I know that this question has been asked like a hundred times, but I can't figure it out.
I have an ajax call like
function saveBox()
{
var postModel = createBoxPostModel();
showLoader();
$.ajax({
async: true,
type: 'post',
url: '#(Url.BuildAction<IncomingGoodsVerificationController>(x => x.SaveWorkUnitForBox(null, null, null)))',
data: { jsonPostModel: postModel, boxItemKey: boxItemKey, itemKey: itemKey },
success: function (data, status) {
...
},
error: function (jqXHR, textStatus, errorThrown) {
hideLoader();
displayErrorMessagePopup('Error in saving box! ', errorThrown, 'error-msgs');
}
});
}
and the controller method is like
[HttpPost]
public JsonResult SaveWorkUnitForBox(NewWorkUnitBoxModel postModel, string boxItemKey, string itemKey)
{
....
}
The NewWorkUnitBoxModel is
public class NewWorkUnitBoxModel
{
public NewWorkUnitBoxModel();
public string AlternativeWorkUnitNumer { get; set; }
public string Barcode { get; set; }
public int ChooseType { get; set; }
public decimal? GrossWeight { get; set; }
public long IdCompany { get; set; }
public long? IdPackagingType { get; set; }
public long? IdWorkUnitSubType { get; set; }
public decimal? NetWeight { get; set; }
public string Tone { get; set; }
public decimal? Volume { get; set; }
public long? WorkUnitNumber2 { get; set; }
}
and yet when the controller action is called is either null or the object has no value for each of its properties.
I tried several ways:
data: { jsonPostModel: postModel, boxItemKey: boxItemKey, itemKey: itemKey }
data: { jsonPostModel: JSON.stringify(postModel), boxItemKey: boxItemKey, itemKey: itemKey }
Putting all action parameters inside a request class
None of these worked. Client-side the model is loaded correctly, and by using ModelBinders I also looked inside the HtmlRequest and data had arrived on the server. I only solved with changing the type to a string and deserialize it inside the action.
How can I make it automatically deserialize the model?

I have a model class called ClientPackage and in my controller action method i receive a FormCollection from an ajax post call that i would like to convert it to the model class ClientPackage.
public class ClientPackage
{
public int DemandeId { get; set; }
public string NumeroRequette { get; set; }
public string NumeroModification { get; set; }
public int CasId { get; set; }
public string NumeroDossier { get; set; }
public string NomPatient { get; set; }
public string PrenomPatient { get; set; }
public string NiveauPriorite { get; set; }
public int NiveauPrioriteId { get; set; }
public Unite UniteDepart { get; set; }
public Unite UniteDestination { get; set; }
public Demandeur DemandeurDepart { get; set; }
public Demandeur DemandeurDestination { get; set; }
public ConditionTransport ConditionTransport { get; set; }
public Transport Transport { get; set; }
}
[HttpPost]
public string AjaxCall(FormCollection formData)
{
ClientPackage package = (ClientPackage)formData; //exception error
}
I would appriciate any help
Instead of trying to convert you can use the FromForm attribute and receive your model as a parameter.
[HttpPost]
public ActionResult CreateClientPackage([FromForm] ClientPackage clientPackage)
{
...
}
Here is how I post models with ajax.
<script>
function PostForm() {
var model = $('#your_form_id').serialize();
$.ajax({
url: '/YourController/AjaxCall',
type: 'POST',
data: model,
success: function (data) {
},
error: function (request, error) {
console.log("Request: " + JSON.stringify(request));
}
});
}
</script>
and in your controller.
[HttpPost]
public string AjaxCall(ClientPackage model)
{
//no need to cast the model to a ClientPackage
//ASP.NET mvc will do it for you as long as you send a serialized form that represents a ClientPackage object
}
Hope this helps!
I want to send data to a .net core 2.1 Action method. I collect the data with jQuery and send it with Ajax. When inspecting the payload the object I want to send is there. But the method wont recivie it. All the values are Null.
