c# – 自定义表面控制器Umbraco问题

2023年7月28日 261次阅读

首先,我想澄清一点,我只是在学习ASP MVC和Umbraco :).可能有非常新手的错误.

我正在努力建立一个采访系统.在互联网上搜索,我找到了一个改变口味的例子.

我创建了一个用于测试的空项目,这就是我所拥有的.

            foreach (var currentPoll in testPage.Where("Active"))
            {
                questions.Add(new PollViewModel { ID = currentPoll.ID, Title = currentPoll.Name.ToString(), Answers = AnswerList(currentPoll.ID) });
            }

            return PartialView("~/Views/Polls.cshtml", questions);
        }

        private List<Answer> AnswerList(int myQuestionID)
        {
            var questionPage = Umbraco.Content(myQuestionID);

最佳答案 从您的错误您获得与Polls名称空间和Umbraco.Web.PublishedContentModels.Polls名称空间的名称空间冲突.您可以更改名称空间以匹配Umbraco(不推荐),也可以尝试将名称空间更改为与Umbraco名称空间不冲突的唯一名称空间.

类似于：MyRootNamespace.Polls,您将使用自己的自定义命名空间替换MyRootNamespace.

SurfaceController

namespace MyRootNamespace.Polls.Controllers {
    public class PollsController : SurfaceController {...}
}

楷模

namespace MyRootNamespace.Polls.Models {
    public class Answer {...}

    public class PollViewModel {...}
}

PartialView“民意调查”

@model IEnumerable<MyRootNamespace.Polls.Models.PollViewModel>

<div>
    ...
</div>
