Calculate sum of decimal values from child class and display in parent class in one to many relationships in asp.net core web api - sum
I am still new to asp.net core web api one to many relationships, I have two tables: Loan and loanHistories
Loan Model
public class Loan
{
[Key]
public int LoanID { get; set; }
[DataType(DataType.Currency)]
[Column(TypeName = "money")]
public decimal LoanAmount { get; set; }
[DataType(DataType.Currency)]
[Column(TypeName = "money")]
[Display(Name = "Loan Balance")]
private decimal _LoanBalance;
public decimal LoanBalance
{
get
{
return LoanAmount *interestRate;
}
set { _LoanBalance = value; }
}
[Display(Name = "Interest Rate")]
public decimal interestRate { get; set; }
[DataType(DataType.Date)]
[DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = true)]
[Display(Name = "Application Date")]
public DateTime ApplicationDate { get; set; }
[DataType(DataType.Date)]
[DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = true)]
[Display(Name = "Disbursement Date")]
public DateTime DisbursmentDate { get; set; }
[DataType(DataType.Date)]
[DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = true)]
[Display(Name = "Due Date")]
public DateTime DueDate { get; set; }
[Display(Name = "Defaulted")]
public bool Defaulted { get; set; }
[Display(Name = "Approved")]
public bool Approved { get; set; }
//Navigation property
public int CustomerID { get; set; }
public Customer customer { get; set; }
//public ICollection<LoanComments> loancomments { get; set; }
public ICollection<LoansHistories> loansHistories { get; set; }
}
LoanHistories model:
public class LoansHistories
{
[Key]
public int HistID { get; set; }
[DataType(DataType.Currency)]
[Column(TypeName = "money")]
[Display(Name = "Repaid Amount")]
public decimal RePaidIn { get; set; }
[DataType(DataType.Date)]
[DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = true)]
[Display(Name = "Repayement Date")]
public DateTime RepayementDateDate { get; set; }
[Display(Name = "No of paying interest only")]
public int NoOfPayinyingIntrestOnly { get; set; }
//Navigation properties
public int LoanID { get; set; }
public Loan loan { get; set; }
}
It generates the following Json data

Now I want to calculate the total sum of rePaidIn within loanHistories table and display in loan table Has TotalRepaidIn with heading [NotMapped]: I have tried from the following link .it seems close to answer my question but it does not
Here is my Controller
[HttpGet]
public async Task<ActionResult<IEnumerable<Loan>>> Getloans()
{
return await _context.loans.Include(lh => lh.loansHistories).ToListAsync();
}
Any solution will be highly appreciated. Thanks in advance
Here is a whole working demo:
Model:
public class Loan
{
[Key]
public int LoanID { get; set; }
[DataType(DataType.Currency)]
[Column(TypeName = "money")]
public decimal LoanAmount { get; set; }
[DataType(DataType.Currency)]
[Column(TypeName = "money")]
[Display(Name = "Loan Balance")]
private decimal _LoanBalance;
[Column(TypeName = "decimal(18,2)")]
public decimal LoanBalance
{
get
{
return LoanAmount * interestRate;
}
set { _LoanBalance = value; }
}
[Column(TypeName = "decimal(18,2)")]
[Display(Name = "Interest Rate")]
public decimal interestRate { get; set; }
//....
[Display(Name = "Approved")]
public bool Approved { get; set; }
//public ICollection<LoanComments> loancomments { get; set; }
public ICollection<LoansHistories> loansHistories { get; set; }
[NotMapped]
public decimal TotalRepaidIn { get; set; } //add this...
}
public class LoansHistories
{
[Key]
public int HistID { get; set; }
[DataType(DataType.Currency)]
[Column(TypeName = "money")]
[Display(Name = "Repaid Amount")]
public decimal RePaidIn { get; set; }
[DataType(DataType.Date)]
[DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = true)]
[Display(Name = "Repayement Date")]
public DateTime RepayementDateDate { get; set; }
[Display(Name = "No of paying interest only")]
public int NoOfPayinyingIntrestOnly { get; set; }
public int LoanID { get; set; }
public Loan loan { get; set; }
}
Controller:
public async Task<ActionResult<IEnumerable<Loan>>> Getloans()
{
var data = await _context.loans.Include(lh => lh.loansHistories).Select(l=>new Loan()
{
TotalRepaidIn = l.loansHistories.Select(lh=>lh.RePaidIn).Sum(),
loansHistories = l.loansHistories,
ApplicationDate = l.ApplicationDate,
Defaulted=l.Defaulted,
DisbursmentDate= l.DisbursmentDate,
DueDate= l.DueDate,
LoanID=l.LoanID,
Approved=l.Approved,
interestRate=l.interestRate,
LoanAmount=l.LoanAmount
}).ToListAsync();
return data;
}
Update:
A better way is to change your model like below:
using System.Linq; //import this namespace...
