Your reasoning is questionable and suspect to favoritism. Granted I'm sure practically nothing about MVVM, however, if an architecture which include MVC can mimic the actions with-out being forced to produce 50k strains of code, then whats the massive offer?
While in the Strongly typed View, we Enable the View know the type of ViewModel getting handed to it. With all the strongly typed view, you're going to get Intellisense aid and compile time mistake checking.
Due to the fact we also render the Edit view template through the HTTP-Publish Edit system (in scenarios when glitches happen), we will want to be sure that we also update this method to include the SelectList to ViewData when the view template is rendered in error situations:
Now run the applying and navigate to your /Pupil/Details URL. As revealed while in the image down below, you will notice the expected output over the webpage.
Give some significant title. It really is prompt to suffix the identify of View manner to “ViewModel” term so that it's may be very easily distinguished in the Model folder between other Models.
I've also observed other programmers utilize the ViewData to deliver the dropdown lists into the view, but I dislike that due to the fact ViewData isn't strongly typed, While a ViewModel is.
A standard approach to creating a View Model would be to compose it from some area entities and perhaps a sprinkling of Houses. A View for introducing a different merchandise on the Northwind database will require fields for every one of the Merchandise Qualities along with a strategy for specifying which Class The brand new Merchandise object belongs to. This is something which will do the job:
(That features things like SelectLists. Neither your controller nor view should really should know how to make a SelectList for the dropdown.)
It may not be a dilemma now, but It will be fantastic follow so as to add the brackets now to avoid wasting on your own muchos effort in the future when it turns into a necessity, it's also very good OO exercise to encapsulate the features.
It seems from this that just one would wish to consider excess measures to develop up a person's Presentation Model from an EF Entity, e.
@Chef_Code: It's not at all questionable or favoritism: just read through the initial paper about MVC. Going back to the resource is significantly better than blindly pursuing the herd devoid of concern (aka "ideal procedures"). MVC is meant for much lesser models: e.g.
Due to this, a DTO formed to some view is basically the same as the ViewModel. On the other hand, in larger techniques with One more serialization boundary, a DTO may very well be advantageous if independent from a ViewModel exclusively shaped to view model in asp.net mvc the View.

My desire is to create View Models distinct for individual Views. Although this might entail more coding - plus some might say a duplication of properties across entities and View Models, AutoMapper helps to minimise the additional function concerned.
