I have a table Users:
I am using Entity Framework 6 to make the type configuration
public class UsersMapping : EntityTypeConfiguration<Users>
{
public UsersMapping()
{
HasKey(t => t.UserID);
Property(t => t.UserID).IsRequired();
ToTable("Users", "dbo");
Property(t => t.Id).HasColumnName("UserID");
}
}
and this is the Users class:
public class Users : EntityBase
{
public int UserID { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string UserName { get; set; }
public DateTime DateCreated { get; set; }
public byte[] Timestamp { get; set; }
public byte[] Password { get; set; }
public DateTime? DateActivated { get; set; }
public bool LockedOut { get; set; }
public string Address { get; set; }
public string City { get; set; }
public int? State { get; set; }
public string Zip { get; set; }
public string SecurityQuestion { get; set; }
public string SecurityAnswer { get; set; }
public string Email { get; set; }
public string PhoneNumber { get; set; }
public bool? ReportServiceAccount { get; set; }
public string CompanyName { get; set; }
public int? ILAC { get; set; }
public string BioFingerprint { get; set; }
public string Title { get; set; }
public string Squad { get; set; }
public byte[] SignatureFile { get; set; }
public byte? CETGroupID { get; set; }
public string TokenID { get; set; }
public int? Pin { get; set; }
public string RadioNr { get; set; }
}
public class EntityBase
{
public int Id { get; set; }
}
I am trying to set the Id field as primary because my repository pattern works using the field Id that is not present on this case in the table. But when I am trying to get the set of users I get this error:
The column name is invalid UserID1
The weird thing to me is the #1 that is at the end. What I am doing wrong?

I'm attempting to use AutoMapper for the first time. The GSMSite maps fine, but I get an error when trying to map the GSMUnit:
AutoMapperMappingException: Missing type map configuration or unsupported mapping.
Do I need to specify a relationship between GSMSite and GSMUnits?
Domain class:
public class ApplicationUser : IdentityUser
{
public string FirstName { get; set; }
public string LastName { get; set; }

I'm trying to seed a database using EF.
I have a table that holds products (phones) and a Category table that differentiates between different types of products.
public class Category
{
public int CategoryId { get; set; }
public string Name { get; set; }
public DateTimeOffset? CreationDate { get; set; }
public DateTimeOffset? UpdateDate { get; set; }
public virtual List<IProduct> Products{ get; set; }
public Category()
{
this.CreationDate = DateTimeOffset.UtcNow;
}
}
public interface IProduct
{
int ProductId { get; set; }
string Brand { get; set; }
string Model { get; set; }
decimal? Price { get; set; }
string Image { get; set; }
int CategoryId { get; set; }
Category Category { get; set; }
}
public class Phone: IProduct
{
public int ProductId { get; set; }
public int CategoryId { get; set; }
public Category Category { get; set; }
public string Brand { get; set; }
public string Model { get; set; }
public string network_technology { get; set; }
public string bands_2G { get;set; }
public string bands_3G{ get; set; }

public string RAM { get; set; }
public string primary_camera { get; set; }
public string secondary_camera { get; set; }
public string loud_speaker { get; set; }

I don't know what am I doing wrong but after I update the database from nuget console, a new Category record is created per seeded product(phone). That's exactly the opposite of what I want. I want all the phones to have one categoryId that refers to Phones category. does anyone know what's wrong?
Entity Type Configurations (fluent api):
public class CategoryConfiguration : EntityTypeConfiguration<Category>
{
public CategoryConfiguration()
{
ToTable("Categories");
HasKey(m => m.CategoryId);
}
}
public class PhoneConfiguration : EntityTypeConfiguration<Phone>
{
public PhoneConfiguration()
{
ToTable("Phones");
HasKey(m => m.ProductId);
}
}
Seed method:
protected override void Seed(BestPhone.Data.BestPhoneDbContext context)
{
context.Categories.AddOrUpdate(new Category(){Name = "Phones", CategoryId = 1});
...
//getting records from a csv file and holding them in an array.
var records = csvReader.GetRecords<Phone>().ToArray();
foreach (var record in records)
{
record.CategoryId = 1;
}
context.Phones.AddRange(records);
context.SaveChanges();
}
}
Try to add the next method on your CategoryConfiguration class:
public void Configure(EntityTypeBuilder<Category> builder)
{
builder
.HasMany(s => s.Products)
.WithOne(t => t.Category)
.HasForeignKey(t => t.CategoryId);
}
I'm not sure but it seems a system does not take into account your foreign key during seeding.
I'm not sure if this is possible or not, but I thought I would ask...
I have two database tables. One is a list of users pulled from Active Directory. The second table is a list of scheduled forwards. The relationship I would like to create would be...
public class AdObject
{
[Key]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int Id { get; set; }
public string ObjectType { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string DisplayName { get; set; }
public string DistinguishedName { get; set; }
public string PrimaryEmail { get; set; }
public string Alias { get; set; }
public string SamAccountName { get; set; }
public string PrimaryDisplay { get; set; }
public string CanonicalName { get; set; }
public string OU { get; set; }
public string CoreGroup { get; set; }
public string ForwardedTo { get; set; }
public bool? IsDisabled { get; set; }
public bool? IsForwarded { get; set; }
public bool? DeliverAndRedirect { get; set; }
public bool? DisableForwardAtLogon { get; set; }
public DateTime? DisableAtLogonAfter { get; set; }
public string Notify { get; set; }
public DateTime? LastLogon { get; set; }
public DateTime? LastApiLogon { get; set; }
public DateTime? LastCheck { get; set; }
// This isn't required. But if possible I would like this to be
// a relationship to another AdObject whos "PrimaryEmail" matches
// the "ForwardedTo" column of this AdObject. There will not always
// be a match though, so not too important just wondering if its possible.
public AdObject ForwardedToObject { get; set; }
// This would be a list of forwards where the "ForwardFrom"
// column matches the "PrimaryEmail" of this AdObject.
public ICollection<Forward> ScheduledForwards { get; set; }
= new List<Forward>();
// FYI... Technically ID,SamAccountName,PrimaryEmail,DistinguishedName,
// and CanonicalName are all unique. They could all be keys.
}
public class Forward
{
[Key]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int Id { get; set; }
public string ForwardFrom { get; set; }
public string ForwardTo { get; set; }
public bool? DeliverAndRedirect { get; set; }
public DateTime? StartTime { get; set; }
public DateTime? StopTime { get; set; }
public string Recurrence { get; set; }
public bool? DisableForwardAtLogon { get; set; }

