小编Ale*_*eks的帖子

我正在使用Entity Framework作为我的ORM连接两个SQL函数.当查询执行时,我收到以下错误消息:

The query attempted to call 'Outer Apply' over a nested query,
but 'OuterApply' did not have the appropriate keys

这是我的查询:

var ingredientAllergenData = (from ings in db.fnListIngredientsFromItem(productId, (short)itemType, productId)
                             join ingAllergens in db.fnListAllergensFromItems(productId.ToString(CultureInfo.InvariantCulture), (short)itemType, currentLang)
                             on ings.id equals ingAllergens.ingredientId into ingAllergensData
                             from allergens in ingAllergensData.DefaultIfEmpty()
                             where ings.table == "tblIng" || ings.table == ""
                             select new {ings, allergens}).ToList();

我在LINQPad中写了相同的查询,我得到了结果,所以我不确定是什么问题:

var ingredientAllergenData = (from ings in fnListIngredientsFromItem(1232, 0, 1232)
                             join ingAllergens in fnListAllergensFromItems("1232", 0, 1)
                             on ings.Id equals ingAllergens.IngredientId into …

我无法绑定包含对象列表的模型.当我尝试将数据从控制器传递到视图时没有问题,但是当我想要发回数据时,我得到一条消息,表明该方法不存在.

我正在使用ajax调用,并且作为数据我放了$ form.serialize()并且可以看到包含fiddler中所有数据的列表,但是我对绑定没有运气.

该模型是:

public class Single
{
   public int Id {get;set;}
   public string Name {get;set;}
   public List<SimpleDropdown> dddl {get;set;}
   public int SelectedEmp {get;set;}
}
public class MainModel
{
   public List<Single> main_model_list {get;set;}
}

在我的控制器中,现在的方法是:

[HttpPost]
public string SaveModel(MainModel model)
{
   return "";
}

此方法不会被调用,但是当我删除调用的参数时.所以我确定绑定不起作用.我有一个更复杂的模型,但我尽可能简化它,仍然无法让它工作.

所以我的问题是如何测试这个以查看问题是什么？

编辑:

我目前没有代码,但该代码功能正常,因为我在项目的其他地方使用它.它是这样的:

$("#form").submit(function( ) {
      $.ajax({
        url: "/Controller/SaveModel",
        type: "POST",
        data: $(this).serialize()
    });
});

表单看起来像这样:

@using (Html.BeginForm("SaveModel", "Home", FormMethod.Post, new { id = "form" })) 
{
    @for (var z = 0; z < ViewBag.groupes.Length; …

如上所述,这种情况发生在Safari中,而在Chrome和Firefox中它运行良好.

我认为这是因为变成json的对象有两个包含moment对象的属性.我将它们更改为日期对象并stringify传递了函数.

奇怪的是,如果我尝试这样做JSON.stringify(moment())是有效的,所以我不知道如何调试它并找到问题所在.

以下是Safari中错误的屏幕截图:

编辑:

经过一些调试后,我发现dhtmlxwindow onclose事件发生后会发生此错误.我在一个dhtmlx窗口中加载一个局部视图,在那里我创建了这个对象,在关闭窗口之前,该对象被推入一个初始化为父视图的列表中.

在我关闭窗口之前我做了,JSON.stringify(parent.addedContracts)并且在onclose事件发生后它工作正常(我没有覆盖代码)列表具有相同的对象(我检查了所有属性)但是stringify同一列表失败.

