to get a department list in the query in the following controller.
[Route("api/[controller]")]
[ApiController]
public class DepartmentSchoolController : ControllerBase
{
private readonly learning_gpsContext _learning_GpsContext;
public DepartmentSchoolController(learning_gpsContext learning_GpsContext)
{
_learning_GpsContext = learning_GpsContext;
}
[HttpGet("school/{schoolId}/departments")]
public IActionResult GetDepartmentsFromSchool(int schoolId)
{
var school = _learning_GpsContext.Schools.Where(e=>e.Id == schoolId).FirstOrDefault();
if (school == null)
return NotFound();
var departments = _learning_GpsContext.DepartmentSchool
.Where(e=>e.SchoolsId == schoolId).Select(e=>e.Department);
return Ok(departments);
}
For further learning check this tutorial. You should also understand what REST is and for basic questions always take a look at the official documenation.
After reading the documentation, I am not sure but I have come to the conclusion that when creating QueryDb, you cannot choose the columns to join by? And I am under the impression, you must have DTO object to copy to? You cannot copy to a regular object or a dynamic object?
public class SampleAutoQueryDb : QueryDb<MailResponseDetailOrm, object>, ILeftJoin<MailResponseDetailOrm, MailResponseOrm> { }
Can anyone provide any insight on joining my MailResponseOrm to MailResponseDetailOrm. MailResponseDetailOrm has 5 fields namely the Email address. And I would like MailResponseOrm to be joined to it by Email as well. I also, for good measure do not want to alter either columnname. Would I have to create a custom implementation or a service to do this?
UPDATE
Here is my code as posted below:
[Alias("MailReportsDetail")]
public class MailResponseDetailOrm
{
public string Email { get; set; }
public int ID { get; set; }
[Alias("RespDate")]
public DateTime? AddedDateTime { get; set; }
[Alias("DLReport")]
public string Action { get; set; }
public string ActionDetail { get; set; }
public string IP { get; set; }
public string UserAgent { get; set; }
public string EmailReferrer { get; set; }
}
[Alias("MailReports")]
public class MailResponseOrm
{
public int ID { get; set; }
public string Email { get; set; }
public string Address1 { get; set; }
public string Address2 { get; set; }
public string City { get; set; }
public string Company { get; set; }
public string Contact { get; set; }
public string Country { get; set; }
[Alias("LastMail")]
public DateTime? ModifiedDateTime { get; set; }
[Alias("LastReport")]
public string Action { get; set; }
public DateTime? OptOut { get; set; }
public string Part { get; set; }
public string Phone { get; set; }
public string PostalCode { get; set; }
public string Source { get; set; }
public string State { get; set; }
public string Title { get; set; }
#region Obsolete
[Obsolete]
public string Class { get; set; }
[Obsolete]
public string IP { get; set; }
#endregion
}
public class SampleAutoQueryDb : QueryDb<MailResponseDetailOrm> { }
public class MyQueryServices : Service
{
public IAutoQueryDb AutoQuery { get; set; }
// Override with custom implementation
public object Any(SampleAutoQueryDb query)
{
var q = AutoQuery.CreateQuery(query, base.Request);
q.Join<MailResponseDetailOrm, MailResponseOrm>((x, y) => x.Email == y.Email)
// .Select<MailResponseDetailOrm, MailResponseOrm>((x, y) => new { x.ID, y.Email })
;
return AutoQuery.Execute(query, q);
}
}
Joins in AutoQuery needs to use OrmLite's Joins Reference conventions and all AutoQuery Services results are returned in a Typed DTO, which by default is the table being queried or you can use the QueryDb<From,Into> base class to return a custom result of columns from multiple joined tables.
You would need to use a Custom AutoQuery Implementation or your own Service implementation if you need customizations beyond this, e.g:
public class SampleAutoQueryDb : QueryDb<MailResponseDetailOrm> { }
public class MyQueryServices : Service
{
public IAutoQueryDb AutoQuery { get; set; }
// Override with custom implementation
public object Any(SampleAutoQueryDb query)
{
var q = AutoQuery.CreateQuery(query, base.Request);
q.Join<MailResponseDetailOrm,MailResponseOrm>((x, y) => x.Email == y.Email);
return AutoQuery.Execute(query, q);
}
}
// The query to join 2 objects on field names not specifically set in the class.
