Jestem nowym ASP.NET MVC i EF nadzieją nie jest to głupie pytanieASP.NET MVC/Entity Framework Błąd - Nieprawidłowa nazwa kolumny 'Environment_Id'
Kiedy mijam modelu, aby zobaczyć Dostaję ten błąd - Szczegóły wyjątku: System.Data.SqlClient.SqlException: Niepoprawna nazwa kolumny "Environment_Id".
Tabela modeli lub bazy danych ma właściwość o tej nazwie. Czy ktoś mógłby mnie o tym poinformować ?.
**Here is the Version Model Class**
public partial class Version
{
public Version()
{
this.ProfileVersions = new List<ProfileVersion>();
this.ServerInfoes = new List<ServerInfo>();
}
public int Id { get; set; }
public string Number { get; set; }
public string Tag { get; set; }
public string Owner { get; set; }
public string Approver { get; set; }
public string Description { get; set; }
public virtual ICollection<ProfileVersion> ProfileVersions { get; set; }
public virtual ICollection<ServerInfo> ServerInfoes { get; set; }
}
**Profile Version Class**
public partial class ProfileVersion
{
public ProfileVersion()
{
this.PlatformConfigurations = new List<PlatformConfiguration>();
}
public int Id { get; set; }
public int ProfileId { get; set; }
public int EnvironmentId { get; set; }
public int VersionId { get; set; }
public Nullable<bool> Locked { get; set; }
public string LockedBy { get; set; }
public string Comments { get; set; }
public Nullable<int> Active { get; set; }
public virtual Environment Environment { get; set; }
public virtual ICollection<PlatformConfiguration> PlatformConfigurations { get;
set; }
public virtual PlatformProfile PlatformProfile { get; set; }
public virtual Version Version { get; set; }
}
**ServerInfo**
public partial class ServerInfo
{
public ServerInfo()
{
this.PlatformConfigurations = new List<PlatformConfiguration>();
}
public int Id { get; set; }
public string ServerName { get; set; }
public int ProfileId { get; set; }
public int VersionId { get; set; }
public int EnvironmentId { get; set; }
public string ServerType { get; set; }
public Nullable<short> Active { get; set; }
public string Domain { get; set; }
public string Location { get; set; }
public string IP { get; set; }
public string Subnet { get; set; }
public string Gateway { get; set; }
public Nullable<int> VLan { get; set; }
public string DNS { get; set; }
public string OS { get; set; }
public string OSVersion { get; set; }
public string Func { get; set; }
public Nullable<short> IISInstalled { get; set; }
public string ADDomainController { get; set; }
public string ADOrganizationalUnit { get; set; }
public string ADGroups { get; set; }
public string LastError { get; set; }
public Nullable<System.DateTime> LastUpdate { get; set; }
public virtual Environment Environment { get; set; }
public virtual ICollection<PlatformConfiguration> PlatformConfigurations { get;
set; }
public virtual PlatformProfile PlatformProfile { get; set; }
public virtual Version Version { get; set; }
public virtual VMConfiguration VMConfiguration { get; set; }
}
**Controller Code-**
public ViewResult Index(string id)
{
var profileVerList = from ver in _context.Versions
where !(from pfv in _context.ProfileVersions
select pfv.VersionId).Contains(ver.Id)
select ver;
var bigView = new BigViewModel
{
VersionModel = profileVerList.ToList(),
};
return View(model: bigView);
}
**In the View where the exception is thrown**
@Html.DropDownList(
"SelectedVersionID",
new SelectList(
Model.VersionModel.Select(x => new { Value = x.Id, Text = x.Number}),
"Value",
"Text"
)
)
Czy ProfileVersion lub ServerInfo mają właściwość środowiska? –
Tak -they public int EnvironmentId {get; zestaw; } @Olav Nybø – user2696668
