I have following Entity

```
[Table("classes")]
public class Class
{

    public int classID { get; set; }
    public Nullable<int> grade { get; set; }
    public string classname { get; set; }
    public Nullable<bool> Inactive { get; set; }
    public Nullable<int> total { get; set; }

    public virtual ICollection<Student> Students { get; set; }

    public Class()
    {}

}

```

This Entity is used at times by a stored procedure and at other times by entityframework (database first approach). Recently i added a field '**total**' that is used by stored procedure. Now the entity framework gives error 

> 
> 'unknown column total in field list'
> 
> 
> 

which is as expected. 

My question is that is there a way i can set a default value in the onModelCreated function for **total** column so that it ignores the model change exception? 

I am using EF6.
