Adding Child to an existing parent in Webapi odata controller

I using Odata Webapi with EF6 and my models are as below

public class Company
{

Public Company()
{
Products = new List<Product>();

}
[Key]
public int Id { get; set; }

[Required]
public string Name { get; set; }

public List<Product> Products { get; set; }
}
public class Product
{
    [Key]
    public int Id { get; set; }

    [Required]
    public string Name { get; set; }

}

I need to expose an end point to add product/s to an existing Company. the end point has to be something like below.

Post: ~odata/Company(1)/Products with body as List of products json.
body:[{"Name":"Product1"},{"Name":"Product2"}]

I would suggest using an bound ODataAction for this purpose. You would need to pass in a DTO containing a list of Products.

An example for DTO would be:

public class CreateProductsDTO
{
 List<Product> Products { get; set; }
}

Then you would need to register an bound action to Company controller:

var action = builder.EntityType<Company>().Action("AddProducts");
action.Parameter<CreateProductsDTO>("Value");

In the controller you need to define an action like:

[HttpPost]
public async Task<IHttpActionResult> AddProducts([FromODataUri] Guid key, ODataActionParameters parameters)
{
  //read parameter from ODataActionParameters 
  var createProducts = parameters["Value"] as CreateProductsDTO;

  //Process information
}

The request for this would look like this:

Post: ~odata/Company(1)/AddProducts
body:
{ "Value" : {
"Products" : 
[{"Name":"Product1"},{"Name":"Product2"}]
}
}

Hope this helps. Regards, Mihai
