    copied!<p>I'm having some doubts, maybe newbie doubts but I just got into ASP.NET MVC 4 Basically I would like to know the correct way of grabbing details of an Object inside a model. In this case Image inside Contractor.</p> <p>Model:</p> <pre><code>public class Contractor { [Key] public int ContractorID { get; set; } [Required] public string Name { get; set; } [Required] public string Address { get; set; } public Image Avatar { get; set; } } public class Image { [Key] public int ImageID { get; set; } [Required] public string File_name { get; set; } [Required] public byte[] File_data { get; set; } } public class DATACRUD : DbContext { public DbSet&lt;Contractor&gt; Companies { get; set; } public DbSet&lt;Image&gt; Images { get; set; } } </code></pre> <p>Controller:</p> <pre><code>private DATACRUD db = new DATACRUD(); public ActionResult GetContractorAvatar(int id) { Contractor contractor = db.Contractors.Find(id); if (contractor == null) { return HttpNotFound(); } Image avatar = contractor.Avatar; </code></pre> <hr> <p>Problem 1)</p> <p>avatar == null, but is not suppose to be because when I created the object Contractor, I added the image sucessfully (I checked in the DB and it is there)</p> <p>The solution I'm seeing is instead of having Image property in Contractor.cs model, I would just put a string property with the image key.</p> <hr> <p>Problem 2)</p> <p>Even If could grab the image key like I said in the previous problem, when I pass my mouse in Debug mode over private DATACRUD db = new DATACRUD ();</p> <p>db.Images is also empty...</p> <hr> <pre><code> return File(avatar.File_data, "image"); } </code></pre>
