copied!<p>example: Books and Authors entities when creating a new book in a view, you need a select control that has its options populated as all the available authors.</p> <p>the Book model should be clean and contain only the relevant fields e.g. Title, Author</p> <p>the controller should have an IAuthorRepository _authorRepository; field that could have been set by a DependencyResolver or manually in the controllers constructor. IAuthorRepository would have a method such as IEnumerable GetAvailableAuthors();</p> <p>the [HttpGet] Create() action could return an empty Book model directly and then stuff the _authorRepository into the dynamic ViewBag. ViewBag.AuthorRepository = _authorRepository;</p> <p>The view would then pass the ViewBag.AuthorRepository to a partial view or a custom editor. Your model is kept clean in this scenario.</p> <p>Some people don't like any use of ViewBag.Xxx (or ViewData["Xxx"]) because it's less than perfect MVC. I've seen examples that would Create a new type like BookViewModel. BookViewModel would then contain Book and IAuthorRepository in itself. the [HttpGet] Create() action would then return a BookViewModel object and the view would render its Author Select partial view by passing it the model.AuthorRepository instead of the ViewBag.AuthorRepository. This sort of starts to look more like MVVM here rather than MVC. Your instinct to keep any such collections or repositories out of the actual model (Book) is right. A clean model is very important and will give you the most flexibility in any pattern.</p>
