Tips for extracting a $scope object containing various objects from a web API

What is the best way to pass an object that contains multiple objects within it, each with unique key-value pairs? Here is an example of the data structure:

[ Object, Object, Object, Object ]
0
:
Object
ProductID
:
"50"
__proto__
:
Object
1
:
Object
BrandID
:
24
__proto__
:
Object
2
:
Object
BrandID
:
26
__proto__
:
Object
3
:
Object
BrandID
:
20
__proto__
:
Object

One of these objects has a different key-value pair than the others. How can I extract this specific data from a Web API controller and how should I adjust my Model in the Web API project to accommodate it?

Answer №1

It appears that the array being sent to the Web API consists of objects with varying schemas, which can lead to errors and hinder proper use of ModelBinding.

Consider altering your object format to something like this:

$scope.myObject = {
    ProductID: 50,
    BrandIDs: [24, 26, 20]
};

By using this structure, you can successfully bind it to a strongly typed model in Web API.

public class MyModel {
    public int ProductID { get; set; }
    public List<int> BrandIDs { get; set; }
}

public IHttpActionResult Post(MyModel model) {
    var productId = model.ProductID;
    foreach(var brandId in model.BrandIDs) {
        DoSomething(brandId);
    }
    return Ok();    
}

To easily bind your JSON data in Web Api, create a corresponding class model. If you are working with an array of objects, you can define your model like this:

public void Execute(Model[] input)
{

}

....

public class Model
{
    public int? ProductId {get;set;}
    public int? BrandId {get;set;}
}

If you prefer to have an object containing an array, you can structure it like this:

public class ProductsContainer
{
     public Product[] Products {get;set;}
}