public string StartJobStatus { get; set; }
public string StopJobStatus { get; set; }
public DateTime? StartJobCompleted { get; set; }
public DateTime? StopJobCompleted { get; set; }
public DateTime? StartJobCreated { get; set; }
public DateTime? StopJobCreated { get; set; }
public string StartReason { get; set; }
public string StopReason { get; set; }
// This would be the AdObject whos "PrimaryEmail" matches the
// "ForwardTo" column.
public AdObject ForwardToObject { get; set; }
// This would be the AdObject whos "PrimaryEmail" matches the
// "ForwardFrom" column.
public AdObject ForwardFromObject { get; set; }
}
I think I got it figured out. I was having a hell of a time understanding the logic behind relationships. I had a few misconceptions that I ironed out and after going through every YouTube video, PluralSight Course and Udemy course I could find it finally started to click. I usually don't have this much trouble teaching myself these things, but the misconceptions I had were pointing me in the wrong direction. In the end I only had to specify the keys and two relationships (conventions did the rest).
public class AdObject
{
[Key, Column(Order = 0)]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int Id { get; set; }
public string ObjectType { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string DisplayName { get; set; }
public string DistinguishedName { get; set; }
[Key, Column(Order = 1)]
public string PrimaryEmail { get; set; }
public string Alias { get; set; }
public string SamAccountName { get; set; }

public ICollection<Forward> ForwardSchedule { get; set; }

I have a the following classes
namespace MyClass.Models
{
public class Address : IIdentity
{
public string id { get; set; }
public DateTime updatedAt { get; set; }
public string user_id { get; set; }
public int building_number { get; set; }
public string street { get; set; }
public string area { get; set; }
public string county { get; set; }
public string country { get; set; }
public string postcode { get; set; }
public bool iscustomer { get; set; }
public bool islive { get; set; }
public string customer_id { get; set; }
public string store_id { get; set; }
public string phone_id { get; set; }
}
}
and
namespace MyClass.Models
{
public class User : IIdentity
{
public string id { get; set; }
public DateTime updatedAt { get; set; }
public string username { get; set; }
public string password { get; set; }
public bool isrestricted { get; set; }
public bool isbanned { get; set; }
public DateTime renewaldate { get; set; }
public string address_id { get; set; }
public string userlevel { get; set; }
}
}
What I am trying to do is create some test data to propagate through to my database so I can test my MVC5 website.
I am attempting to perform a look up on my instance of User within the Address class like so
user_id = context.User.FirstOrDefault(t=>t.address_id == id)
where id points to the id within the class I and trying instantiate.
VS2013 is saying that id does not exist in the current context which makes sense. Is there a way to do what I'm trying to achieve or am I better off setting the my _id from within the class itself and will that be okay when I run update-database from within the package manager console?
For example, the address class would become
namespace MyClass.Models
{
public class Address : IIdentity
{
public string id { get; set; }
public DateTime updatedAt { get; set; }
public string user_id { get {user_id = Users.FirstOrDefault(t=>t.address_id == id).id; } }
public int building_number { get; set; }
public string street { get; set; }
public string area { get; set; }
public string county { get; set; }
public string country { get; set; }
public string postcode { get; set; }
public bool iscustomer { get; set; }
public bool islive { get; set; }
public string customer_id { get {customer_id = Customers...;} }
public string store_id { get {store_id = Stores...;} }
public string phone_id { get {phone_id = Phones...;} }
}
}
