传递两个模型查看 [英] pass two models to view

问题描述

我是 mvc 的新手，并尝试通过用它做一个小项目来学习它.我有一个页面应该显示该特定日期的货币和天气.所以我应该通过货币模型和天气模型.我已经完成了通过货币模型并且工作正常，但我不知道如何通过第二个模型.而且大部分教程都展示了如何只通过一个模型.

I am new to mvc and try to learn it by doing a small project with it. I have a page which is supposed to display that specific date's currencies and weather. so I should pass currencies model and weather model. I have done to pass currencies model and works fine but I dont know how to pass the second model. And most of the tutorials on the shows how to pass only one model.

你们能告诉我怎么做吗.

can you guys give an idea how to do it.

这是我当前发送货币模型的控制器操作

this is my current controller action which sends currency model

public ActionResult Index(int year,int month,int day)
    {
        var model = from r in _db.Currencies
                    where r.date == new DateTime(year,month,day)
                    select r;

        return View(model);
    }

推荐答案

您可以创建包含两个模型的特殊视图模型:

You can create special viewmodel that contains both models:

public class CurrencyAndWeatherViewModel
{
   public IEnumerable<Currency> Currencies{get;set;}
   public Weather CurrentWeather {get;set;}
}

并将其传递给查看.

public ActionResult Index(int year,int month,int day)
{
    var currencies = from r in _db.Currencies
                where r.date == new DateTime(year,month,day)
                select r;
    var weather = ...

    var model = new CurrencyAndWeatherViewModel {Currencies = currencies.ToArray(), CurrentWeather = weather};

    return View(model);
}
