How to clone a Model using Entity Framework and ASP.Net Mvc 2
- by Picflight
I have the following class:
[MetadataType(typeof(PortalMetaData))]
[System.Web.Mvc.Bind(Exclude = "PortalId")]
public partial class Portal
{
public Portal()
{
this.Created = DateTime.Now;
}
}
public class PortalMetaData
{
[Required(ErrorMessage = "Portal name is required")]
[StringLength(50, ErrorMessage = "Portal name must be under 50 characters")]
public object PortalName { get; set; }
[Required(ErrorMessage = "Description is required")]
public object Description { get; set; }
}
I have a corresponding Table in the database Portal
I use the Portal table with a PortalController for the Site Admin to update the records in the Portal Table.
I want another user with a different Role (AsstAdmin) to be able to update this table as well.
To facilitate that I am thinking of creating a separate partial class that somehow links back to the Portal Model. This would allow me to display limited Fields for update by the AsstAdmin and I can display a different name for the Field as well.
How can I accomplish this task?
If I add the following class which inherits from Portal than I get an exception:
Unable to cast object of type
'Project1.Mvc.Models.Portal' to type
'Prpject1.Mvc.Models.Site'.
[MetadataType(typeof(SiteMetaData))]
public class Site : Portal
{
public Site() { }
}
public class SiteMetaData
{
[Required(DisplayName = "Site Description")]
public object Description { get; set; }
}
