InvalidOperationException：未找到视图“AddValue”。提交表单数据时未找到部分视图

Question

我正在尝试从单个视图页面将数据插入到两个表中。我使用了两种不同的视图模型来做到这一点。所以我必须制作一个部分视图来在第二个表中插入数据。现在完整页面已打开，第一部分工作成功。虽然部分视图已打开，但当我提交数据时，它显示此错误：

InvalidOperationException：未找到视图“AddValue”。搜索了以下位置：
/视图/属性/AddValue.cshtml
/Views/Shared/AddValue.cshtml
/Pages/Shared/AddValue.cshtml

这是控制器代码：

public class AttributeController : Controller
{
    private readonly AttributeInfoService _attributeService;
    private readonly AttributeValueService _valueService;
    public AttributeController(IAttributeInfoRepository attributeRepository, IAttributeValueRepository valueRepository)
    {
        this._attributeService= new AttributeInfoService(attributeRepository);
        this._valueService= new AttributeValueService(valueRepository);
    }

    [HttpGet]
    public IActionResult ViewAttribute()
    {
        return View(_attributeService.GetAttributeList());
    }

    [HttpGet]
    public IActionResult AddAttribute()
    {
        ViewBag.attribute = _attributeService.AttributeDropDown();
        return View();
    }

    [HttpPost]
    public IActionResult AddAttribute(AttributeInfoViewModel avm)
    {
        if(ModelState.IsValid)
        {
            string status = _attributeService.Add(avm);
            if (status == "OK")
            {
                return RedirectToAction("AddAttribute");
            }
            
        }
        else {
            string msg = "fail";
            ViewBag.Message = msg;
        }
        
        return View(avm);
    }

    [HttpGet]
    public IActionResult EditAttribute()
    {
        return View();
    }

    [HttpPost]
    public IActionResult EditAttribute(AttributeInfoViewModel avm)
    {
        if (ModelState.IsValid)
        {
            var status= _attributeService.Update(avm);
            if(status == "OK")
            {
                return RedirectToAction("");
            }
        }
        return View(avm);
    }

    [HttpPost]
    public IActionResult DeleteAttribute(int id)
    {
        if (id != 0)
        {
            _attributeService.Delete(id);
            return RedirectToAction("");
        }
        return View();
    }


    [HttpGet]
    public IActionResult ViewValue()
    {
        return View(_valueService.GetAllAttributeValueList());
    }
    
    [HttpPost]
    public IActionResult AddValue(AttributeValueViewModel avm)
    {
        if (ModelState.IsValid)
        {
            string status = _valueService.Add(avm);
            if (status == "OK")
            {
                return RedirectToAction("AddValue");
            }
        }
        return View(avm);
    }

    [HttpGet]
    public IActionResult EditValue()
    {
        return View();
    }

    [HttpPost]
    public IActionResult EditValue(AttributeValueViewModel vm)
    {
        if (ModelState.IsValid)
        {
            string status = _valueService.Update(vm);
            if( status == "OK")
            {
                return RedirectToAction("");
            }
        }
        return View(vm);
    }

    [HttpPost]
    public IActionResult DeleteValue(int id)
    {
        if(id!=0)
        {
            _valueService.Delete(id);
            return RedirectToAction("");
        }
        return View();
    }
}

这里是查看代码：

@model DL.ViewModels.Configuration.AttributeInfoViewModel
@{
    ViewData["Title"] = "AddAttribute";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

<div class="d-flex justify-content-between mb-4">
    <div class="">

@await Html.PartialAsync("_AddValue")
@* <partial name="_AddValue.cshtml"/> *@


@section Scripts {
    <script>
        $("#left_Configuration_menu").show();
    </script>
}

这是部分视图代码：

@model DL.ViewModels.Configuration.AttributeValueViewModel

Answer 1

您的 PartialView 需要

AttributeValueViewModel

。您需要将其传递给

PartialAsync

方法。

@await Html.PartialAsync("_AddValue", new AttributeValueViewModel())

类似上面的东西。显然，您不会在这里创建新对象，而是必须在 Controller 中创建。
