i have tow model
personnes and diplomes
public class personne
{
public int Id { get; set; }
public string name { get; set; }
public virtual List<diplome> diplomes { get; set; }
}
public class diplome
{
public int Id { get; set; }
public string titre { get; set; }
public string description { get; set; }
public int personneId { get; set; }
public virtual personne personne { get; set; }
}
but I'can't display list off diplomes in ditails view
public ActionResult Details(int? id)
{
if (id == null)
{
return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
}
personne personne = db.personnes.Find(id);
personne.diplomes = db.diplomes.Where(d => d.personneId == id).ToList();
return View(personne);
}
in the view no acces to diplomes.titre
#foreach (var dep in model.diplomes)//error
{
<dd>
#Html.DisplayFor(dep.titre)
</dd>
}
Here is the DDL:
USE [Breaz]
GO
/****** Object: Table [dbo].[diplome] Script Date: 10/6/2016 1:33:31 PM ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON

GO
CREATE TABLE [dbo].[diplome](
[Id] [int] IDENTITY(1,1) NOT NULL,
[titre] [varchar](10) NULL,
[description] [varchar](10) NULL,
[personneId] [int] NULL,
CONSTRAINT [PK_diplome] PRIMARY KEY CLUSTERED
(
[Id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]

GO
CREATE TABLE [dbo].[personne](

GO
SET ANSI_PADDING OFF
GO

REFERENCES [dbo].[personne] ([Id])
GO
ALTER TABLE [dbo].[diplome] CHECK CONSTRAINT [FK_diplome_personne]
GO
You can then use entity framework (edmx) ADO.NET Entity Data Model. This generates the tables, as you specified:
public partial class personne
{
public personne()
{
this.diplomes = new HashSet<diplome>();
}
public int Id { get; set; }
public string name { get; set; }
public virtual ICollection<diplome> diplomes { get; set; }
}
public partial class diplome
{
public int Id { get; set; }
public string titre { get; set; }
public string description { get; set; }
public Nullable<int> personneId { get; set; }
public virtual personne personne { get; set; }
}
Here is the controller method:
public ActionResult Index2()
{
BreazEntities entity = new BreazEntities();
var perso = entity.personnes.ToList();
return View(perso);
}
Here is the view:
#{
Layout = null;
}
<!DOCTYPE html>
#model IEnumerable<Testy20161006.personne>
<html>
<head>
<meta name="viewport" content="width=device-width" />

#foreach (var item in pers.diplomes)

Problem
I have three model classes Student,Job and Alumni. I created EF DB first approah and I was able to save the Alumni details,But facing the error while saving the Student and Job details.Attached the relationship edmx file for reference.
Issue :
I am facing the error like "An exception of type 'System.Data.Entity.Validation.DbEntityValidationException' occurred in EntityFramework.dll but was not handled in user code" when crearing a new record for Job and Student.
Outcome:
I need to save new records for jobs and students from the EF,I was able to save alumni details
Clarification:
Is there any way to check the query being executed to SQL server from Visual Studio in entity framework other than profiler

