ASP.NET Core AJAX POST not returning error, however, not saving data-CodePudding

I am using a button OnClick event to try and save a record to a database using AJAX in ASP.NET Core. The function is not returning an error, however, the data is not being saved. I am just trying to test with hard coded data first. A record with AdapollingProjectProcessStatusId = 1 exists in the database.

function SendHtmlEditorValueToController(data) {
    $.ajax({
        type: 'POST',
        url: '@Url.Action("AJAXPost", "LiveAdapollingProjectProcessStatus")',
        contentType: "application/json", 
        data: JSON.stringify({ "id": 1, "status": 'test'}),
        dataType: 'json',
        success: () => {
          console.log("value is sent");
        },
        error: (error) => {
            console.log(JSON.stringify(error));
        }
    });


}

LiveAdapollingProjectProcessStatusController:

    [HttpPost]
    public JsonResult AJAXPost(int id, string status)
    {
        LiveAdapollingProjectProcessStatus processstatus = new LiveAdapollingProjectProcessStatus
        {
            AdapollingProjectProcessStatusId = id,
            AdapollingProjectProcessStatus = status
        };

        //save it in database
        return Json(processstatus);
    }

LiveAdapollingProjectProcessStatus.cs:

    namespace CPSPMO.Models.PMO
    {
        public partial class LiveAdapollingProjectProcessStatus
        {
            public int AdapollingProjectProcessStatusId { get; set; }
            public string AdapollingProjectProcessStatus { get; set; }
        }
    }

Please let me know if you are able to help me with this AJAX Post.

Thanks

Not sure how do you store it to the database, but the way you pass parameter to backend by ajax should be like below:

function SendHtmlEditorValueToController(data) {
    $.ajax({
        type: 'POST',
        url: '@Url.Action("AJAXPost", "LiveAdapollingProjectProcessStatus")',
        //contentType: "application/json",      //remove this... 
        data:{ "id": 1, "status": 'test'},      //modify here...
        dataType: 'json',
        success: () => {
            console.log("value is sent");
        },
        error: (error) => {
            console.log(JSON.stringify(error));
        }
    });
}

After reviewing the comments regarding missing code for saving the data in the database, I modified the controller:

    [HttpPost]
    public JsonResult AJAXPost(int id, string status)
    {
        LiveAdapollingProjectProcessStatus processstatus = new LiveAdapollingProjectProcessStatus
        {
            AdapollingProjectProcessStatusId = id,
            AdapollingProjectProcessStatus = status
        };

        //save it in database
        var result = _context.LiveAdapollingProjectProcessStatuses.Update(processstatus);
        _context.SaveChanges();
        return Json(processstatus);
    }

It is saving the data to the database now. Thanks for the help