var q = Db.From<MailResponseDetailOrm>().Join<MailResponseDetailOrm>(x,y) => x.Email = y.Email);
// Run the query
var results = Db.Select(q);
So I am building an online shop using Code-First MVC
So I created this model classes for now (don't take the types of the attributes too serious for now):
Products (Produto):
public Produto()
{
ListaProdutoEncomenda = new HashSet<Produto_Encomenda>();
}
public int ProdutoID { get; set; }
[Required]
[StringLength(50)]
public string Nome { get; set; }
[Required]
public double Preco { get; set; }
[Required]
public double Peso { get; set; }
[Required]
[StringLength(255)]
public string Descricao { get; set; }
[Required]
public double IVA { get; set; }
public string Imagem { get; set; }
public DateTime UltimaAtualizacao { get; set; }
public int Stock { get; set; }
public int CategoriaID {get;set;}
public virtual ICollection<Produto_Encomenda> ListaProdutoEncomenda { get; set; }
}
Encomenda (Order):
public class Encomenda
{
public Encomenda()
{
ListaProdutoEncomenda = new HashSet<Produto_Encomenda>();
}
[Key]
public int IDEncomenda { get; set; }
[Required]
public DateTime DataSubmissao { get; set; }
[Required]
public DateTime DataEnvio { get; set; }
[Required]
public int EstadoEnvioID { get; set; }
[StringLength(50)]
public string NomeDestino { get; set; }
[Required]
public int TipoExpedicaoID { get; set; }
[Required]
public int RegiaoDestinoID { get; set; }
[StringLength(50)]
public string MoradaDestino { get; set; }
[StringLength(50)]
public string CodPostalDestino { get; set; }
[Required]
[StringLength(50)]
public string MoradaFaturacao { get; set; }
[Required]
[StringLength(50)]
public string CodPostalFaturacao { get; set; }
public virtual ICollection<Produto_Encomenda> ListaProdutoEncomenda { get; set; }
}
And the connection table between the produtos (Products) and Encomenda (Order)
public class Produto_Encomenda
{
[Key]
public int IDProduto_Encomenda { get; set; }
[Required]
public string NomeProduto { get; set; }
[Required]
public int Quantidade { get; set; }
[Required]
public float preco { get; set; }
[Required]
public float IVA { get; set; }
public virtual Encomenda Encomenda { get; set; }
public virtual Produto Produto { get; set; }
[ForeignKey("Encomenda")]
public int IDEncomendaFK { get; set; }
[ForeignKey("Produto")]
public int IDProdutoFK { get; set; }
}
So my question is..
Let's pretend that a costumer buys 2 or 3 products or more.
How can I store all this products in a single line of an order?
Cheers and thanks a lot in advance for the time spent reading.
I'm not sure what you mean by "a single line of an order". Each product is a separate line item, and your entities already model this through the many-to-many relationship.
However, in general this setup is a very bad idea. Your order should not be directly related to products. Instead, your order should simply have an order item, and you'll create those order items based on the products that were sold. The reason for this is that products are very likely to change. If a product is removed because it's no longer available, for example, that doesn't negate the fact that it was previously sold in an order. However, in order for referential integrity to be maintained, any orders sold with that product would have to also have their relationship with that product removed. By having an entirely separate entity, i.e. order item, products can come and go, while the already created orders remain unaffected.
I guess you are looking to make a viewmodel
Create a class that contains Products and Encomenda class as property -
Model -
public class MyViewModel
{
public Produto Pinst{get;set;}
public Encomenda Einst{get;set;}
}
Controller or method-
public void SomeMethod()
{
List<MyViewModel> lst = new List<MyViewModel>();
//Now suppose
foreach(var items in listThatGetCreatedWithBuyerproductInfo)
{
MyViewModel obj = new MyViewModel ();
obj.Pinst = new Produto();
obj.Einst = new Encomenda();
//Here goes your properties from item in respected class instances
obj.Pinst.Nome = items.Nome;
obj.Einst.DataSubmissao = items.DataSubmissao;
//when you are done loading add obj to list
lst.Add(obj);
}
}
Hope it Helps if it does not tell me !!
I've been reading through lots of articles trying to learn MVC4, but I'm stumped as to why my entity is not getting updated to database.
I've been trying to modify the MVC4 VS2012 Internet template.
So, here's the Controller action:
[HttpPost, ActionName("Approve")]
[Authorize]
public ActionResult ApproveConfirmed(long id)
{
using (StudentiContext context = new StudentiContext())
{
// context.Configuration.AutoDetectChangesEnabled = false;
var studente = (from d in context.STUDENTI_STRANIERI_MASTER_REG
where d.ID_PERSONA == id
select d).Single();
STUDENTI_STRANIERI_MASTER_REG st2 = studente;
st2.ESITO = 1;
//studente.ESITO = 1;
var statos = context.Entry(studente).State;
Console.WriteLine("Before DetectChanges: {0}",statos);
//context.ChangeTracker.DetectChanges();
context.Entry(studente).State = EntityState.Modified;
context.Entry(studente).CurrentValues.SetValues(st2);
// var tracked = context.ChangeTracker.Entries();
context.Entry(studente).Property( o => o.ESITO ).IsModified = true;
TryUpdateModel(studente);
context.SaveChanges();
Console.WriteLine("After DetectChanges: {0}",statos);
return RedirectToAction("PrivateIndex");
}
}
The aim is just to update one property, ESITO and set it to 1. Currently its value is 2.
