I can't figure out why my child nodes are either null or have a count of 0, even though there's associated data in the db.
Parent Class "Project"
public partial class Project
{
public Project()
public int Id { get; set; }
public string Name { get; set; }
public int ProjectOwnerId { get; set; }
public int CurrentMilestoneId { get; set; }
public int StatusId { get; set; }
public virtual Milestone CurrentMilestone { get; set; }
public virtual ProjectStatus Status { get; set; }
public virtual ICollection<ProjectContact> Contacts { get; set; }
public virtual ProjectAddress Address { get; set; }
}
Child node property "CurrentMilestone" comes back null
public partial class Milestone
{
public int Id { get; set; }
public int MasterMilestoneId { get; set; }
public string Name { get; set; }
public virtual MasterMilestone MasterMilestone { get; set; }
public virtual ICollection<Project> Projects { get; set; }
}
Child node property "Contacts" comes back with an array of 0, even though there's valid matching data.
public partial class ProjectContact
{
public int Id { get; set; }
public int ProjectId { get; set; }
public int PersonId { get; set; }
public string Title { get; set; }
public virtual Person Person { get; set; }
public virtual Project Project { get; set; }
}
Using the HotTowel angular/breeze I'm running this..
return EntityQuery.from("Projects")
.orderBy(orderBy)
.expand("currentMilestone.masterMilestone, projectOwnerCompany, contacts, address")
.using(self.manager).execute()
.then(querySucceeded, self._queryFailed);
function querySucceeded(data) {
projects = data.results;
return projects;
}
Controller:
[HttpGet]
public IQueryable<Project> Projects()
{
return _contextProvider.QueryAllReadOnly<Project>();
}
What's weird is some of them work, like Status works but leaseStatus doesn't (not shown, setup the same way) without expanding it.
Just to add more info, if I run this against the API, ..../Projects?$expand=Status%2CCurrentMilestone%2CLeaseStatus%2CCurrentMilestone%2FMasterMilestone%2CContacts%2CContacts%2FPerson&
In Fiddler the child nodes aren't expanded.
Figured it out..
Change the Controller from ReadOnly to non-readonly.
From
[HttpGet]
public IQueryable<Project> Projects()
{
return _contextProvider.QueryAllReadOnly<Project>();
}
To
[HttpGet]
public IQueryable<Project> Projects()
{
return _contextProvider.QueryAll<Project>();
}

I have an entity relationship like this.
public class Provider
{
public int Id { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public virtual ICollection<ProviderPod> ProviderPods { get; set; } = new List<ProviderPod>();
}
public class ProviderPod
{
public int Id { get; set; }
public int ProviderId { get; set; }
public int PodId { get; set; }
public virtual Provider Provider { get; set; }
public virtual Pod Pod { get; set; }
}
public class Pod
{
public int Id { get; set; }
public string Name { get; set; }
public virtual ICollection<ProviderPod> ProviderPods { get; set; } = new List<ProviderPod>();
}
I need to order the 'Provider' entity by it's navigation property ProviderPods' "Name" separated by a comma. Something like this
IQueryable<Provider> entityQuery = context.Providers.AsQueryable();
//Need to enter Appropriate query below
entityQuery = entityQuery.OrderByDescending(x => string.Join(", ", x.ProviderPods.Select(y => y.Pod.Name)));
var list = entityQuery.Take(12).ToList();
What would be the best way to achieve this ordering?

Ticket Detail Class:
public class TicketDetail
{
[Key]
public int TicketDetailId { get; set; }
public int GenericOrderId { get; set; }
public int PartId { get; set; }
public int Quantity { get; set; }
public decimal? CustomerPrice { get; set; }
public string Status { get; set; }

public byte[] RowVersion { get; set; }
public virtual Part Part { get; set; }

public string Status { get; set; }
[Timestamp]
public byte[] RowVersion { get; set; }
public virtual Part Part { get; set; }
public virtual Order Order { get; set; }

Order Class:
public class Order : GenericOrder
{
public virtual ICollection<OrderDetail> OrderDetails { get; set; }
}
Ticket Class
public class Ticket : GenericOrder
{
public virtual ICollection<TicketDetail> TicketDetails { get; set; }
}
GenericOrderClass:
public abstract class GenericOrder

public int GenericOrderId { get; set; }
public string ProcessId { get; set; }

public string Phone { get; set; }
public string Message { get; set; }
public decimal Total { get; set; }
[Timestamp]
public byte[] RowVersion { get; set; }

and this is the controller class code
TryUpdateModel(order);
TryUpdateModel(ticket);
try
{
order.Date = DateTime.Now;
ticket.Date = DateTime.Now;
order.ProcessId = DateTime.Now.Ticks.ToString().Substring(12, 6);
ticket.ProcessId = order.ProcessId;
//Add the Order
storeDB.Orders.Add(order);
storeDB.Tickets.Add(ticket);
//Process the order
cart.CreateOrder(order);
cart.CreateTicket(ticket);
// Save all changes
storeDB.SaveChanges();
//return RedirectToAction("Complete",
// new { id = order.QuoteOrderId });
TempData["OrderSuccess"] = "Your order has been submitted successfully with the Process ID " + order.ProcessId;
TempData["OrderId"] = order.GenericOrderId;
TempData["Email"] = order.Email;
return RedirectToAction("Confirm");
}
catch (Exception e)
{
//Invalid - redisplay with errors
ModelState.AddModelError("", e.Message);
return View(order);
}
I have searched internet but couldn't find any solution.
Try saving Order and Ticket and after they are saved add Details to them.
I'm creating my first spa with angular and breeze. So for so good and i'm very happy with the progress I've made. But now I'm stuck on my editing and saving my entity product (example class below). When I edit a product i also call the related products, and I have a checkbox (on saving) that says "override related products with same info". But what is the best way to do this? Server side? Should i expand the model on the client side? Are there examples available?

Capture Changes of All Products in Clinent Jquery Array and send to Server Side..
Serverside change your controller method argument to IEnumerable products , so you can save all changes in Batch
If you want to update only change value use HttpPatch on server side and update changed value only
I need to create a price table system so I am going to create these three tables in my database.
PricingTable (ID, Name, ServiceID, Style)
PricingTablePackages (ID, PricingTable_ID, Title, Price, PricePerTime, Info, Flag, Link)
PricingTablePackagesFeatures (ID, PricingTablePackages_ID, Feature, Value, MoreInfo)
Here one PriceTable can hold more then one PricingTablePackages and one PricingTablePackage can hold more then one PricingTablePackagesFeature.
Is any way to design a better model? In a single database Table ?
I am going to create a MVC3 Model for those table so what is the best way to do this kind of DB Table in a MVC3 Model?
I would use public virtual variables for 'lazy-loading' values when you need them using Entity Framework:
(variable types may be off depending on exactly what you want for each variable)
public class PricingTablePackages
{
public int ID { get; set; }
public int PricingTableID { get; set; }
public virtual PricingTable PricingTable { get; set; }
public string Title { get; set; }
public decimal Price { get; set; }
public decimal PricePerTime { get; set; }
public string Info { get; set; }
public bool Flag { get; set; }
public string Link { get; set; }
}
public class PricingTablePackagesFeatures
{
public int ID { get; set; }
public int PricingTableID { get; set; }
public virtual PricingTable PricingTable { get; set; }
public string Feature { get; set; }
public string Value { get; set; }
public string MoreInfo { get; set; }
}
public class PricingTable
{
public int ID { get; set; }
public string Name { get; set; }
public int ServiceID { get; set; }
public virtual Service Service { get; set; } // if there is a Service class
public string Style { get; set; }
}
