Post complex model angularjs to web api

All we need is an easy explanation of the problem, so here it is.

Let’s say I have this models

public class HouseHolds
{
    public string Code { get; set; } 
    public List<HouseHoldBeneficiaries> HouseHoldBeneficiaries { get; set; }
}

public class HouseHoldBeneficiaries
{
    public Guid HouseHoldId { get; set; }
    public Guid BeneficiaryId { get; set; }
    public int HouseHoldRelationShipId { get; set; }
}

I want to post new HouseHold to database so I send the result from angularjs
but I Can’t bind List HouseHoldBeneficiaries.

Object

Code: "wer"
HouseHoldBeneficiaries:
HouseHoldRelationShipId: 2
BeneficiaryId: EAFC7940-5FAD-4C04-BC01-6D052BA5E711

But my HouseHoldBeneficiaries is always null in the model ??

How to solve :

I know you bored from this bug, So we are here to help you! Take a deep breath and look at the explanation of your problem. We have many solutions to this problem, But we recommend you to use the first method because it is tested & true method that will 100% work for you.

Method 1

Your HouseHoldBeneficiaries is a collection and thus needs to be send as json array like

{
Code:"wer",
HouseHoldBeneficiaries: [
{
 HouseHoldRelationShipId: 2,
 BeneficiaryId: EAFC7940-5FAD-4C04-BC01-6D052BA5E711
}
]
}

Note: Use and implement method 1 because this method fully tested our system.
Thank you 🙂
