问题描述
难道在你的asp.net的MVC创建模型的最佳实践 - 模型文件夹。
使用这些模型与您的意见,并通过使用一个服务层,以适应我的模型的EF-模式。
Would it be best practice to create a model in your asp.net mvc - model folder.Use these models with your views and by using a service layer to "adapt" my model to the EF-model.
或者你使用另一种方法。这种技术途径的问题是,大多数时候我(自制)模型是EF-模型(未干)
Or have you used another approach. The problem with this approachs is that most of the times my (selfmade)model is a copy of the EF-model (not dry)
所以,有人可以解释我的原因是becomming很困惑你的看法使用什么型号。模型/视图模型/ Entityframeworkmodel ....
So can someone explain me what models to use with your view cause it is becomming very confusing. model / viewmodel / Entityframeworkmodel ....
解决方案:
感谢所有的答案猜猜我是此刻重构一些事情!
Thanks for answers all guess i am at the moment to refactor some things!
推荐答案
正确的做法是使用视图模型不同阶层和不同的持久性(实体)。通常的原因是,你往往需要一些额外的数据发送到一个视图(例如数据来填充下拉菜单,数据禁用某些字段等等),使用不同的验证或显示一个实体的唯一子集。
The correct approach is using different class for ViewModel and different for a persistance (entity). The usual reason is that you often need to send some additional data to a view (for example data to fill drop downs, data to disable some fields etc.), use different validation or show only subset of an entity.
我不纯粹。如果我看到我的视图模型是完全一样的实体,我直接用实体,但我会重构code一旦我需要在视图中的任何其他信息。大多数时候我开始与实体和我的观点,因为增量发展模式结束。
I'm not purist. If I see that my view model is exactly the same as the entity I use the entity directly but I will refactor the code once I need any additional information in the view. Most often I start with entities and I end with view models because of incremental development.
