我在视图中收到重复的行。我想要一个显示用户所有数据的视图（电子邮件，电话，地址）。当我点击具有两个不同地址，电话号码和电子邮件的用户时，我的列表中最终会有8个内容，因此我的viewmodel中有8个对象。
以下是我查询数据库的方法。
public ActionResult View_All(int? id)
{
var cape = from c in db.Constituent
join ca in db.ConstituentAddress on c.ConstituentId equals ca.ConstituentId
join cp in db.ConstituentPhone on c.ConstituentId equals cp.ConstituentId
join ce in db.ConstituentEmail on c.ConstituentId equals ce.ConstituentId
where ca.ConstituentId == id
&& c.ConstituentId == id
&& cp.ConstituentId == id
&& ce.ConstituentId == id
select new ConstituentDetailsView
{
zConstituent = c,
zConstituentAddress = ca,
zAddress = ca.Address,
zConstituentEmail = ce,
zEmail = ce.Email,
zConstituentPhone = cp,
zPhone = cp.Phone
};
return View("ConstituentDetails/View_All", cape);
}
查看：
@model IEnumerable<CodeFirstShenanigansWeb.Models.ConstituentDetailsView>
@{
ViewBag.Title = "View All";
}
<h2>Details</h2>
<h3>@Model.ElementAt(0).zConstituent.FirstName @Model.ElementAt(0).zConstituent.LastName</h3>
<h4>@Model.Count();</h4>
<h2><b>Addresses</b></h2>
@foreach (var item in Model)
{
<div>
<div>@item.zAddress.Street</div>
<div>@item.zAddress.City</div>
<div>@item.zAddress.State</div>
<div>@item.zAddress.Zip</div>
</div>
}
<h2><b>Phone Numbers</b></h2>
@foreach (var item in Model)
{
<div>
<div>@item.zPhone.Number</div>
</div>
}
<h2><b>Email Addresses</b></h2>
@foreach (var item in Model)
{
<div>
<div>@item.zEmail.Mail</div>
</div>
<p>
@Html.ActionLink("Edit", "EditAll", new { id = item.zConstituent.ConstituentId})|
@Ajax.ActionLink("Delete", "DELETE", new { id = item.zConstituent.ConstituentId }, new AjaxOptions
{
Confirm = "Are you sure you want to delete?",
OnComplete = "deleteComplete",
HttpMethod = "DELETE"
})
@Html.ActionLink("Back to List", "Index")|
</p>
}
视图模型：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using CRM.DomainClasses.Enums;
using CRM.DomainClasses;
namespace CodeFirstShenanigansWeb.Models
{
public class ConstituentDetailsView
{
public Constituent zConstituent { get; set; }
public Address zAddress { get; set; }
public Phone zPhone { get; set; }
public Email zEmail { get; set; }
public ConstituentPhone zConstituentPhone { get; set; }
public ConstituentEmail zConstituentEmail { get; set; }
public ConstituentAddress zConstituentAddress { get; set; }
}
}
我想我需要更多的ViewModel：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using CRM.DomainClasses;
namespace CodeFirstShenanigansWeb.Models
{
public class ConstituentListDetailsView
{
public Constituent zConstituent { get; set; }
public ICollection<Address> zAddress { get; set; }
public ICollection<Phone> zPhone { get; set; }
public ICollection<Email> zEmail { get; set; }
public ConstituentPhone zConstituentPhone { get; set; }
public ConstituentEmail zConstituentEmail { get; set; }
public ConstituentAddress zConstituentAddress { get; set; }
}
} 我感谢任何帮助。谢谢！
