在index.cshtml页面上是Create.cshtml吗？

Question

I have renderad a CRUD with .net and have the following files in the same folder.

Create.cshtml, Delete.cshtml, Details.cshtml, Edit.cshtml, Index.cshtml

Now it is a link to create a new record on the index page

@Html.ActionLink("Create New", "Create")

But I want the create form to be on the index page.

I tested to use PartialView (I do not know whether it is better to copy the code from create.cshtml in index.cshtml or to use two files but I get the same error).

Changed the return in the controller to return PartialView(board);

And the view to @Html.Partial("Create")

But I get the compiling error

The model item passed into the dictionary is of type 'System.Collections.Generic.List`1[Klotterplank.Models.Board]', but this dictionary requires a model item of type 'Klotterplank.Models.Board'.

This is the model I use in index.cshtml

@model IEnumerable<Klotterplank.Models.Board>

And this is the model I use in create.cshtml

@model Klotterplank.Models.Board

Answer 1

如果您在具有不同模型的父页面中使用PartialView，则必须将其他模型传递给Html Helper，如下所示：

@Html.Partial("Create", new Klotterplank.Models.Board())

Answer 2

The error tells pretty much itself: When a partial view is instantiated, it gets a copy of the parent view's ViewData dictionary . Your Create view needs data of different type, so you can provide it like this:

@Html.Partial("Create", viewModel)

viewModel can be equal to Model.Fist() (since on your Index view you have a collection of boards as model) for example.
