I am trying to create a new row in a table I have hosted in Azure SQL Database. My front end is AngularJS with C# in .NET as the back end.
Here is my code from the front end passing the object:
var insertTicket = function (newTicket) {
return $http.post("http://localhost:50412/api/tickets", JSON.stringify(newTicket))
.then(function (response) {
console.log(response);
console.log("Insert Successful");
return;
});
And here is my backend code that receives the data and tries to add to the database:
[Route("api/tickets")]
public HttpResponseMessage Post(Ticket t)
{
TicketsRepository.InsertTicket(t);
HttpResponseMessage response = Request.CreateResponse(HttpStatusCode.OK);
return response;
}
In TicketRepisitory:
public static void InsertTicket(Ticket tick)
{
var maxID = (from ticket in dataContext.Tickets
select ticket.id).Max();
var tick = new Ticket();
tick.id = maxID + 1;
dataContext.Tickets.Add(tick);
dataContext.SaveChanges();
}
And Here is my Ticket class:
public partial class Ticket
{
//Properties
public int id { get; set; }
public string title { get; set; }
public string customer { get; set; }
public string barcode { get; set; }
public string assignedTo { get; set; }
public string category { get; set; }
public string importance { get; set; }
public Nullable<System.DateTime> openDate { get; set; }
public Nullable<System.DateTime> dueDate { get; set; }
public Nullable<System.DateTime> closedDate { get; set; }
public string comments { get; set; }
public string condition { get; set; }
public Nullable<int> workHours { get; set; }
//Relationships
public Employee Employee { get; set; }
public Employee Employee1 { get; set; }
public Equipment Equipment { get; set; }
}
I think the issue is with Post() expecting a ticket object. I have tried searching for how to receive JSON data and use that for Ticket, but with out much luck.
My Problem is that I can not create a new row. No changes are reflected in my database.
You don't need to JSON.stringify your object when POSTing data with $httpin AngularJS, just pass the object itself as the second parameter, like this:
var insertTicket = function (newTicket) {
return $http.post("http://localhost:50412/api/tickets", newTicket)
.then(function (response) {
console.log(response);
console.log("Insert Successful");
return;
});
First there is no need to call JSON.stringify() method on newticket javascript object for second paramter of $http.post() method.
Then in the web api method write a parameter of type JObject with the name newTicket to receive the posted object, and use generic version of ToObject method to convert posted data to desired type. Don't forget to use [FromBody] attribute for the method parameter. the code for webapi looks like this:
[Route("api/tickets")]
public HttpResponseMessage Post([FromBody]JObject newTicket)
{
var t = newTicket.ToObject<Ticket>();
TicketsRepository.InsertTicket(t);
HttpResponseMessage = Request.CreateResponse(HttpStatusCode.OK);
return response;
}

I have page where I save user, contact and address details. The users could have multiple contact and address, So I have added the control to populate dynamically.
Form is working fine, except if any exception occurrs, the controller action return view with model.
This follows the structure of Model:
Model
public class UserModel
{
public UserDetail User { get; set; }
public IList<UserContact> Contact { get; set; }
public IList<UserAddress> Address { get; set; }
}
Contact Model :
public partial class UserContact
{
public int Id { get; set; }
public int UserId { get; set; }
public string ContactType { get; set; }
public string Mobile { get; set; }
public string Email { get; set; }
public bool IsActive { get; set; }
public virtual UserDetail UserDetail { get; set; }
}
Address Model
public partial class UserAddress
{
public int Id { get; set; }
public int UserId { get; set; }
public string AddressType { get; set; }
public string AddressName { get; set; }
public string AddressLine1 { get; set; }
public string AddressLine2 { get; set; }
public string City { get; set; }
public string State { get; set; }
public string PostCode { get; set; }
public bool IsActive { get; set; }
public virtual UserDetail UserDetail { get; set; }
}
When value return, the following function suppose to check the Contact and Address and then then populate each record in dynamic created input section in view.
<script type="text/javascript">
$(document).ready(function () {
AddDynamicData();
function AddDynamicData() {
var valuesContacts = eval('#Html.Raw(Json.Encode(Model.Contact))');
var valuesAddresses = eval('#Html.Raw(Json.Encode(Model.Address))');
if (valuesContacts != null) {
var iContact = 0;
$(valuesContacts).each(function () {
$("#divContact").append(GetDynamicContact(iContact++, valuesContacts.contactType, valuesContacts.mobile, valuesContacts.email));
});
}
if (valuesAddresses != null) {
var iAddress = 0;
$(valuesAddresses).each(function () {
$("#divAddress").append(GetDynamicAddress(iAddress++, valuesAddresses.addressType, valuesAddresses.addressName, valuesAddresses.addressLine1, valuesAddresses.addressLine2, valuesAddresses.city, valuesAddresses.state, valuesAddresses.postCode));
});
}
}
</script>
The Function does not work properly, It does create the field but does not populate the user input data into textbox... Please advise how to fix the same and how to populate the records in view....