The Code:
C#
public class Customer
{
public int CustomerID { get; set; }
public string Name { get; set; }
public string OrgNumber { get; set; }
public string AdressLine1 { get; set; }
public string AdressLine2 { get; set; }
public string ZipCode { get; set; }
public string City { get; set; }
public string Country { get; set; }
public string Image { get; set; }
public int? StatusID { get; set; }
}
[HttpPost]
public async Task<IActionResult> Edit(Customer customer)
{
}
return View();
JavaScript
var customerObject = {
CustomerID: customerID,
Name: customerName,
OrgNumber: orgNumber,
AdressLine1: adressOne,
AdressLine2: adressTwo,
ZipCode: zipCode,
City: City,
Country: Country,
Image: customerImage,
StatusID: statusId
}
var url = `#Url.Action("Edit")`;
var postData = $.ajax({
url: url,
dataType: "json",
contentType: "application/json;",
data: { data: JSON.stringify(customerObject) },
method: 'POST',
async: true,
crossDomain: true
});
Payload from browser
data=%7B%22CustomerID%22%3A%2211%22%2C%22Name%22%3A%22Bambino+Kran%22%2C%22OrgNumber%22%3A%22456456131%22%2C%22AdressLine1%22%3A%22Lustikullagatan66%22%2C%22AdressLine2%22%3A%22%22%2C%22ZipCode%22%3A%2216578%22%2C%22City%22%3A%22H%C3%A4sselby%22%2C%22Country%22%3A%22%C3%96zbeckistan%22%2C%22Image%22%3A%22%22%2C%22StatusID%22%3A%221%22%7D
Payload deserialized:

Found this with a little bit of searching and solved it:
jObject
I'm trying to send a dropdownlists selected value to controller and retrieve json data back.
When I debug, parameter gets to controller nicely, values are retrieved nicely but after return part on console it says
"Failed to load resource: the server responded with a status of 500 (Internal Server Error)`"
This is my controller action: (in WebContentsController)
[HttpGet]
public JsonResult GetWebContentTypeDetails (int id)
{
var details = db.WebContentTypeDetail.Where(x=>x.WebContentTypeID == id).ToList();
return Json(details, JsonRequestBehavior.AllowGet);
}
this is JS part (printing it to console for testing)
$(document).ready(function () {
$("#WebContentTypeID").change(function () {
var ChangedID = $('#WebContentTypeID option:selected').val();
alert(ChangedID);
$.getJSON('/webcontents/GetWebContentTypeDetails/' + ChangedID, function (data) {
console.log(data);
})
});
});
EDIT:
WebContentTypeDetail model
public partial class WebContentTypeDetail
{
public int WebContentTypeDetailID { get; set; }
public int WebContentTypeID { get; set; }
public string DetailKey { get; set; }
public string Description { get; set; }
public Nullable<short> Rank { get; set; }
public virtual WebContentType WebContentType { get; set; }
}
WebContentType model
public partial class WebContentType
{
[System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2214:DoNotCallOverridableMethodsInConstructors")]
public WebContentType()
{
this.WebContent = new HashSet<WebContent>();
this.WebContentTypeDetail = new HashSet<WebContentTypeDetail>();
}
public int WebContentTypeID { get; set; }
public string DisplayName { get; set; }
public string CreatedByUserID { get; set; }
public System.DateTime CreateDate { get; set; }
public string LastEditedByUserID { get; set; }
public Nullable<System.DateTime> LastEditDate { get; set; }
[System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2227:CollectionPropertiesShouldBeReadOnly")]
public virtual ICollection<WebContent> WebContent { get; set; }
[System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2227:CollectionPropertiesShouldBeReadOnly")]
public virtual ICollection<WebContentTypeDetail> WebContentTypeDetail { get; set; }
}
You cannot directly return a entity list from context query result, because they are not serializable in most of cases, especially in your case: entities got a loop references.