The pattern of saving here matters because of db dependencies
Try This
[HttpPost]
[ValidateAntiForgeryToken]
//I removed the binding so the answer can be clearer, you can still include it but you need to pass the models. I don't know if you have passed them before
public ActionResult Create(Job job, Student student, Alumni alumni)
{
if (ModelState.IsValid)
{
//you will have to save in this pattern Alumni first, Job second, Student last
db.Alumni.Add(alumni);
db.SaveChanges();
//save the job
job.Alunmi_ID = alumni.Id
db.Job.Add(job)
db.SaveChanges()
//save the student
student.Job_ID = job.Id
db.Student.Add(student)
db.SaveChanges()
return RedirectToAction("Index");
}
ViewBag.Alumni_ID = new SelectList(db.Alumni, "Id", "AName", job.Alumni_ID);
return View(job);
}
I have two tables called Seminari and Predbiljezbe.
When I create a new data row in table Predbiljezbe, I want the row to take the primary key of table Seminari and insert it into table Predbiljezbe.
I'm hoping I made it clear, be mindful that since I am new to programming and would like help very much thank. I apologize for my bad English.
Here is my code:
Controller:
public ActionResult Create()
{
return View();
}
[HttpPost]
public ActionResult Create(Predbiljezbe predbiljezbePrijava)
{
if (ModelState.IsValid)
{
context.Predbiljezbes.Add(predbiljezbePrijava);
context.SaveChanges();
return RedirectToAction("Index");
}
return View(predbiljezbePrijava);
}
Entity model:
public partial class SeminariEntities1 : DbContext
{
public SeminariEntities1()
: base("name=SeminariEntities1")
{
}
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
throw new UnintentionalCodeFirstException();
}
public virtual DbSet<Predbiljezbe> Predbiljezbes { get; set; }
public virtual DbSet<Seminari> Seminaris { get; set; }
}
Predbiljezbe model:
public partial class Predbiljezbe
{
public int IdPredbiljezba { get; set; }
public string Ime { get; set; }
public string Prezime { get; set; }
public string Datum { get; set; }
public string Adresa { get; set; }
public string Email { get; set; }
public string Telefon { get; set; }
public bool Status { get; set; }
public Nullable<int> IdSeminara { get; set; }
public Nullable<int> BrojPolaznika { get; set; }
public virtual Seminari Seminari { get; set; }
}
Seminari model:
public partial class Seminari
{
[System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2214:DoNotCallOverridableMethodsInConstructors")]
public Seminari()
{
this.Predbiljezbes = new HashSet<Predbiljezbe>();
}
public int IdSeminar { get; set; }
public string Naziv { get; set; }
public string Opis { get; set; }
public System.DateTime Datum { get; set; }
public Nullable<bool> Popunjen { get; set; }
public string Predavač { get; set; }
[System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2227:CollectionPropertiesShouldBeReadOnly")]
public virtual ICollection<Predbiljezbe> Predbiljezbes { get; set; }
}
The way I do it is using double methods:
To insert into database and return Id
To insert dependent child using above Id
[HttpPost]
public ActionResult Create(Predbiljezbe predbiljezbePrijava)
{
if (ModelState.IsValid)
{
//add your first obj
context.Predbiljezbes.Add(predbiljezbePrijava);
context.SaveChanges();
//after saving in db its Id is automatically reflected in the object that you inserted
if(predbiljezbePrijava.Id != 0){
var seminariobj = new Seminari{ //insert your data }
// defining parentId into child
seminariobj.predbiljezbePrijavaId = predbiljezbePrijava.Id;
//save child obj
context.Seminari.Add(seminariobj);
context.SaveChanges();
}
return RedirectToAction("Index");
}
return View(predbiljezbePrijava);
}
I've tried your suggestion but i could not apply the solution to my problem,
Maybe there was an error in how I've set my tables and relations between them.
Here is my SQL query how i've set the tables in the database:
Seminari:
CREATE TABLE [dbo].[Seminari] (
[IdSeminar] INT IDENTITY (1, 1) NOT NULL,
[Naziv] NVARCHAR (MAX) NOT NULL,
[Opis] NVARCHAR (MAX) NULL,
[Datum] DATE NOT NULL,
[Popunjen] BIT NOT NULL,
[Predavač] NVARCHAR (50) NULL,
PRIMARY KEY CLUSTERED ([IdSeminar] ASC)
);
Predbilježbe:
CREATE TABLE [dbo].[Predbiljezbe] (
[IdPredbiljezba] INT IDENTITY (1, 1) NOT NULL,
[Ime] NVARCHAR (MAX) NOT NULL,
[Prezime] NVARCHAR (MAX) NOT NULL,
[Datum] NVARCHAR (MAX) NOT NULL,
[Adresa] NVARCHAR (MAX) NOT NULL,
[Email] NVARCHAR (MAX) NULL,
[Telefon] VARCHAR (MAX) NULL,
[Status] NVARCHAR (50) NULL,
[BrojPolaznika] INT NULL,
[IdSeminara] INT NULL,
CONSTRAINT [PK_Predbiljezbe] PRIMARY KEY CLUSTERED ([IdPredbiljezba] ASC),
CONSTRAINT [FK_Predbiljezbe_ToTable] FOREIGN KEY ([IdSeminara]) REFERENCES [dbo].[Seminari] ([IdSeminar])
);
Once again what i want is when i create new row in "Predbiljezbe" that column [IdSeminara] takes value of primary key [IdSeminar] from table "Seminari"!
i have primary table Student and foreign Table Academic
public partial class StudentInfo
{
public StudentInfo()
{
this.StudentCurrentAcademics = new HashSet<Academic>();
}
public int StudentInfoID { get; set; }
public Nullable<int> BranchID { get; set; }
public string ScholarID { get; set; }
public string Religion { get; set; }
public virtual ICollection<Academic> StudentCurrentAcademics { get; set; }
}
and my foregin table is
public partial class Academic
{
public decimal CurrentAcademicID { get; set; }
public Nullable<int> StudentInfoID { get; set; }
public Nullable<int> CourseID { get; set; }
public Nullable<int> StandardID { get; set; }
public virtual StudentInfo StudentInfo { get; set; }
}
I want to update both the table same time using
I initialized StudentInfo table object with Academic object.
I have set StudentInfoID in both tables.
Now updating it using
_context.Entry(StudentInfoObj).State = System.Data.Entity.EntityState.Modified;
_context.SaveChanges();
It's updating StudentInfo record in database but not updating Academic record.
Please try exactly as I do and it works. Your entity name and database will be different. The SaveChanges() will act as a transaction, so your updates will happened 'at the same time'.