public class Loan
{
[Key]
public int LoanID { get; set; }
[DataType(DataType.Currency)]
[Column(TypeName = "money")]
public decimal LoanAmount { get; set; }
private decimal _TotalRepaidIn;
[NotMapped]
public decimal TotalRepaidIn
{
get { return loansHistories.Sum(sum => sum.RePaidIn); }
set { _TotalRepaidIn = value; }
}
//other properties
public ICollection<LoansHistories> loansHistories { get; set; } = new List<LoansHistories>();
}
Controller:
public async Task<ActionResult<IEnumerable<Loan>>> Getloans()
{
return await _context.loans.Include(lh => lh.loansHistories).ToListAsync();
}

[DisplayName("Detalles de Compra")]
public string ProposalDetails { get; set; }
[DataType(DataType.Date), DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:dd/MM/yyyy}")]
[DisplayName("Creado")]
public DateTime TimeStamp { get; set; }

how I define my model using lazyloading = true
How I define my model using lazyloading = true in MVC 4? I am trying to load my foreign keys. Now my query is coming null. In my web api query comes right.
I did not use the "virtual".
My Model:
[Key]
[DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)]
public int intClienteFornecedorId { get; set; }
[MaxLength(50)]
[Display(Name = "Nome:")]
[UniqueClienteFornecedorNome(ErrorMessage = "Já existe um Cliente ou Fornecedor cadastrado com esse Nome.")]
[Required(ErrorMessage = "É obrigatório informar o Nome.")]
public string strClienteFornecedorNome { get; set; }
[MaxLength(2)]
[Display(Name = "Pessoa:")]
public string strClienteFornecedorPessoa{ get; set; }
[ForeignKey("Estado")]
[Display(Name = "Estado:")]
public string strUFId { get; set; }
public virtual Estado Estado { get; set; }
[MaxLength(9)]
[Display(Name = "CEP:")]
public string strClienteFornecedorCEP { get; set; }
[MaxLength(70)]
[Display(Name = "Site:")]
public string strClienteFornecedorSite { get; set; }
[MaxLength(250)]
[Display(Name = "Observação:")]
public string strClienteFornecedorObservacao { get; set; }
[MaxLength(1)]
[Display(Name = "Situação:")]
public string strClienteFornecedorSituacao { get; set; }
[ForeignKey("Usuario")]
public int intUsuarioId { get; set; }
public virtual Usuario Usuario { get; set; }
public DateTime? dtClienteFornecedorDataAlteracao { get; set; }
public DateTime? dtClienteFornecedorDataCriacao { get; set; }
[NotMapped]
public bool ckbClienteFornecedor { get; set; }
[NotMapped]
public bool? hdMaisInformacoes { get; set; }
[NotMapped]
public bool? hdObservacao { get; set; }
public virtual ICollection<Contato> Contatos { get; set; }
public virtual ICollection<ClienteFornecedor_Contato> ClienteFornecedoresContatos { get; set; }
WEB API:
[System.ComponentModel.DataObjectMethodAttribute(System.ComponentModel.DataObjectMethodType.Select, false)]
public List<ClienteFornecedor> GetClientesFornecedoresByintUsuarioId(int intUsuarioId)
{
//Validate Input
if (intUsuarioId.IsEmpty())
return GetAllClienteFornecedor();
_DatabaseContext.ContextOptions.LazyLoadingEnabled = false;
return (from clienteFornecedor in _DatabaseContext.ClienteFornecedor
where clienteFornecedor.intUsuarioId == intUsuarioId
select clienteFornecedor).Include("Usuario").Include("UF").OrderBy(c => c.strClienteFornecedorNome).ToList();
}
In the web api returns two records, but in my web application the second record returns null why?
Could anyone help me please?
The second record is null, anyone know why?

MVC 4 EF5 Database First set Default Values in Partial Class
I'm new to MVC and trying to figure out how to set default values for partial classes. I have been searching for 2 days now, and can't get anything to work. Here is a supposed solution, but it doesn't work for me. I also tried the [DefaultValue(10)] data annotation.
Here is the auto generated partial class created from the edmx file
//------------------------------------------------------------------------------
// <auto-generated>
// This code was generated from a template.
//
// Manual changes to this file may cause unexpected behavior in your application.
// Manual changes to this file will be overwritten if the code is regenerated.
// </auto-generated>
//------------------------------------------------------------------------------
namespace OTIS.Models.Admin
{
using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
public partial class Company
{
public Company()
{
this.Facilities = new HashSet<Facility>();
}
public int CompanyID { get; set; }
[Required]
[Display(Name = "Company Name")]
public string CompanyName { get; set; }
public string Address1 { get; set; }
public string Address2 { get; set; }
public string City { get; set; }
public string State { get; set; }
public string PostalCode { get; set; }
public decimal ItemMargin { get; set; }
public decimal ServicesMargin { get; set; }
public decimal InvoiceTimeIncrement { get; set; }
public decimal CashDiscountPct { get; set; }
public decimal BaseServiceHourlyRate { get; set; }
public decimal HourlyPremiumRush { get; set; }
public decimal HourlyPremiumLate { get; set; }
public decimal HourlyPremiumCustomerMaterial { get; set; }
public int CreatedByID { get; set; }
public System.DateTime CreatedOn { get; set; }
public int ModifiedBy { get; set; }
public System.DateTime ModifiedOn { get; set; }
public virtual UserProfile UserProfile { get; set; }
public virtual UserProfile UserProfile1 { get; set; }
public virtual ICollection<Facility> Facilities { get; set; }
}
}
Here is my partial class I created to add annotations.
