Attaching validation to EF objects used in MVC controllers/views?

Question

We\'re throwing together a quick project (CRUD forms) and decided to skip view models and use EF entities directly in controllers and views. Since I\'m not used to this approach

Answer 1

This can be done using MetadataType attribute on the Ef generated classes. The EF generates partial classes. So those can be extended and attribute added to it. Then another "buddy class" can be written that can have member decoration. For example

[MetadataType(typeof(EFGeneratedClass_MetaData))]
public partial class EFGeneratedClass
{
}

public partial class EFGeneratedClass_MetaData
{
    [Required]
    [Display(Name="Member1 Display")]
    public string Member1 {get; set;}
}