you have 2 options:
var details = db.WebContentTypeDetail.Where(x=>x.WebContentTypeID == id)
map your result to anonymous object list:
return Json(details.select(x=>new {
//you data structure
}).ToList(), JsonRequestBehavior.AllowGet);
create your view model and mark it [Serializable], then return necessary data to client:
return Json(details.select(x=>new YourViewModel {
//you data structure
}).ToList(), JsonRequestBehavior.AllowGet);
Try this:
$(document).ready(function () {
$("#WebContentTypeID").change(function () {
var ChangedID = $('#WebContentTypeID option:selected').val();
alert(ChangedID);
$.getJSON('/webcontents/GetWebContentTypeDetails?id=' + ChangedID, function (data) {
console.log(data);
})
});
});
As parameter id should be passed as querystring. And if you're using mvc then url should be passed in #url.action so it must be
$(document).ready(function () {
$("#WebContentTypeID").change(function () {
var ChangedID = $('#WebContentTypeID option:selected').val();
alert(ChangedID);
var URL = #Url.Action("_GetWebContentTypeDetails", "webcontents");
$.getJSON(URL + '?id=' + ChangedID, function (data) {
console.log(data);
})
});
});
My model is
public class InvBrojeviModel
{
public int rb { get; set; }
public int id_ulaz_sredstava { get; set; }
public int? inv_broj { get; set; }
public string serijski_broj { get; set; }
public int id_sifra { get; set; }
}
I'm trying to pass this model to controller with an ajax call
var m = '#Html.Raw(Json.Encode(Model))';
$.ajax({
url: "/Ulazna_Dokumenta/InvBrojevi_Post",
type: 'POST',
data: JSON.stringify(m),
dataType: 'json',
success: function (data) {
alert("OK");
}
});
I can see the model is serialized. Serialized structure is
"[{\"rb\":6477,\"id_ulaz_sredstava\":308,\"inv_broj\":6477,\"serijski_broj\":null,\"id_sifra\":29},{\"rb\":6478,\"id_ulaz_sredstava\":308,\"inv_broj\":6478,\"serijski_broj\":null,\"id_sifra\":29},{\"rb\":6479,\"id_ulaz_sredstava\":308,\"inv_broj\":6479,\"serijski_broj\":null,\"id_sifra\":29},{\"rb\":6480,\"id_ulaz_sredstava\":308,\"inv_broj\":6480,\"serijski_broj\":null,\"id_sifra\":29}]":
But in controller the input parameter is NULL. The controller is
[HttpPost]
public ActionResult InvBrojevi_Post(IEnumerable<Magacin.Models.InvBrojeviModel> _invBrojeviModel)
{
return Json("test");
}
The input parameter _invBrojeviModel is NULL. Why?
Code
I can not send an array of javascript objects to the server.
ModelBinder standard does not recognize the format.
On my server I have classes:
public class PessoaViewModel
{
[HiddenInput(DisplayValue = false)]
public int Id { get; set; }
public string Nome { get; set; }
public string Tipo { get; set; }
public string CPF { get; set; }
public ICollection<TelefoneViewModel> Telefones { get; set; }
public ICollection<EnderecoViewModel> Enderecos { get; set; }
public ICollection<EmailViewModel> Emails { get; set; }
public PessoaViewModel Conjuge { get; set; }
}
public class TelefoneViewModel
{
[HiddenInput(DisplayValue = false)]
public int Id { get; set; }
[AdditionalMetadata("class", "span2")]
[AdditionalMetadata("placeholder", "Tipo")]
public string Tipo { get; set; }
[DataType(DataType.PhoneNumber)]
[AdditionalMetadata("class", "span2")]
public string Numero { get; set; }
[HiddenInput(DisplayValue = false)]
public int Ordem { get; set; }
}
I'm not listing the rest of the class because it is not yet used in the code!
My javascript
$.ajax
url: $(form).attr("action")
type: "POST"
error: (err, errType, errMessage) ->
console.error a.statusText
cache: false
data: ko.mapping.toJS(#, ignoreFunctionsMapping)
success: (data, txtStatus) -> console.log "OK!!?? On server maybe not!"

Question
As you can see, the post is being done and the values are correct.
But asp.net mvc does not fill correctly the Telefones object!
What am I doing wrong?
Your problem is because you are missing a ".", it should have the format:
Telefones[0].Id: 1
Telefones[0].Ordem: bli