编辑:

创建添加到列表中的对象如下:

var contractStartDate = moment(contractStartDateCalendar.getDate(true), "L");
var contractEndDate = moment(contractEndDateCalendar.getDate(true), "L");

var newContract = {
    Id                  : uniqueId,
    FunctionDesc        : $("#contractFunction").val(),
    ContractHours       : $("#contractHours").val(),
    AdditionalCostFactor: $("#contractAdditionalCostFactor").val().replace(',', '.'),
    VacationFormula     : contractHolidayCostFactor,
    StartDate           : contractStartDate,
    EndDate             : contractEndDate,
    Notes               : Encoder.htmlEncode(tinyMCE.get('contractNotes').getContent()),
    DaysOfWeek          : workingDaysString,
    PlusMinus           : $("#contractTypeDropdown option:selected").data("plusminus"),
    SalaryCalculation   : $("#contractTypeDropdown option:selected").data("salarycalculation"),
    ContractTypeId      : $("#contractTypeDropdown").val(),
    ContractTypeName    : $("#contractTypeDropdown option:selected").text(), …

我的问题是在exec中使用表变量.

declare @sort_col nvarchar(1000) = 'itm_id'
declare @sort_dir nvarchar(4) = 'desc'
declare @filters nvarchar(1000) = ' and itm_name like ''%aa%'''

declare @temp table
(
 itm_id int
)

insert into @temp
EXEC('select itm_id from Tblitm where itm_name not like ''%aa%''')

EXEC('select * from (select (ROW_NUMBER() OVER (ORDER BY '+@sort_col+' '+@sort_dir+')) row_num, * FROM (select itm_id, itm_name, 
dbo.fnItmsHistory(itm_id) itm_history
         from dbo.Tblitm as itm
         left outer join '+@temp+' as temp on itm.itm_id = temp.itm_id
         where itm_id=itm_id and temp.itm_id = null '+@filters+') as x) …

我有多个员工的每日数据,并且根据可能意味着大量数据的开始时间和结束时间.

因此,使用映射插件,我将它们映射到一个大的列表,但我需要将它们按员工分组到较小的列表中,这样我就可以为每个员工制作一个表(如较小的视图模型),该表对该数据子集进行过滤和排序.

这是我用静态数据创建的基本示例.

$(function () {
    var data = {
        Employees: [{
            Id: 1,
            Name: "Employee1",
            Day: new Date(),
            Price: 12.54
        }, {
            Id: 2,
            Name: "Employee2",
            Day: new Date(),
            Price: 112.54
        }, {
            Id: 1,
            Name: "Employee1",
            Day: new Date(),
            Price: 12.54
        }, {
            Id: 3,
            Name: "Employee3",
            Day: new Date(),
            Price: 12.54
        }]
    };

    // simulate the model to json conversion. from now on i work with the json
    var jsonModel = JSON.stringify(data);

    function employeeModel(data) {
        var employeeMapping …

我从外部webapi获取带有json对象的字符串.我有一个代码将对象放入ExpandoObject列表,但必须有另一个解决方案,而不使用动态对象.

这是代码:

System.Net.HttpWebRequest request = 

(System.Net.HttpWebRequest)System.Net.WebRequest.Create("https://example.com/api/users.json");
request.Credentials = System.Net.CredentialCache.DefaultCredentials;
request.Headers["Authorization"] = "API key="+somekey;
// Ignore Certificate validation failures (aka untrusted certificate + certificate chains)
System.Net.ServicePointManager.ServerCertificateValidationCallback = ((sender, certificate, chain, sslPolicyErrors) => true);

System.Net.HttpWebResponse response = (System.Net.HttpWebResponse)request.GetResponse();
Stream resStream = response.GetResponseStream();
StreamReader reader = new StreamReader(resStream);
//response from the api
string responseFromServer = reader.ReadToEnd();
//serialize the data
var jss = new System.Web.Script.Serialization.JavaScriptSerializer();
System.Collections.IList users = (System.Collections.IList)((IDictionary<string, object>)((IDictionary<string, object>)jss.DeserializeObject(responseFromServer))["data"])["users"];

List<System.Dynamic.ExpandoObject> api_users = new List<System.Dynamic.ExpandoObject>();
//putting the expandable objects in list
foreach (var …

我需要在特定单元格中缩进文本.特定单元格是包含子项的xml元素.

我的XML是:
