Need to deserialize a nested json array to server side array - asp.net-mvc

I have an array nested in an object in a JSON string which I need deserialized at the server:
var orderStatus = {"auth": "xxxx", "resourceType": "order.status", "idSet": "2980", "lifecycleEvent": "modified", "objects": { "orders": [ { "id": "2980", "statusId": "6" } ] }
I use Robert Koritnik's plugin like this:
$.ajax({url: "receiveJson", type: "POST", data: $.toDictionary(orderStatus) });
My .net class file is:
public class orders
{
public string Id { get; set; }
public string statusId { get; set; }
}
public class objects
{
public orders orders { get; set; }
}
public class OrderStatus
{
public string clientName { get; set; }
public string source { get; set; }
public string auth { get; set; }
public string resourceType { get; set; }
public string idSet { get; set; }
public string lifecycleEvent { get; set; }
public objects objects { get; set; }
}
my controller code is:
public JsonResult receiveJson(OrderStatus orderStatus)
So the orders object is the array. It works up to creating orders as an object but id and status id in the orders object are null.
I have no control over the JSON I will receive, it has to be in this format.
I am new to JSON and .NET MVC. Don't know how to specify server side orders object as an array.

Fixed it by slightly amending my server side classes:
public class order
{
public string Id { get; set; }
public string statusId { get; set; }
}
public class objects
{
public List<order> orders { get; set; }
}
public class OrderStatus
{
public string clientName { get; set; }
public string source { get; set; }
public string auth { get; set; }
public string resourceType { get; set; }
public string idSet { get; set; }
public string lifecycleEvent { get; set; }
public objects objects { get; set; }
}
So the "orders" class has been changed to "order". "objects.orders" property is amended to be a list.
Now the jsondata is deserialized all the way down.

How to transfer object value to modal class using ASP.Net MVC?

I'm having a hard time passing the value of an object to a model.
I wanted to pass the data from this obj to the model class
SingleTransactResponse obj = JsonConvert.DeserializeObject<SingleTransactResponse>(await response.Content.ReadAsStringAsync());
SaveTransaction(JsonConvert.SerializeObject(obj));
I used this function to get the data from the model and save it to the database
PayoutEntities payoutdb = new PayoutEntities();
public String SaveTransaction(payout_transaction model)
{
payoutdb.payout_transaction.Add(model);
payoutdb.SaveChanges();
return "Success";
}
SingleTransactResponse Class
public class SingleTransactResponse {
public String senderRefId { get; set; }
public String tranRequestDate { get; set; }
public String particulars { get; set; }
public List<Beneficiary> beneficiary { get; set; }
}
Beneficiary Class
public class Beneficiary
{
public String accountNumber { get; set; }
public String name { get; set; }
public List<Address> address { get; set; }
}
Address Class
public class Address
{
public String line1 { get; set; }
public String line2 { get; set; }
public String city { get; set; }
public String province { get; set; }
public String zipCode { get; set; }
public String country { get; set; }
}
payout_transaction class
public partial class payout_transaction
{
public string transid { get; set; }
public string batchid { get; set; }
public string senderRefId { get; set; }
public string requestDate { get; set; }
public string benefName { get; set; }
public string benefacctno { get; set; }
public string status { get; set; }
public string errdesc { get; set; }
public string transaction_fee { get; set; }
}
I'm just having a hard time converting the obj to the model. I've tried JsonConvert.SerializeObject(obj) but it only converts it to string. Is there any possible way to do this or any work around to solve this problem?
you can do like this
var payoutModel = new payout_transaction
{
senderRefId = obj.senderRefId,
requestDate = obj.tranRequestDate,
.... other properties
}
SaveTransaction(payoutModel);

Flatten Domain Class To ViewModel When Source Is Complex

I am using ValueInjecter to map domain classes to my view models. My domain classes are complex. To borrow an example from this question:
public class Person
{
public int Id { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public Address Address { get; set; }
}
public class Address
{
public int Id { get; set; }
public string City { get; set; }
public string State { get; set; }
public string Zip { get; set; }
}
// VIEW MODEL
public class PersonViewModel
{
public string FirstName { get; set; }
public string LastName { get; set; }
public int PersonId { get; set; }
public int AddressId { get; set; }
public string City { get; set; }
public string State { get; set; }
public string Zip { get; set; }
}
I have looked at FlatLoopInjection, but it expects the view model classes to be prefixed with nested domain model type like so:
public class PersonViewModel
{
public string FirstName { get; set; }
public string LastName { get; set; }
public int Id { get; set; }
public int AddressId { get; set; }
public string AddressCity { get; set; }
public string AddressState { get; set; }
public string AddressZip { get; set; }
}
The OP in the linked question altered his view models to match the convention expected by FlatLoopInjection. I don't want to do that.
How can I map my domain model to the original unprefixed view model? I suspect that I need to override FlatLoopInjection to remove the prefix, but I am not sure where to do this. I have looked at the source for FlatLoopInjection but I am unsure if I need to alter the Match method or the SetValue method.
you don't need flattening, add the map first:
Mapper.AddMap<Person, PersonViewModel>(src =>
{
var res = new PersonViewModel();
res.InjectFrom(src); // maps properties with same name and type
res.InjectFrom(src.Address);
return res;
});
and after that you can call:
var vm = Mapper.Map<PersonViewModel>(person);

mvc json to object value missing

I just converted json to c# class using json2csharp.com. Then trying to pass that json from view to my controller but problem is only "create_time" object value is garbing successfully no any other value is able to grab. Also please check my debug picture to get better idea. What mistake it can be?

I'll assume you're on dotnet core (maybe on a migrated project?) because the code you're posting doesn't have any issues on previous versions of asp.net mvc.
If that's the case, it turns out that on dotnet core the model binding behaviour has changed a little compared to previous versions.
If you want the solution quickly just decorate the parameter of your POST action with [FromBody] attribute. It should work.
[HttpPost]
public ActionResult InvoicePaid([FromBody]RootObject rootObject)
{
using (var ctx = new db_someEntities())
{
}
return Json("ok");
}
The story is a little longer though, and very interesting by the way. If you want the details, I've not found any better resource than this post from Andrew Lock.
UPDATE
I can confirm that if you add the [FromBody] on the action, (I've tested using a bare new asp.net core 2. web app project) it binds the model correctly.
Please let me know if you want me to provide the sources I've used so you can troubleshot from there.
Hope this helps!
Most probably the data being sent it not formatted properly
From comments it was indicated that the data was being sent like
$.post(hookUrl, { testJson: testJson }).done(function (data) { console.log(data); });
consider formatting the data and including the content type
var data = JSON.stringify(testJson); //replace content with your JSObject
$.post(hookUrl, data, null, "application/json")
.done(function (data) { console.log(data); });
Or using the longer syntax
var data = JSON.stringify(testJson); //replace content with your JSObject
$.ajax({
type: "POST",
url: hookUrl,
data: data,
dataType: "application/json",
success: function (data) { console.log(data); }
});
You need to use [FromBody], so MVC knows where to look for the data.
[HttpPost]
public ActionResult InvoicePaid([FromBody]RootObject rootObject)

MVC - how to use hyphen in model properties

I am getting json response from some server in format like:
[
{
"email":"john.doe#sendgrid.com",
"sg_event_id":"VzcPxPv7SdWvUugt-xKymw",
"sg_message_id":"142d9f3f351.7618.254f56.filter-147.22649.52A663508.0",

"url": "http://www.google.com/",
"purchase": "PO1452297845",
"Segmentid":"123456"
}]
In mvc controller action I am getting these response via model like:
[ValidateInput(false)]
[HttpPost]
public async Task<ActionResult> Index(ResponseModel[] rec)
{
}
My model is like:
public class ResponseModel
{
public int ReportId { get; set; }
public string raw { get; set; }
public int event_post_timestamp { get; set; }
public string SegmentId { get; set; }
public string url { get; set; }
public string type { get; set; }
public string status { get; set; }
public string attempt { get; set; }
public string useragent { get; set; }
public string ip { get; set; }
public string reason { get; set; }
public string response { get; set; }
public string newsletter { get; set; }
public string category { get; set; }
public string sg_message_id { get; set; }
public string sg_event_id { get; set; }
[Column("smtp-id")]
[DataMember(Name="smtp-id")]
[JsonProperty("smtp-id")]
public string smtp_id { get; set; }
public string email { get; set; }
[Column("event")]
[JsonProperty("event")]
[DataMember(Name = "event")]
public string #event { get; set; }
public int timestamp { get; set; }
}
In action I am getting all property initialized but not smtp-id. So please suggest me how can I map response "smtp-id" attribute to my model.
Create your own ActionFilterAttribute similar to what was done here
I know this is a really old post but I came across this and found that there are two things needed.
[JsonProperty(PropertyName = "message-id")] using Newtonsoft.Json and
a simple 'custom' model binder https://stackoverflow.com/a/34030497/2455159
Then any Json data object in can be bound to a model/ viewmodel in a controller accepting posted data like a webhook, that has invalid (at least a '-' ) character in property names/ attributes.