Added the View after submitting the form
<Update>
#Updated New Code with function & added screenshot

I am working in service fabrics micro services , where i need to fetch record for an object. when I send request to API , it shows me empty lists while rest of the data is in place. while debugging I came to know that before returning to API controller my service object has all the data expected i.e lists has data , but when it comes back to web API the lists are empty.
After searching for solution over web I came to know that every time a request is to the API the lists are recreated , so it shows empty result. Any Solutions to come out of this problem?
Here is my piece of code.
The following Is the Web Api Method.
[HttpGet()]
[Route("edit/{readingListId}")]
[ProducesResponseType(typeof(List<GetReadingListDTO>), (int)HttpStatusCode.OK)]
[ProducesResponseType(typeof(List<GetReadingListDTO>), (int)HttpStatusCode.BadRequest)]
public async Task<IActionResult> GetReadingListById(int readingListId)
{
try
{
var readingList = await this._readingListService.GetReadingListByIdAsync(readingListId);
return Ok(readingList);
}
catch (Exception ex)
{
this._logger.LogError(ex.Message);
return BadRequest();
}
}
The following Is the Service Method.
public async Task<Domain.ReadingList> GetReadingListByIdAsync(int readingListId)
{
try
{
Domain.ReadingList readingList = await _repository.FindById(readingListId);
return readingList;
}
catch (Exception ex)
{
throw;
}
}
Moreover , This Is My Entity.
public class ReadingList : EntityBase, IAggregateRoot, IAggregateCreateRoot, IAggergateUpdateRoot, IAggregateDeleteRoot
{
public ReadingList()
{
this.Items = new List<ReadingListItem>();
this.Assignees = new List<ReadingListAssignee>();
}
public int Id { get; set; }
public EntityType EntityTypeId { get; set; }
public int EntityId { get; set; }
public string Title { get; set; }
public DateTime CompletionDate { get; set; }
public int ReminderDay { get; set; }
public string ReminderDayType { get; set; }
public bool SendReminder { get; set; }
public int CreatedBy { get; set; }
public DateTime CreatedDate { get; set; }
public int? UpdatedBy { get; set; }
public DateTime? UpdatedDate { get; set; }
public int? DeletedBy { get; set; }
public DateTime? DeletedDate { get; set; }
public bool? Deleted { get; set; }
public List<ReadingListItem> Items { get; private set; }
public List<ReadingListAssignee> Assignees { get; private set; }
}
Thanks!

The Issue Was Resolved , By Simply Changing The dll Versions.One Of The Service Had And Old Version While The Version Was Updated In The Other One.
Thanks For The Help.
I have an object in angularjs which I want to pass and map it to custom c# class in mvc controller. but whenever I am doing this class object is null completely.
$scope.Get = function () {
var EService = [{
id: $scope.Id,
servicename: $scope.ServiceName,
servicetype: $scope.ServiceType,
monthlyrental: $scope.MonthlyRental,
serviceremarks: $scope.ServiceRemarks,
servicestatus: $scope.status,
activationdate: $scope.ActivationDate,
deactivationdate: $scope.DeActivationDate
}];
$http.post('/TS/API/Insert', Service).then(function (res) {
debugger;
})
MVC Controller and Class:
[HttpPost]
public string Insert(ServicesMaster Service)
{
GIBCADBEntities gfientity = new GIBCADBEntities();
var record = "Sent"
return Json(record, JsonRequestBehavior.AllowGet);
} public class ServicesMaster
{
public string id { set; get; }
public string servicename { set; get; }
public string servicetype { set; get; }
public int? monthlyrental { set; get; }
public string serviceremarks { set; get; }
public byte servicestatus { set; get; }
public DateTime? activationdate { set; get; }
public DateTime? deactivationdate { set; get; }
}
The javascript variable/object "EService" is ok here, and when passing only the ServicesMaster object is created with null values and no data is mapped to it. I can send single string or any value from here but when sending a complete object its behaving like this.
