[英]Working with EF Generated Model and My Own Model
I have 2 Models. 我有2个模型。 First one is created by EF and looks like:
第一个由EF创建,如下所示:
public partial class PrinterMapping
{
public string MTPrinterID { get; set; }
public string NTPrinterID { get; set; }
public string Active { get; set; }
}
I created the second one (nothing to do with any database table) and looks like: 我创建了第二个数据库(与任何数据库表无关),如下所示:
public class ExceptionModel
{
public string ExceptionMessage { get; set; }
public ExceptionModel(string exceptionMessage)
{
ExceptionMessage = exceptionMessage;
}
}
In my Index and Create views, the model that is automatically being passed is PrinterMapping. 在“索引”和“创建”视图中,自动传递的模型是PrinterMapping。 I wish to output ExceptionMessage property of the ExceptionModel model after populating it in a relevant way after saving to the table accessed by PrinterMapping.
在保存到PrinterMapping访问的表后,我希望以相关方式填充ExceptionModel模型的ExceptionMessage属性。 So in my Create controller, I am doing:
因此,在我的Create控制器中,我正在执行以下操作:
ExceptionModel exModel = new ExceptionModel(message);
where message parameter is a relevant string like "Printer X already exists". 其中message参数是一个相关的字符串,例如“打印机X已经存在”。
My thoughts were to have a partial view called ExceptionMessageView where my ExceptionModel would be passed on to it and I will display: 我的想法是要有一个名为ExceptionMessageView的局部视图,将ExceptionModel传递给它,然后我将显示:
@Html.DisplayFor(model => model.ExceptionMessage)
And in my Index and Create views, I will have a line like: 在“索引”和“创建”视图中,我将显示以下行:
@Html.Partial("~/Views/Home/ExceptionMessageView.cshtml")
Am I over complicating things? 我是否使事情复杂化? This isn't working anyway since I don't fully understand how to pass on the populated ExceptionModel from my Create Controller to the ExceptionMessageView partial view.
无论如何这是行不通的,因为我不完全了解如何将填充的ExceptionModel从我的Create Controller传递到ExceptionMessageView局部视图。
Will a kind soul please enlighten? 请问一个善良的灵魂开悟吗?
I would have a complex Viewmodel "PrinterViewModel" that has properties for ExceptionModel and PrinterMapping. 我将拥有一个具有ExceptionModel和PrinterMapping属性的复杂ViewModel“ PrinterViewModel”。
The controller then passes the complete PrinterViewModel to the view. 然后,控制器将完整的PrinterViewModel传递给视图。
In the View you would render partials by passing part of the complex Viewmodel to them. 在视图中,您可以通过将部分复杂的Viewmodel传递给局部来渲染局部。
@Html.Partial("ExceptionMessageView",Model.Exception)
