Extracting [] elements from form collection - mvc - should use icollection but have mix of types
- by bergin
hi there. have looked at Phil Haacks project on books at
http://haacked.com/archive/2008/10/23/model-binding-to-a-list.aspx
which has been useful, but I have a mix of data types.
I use a modelview so that i can have a mix of objects, in this case: Order (ie order.id, order.date etc), Customer, SoilSamplingOrder and a list of SoilSamplingSubJobs which is like this [0].id, [0].field, [1].id, [1].field etc
Perhaps I should be using ICollection instead of List? I had problems getting UpdateModel to work so I used an extract from collection method. the first 4 method calls : orderRepository.FindOrder(id); etc give the model the original to be edited. but after this point i'm a little lost in how to update the subjobs. I hope i have delineated enough to make sense of the problem.
[HttpPost]
public ActionResult Edit(int id, FormCollection collection)
{
Order order = orderRepository.FindOrder(id);
Customer cust = orderRepository.FindCustomer(order.customer_id);
IList<SoilSamplingSubJob> sssj = orderRepository.FindSubOrders(id);
SoilSamplingOrder sso = orderRepository.FindSoilSampleOrder(id);
try
{
UpdateModel(order, collection.ToValueProvider());
UpdateModel(cust, collection.ToValueProvider());
UpdateModel(sso, collection.ToValueProvider());
IList<SoilSamplingSubJob> sssjs = orderRepository.extractSSSJ(collection);
foreach (var sj in sssjs)
UpdateModel(sso, collection.ToValueProvider());
orderRepository.Save();
return RedirectToAction("Details", new { id=order.order_id});
}
catch
{
return View();
}
}
