Datatables is duplicating my columns

Hi Allan,

I hope you are doing well. I hope you can help me. I am having a weird behaviour on a particular Datatable. I am using datatables in my whole project but one in particular is returning double information, and the second one is empty and some values on my view are looking on that second information.

In the images attached you can see double row for the information requested in positions 1 and 3. position 1 is full with information 3 is completely empty.

Previously position 1 contains all the values except for the ID, for that reason I have to add the Id value in my controller in line 9, but this was already solve adding this line, when in other tables it was not necessary.

Additionally I am having another weird behaviour in my view, but I think this double row is the cause.

Controller

public ActionResult DTEvaluation()
        {
            var request = HttpContext.Request.Form;

            using (var dtDB = new DataTables.Database("sqlserver", conn))
            {
                var response = new Editor(dtDB, "Evaluation", "Id") //Application.
                    .Model<VMEvaluation>()
                    .Field(new Field("Evaluation.Id"))
                    .Field(new Field("Evaluation.OrganizationId"))
                    .Field(new Field("Evaluation.CreationDate")
                        .GetFormatter(Format.DateSqlToFormat("dd/MM/yyyy"))
                        .SetFormatter(Format.DateFormatToSql("dd/MM/yyyy"))
                    )
                    .Field(new Field("Evaluation.EvaluationDate")
                        .GetFormatter(Format.DateSqlToFormat("dd/MM/yyyy"))
                        .SetFormatter(Format.DateFormatToSql("dd/MM/yyyy"))
                    )

                    .Field(new Field("Evaluation.CycleId"))
                    .Field(new Field("Evaluation.AdHoc"))
                    .Field(new Field("Evaluation.IsClosed"))
                    .Field(new Field("Evaluation.DepartmentName"))
                    .Field(new Field("Evaluation.PositionName"))
                    .Field(new Field("Evaluation.ManagerName"))
                    .Field(new Field("Evaluation.Active"))
                    .Field(new Field("Cycle.YearCycle"))
                    .Field(new Field("Cycle.MonthCycleId"))
                    .LeftJoin("Cycle", "Cycle.Id", "=", "Evaluation.CycleId")                    
                    .Process(request)
                    .Data();

                return Json(response, JsonRequestBehavior.AllowGet);
            }
        }

Thank you so much in advance if you can give me a hand to understand why this behaviour of returning double information structure.

    Hi Allan,

    I forgot to atached the images to the previous comment.

    I just execute a Trace in the database to see what was the controller sending to the DB and I found all the fields are twice, the quantity of rows are OK , but I don't understand why the fields are twice.

    SELECT  Evaluation.Id as 'Evaluation.Id', Evaluation.Id as 'Evaluation.Id', Evaluation.OrganizationId as 'Evaluation.OrganizationId', 
            Evaluation.CreationDate as 'Evaluation.CreationDate', Evaluation.EvaluationDate as 'Evaluation.EvaluationDate', 
            Evaluation.CycleId as 'Evaluation.CycleId', Evaluation.AdHoc as 'Evaluation.AdHoc', Evaluation.IsClosed as 'Evaluation.IsClosed', 
            Evaluation.DepartmentName as 'Evaluation.DepartmentName', Evaluation.PositionName as 'Evaluation.PositionName', 
            Evaluation.ManagerName as 'Evaluation.ManagerName', Evaluation.Active as 'Evaluation.Active', 
            Cycle.YearCycle as 'Cycle.YearCycle', Cycle.MonthCycleId as 'Cycle.MonthCycleId', 
            EValuation.Id as 'EValuation.Id', EValuation.OrganizationId as 'EValuation.OrganizationId', 
            EValuation.CreationDate as 'EValuation.CreationDate', EValuation.EvaluationDate as 'EValuation.EvaluationDate', 
            EValuation.CycleId as 'EValuation.CycleId', EValuation.AdHoc as 'EValuation.AdHoc', EValuation.IsClosed as 'EValuation.IsClosed', 
            EValuation.DepartmentName as 'EValuation.DepartmentName', EValuation.PositionName as 'EValuation.PositionName', 
            EValuation.ManagerName as 'EValuation.ManagerName', EValuation.Active as 'EValuation.Active' 
    FROM  Evaluation 
            LEFT JOIN Cycle ON Cycle.Id = Evaluation.CycleId 
    

    Thanks,

    Hi Adam,

    Sorry, I am trying to find as much Information as I can to provide it to you. I change everything just to display two fields and even though both got duplicated. I don't get why.

    Controller

    [AcceptVerbs(HttpVerbs.Get | HttpVerbs.Post)]
            public ActionResult DTEvaluation()
            {
                var request = HttpContext.Request.Form;
    
                using (var dtDB = new DataTables.Database("sqlserver", conn))
                {
                    var response = new Editor(dtDB, "Evaluation", "Id") //Application.
                        .Model<VMEvaluation>()
                        .Field(new Field("Evaluation.Id"))
                        .Field(new Field("Evaluation.OrganizationId"))                             
                        .Process(request)
                        .Data();
    
                    return Json(response, JsonRequestBehavior.AllowGet);
                }
            }
    
    

    View Model

    In your model you have:

    EValuation

    In your controller you use:

    Evaluation

    Since C# is case sensitive, that's going to cause the issue you are seeing. Fix the typo in the model and it should hopefully work.

    Hi Allan,

    That solved my problem. Thank you so much I can't believe such an error, the additional problem was based on that as well.

    Thanks,

    Wilson
