Insert new Entity with one to many relationship not creating records in both tables

manpreet Best Answer 2 years ago

I'm using MVC5 and EF6 Code First to create a new Company entity that can have many Contactentities. However, only the Company record is being written to the database.

Models:

public class Company
{
    public virtual int CompanyId { get; set; }

    [Required]
    public virtual string Name { get; set; }

    [Required]
    public virtual Address Address { get; set; }

    [Required]
    public virtual string Phone { get; set; }

    public virtual string Email { get; set; }

    // can have many Contacts
    public virtual IEnumerable<Contact> Contacts { get; set; }
}

public class Contact
{
    public virtual int ContactId { get; set; }

    [Required]
    public virtual string Title { get; set; }

    [Required]
    public virtual string Forename { get; set; }

    [Required]
    public virtual string Surname { get; set; }

    [Required]
    public virtual string Phone { get; set; }

    public virtual string Email { get; set; }

    // belongs to one Company
    public virtual Company Company { get; set; }
}

Controller:

    [HttpPost]
    [ValidateAntiForgeryToken]
    public async Task<ActionResult> Create_POST([Bind(Include = "CallerType,Name,Address,Phone,Email,Contacts")] CompanyViewModel viewModel)
    {
        if (ModelState.IsValid)
        {
            // tried commented code to make sure it wasn't a problem with my repository and contact records aren't saved to database...

            //var context = new EfDbContext();

            //var company = new Company
            //{
            //    Name = viewModel.Name,
            //    Phone = viewModel.Phone,
            //    Address = viewModel.Address,
            //    Email = viewModel.Email
            //};

            //context.Companies.Add(company);

            //var contact = new Contact
            //{
            //    Company = company,
            //    Title = "mr",
            //    Forename= "f",
            //    Surname = "s",
            //    Phone = "132"
            //};

            //var contact2 = new Contact
            //{
            //    Company = company,
            //    Title = "mr",
            
                                                

                                                                                                        
                                                    
                                                
                                                


                                                    

                                                        
                                                            0
                                                            views 

                                                            0
                                                                likes 
                                                            
                                                            

                                                            0
                                                            shares