namespace OTIS.Models.Admin
{
[MetadataType(typeof(CompanyMD))]
public partial class Company
{
//public Company()
//{
// //private System.DateTime _currentDateTime = DateTime.Now;
// ////Set Default Values
// //CreatedByID = (int)Membership.GetUser().ProviderUserKey;
// //CreatedOn = _currentDateTime;
// //ModifiedBy = (int)Membership.GetUser().ProviderUserKey;
// //ModifiedOn = _currentDateTime;
//}
public string FullAddress
{
get
{
return this.City + ", " + this.State + " " + this.PostalCode;
}
}
public class CompanyMD
{
private System.DateTime _currentDateTime = DateTime.Now;
private int _currentUser = (int)Membership.GetUser().ProviderUserKey;
[Display(Name = "Company ID")]
public int CompanyID { get; set; }
[Required]
[Display(Name = "Company Name")]
public string CompanyName { get; set; }
[Display(Name = "Address")]
public string Address1 { get; set; }
[Display(Name = "Address 2")]
public string Address2 { get; set; }
public string City { get; set; }
public string State { get; set; }
[Display(Name = "Zip")]
public string PostalCode { get; set; }
[Display(Name = "Address")]
public string FullAddress { get; set; }
[Display(Name = "Material Margin")]
public decimal ItemMargin { get; set; }
[Display(Name = "Overtime Margin")]
public decimal ServicesMargin { get; set; }
[Display(Name = "Invoice Hour Increment")]
public decimal InvoiceTimeIncrement { get; set; }
private decimal _cashDiscountPct;
[Display(Name = "Cash Discount %")]
[DisplayFormat(DataFormatString = "{0:P2}")]
public decimal CashDiscountPct
{
get { return _cashDiscountPct; }
set { _cashDiscountPct = value/100; }
}
[Display(Name = "Base Hourly Rate ($/Hr)")]
[DataType(DataType.Currency), DisplayFormat(DataFormatString = "{0:C2}", ApplyFormatInEditMode = true)]
public decimal BaseServiceHourlyRate { get; set; }
[Display(Name = "Rush Premium ($/Hr)")]
[DataType(DataType.Currency), DisplayFormat(DataFormatString = "{0:C2}", ApplyFormatInEditMode = true)]
public decimal HourlyPremiumRush { get; set; }
[Display(Name = "Late Premium ($/Hr)")]
[DataType(DataType.Currency), DisplayFormat(DataFormatString = "{0:C2}", ApplyFormatInEditMode = true)]
[DefaultValue(75)]
public decimal HourlyPremiumLate { get; set; }
[Display(Name = "Cust Material Premium ($/Hr)")]
[DataType(DataType.Currency), DisplayFormat(DataFormatString = "{0:C2}", ApplyFormatInEditMode = true)]
public decimal HourlyPremiumCustomerMaterial { get; set; }
[Display(Name = "Created By")]
public int CreatedByID { get; set; }
//{
// get { return _currentUser; }
// set { _currentUser = value; }
//}
[Display(Name = "Created On")]
[DatabaseGenerated(DatabaseGeneratedOption.Computed)]
//[DataType(DataType.Date), DisplayFormat(DataFormatString = "{0:dd/MM/yyyy}", ApplyFormatInEditMode = true)]
public System.DateTime CreatedOn
{
get { return _currentDateTime; }
set { _currentDateTime = value; }
}
[Display(Name = "Modified By")]
public int ModifiedBy { get; set; }
//{
// get { return _currentUser; }
// set { _currentUser = value; }
//}
[Display(Name = "Modified On")]
public System.DateTime ModifiedOn
{
get { return _currentDateTime; }
set { _currentDateTime = value; }
}
}
}
}
And then in my controller, I instantiate a new instance of the class to initialize it, but the values I set don't get set.
//
// GET: /Company/Create
public ActionResult Create()
{
ViewBag.CreatedByID = new SelectList(db.UserProfiles, "UserId", "UserName");
ViewBag.ModifiedBy = new SelectList(db.UserProfiles, "UserId", "UserName");
Company newCompany = new Company();
return View(newCompany);
}
Sorry this is so late, but I just solved a similar scenario myself.
I think the problem is how you refer to the partial class. It should be an empty reference to the partial class with no code. EF uses this "declaration" to link your partial class to your metadata class. So, your metadata class should look like this:
namespace OTIS.Models.Admin
{
[MetadataType(typeof(CompanyMD))]
public partial class Company
{} // <-- note the close bracket!
public class CompanyMD
{
private System.DateTime _currentDateTime = DateTime.Now;
private int _currentUser = (int)Membership.GetUser().ProviderUserKey;
public string FullAddress
{
get
{
return this.City + ", " + this.State + " " + this.PostalCode;
}
