我在渲染局部问题时遇到了问题。我环顾四周,发现你应该将路径作为第一个参数传递给局部视图,如果你使用了一个参数,那么你的模型会传递到第二个参数,因为它是一个参数重载。我得到了这个页面,没有任何东西爆炸,但部分视图没有输出我的预期结果,我不能在那个部分(它使用循环)上找到一个断点。我已经确认我已经传递了一个包含数据的模型,但是部分似乎没有被击中。这是我的控制器和部分。
DataBass db = new DataBass();
public ActionResult Address()
{
Models.ViewModels.CheckoutViewModel x = new Models.ViewModels.CheckoutViewModel();
if (User.Identity.IsAuthenticated)
{
using(DataBass oDB = new DataBass())
{
var Customer = oDB.Customers.First(c => c.Email.ToLower() == User.Identity.Name.ToLower());
var AvailableAddresses = oDB.AddressBooks.Where(ab => ab.CustomerID == Customer.ID).ToList();
x.CustomerID = Customer.ID;
x.HasExistingAddresses = (AvailableAddresses.Count > 0 ? false : true);
x.AvailableAddresses = AvailableAddresses;
}
//var UserAddresses = db.AddressBooks.Where(a => a.Customer.Email == User.Identity.Name);
//ViewBag.Addresses = UserAddresses;
return View("Shipping", x);
}
else
return View("Index");
}
以下是我遇到麻烦的部分观点。这就是没有被击中的。
@model IEnumerable<Models.AddressBook>
<h2>AddressBook</h2>
<table class="table">
<tr>
<th>
Address 2
</th>
<th>
Address 1
</th>
<th>
City
</th>
<th>
State
</th>
<th>
Postal Code
</th>
<th></th>
</tr>
@foreach (var item in Model)
{
var states = (List<Models.State>)ViewBag.States;
<tr>
<td>
@Html.DisplayFor(modelItem => item.Address1)
</td>
<td>
@Html.DisplayFor(modelItem => item.Address2)
</td>
<td>
@Html.DisplayFor(modelItem => item.City)
</td>
<td>
@states.FirstOrDefault(x => x.ID.ToString() == item.StateID).Name
</td>
<td>
@Html.DisplayFor(modelItem => item.Zipcode)
</td>
<td>
@Html.ActionLink("Choose this one","", new { id = item.ID}, new { @class="button"})
@*@Html.ActionLink("Edit", "EditAddress", new { id = item.ID }, null) |
@Html.ActionLink("Delete", "DeleteAddress", new { id = item.ID }, null)
@*<a href="/Account/EditAddress/@item.AddressBook_ID">Edit</a> |
<a href="/Account/DeleteAddress/@item.AddressBook_ID">Delete</a>
@Html.ActionLink("Edit", "EditAddress", new { id = item.ID }, null) |
@Html.ActionLink("Edit", "EditAddress", "Account",new { id=item.AddressBook_ID }, htmlAttributes: null ) |
@Html.ActionLink("Delete", "DeleteAddress", new { id = item.ID }, null)*@
</td>
</tr>
}
</table>
以下是我的观点,即调用上面显示的ChooseExistingAddress.cshtml部分的renderpartial方法。
@model Models.ViewModels.CheckoutViewModel
@{
ViewBag.Title = "Shipping Selection";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<h2>Shipping</h2>
@if (Model.HasExistingAddresses)
{
Html.RenderPartial("~/Views/Checkout/ChooseExistingAddress.cshtml", Model.AvailableAddresses);
}
else
{
Html.RenderPartial("~/Views/Checkout/AddNewShippingAddress.cshtml");
}
答案 0 :(得分:3)
你的三元逻辑倒退了:
x.HasExistingAddresses = (AvailableAddresses.Count > 0 ? false : true);
换句话说,如果地址数大于0,则将其设置为false,而在这种情况下应该为真。无论如何,你真的不需要三元组。只需将其设置为布尔表达式的结果:
x.HasExistingAddresses = AvailableAddresses.Count > 0;
