An alternate method that we could use is 1 frequently referred to as the "ViewModel" sample. When using this sample we generate strongly-typed classes which have been optimized for our precise view situations, and which expose Qualities with the dynamic values/content desired by our view templates.
As an example we have a DB with two tables identified as Pupil and Study course with two models Just about every. Around the client side We have now two views to render Every table.
Also publishing the same JSON again on the controller will rebuild the thing for you provided that you outline the right model. Perhaps during MVC2 it had been a major disadvantage.. but nowadays its a breeze and very easy. You ought to update your solution to replicate this.
By the way, NHibernate projections prove useful if a particular viewmodel needs a subset of the information from a persisted object.
By way of example, we might desire to change the "State" discipline inside our Edit and Generate views from becoming an HTML textbox to a dropdownlist. In lieu of challenging-code the dropdown list of country and location names inside the view template, we'd need to crank out it from a list of supported nations around the world and regions that we populate dynamically.

It may be seen as a specialized aspect of what will be a Controller (in the MVC pattern) that functions as a knowledge binder/converter that changes Model info into View facts and passes instructions within the View into your Model.
URL within just our browser we'll see that our edit UI is up-to-date to Screen a dropdownlist of countries and areas instead of a textbox:

A view model is comparable to the presentation model in that is a backing course for rendering a view. On the other hand, it's very unique from the Presentation Model or even a DTO in how it is created.
Using this view model in asp.net mvc view model in the view is straight-forward, just send a different instance of LoginModel to your view:
I then develop a listing item of style ProjectViewModel to hold the information from both equally the Challenge and Employee entities.
The one who design ViewModels, Views and Controllers do not have to worry about the company layer or even the DTO implementation mainly because he will make the mapping once the Some others developpers complete their implementation...
