如何确定使用ViewModels重定向到哪个视图？

Question

I am currently using ViewModels to bind to all my CRUD operations, but there are some action methods only returning partial views:

public ActionResult Create(int parentId)
{
    var viewModel = new MyCreateViewModel();
    return PartialView("_Create", viewModel);
}

These actions will be called from different views (different entities) via AJAX, and displayed in a jQuery dialog. The dialog buttons will handle the POST ing of the form via $("#form").submit() , and another action method will process the form, ideally redirecting to the parent view that called the partial view :

[HttpPost]
public ActionResult Create(int parentId, MyCreateViewModel viewModel)
{
    //Process the viewModel, map to EF models and persist to the database

    return RedirectToAction(/*What should I insert here?*/);
}

Since I do not know which view is POST ing to this method, how can I know which view should I redirect to?

Answer 1

I would add a string property to your viewModel that contains the name of the view you want to return

[HttpPost]
public ActionResult Create(int parentId, MyCreateViewModel viewModel)
{
    //Process the viewModel, map to EF models and persist to the database

    return RedirectToAction(viewModel.ViewToRender);
}

You can redirect in client side instead of doing that in the action method. In the action method, you can return a result indicating the operation is success or fail. In the client side, use $.ajax to handle the result

        $('#form').submit(function () {
        var self = $(this);
        if (self.valid()) {
            $.ajax({
                type: "POST",
                url: self.attr('action'),
                data: self.serialize(),
                success: function (data) {
                    if (data.Success == true) {
                        //redirect
                    } else{
                        //Error handling
                    }
                },
                error: function (ex) {
                        //Error handling
                }
            });
        }
        return false;
    });
