模型视图控制器在Grails数据库后端？ [英] model view controller in grails with out database backend?

问题描述

我对MVC没有任何经验，并且正在尝试使用Grails编写一个简单的Web应用程序。我发现的所有例子都假设你有一个数据库来基于你的域类，并且有一个基于数据库的模型。我通过套接字通信的API获取数据，并希望模型基于该数据。是否有任何使用MVC应用程序的模型组件的数据源之外的源代码的例子？我更喜欢这些例子是在Grails中，但会起诉任何我可以得到的基于Web的例子。 解决方案

href =http://grails.org/Command+objects+and+Form+Validation =nofollow noreferrer>命令对象。它们与域对象非常相似，因为您可以对它们进行整齐的验证，但它们不会映射到任何数据库。

I don't have any experience with MVC, and am trying to use Grails to write a simple web app. All the examples I've found assume you have a database to base your domain classes off of, and there for have a model based on a database. I'm getting data through an API that does socket communication, and would want the model to be based on that Data. Are there any examples of using a source other then a database for the model component of an MVC app? I'd prefer the examples to be in Grails but will sue any web based examples I can get.

解决方案

Check out command objects. They're pretty much like domain objects as you can do neat things like validation on them, but they're not mapped to any database.