PagedList in MVC3 with IQueryable

I can't understand what i'm doing wrong. Every time I'm getting this error:
The entity or complex type 'BusinessLogic.CompanyWithDivisionCount' cannot be constructed in a LINQ to Entities query.
I need to get info from 'Company' table and divisions count of each company from 'Division' table, and then make PagedList. Here is my 'Company' table:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ComponentModel.DataAnnotations;
using BusinessLogic.Services;
using BusinessLogic.Models.ValidationAttributes;
namespace BusinessLogic.Models
{
public class Company
{
public Company()
{
Country = "US";
Status = true;
}
public int Id { get; set; }
[Required]
[UniqueCompanyName]
public string Name { get; set; }
public string Street { get; set; }
public string City { get; set; }
public string State { get; set; }
public int Zip { get; set; }
public string Country { get; set; }
public string ContactInfo { get; set; }
[Required]
public DateTime EffectiveDate { get; set; }
public DateTime TerminationDate { get; set; }
public bool Status { get; set; }
[Required]
public string URL { get; set; }
public string EAP { get; set; }
public string EAPCredentials { get; set; }
public string BrandingColors { get; set; }
public string Comments { get; set; }
}
}
Here is my domain model:
public class Company
{
public Company()
{
Country = "US";
Status = true;
}
public int Id { get; set; }
[Required]
[UniqueCompanyName]
public string Name { get; set; }
public string Street { get; set; }
public string City { get; set; }
public string State { get; set; }
public int Zip { get; set; }
public string Country { get; set; }
public string ContactInfo { get; set; }
[Required]
public DateTime EffectiveDate { get; set; }
public DateTime TerminationDate { get; set; }
public bool Status { get; set; }
[Required]
public string URL { get; set; }
public string EAP { get; set; }
public string EAPCredentials { get; set; }
public string BrandingColors { get; set; }
public string Comments { get; set; }
}
public class CompanyWithDivisionCount: Company // I'm using this
{
public int DivisionCount { get; set; }
}
Here is my controller:
public ActionResult CompaniesList(int? page)
{
var pageNumber = page ?? 1;
var companies = companyService.GetCompaniesWithDivisionsCount2();
var model = companies.ToPagedList(pageNumber, PageSize);
return View(model);
}
And here is my service part:
public IQueryable<CompanyWithDivisionCount> GetCompaniesWithDivisionsCount2()
{
return (from c in dataContext.Companies.AsQueryable()
select new CompanyWithDivisionCount
{
Id = c.Id,
Name = c.Name,
Status = c.Status,
EffectiveDate = c.EffectiveDate,
URL = c.URL,
EAP = c.EAP,
EAPCredentials = c.EAPCredentials,
Comments = c.Comments,
DivisionCount = (int)dataContext.Divisions.Where(b => b.CompanyName == c.Name).Count()
});
}
}
Thanks for help!!!
Creator of PagedList here. This has nothing to do with PagedList, but rather is an Entity Framework issue (I'm no expert on Entity Framework, so can't help you there). To confirm that this is true, write a unit test along the following lines:
[Test]
public void ShouldNotThrowAnException()
{
//arrange
var companies = companyService.GetCompaniesWithDivisionsCount2();
//act
var result = companies.ToList();
//assert
//if this line is reached, we win! no exception on call to .ToList()
}
I would consider changing you data model if possible so that instead of relating Companies to Divisions by name strings, instead use a properly maintained foreign key relationship between the two objects (Divisions should contain a CompanyID foreign key). This has a number of benefits (including performance and data integrity) and will almost certainly make your life easier moving forward if you need to make further changes to you app (or if any company ever decides that it may re-brand it's name).
If you create a proper foreign key relationship then your domain model could look like
public class Company
{
...
public virtual ICollection<Division> Divisions{ get; set; }
public int DivisionCount
{
get
{
return this.Divisions.Count()
}
}
...
}