This is the error i get when I'm trying to save data to my table.
Error:
An exception of type
'System.Data.Entity.Infrastructure.DbUpdateException' occurred in
EntityFramework.dll but was not handled in user code
Additional information: Unable to update the EntitySet
'CustormerD' because it has a DefiningQuery and no
<InsertFunction> element exists in the
<ModificationFunctionMapping> element to support the current
operation.
Controller Code:
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create([Bind(Include="custid,name,cell_No,address,date,time,serviceNo")] CustormerD custormerd)
{
if (ModelState.IsValid)
{
db.CustormerDs.Add(custormerd);
db.SaveChanges();
return RedirectToAction("Index");
}
return View(custormerd);
}
table code below:
public partial class CustormerD
{
public int custid { get; set; }
public string name { get; set; }
public Nullable<int> cell_No { get; set; }
public string address { get; set; }
public Nullable<System.DateTime> date { get; set; }
public Nullable<System.TimeSpan> time { get; set; }
public Nullable<int> serviceNo { get; set; }
}
sql code
CREATE TABLE [dbo].[CustormerD](
[custid] [int] IDENTITY(1,1) NOT NULL,
[name] [nchar](20) NULL,
[cell_No] [int] NULL,
[address] [nchar](20) NULL,
[date] [date] NULL,
[time] [time](7) NULL,
[serviceNo] [int] NULL
) ON [PRIMARY]
As per discussed in comment OP use .edmxfile.
So you can set primary key to your table like following:
USE [yourdatbase]
GO
/****** Object: Table [dbo].[CustormerD] Script Date: 26/09/2016 4:08:23 PM ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[CustormerD](
[custid] [int] IDENTITY(1,1) NOT NULL,
[name] [nchar](20) NULL,
[cell_No] [int] NULL,
[address] [nchar](20) NULL,
[date] [date] NULL,
[time] [time](7) NULL,
[serviceNo] [int] NULL,
CONSTRAINT [PK_CustormerD] PRIMARY KEY CLUSTERED
(
[custid] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
After set the primary key, you should update your .edmx model from the database.
The Entity Framework will only assume a primary key from your model if the name of the field is the name of the model + ID. Otherwise you will have to explicitly state which field to use as a primary key. For your model that would mean either changing the name of your primary key to:
public int CustomerDID { get; set; }
Entity framework would then automatically assume it as the primary key. Alternatively you label your primary key using [Key] as follows:
public partial class CustormerD
{
[Key]
public int custid { get; set; }
public string name { get; set; }
public Nullable<int> cell_No { get; set; }
public string address { get; set; }
public Nullable<System.DateTime> date { get; set; }
public Nullable<System.TimeSpan> time { get; set; }
public Nullable<int> serviceNo { get; set; }
}
I have a table contacts which has two phones for primaryphone and secondaryphone. Both of these have fields primaryphonetypeid and secondaryphonetypeid. These two columns reference the same table phonetype. No matter what I do, EF will not recognize the secondaryphonetypeid as a foreign key. I have even removed the primaryphonetypeid from my code and killed its foreign key constraint and it still says the secondaryphonetypeid does not exist.
[Table("PhoneType", Schema = "lkp")]
public class PhoneTypeEntity
{
[Key]
[Required]
[Column("PhoneTypeId")]
public int PhoneTypeId { get; set; }
[Column("PhoneTypeName")]
public string PhoneTypeName { get; set; }
}
public class ContactEntity

[Column("AccountId")]
public int? AccountId { get; set; }
