Question

我的域模型是具有一个或多个CompanyAdmin实体的公司实体。

我意识到，对于在发布表单值时默认的模型绑定器，CompanyAdmin实体必须具有唯一的名称。

首次浏览该页面时，公司或CompanyAdmin都没有数据。这意味着，此代码在视图中不起作用，因此不显示输入文本框。

@Html.EditorFor(model => model.Company.CompanyContacts)

因此，要使它们显示我使用：

@Html.EditorFor(model => model.Company.CompanyContacts.ElementAt(0).FirstName)

但是，现在问题是在POST时模型绑定不起作用。我能找到的所有例子都使用已经创建的数据。

我怎样才能让它发挥作用？

视图模型

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace ContractorDirect.Models
{
  public class CompanyAdminViewModel
  {
    public Company Company { get; set; }
    public RegisterModel UserReg { get; set; }
  }
}

控制器

public ViewResult CompanyAdmin(int? id)
    {
        CompanyAdminViewModel cavm = new CompanyAdminViewModel();

        jobTitleRepository = new JobTitleRepository();
        companyContactRepository = new CompanyContactRepository();

        var jobtitles = jobTitleRepository.All;
        ViewBag.JobTitleId = new SelectList(jobtitles, "JobTitleId", "JobName");

        if (id.HasValue)
        {
            cavm.Company = companyRepository.Find((int)id);
            cavm.Company.CompanyContacts = companyContactRepository.All.Where(admin=>admin.IsCompanyAdmin).ToList();
            return View(cavm);
        }

        cavm.Company = new Company();
        cavm.Company.CompanyContacts = new List<CompanyContact>();
        cavm.UserReg = new RegisterModel();
        return View(cavm);
    }

    [HttpPost]
    public ActionResult CompanyAdmin(CompanyAdminViewModel cavm)
    {
        JobTitleRepository rep = new JobTitleRepository();
        var jobtitles = rep.All;
        ViewBag.JobTitleId = new SelectList(jobtitles, "JobTitleId", "JobName");

        cavm.UserReg.UserName = cavm.Company.CompanyContacts.ElementAt(0).Email;

        if (ModelState.IsValid)
        {
            AccountController account = new AccountController();
            account.Register(cavm.UserReg, "CompanyAdmin");
            companyRepository.InsertOrUpdate(cavm.Company);
            companyRepository.Save();
            return RedirectToAction("CompanyRegistrationConfirmation");
        }
        else
        {
            return View();
        }
    }

  @{
       ViewBag.Title = "CompanyAdmin";
   }

Answer 1

好的 - 问题出在视图中

这有效

@Html.EditorFor(model => model.Company.CompanyContacts[0].FirstName)

这不是

@Html.EditorFor(model => model.Company.CompanyContacts.ElementAt(0).FirstName)

使用新的子实体发布新实体
