So, Addresses has a PK of Id and a foreign key of EntityKey which references the Vendors table's Id, because Vendors have Addresses for their physical buildings.
When I query Vendors, I'm not able to return an associated Address.
Note: I don't want to change the schema.
[Table("EE.Address")]
public partial class Address {
[Key]
public Guid Id { get; set; }
[StringLength(50)]
public string Address1 { get; set; }
[StringLength(50)]
public string Address2 { get; set; }
[StringLength(50)]
public string City { get; set; }
[StringLength(5)]
public string State { get; set; }
[StringLength(30)]
public string PostalCode { get; set; }
[StringLength(10)]
public string CountryCode { get; set; }
public Guid EntityKey { get; set; }
[ForeignKey("EntityKey")]
public virtual Vendor Vendor { get; set; }
// EntityKey should be Vendor.Id
}
[Table("EE.Vendor")]
public partial class Vendor {
[Key]
public Guid Id { get; set; }
[StringLength(50)]
public string Name { get; set; }
[StringLength(50)]
public string AlternativeName { get; set; }
[StringLength(50)]
public string VendorCode { get; set; }
[StringLength(50)]
public string TaxId { get; set; }
public Guid VendorTypeKey { get; set; }
public Guid? ParentKey { get; set; }
[ForeignKey("Id")]
public virtual Address Address { get; set; }
}
Try this:
[Table("EE.Address")]
public partial class Address {
[Key]
public Guid Id { get; set; }
[StringLength(50)]
public string Address1 { get; set; }
[StringLength(50)]
public string Address2 { get; set; }
[StringLength(50)]
public string City { get; set; }
[StringLength(5)]
public string State { get; set; }
[StringLength(30)]
public string PostalCode { get; set; }
[StringLength(10)]
public string CountryCode { get; set; }
[ForeignKey("Vendor")]
public Guid EntityKey { get; set; }
public virtual Vendor Vendor { get; set; }
// EntityKey should be Vendor.Id
}
[Table("EE.Vendor")]
public partial class Vendor {
[Key]
public Guid Id { get; set; }
[StringLength(50)]
public string Name { get; set; }
[StringLength(50)]
public string AlternativeName { get; set; }
[StringLength(50)]
public string VendorCode { get; set; }
[StringLength(50)]
public string TaxId { get; set; }
public Guid VendorTypeKey { get; set; }
public Guid? ParentKey { get; set; }
[ForeignKey("Address")]
public Guid AddressId {get; set; }
public virtual Address Address { get; set; }
}

My target with the below mentioned classes is to make one DTOs class out of these classes and register AppUser in sqlite database. I use Identity core. I thank you for every body who has given me help on solving this problem.
By the way: is that possible to have virutal properties inside DTO classes? Other thing which i am struggling with is on how to handle the incoming user input (in this case DTO). I get the following error time and again Cannot implicitly convert type int to Backend.Data.Gender. I Cannot implicitly convert type Backend.Data.Work_Experience to System.Collections.Generic.List<Backend.Data.Work_Experience>

I am trying to use automapper to map between my entites db class and my view model. They have the same exact prop names but i get the error thrown saying unmapped members found. From what I understand if you have 1:1 Relationship you do not have to do the manual mapping in the config file. what am I missing here?

Thanks for the suggestions in the comments.
It appears, if the datetime column is set to allow null, then the datetime either has to be set to null or set to the correct format in order for sql datetime to work. Otherwise it throws the
"The conversion of a datetime2 data type to a datetime data type resulted in an out-of-range value.\r\The statement has been terminated."

I set the dates to null in my Entity objects, and entered a new entry to the database.
I have implemented asp .net application without Code first approach. now i want to build different system with existing database and code first.
public class EmployeeEntity
{
public int Id { get; set; }
public string ResourceCode { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public DateTime DateOfBirth { get; set; }
public int Gender { get; set; }
public int Status { get; set; }
public string NIC { get; set; }
}
now i want to add code first entities.
[Table("ExternalApplicantEntity")]
public class ExternalApplicantEntity
{
[Key]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int ApplicantID { get; set; }
//[ForeignKey("EmployeeEntity")]
//public int Created_By { get; set; }
//public virtual EmployeeEntity EmployeeEntity { get; set; }
public string NIC { get; set; }
public string Mobile { get; set; }
public string Institute { get; set; }
how i combine these codes?
In another question, I explain my goal to create 2 different types of users with different capabilities in my ASP.Net MVC 5 website. I wonder how I would be able to modify my current database models to hold the related information based on their type. My current models are as follows:
public class User : IUser
{
public User()
: this(String.Empty)
{
}
public User(string userName)
{
UserName = userName;
Id = Guid.NewGuid().ToString();
}
[Key]
public string Id { get; set; }
[Required]
public string UserName { get; set; }
[Required]
public string FirstName { get; set; }
[Required]
public string LastName { get; set; }
public string Phone { get; set; }
public string MobilePhone { get; set; }
[Required]
[DataType(DataType.EmailAddress)]
public string Email { get; set; }
public virtual IList<UserAddress> Addresses { get; set; }
}
public class Restaurant
{
[Key]
public int ID { get; set; }
[Required]
public string Name { get; set; }
public virtual IList<RestaurantAddress> Addresses { get; set; }
public virtual IList<RestaurantFood> Menu { get; set; }
public virtual IList<Review> Reviews { get; set; }
[DataType(DataType.Url)]
public string Website { get; set; }
[DataType(DataType.PhoneNumber)]
public string Phone { get; set; }
[DataType(DataType.PhoneNumber)]
public string Fax { get; set; }
[DataType(DataType.EmailAddress)]
public string Email { get; set; }
public int Seats { get; set; }
public double AverageRating { get; set; }
public double AveragePrice { get; set; }
}
One solution that comes to my mind is to move the additional info of the User class to another class and hold the foreign key for the related model in the basic user info class. Something like:
public class User : IUser
{
public User()
: this(String.Empty)
{
}
public User(string userName)
{
UserName = userName;
Id = Guid.NewGuid().ToString();
}
[Key]
public string Id { get; set; }
[Required]
public string UserName { get; set; }
public virtual ExtendedUser NormalUserInfo { get; set; }
public virtual Restaurant RestaurantInfo { get; set; }
}
public class ExtendedUser
{
[Required]
public string FirstName { get; set; }
[Required]
public string LastName { get; set; }
public string Phone { get; set; }
public string MobilePhone { get; set; }
[Required]
[DataType(DataType.EmailAddress)]
public string Email { get; set; }
public virtual IList<UserAddress> Addresses { get; set; }
}
public class Restaurant
{
[Key]
public int ID { get; set; }
[Required]
public string Name { get; set; }
public virtual IList<RestaurantAddress> Addresses { get; set; }
public virtual IList<RestaurantFood> Menu { get; set; }
public virtual IList<Review> Reviews { get; set; }
[DataType(DataType.Url)]
public string Website { get; set; }
[DataType(DataType.PhoneNumber)]
public string Phone { get; set; }
[DataType(DataType.PhoneNumber)]
public string Fax { get; set; }
[DataType(DataType.EmailAddress)]
public string Email { get; set; }
public int Seats { get; set; }
public double AverageRating { get; set; }
public double AveragePrice { get; set; }
}
and in controller:
User user = BuildUser();
ExtendedUser normal = BuildNormalUser();
Restaurant rest = BuildRestaurant();
if (model.Type == UserType.NormalUser)
user.NormalUserInfo = normal;
else
user.RestaurantInfo = normal;
However, I'm not sure that this is the right thing to do.
