I have a slickgrid and am attempting to save its data back to the server.
When I breakpoint on the server, I can see the data in the Request.Form object, but I can't make it work with my object.
My data looks like...
[
{"id":"0","LineNumber":"","Detail":"MOT cost","Code":" ","Qty":"1","Est":" ","CustomerDamage":false,"Cost":"44.00","Value":"44.00","VAT":true,"SelfBillingLine":"False","DefectStatus":" "},
{"id":"62","LineNumber":"","Detail":"CRACKS IN Chassis","Code":"TLMA02","Qty":"1","Est":"","CustomerDamage":false,"Cost":"35.00","Value":"35.00","VAT":true,"SelfBillingLine":"False","DefectStatus":"Large repair"},
{"id":"63","LineNumber":"","Detail":"TEAR IN N/S CURTAIN","Code":"TLMA02","Qty":"1","Est":"","CustomerDamage":true,"Cost":"10.00","Value":"10.00","VAT":true,"SelfBillingLine":"False","DefectStatus":"Customer"}
]
I am posting with a button onclick...
$("#SBSave").click(function() {
debugger;
var details = JSON.stringify(defectrows);
save('SBDetail/SaveSBItem', details);
});
I have tried a number of things to receive the data, none of them work.
My controller...
[HttpPost]
public void SaveSBItem(SelfBillDetailList details, string Approve = "")
{
// Actions here.
}
My model...
Trying a number of things, neither work...
public class SelfBillDetailList
{
public IEnumerable<SelfBillingIncomingDetail> IncomingDetails { get; set; }
}
public class SelfBillingIncomingDetail
{
public int id { get; set; }
public string Code { get; set; }
public string LineNumber { get; set; }
public string Detail { get; set; }
public string Action { get; set; }
public string Qty { get; set; }
public string Est { get; set; }
public bool VAT { get; set; }
public bool CustomerDamage { get; set; }
public string Cost { get; set; }
public string Value { get; set; }
public DateTime Received { get; set; }
public string DefectStatus { get; set; }
public bool SelfBillingLine { get; set; }
}
So, I have tried an individual SelfBillingIncomingDetail and also a the SelfBillDetailList.
Neither work.
I have even sent an individual row, again, neither work.
I want to send it as a group, so it will be an array of SelfBillingIncomingDetail but nothing works.
Thank you for your help.
I have done it again... eventually found an answer after looking for ages.
Darin Dimitrov's answer in
Post an Array of Objects via JSON to ASP.Net MVC3
let me to the answer.
It seems that when sending the data, I need to give the array of data the same name as the property name in SelfBillDetailList, so...
var details = JSON.stringify({IncomingDetails : defectrows});
fixes it.

I'm using EF Code First. Now, I'm having a hard time figuring out how to write the LINQ to retrieve the data into my models in my Controller, to display them in a view. Basically, I am receiving a feed of HolterTest data, and I am trying to create a worklist for the people who do a bunch of specific tasks to process the HolterTest, allowing them to flag the tasks as they are completed, and provide status of where the individual tests are in the process The basic Task class is so they can add or alter steps in the process, with the displayOrder being the order in which tasks are done. A WorkTask is a specific instance of a task, allowing us to mark who completed it, and when. A WorkItem is the complex type that includes the HolterTest, the list of WorkTasks, and status information, including when the WorkTasks were all completed.
Model Classes:
public class HolterTest
{
public Int32 HolterTestID { get; set; }
public string PatientNumber { get; set; }
public string LastName { get; set; }
public DateTime RecordingStartDateTime { get; set; }
public System.Nullable<DateTime> AppointmentDateTime { get; set; }
}
public class Task
{
public Int32 TaskID { get; set; }
public string Name { get; set; }
public string Description { get; set; }
public Int32 DisplayOrder { get; set; }
public bool IsActive { get; set; }
}
public class WorkTask
{
public Int32 WorkTaskID { get; set; }
public Task Task { get; set; }
public bool IsCompleted { get; set; }
public System.Nullable<DateTime> CompletedDateTime { get; set; }
public string CompletedBy { get; set; }
}
public class WorkItem
{
public Int32 WorkItemID { get; set; }
public HolterTest HolterTest { get; set; }
public string Status { get; set; }
public List<WorkTask> WorkTasks { get; set; }
public bool IsStarted { get; set; }
public bool IsCompleted { get; set; }
public System.Nullable<DateTime> CompletedDateTime { get; set; }
}
Currently I have a business logic function that takes the list of HolterTests, finds the ones that don't have a WorkItem, and creates the WorkItems, associates the HolterTests including the WorkTasks, based on the current active list of Tasks.
My problem is how to write the LINQ to get all of the WorkItems (with their child items) for my WorkItemController so I can display the work to do in a View (WorkItems where IsCompleted = false) by PatientNumber, and make it possible to update WorkTasks for a particular WorkItem.
You want to access the related using it's navigation properties. Note that in your example, you haven't setup the navigation properties to be virtual. You should should update your model like this:
public class WorkItem
{
public Int32 WorkItemID { get; set; }
public virtual HolterTest HolterTest { get; set; }
public string Status { get; set; }
public virtual List<WorkTask> WorkTasks { get; set; }
public bool IsStarted { get; set; }
public bool IsCompleted { get; set; }
public System.Nullable<DateTime> CompletedDateTime { get; set; }
}
A simple function for accessing the work items by patient number is this:
IEnumerable<WorkItem> GetWorkIncompleteWorkItemsByPatient(string patientNumber)
{
var db = new YourContext();
return db.WorkItems.Where(wi => wi.IsCompleted == false && wi.HolterTest.PatientNumber == patientNumber);
}
Then to work on the related tasks, you would access it through the task, in this example if you knew the task ID:
var workTask = YourWorkItem.WorkTasks.FirstOrDefault(wt => wt.WorkTaskID == worktaskId);
You could look through all the tasks in the work item like this:
foreach (var workTask in YourWorkItem.WorkTasks)
{
//your logic here...
}

But starting here may suit better: The EF Main Site http://msdn.microsoft.com/en-us/data/ee712907

Essentially based on the POCO you have you could read per POCO and get the data that way.
However EF does a lot of heavy lifting if the POCOS have navigational properties and foreign keys defined. Worth revisiting the POCO definitions and Code-First patterns.
I have a class, which has 8 props / 8 columns in DB. But on a Edit page, i dont want to show the AddedDate or UserID field, since i dont want user to change it.
public class Voucher
{
public int ID { get; set; }
public string Title { get; set; }
public string SiteName { get; set; }
public string DealURL { get; set; }
public DateTime AddedDate { get; set; }
public DateTime? ExpirationDate { get; set; }
public string VoucherFileURL { get; set; }
public Guid UserID { get; set; }
}
Here is what I have for Edit controller:
// POST: /Voucher/Edit/5
[HttpPost]
public ActionResult Edit(Voucher voucher)
{
if (ModelState.IsValid)
{
string[] excludeProperties = { "AddedDate", "UserID" };
UpdateModel(ModelState, "", null, excludeProperties);
db.Entry(voucher).State = EntityState.Modified;
db.SaveChanges();
return RedirectToAction("Index");
}
return View(voucher);
}
On Edit page, once i click on submit, i got the following error: System.Data.SqlServerCe.SqlCeException: An overflow occurred while converting to datetime.
Seems like the AddedDate didn't get excluded from the view model and triggered the error.
Would you please let me know how to fix it? Thanks!
public ActionResult Edit([Bind(Exclude = "AddedDate")]Voucher voucher)
no luck either
You are still passing in Voucher which could contain that field in it. I'm not sure what you are trying to accomplish with the UpdateModel here if you are already passing in a Voucher object?
Pass in Voucher, set it to modified and save it. If you want to use whats in the database then you'll have to
Load the object from the database
UpdateModel and exclude the properties
Save your entity.
You could simply use a View Model and post that.
public class Voucher
{
public int ID { get; set; }
public string Title { get; set; }
public string SiteName { get; set; }
public string DealURL { get; set; }
public DateTime? ExpirationDate { get; set; }
public string VoucherFileURL { get; set; }
public Guid UserID { get; set; }
}
and then load up your object from the db":
var voucher = db.Vouchers.Where(o=>o.ID==voucherViewModel.Id);
//manually copy the fields here then save it
//copy
db.SaveChanges();
I have the properties for two entities in a ViewModel. The two entities are both related to one another, so for example, User and Posts. Each User can have multiple Posts, and Many Posts can belong to a single user (one-to-many).
The aim from my ViewModel is to allow the addition of a User and a Post on the same form. So my ViewModel looks something like this:
public class CreateVM
{
[Required, MaxLength(50)]
public string Username { get; set; }
[Required, MaxLength(500), MinLength(50)]
public string PostBody { get; set; }
// etc with some other related properties
}
In my Controller on the Create Method I have something like this:
[HttpPost]
public ActionResult Create(CreateVM vm)
{
if (ModelState.IsValid)
{
User u = new User()
{
Username = vm.Username,
// etc populate properties
};
Post p = new Post()
{
Body = vm.PostBody,
// etc populating properties
};
p.User = u; // Assigning the new user to the post.
XContext.Posts.Add(p);
XContext.SaveChanges();
}
}
It all looks fine when I walk through it through the Debugger, but when I try to view the post, its User relationship is null!
I also tried
u.Posts.Add(p);
UPDATE:
My Post class code is as follows:
public class Post
{
[Key]
public int Id { get; set; }
[Required, MaxLength(500)]
public string Body { get; set; }
public int Likes { get; set; }
[Required]
public bool isApproved { get; set; }
[Required]
public DateTime CreatedOn { get; set; }
[Required]
public User User { get; set; }
}
But that also did not work. What am I doing wrong?
Problem is that EF can not lazy load the User property because you haven't made it virtual.
public class Post
{
[Key]
public int Id { get; set; }
[Required, MaxLength(500)]
public string Body { get; set; }
public int Likes { get; set; }
[Required]
public bool isApproved { get; set; }
[Required]
public DateTime CreatedOn { get; set; }
[Required]
public virtual User User { get; set; }
}
If you know beforehand that you are going to access the User property of the post you should eager load the User related to the post.
context.Posts.Include("User").Where(/* condition*/);
I'm having trouble passing view information from my Get/Create action to my view. Here are my three model classes;
public class Competition
{
public int Id { get; set; }
public int CompetitionId { get; set; }
public string Name { get; set; }
public string Prize { get; set; }
}
public class CompetitionEntry
{
public int Id { get; set; }
public int CompetitionEntryId { get; set; }
public string Name { get; set; }
public string Email { get; set; }
public int CompetitionId { get; set; }
}
public class CompetitionEntryViewModel
{
public int Id { get; set; }
public Competition Competitions { get; set; }
public int CompetitionId { get; set; }
public string Name { get; set; }
public string Email { get; set; }
}
Here is my Get/Create action in CompetitionEntry Controller;
public ActionResult Create(int id)
{
CompetitionEntryViewModel competitionentryviewmodel = db.CompetitionEntriesView.Find(id);
return View(competitionentryviewmodel);
}
I know this doesn't work. The id parameter goes into the URL fine. How to I get access to my Competition class in th Get action? I need to be able to show the competion name on my Create Competition entry view.
Thanks in advance!
public ActionResult Create(int id)
{
var data = db.CompetitionEntriesView.Find(id);
CompetitionEntryViewModel competitionentryviewmodel = new CompetitionEntryViewModel();
competitionentryviewmodel.CompetitionName = data.Name;
return View(competitionentryviewmodel);
}
What you are trying to do is build an object graph and display it through a view model. In order to do this, you need to map your domain model(s) to your view model.
You can do the mapping yourself by writing a lot of code (re-inventing the wheel), or, you could consider using third party tools to do this for you. I recommend you use an AutoMapper as it is very simple to use imo.
The other problem is that your view model contains a domain model. This is likely to cause you a lot of headache in near future. If I were you, I would replace Competition with CompetitionViewModel.
I would also consider creating a view model for a list of competitions, i.e. CompetitionsViewModel. Look into partial views to see how you can display a list of competitions.
Good luck
Say I have the following:
(--> = 1 to many implemented as a collection in EF code-first)
Message --> UserMessage
Message --> Attachments
When I call the following:
var res = _ctx.DataContext.UserMessage.Where(x => x.UserId)
.Select(m => m.Message).ToList();
EDIT: added classes:
public class Message
{
public int MessageId { get; set; }
public ICollection<Attachment> Attachments { get; set; }
[Required]
public string Text { get; set; }
}
public class Attachment
{
public int AttachmentId { get; set; }
public int MessageId { get; set; }
public virtual Message Message { get; set; }
public string FileServerPath { get; set; }
}
public class UserMessage
{
public int UserMessageId { get; set; }
[Required]
public int MessageId { get; set; }
public Message Message { get; set; }
[Required]
public int UserId { get; set; }
public User User { get; set; }
}
I would expect the res variable to hold all the attachments but it is empty even if there are rows. What am I missing?
Your where condition doesn't make sense, I don't even think it compiles.
You say, you expect res to hold all attachments. Why should it? You don't even use Attachment anywhere in your query.
Without your actual classes, it is a bit hard to suggest the correct way, but I think it would be something like this:
var res = _ctx.DataContext.UserMessage.Where(x => x.UserId == currentUserId)
.SelectMany(m => m.Message.Attachments)
.ToList();
Now, res contains all attachments of all messages of the user with the id currentUserId.
I assumed a class layout like this:
class UserMessage
{
public int UserId {get;set;}
public Message Message {get;set;}
}
class Message
{
public IEnumerable<Attachment> Attachments {get;set;}
// Irrelevant for the query in its current form:
public IEnumerable<UserMessage> UserMessages {get;set;}
}
On the context it needs to be told to acquire the navigation properties with an include such as
_ctx.UserMessage.Include("Attachments")
.SelectMany( ... )
