How to show ddl in mvc VM

Question

I have following two tables.

CREATE TABLE [dbo].[CompanyProduct](
    [ID] [int] IDENTITY(1,1) NOT NULL,
    [StockName] [nvarchar](50) NOT NULL,
    [CompanyID] [int] NOT NULL,
    [CreatedDate] [datetime] NOT NULL,
    [CreatedByID] [int] NOT NULL,
    [StockDetail] [nvarchar](100) NULL,
 CONSTRAINT [PK_CompanyProduct] PRIMARY KEY CLUSTERED
(
    [ID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

GO

ALTER TABLE [dbo].[CompanyProduct]  WITH CHECK ADD  CONSTRAINT [FK_CompanyProduct_TPSCompany] FOREIGN KEY([CompanyID])
REFERENCES [dbo].[TPSCompany] ([ID])
GO

ALTER TABLE [dbo].[CompanyProduct] CHECK CONSTRAINT [FK_CompanyProduct_TPSCompany]
GO

and

 

CREATE TABLE [dbo].[TPSCompany](
    [ID] [int] IDENTITY(1,1) NOT NULL,
    [CompanyName] [nvarchar](100) NOT NULL,
    [ContactNumber] [nvarchar](50) NOT NULL,
    [DepartmentID] [tinyint] NOT NULL,
    [CreatedDate] [datetime] NOT NULL,
    [CreatedByID] [int] NOT NULL,
 CONSTRAINT [PK_TPSCompanies] PRIMARY KEY CLUSTERED
(
    [ID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

GO

ALTER TABLE [dbo].[TPSCompany]  WITH CHECK ADD  CONSTRAINT [FK_TPSCompanies_Department] FOREIGN KEY([DepartmentID])
REFERENCES [dbo].[Department] ([ID])
GO

ALTER TABLE [dbo].[TPSCompany] CHECK CONSTRAINT [FK_TPSCompanies_Department]
GO

 and using DB first approach , I have created classes of these tables.

 

for my use I have created a viewmodel with followings code

public class CompanyProductVM
    {

        public int ID { get; set; }

        [Required]
        [Display(Name = "Stock Name")]
        [DataType(DataType.Text)]

        public string StockName { get; set; }

        public int CompanyID { get; set; }
        [Required]
        [Display(Name = "Created Date")]
        [DataType(DataType.DateTime)]

        public System.DateTime CreatedDate { get; set; }


        public int CreatedByID { get; set; }
        [Required]
        [Display(Name = "Stock Detail")]
        [DataType(DataType.Text)]


        public string StockDetail { get; set; }

        public virtual TPSCompany TPSCompany { get; set; }
    }

and I have CompanyProduct.cs as follow.

 

public partial class CompanyProduct
   {
       public int ID { get; set; }
       public string StockName { get; set; }
       public int CompanyID { get; set; }
       public System.DateTime CreatedDate { get; set; }
       public int CreatedByID { get; set; }
       public string StockDetail { get; set; }

       public virtual TPSCompany TPSCompany { get; set; }
   }

when I tried to generate Controller using scaffolding with EF.I am unable to get ddl for company as I want to select company agaisnt each company.this simpily create Controller.and if i want to change TPSCOMPANY to IEnum or collection then it send error that unable to get metadata for the application.
