如何解决Umbraco 7-if字段
我对此很陌生，正在使用Umbraco v7中已经存在的网站。
我试图在属性别名freeProgram为true时显示Free一词。
FreeProgram已经在文档类型程序上设置了一个复选框
它被用来创建过滤器，并且在一些地方被引用
此内容是通过部分模板创建的-这是代码（如果freeProgram为true，则包括创建内容的许多尝试中的一部分）
@model PerformanceSpace.Models.VM_Cards
@{ var imgurl = String.Format("{0}?width={1}&height={2}&mode=crop",Model.imgUrl,Model.doubleCrop ? 700 : 400,Model.doubleCrop ? 400 : Model.smallCard ? 400 : 496); }
<div class="card-image">
@if (!String.IsNullOrEmpty(Model.imgUrl))
{
<img src="@imgurl" alt="@Model.imgAlt">}
</div>
@if (Model.smallCard)
{
<div class="py16 px16">
<h3 class="h6 mb0 card--title" style="color:@Model.txtColour !important">
@Model.title
</h3>
</div> }
else
{
<h3 class="h6 mb0 card__heading">
<span class="text--hl card--title" style="background-color:@Model.colour;">
@Model.title
</span>
</h3>}
<div class="card__date mt16" style="color:@Model.txtColour !important">
<small>@Model.subTitle</small>
</div>
</a>
@{
if (!Model.Value<bool>("freeProgram"))
{
<p>The Checkbox is not checked!</p>
}
}
当前，这可防止打开物品。追溯过去（记住我对此一无所知）
我尝试了许多不同的语法，并复制了控制器中用于获取相同内容的if语句
@if (model.freeProgram)
{
<div>free</div>
}
这是包含VMCards类的模型

因此，据我了解，这似乎不是通过创建文档类型创建的模型-没有称为VM的文档类型
freeProgam属性别名最初是在Property模型中设置的。这是属性模型头和相关代码。

我想我不理解用modelsbuilder创建的模型与如何在另一个名称空间中使用它们之间的关系（我什至不确定该名称空间是什么，但我猜想它会以某种方式将它们分开）
所以我想做的是在设置了该属性别名的项目中添加free这个词。我要去哪里错了？非常感谢。有人告诉我这是一个Wordpress网站，我的期限很紧，现在他们找不到其他人可以这样做，而且该网站在两天内上线了……呃……。
解决方法
如果该部分模板实际上已渲染并且正确填充了模型VM_Cards，那么您应该能够做到
@if(Model.freeProgram) {
<p>Really free</p>
}
尝试显示该属性的值时遇到任何错误吗？
此外，类VM_Cards具有一些不同的构造函数，并且freeProgram并未在所有构造函数中初始化。
您能显示传递给视图的模型是如何构建的吗？在代码中的某个位置可能有一个控制器（.cs文件），该控制器构造了传递给视图的模型？在代码库中搜索部分视图的名称（不带.cshtml），您应该能够找到将VM_Cards传递到视图的代码。