This is the model:
namespace MvcStudenti2.Models
{
using System;
using System.Collections.Generic;
public partial class STUDENTI_STRANIERI_MASTER_REG
{
public long ID_PERSONA { get; set; }
public string COGNOME { get; set; }
public string NOME { get; set; }
public string SESSO { get; set; }

public string TITOLO_POSSEDUTO { get; set; }
public Nullable<short> DURATA_TITOLO { get; set; }
public string VOTAZIONE { get; set; }
public string UNI_PROVENIENZA { get; set; }
public long ID_STATO_UNI { get; set; }
public string CERT_LINGUISTICA { get; set; }
public string CERT_PUNTEGGIO { get; set; }
public string NOTE { get; set; }
public System.DateTime DATA_RICHIESTA { get; set; }
public short ESITO { get; set; }
public string CDS_COD { get; set; }
public string EMAIL { get; set; }
public string NUMERO_TELEFONO { get; set; }

public byte[] FILE_CARRIERA { get; set; }
public byte[] FILE_CERT_LINGUA { get; set; }
public byte[] FILE_DOC_IDENTITA { get; set; }
public string PWD { get; set; }
public string FILE_CV_NOME { get; set; }
public string FILE_CARRIERA_NOME { get; set; }
public string FILE_CERT_LINGUA_NOME { get; set; }
public string FILE_DOC_IDENTITA_NOME { get; set; }
public string FILE_CV_TIPO { get; set; }
public string FILE_CARRIERA_TIPO { get; set; }
public string FILE_CERT_LINGUA_TIPO { get; set; }
public string FILE_DOC_IDENTITA_TIPO { get; set; }
public Nullable<short> STATO { get; set; }
public Nullable<short> VALUTATO { get; set; }
public Nullable<short> ARCHIVIATO { get; set; }
public string CDS_COD_2 { get; set; }
public Nullable<short> MAIL_INVIATA { get; set; }
public string LINK_ULTIMO_CORSO { get; set; }
public Nullable<short> ATTIVO { get; set; }
public byte[] FILE_LETTERA_ACCETTAZIONE { get; set; }
public string FILE_LETTERA_ACCETTAZIONE_NOME { get; set; }
public string FILE_LETTERA_ACCETTAZIONE_TIPO { get; set; }
}
}
Everywhere I read I find that SaveChanges() should be enough, possibly after the EntityState.Modified.
I can correctly edit the entity, if I pass the whole entity to the Action, but in this case the Approve view is a built on a Detail template, so I don't have anything to POST from it (and I'd prefer not to: I could insert a hidden field and post just that, but I'm trying to update a single filed from code, and I'm not sure if the whole entity would get updated or overwritten ).
statos goes to "modified", if I understand correctly, because I have done a query on the entity.
Another thing I don't understand is why ESITO gets update -also- in studente, but then reverts to "2" after SaveChanges().
Are property changes being detected? I've wrapped every Action in a using block, as suggested elsewhere, so not to have multiple contextx/instances around.
Could anyone please point me to what I'm doing wrong? The code above is probably over-redundant, but I've been trying everything I have found on SO.
Thanks, everyone.
The following is all that is required to change the ESITO property.
[HttpPost, ActionName("Approve")]
[Authorize]
public ActionResult ApproveConfirmed(long id)
{
using (StudentiContext context = new StudentiContext())
{
// context.Configuration.AutoDetectChangesEnabled = false;
var studente = (from d in context.STUDENTI_STRANIERI_MASTER_REG
where d.ID_PERSONA == id
select d).Single();
studente.ESITO = 1;
context.SaveChanges();
return RedirectToAction("PrivateIndex");
}
}
I have an model like this:
public class EquipmentEmployee
{
public int EquipmentEmployeeID { get; set; }
public int EmployeeID { get; set; }
public Employee Employee { get; set; }
public int EquipmentID { get; set; }
public Equipment Equipment { get; set; }
public int RequisitionID { get; set; }
public Requisition Requisition { get; set; }
public DateTime From { get; set; }
public DateTime To { get; set; }
public string Comment { get; set; }
}
I use Mvc scaffolding for creating my controllers, repositories and views. Int the create View I'm not able to POST since I dont have values for "to" and "RequisitionID". I have not added [Required] to them. Is this possible? To POST and have those two null?
You should declare optional fields using a nullable type
public int? RequisitionID { get; set; }
To accept the null values you can use the following solution.
public int? RequisitionID { get; set; }
