在传递的对象上获取 ModelState.IsValid == false

Question

我收到一条错误消息“需要计算字段”

这是我的支出模型：

public class ExpendituresModel : PageModel
    {
        private readonly ISqlData _db;

        public ExpendituresModel(ISqlData db)
        {
            _db = db;
        }

        [BindProperty]
        public Project Project { get; set; }
        public List<Expenditure> Expenditures { get; set; } = null!;

        [BindProperty]
        public WipCommentCalculation WipCommentCalculation { get; set; }

      //  public Calculations Calculations { get; set; } = new Calculations();

        public int ProjectId { get; set; }
        

        public async Task OnGetAsync(int projectId)
        {
            Project = await _db.GetProjectDataAsync(projectId);

            //Expenditures = await _db.GetExpendituresByProjectIdAsync(projectId);

            var calculations = await _db.GetCalculationByProjectIdAsync(projectId);

            WipCommentCalculation = new WipCommentCalculation
            {
                Calculations = calculations,
                Comments = null,
                ProjectId = projectId
            };
        }

        public IActionResult OnPost()
        {
            if (ModelState.IsValid ==false)
            {
                return RedirectToPage("./Expenditures");
            }

            return RedirectToPage("./Expenditures");
        }
    }

这是它的视图：

@page
@using DataAccessLibrary.Models
@model WorkInProgress.Pages.ExpendituresModel
@{
    ViewData["Title"] = "Expenditures";
}

我不确定是否应该以不同的方式设置对象，

我进行了计算，但在调用 OnPost 时在对象中显示为 null

我想稍后将此对象与评论一起保存在数据库中，但来自表单的模型状态无效。

不知道怎么解释好。例如，我在我这边复制了您的代码并创建了一个模型 class，如下所示：

namespace WebApp.Model
{
    public class WipCommentCalculation
    {
        public int ProjectId { get; set; }
        public Calculations Calculations { get; set; }
    }

    public class Calculations {
        public decimal BillableLabor { get; set; }
        public decimal UnbilledLabor { get; set; }
        public decimal BillingHoldLabor { get; set; }
        public decimal UnbilledSubcontractor { get; set; }
        public decimal BillingHoldSubcontractor { get; set; }
        public decimal BillableNonLabor { get; set; }
        public decimal UnbilledNonLabor { get; set; }
        public decimal BillingHoldNonLabor { get; set; }
        public decimal BillableSubcontractor { get; set; }
    }

    public class Project {
        public string FiscalMonth { get; set; }
        public string PtdBilled { get; set; }
    }
}

然后当我把你的代码放在我的视图中时，我也会让它无效，但是如果我像这样使用表单dom，那么它就可以有效：

<form method="post">
   <div>
        <div>
            <label for="BillableLabor">BillableLabor:</label>
            <input type="text" asp-for="@Model.WipCommentCalculation.Calculations.BillableLabor" value=""  />
        </div>
        <div>
            <label for="UnbilledLabor">UnbilledLabor:</label>
            <input type="text" asp-for="@Model.WipCommentCalculation.Calculations.UnbilledLabor" value=""  />
        </div>
    </div>
    <div class="form-control">
        <input type="submit" value="Save" class="btn btn-primary"/>
    </div>
</form>

我想你使用了ModelState.IsValid那么你应该遵守提交规则。对元素使用标签助手 asp-for="@Model.WipCommentCalculation.Calculations.BillableLabor"。

在传递的对象上获取 ModelState.IsValid == false