You are passing an array from front end and fetching object from server end. just remove the "[" and "]" brace while set value to EService . Like :
$scope.Get = function () {
var Service = {};
Service = {
id: $scope.Id,
servicename: $scope.ServiceName,
servicetype: $scope.ServiceType,
monthlyrental: $scope.MonthlyRental,
serviceremarks: $scope.ServiceRemarks,
servicestatus: $scope.status,
activationdate: $scope.ActivationDate,
deactivationdate: $scope.DeActivationDate
};
$http.post('/TS/API/Insert', Service).then(function (res) {
debugger;
});
};
It should work now. :)
I have two simple models:
Book:
public class Book
{
public int BookID { get; set; }
public string Name { get; set; }
public string Author { get; set; }
public string Year { get; set; }
public string Publisher { get; set; }
public int GenreId { get; set; }
[ForeignKey("GenreId")]
public Genre Genre { get; set; }
}
and Genre
public class Genre
{
public Genre()
{
Books = new List<Book>();
}
public int GenreID { get; set; }
public string Name { get; set; }
public ICollection<Book> Books { get; set; }
}
With method from ApiController I get all data from table Books.
How can I get in javascript code Name of genre from table Genres using foreign key GenreId ?
I would like to write something like book.Genre.Name, but it does not work in js
You can try below code to serialize the object to return to frontend with json format:
var genre = new Genre();
JavaScriptSerializer js = new JavaScriptSerializer();
string data = js.Serialize(Genre);
Or in other way, you can use Json.NET for do that, this is a powerful json object convert lib.
I've configured my WebAPI ODATA service (using 5.0.0-rc1 for $expand and $select support) and everything seems to work fine but navigation properties.
The metadata does contain my navigation property (OpenPositions on Mandate) :
Then my breeze query is the following:
function search() {
var query = breeze.EntityQuery.from("Mandates").expand("OpenPositions").inlineCount();
return manager.executeQuery(query.using(service)).then(function (result) {
logger.info(result);
}).fail(function (error) {
logger.error(error);
});
}
The WebAPI controller :
[Queryable(AllowedQueryOptions= AllowedQueryOptions.All)]
public override IQueryable<Mandate> Get()
{
return new List<Mandate>() { new Mandate() {
Id = 1,
PolicyNumber = "350000000",
OpenPositions = new List<OpenPosition>(){
new OpenPosition(){ Id = 1, Amount = 2300, Mandate_Id = 1 },
new OpenPosition(){ Id = 2, Amount = 2100, Mandate_Id = 1 }
}},
new Mandate() {
Id = 2,
PolicyNumber = "240000000" ,
OpenPositions = new List<OpenPosition>(){
new OpenPosition(){ Id = 3, Amount = 2500, Mandate_Id = 2 },
new OpenPosition(){ Id = 2, Amount = 2100, Mandate_Id = 2}
}
} }.AsQueryable<Mandate>();
}
Nothing spectacular. But although my Mandate entities are coming back in the resultset, they do not have their OpenPositions collection.
As a test, if I add .select("OpenPositions") to my breeze query, then I get an error:
unable to locate property: OpenPositions on entityType: Mandate:#WebAPINoBreeze.Models
Why could that be ?
[EDIT]
query.entityType.NavigationProperties is an empty array, so that's probably a clue... It seems breeze could not build navigationproperties out of the metadata.
[EDIT]
foreign key added. problem still there:
public class Mandate
{
public int Id { get; set; }
public string PolicyNumber { get; set; }
public EStatus Status { get; set; }
public virtual List<OpenPosition> OpenPositions { get; set; }
}
public class OpenPosition
{
public int Id { get; set; }
public decimal Amount { get; set; }
[ForeignKey("Mandate")]
public int Mandate_Id { get; set; }
}
**[EDIT] **
For some reasons the [ForeignKey("Mandate")] attribute was removed at compile time (I think it's because the model class is generated. I've found a workaround and the metadata now contains the foreign key MandateId to Mandate in the OpenPositions :
You must define a foreign key as Breeze associations require FKs. http://www.breezejs.com/documentation/navigation-properties
[EDIT]
Your bi-directional association should look like this:
public class Mandate
{
public int Id { get; set; }
public string PolicyNumber { get; set; }
public virtual ICollection<OpenPosition> OpenPositions { get; set; }
}
public class OpenPosition {
public int Id { get; set; }
public decimal Amount { get; set; }
public int MandateId { get; set; }
public Mandate Mandate {get; set; }
}
