获取数据到使用MVC的局部视图或布局 [英] Getting data into a partial view or layout using MVC

问题描述

我要显示的信息登录在布局和/或部分景色用户（用户名，公司名称，通知的数量等）。这些都将是共同的每一页上。有没有得到这个数据给他们的伎俩，或者是延长每个模型在他们这些信息的情况？

I want to display information about the logged in user (username, company name, number of notifications, etc) in the layout and/or partial views. These will be common on every page. Is there a trick for getting this data to them, or is it a case of extending each model to have this information in them?

推荐答案

我建议你可以去为孩子的行动，并从布局调用它，通过这种方式就可以避免开展的所有视图模型的信息。

I would suggest you can go for a child action and invoke it from the layout, By this way you can avoid carry out the information in all the view models.

例

儿童行动

public class UserController
{
  [ChildActionOnly]
  public PartialViewResult UserInfo()
  {
     var userInfo = .. get the user information from session or db

     return PartialView(userInfo);
  }
}

管窥

@model UserInfoModel

@Html.DisplayFor(m => m.UserName)
@Html.DisplayFor(m => m.CompanyName)
...

布局视图

<header>
  @Html.Action("UserInfo", "User")
</header>
