Data from Controller to View

Topics: Writing modules
Sep 14, 2012 at 11:54 PM

Forgive me for being such a noob with orchard.  I have used the "building a hello world module" tutorial and everything works fine.  I think I may just need to somehow refresh the module but anyways...

I am trying to pass data from the controller to the view.  I can't get anything to work. (TempData, ViewData, Model)  I have even deleted the controller and the view still works which tells me it needs to be refreshed or it isn't even using the controller within Modules folder I created.

Thanks for any guidance...

Don't worry about being a n00b ;) The easiest way to get data into your view is through a shape. Here's what I recommend...

Create a Shape property on your controller:

        dynamic Shape { get; set; }

Then, inject a shape factory from the constructor:

        public SomeController(IShapeFactory shapeFactory) {
            Shape = shapeFactory;

Create a shape from your action and return an action result that sends that shape in:

        public ActionResult SomeAction(int someParameter) {
            var shape = Shape.SomeShapeName(
                SomeInteger: someParameter,
                SomeString: "Hello World"

            return View((object)shape);

Finally, create a template in your views folder:

The message is: @Model.SomeString and the number you asked for is: @Model.SomeInteger

Thank you.  I must be missing something.  In my view, @Model.SomeString does not seem be set.  It is just an empty string.  Do you have any idea what I could be missing?

A typo maybe? It's case-sensitive.

No. I have copied your code just to test and see some results.  And I only changed the Controller constructor name and the Action name.


One point to make that I do not understand.  If I comment out the controller then it still runs.  If no view is returned then it shouldn't work.  It's not cached.  I have checked that as well.  That shouldn't happen so I think the problem is somewhere else. 


I'm just going to try and create a new module.

Oh, I may have an idea. Try to return a ShapeResult instead.

Yeah, I already tried that after doing some research.  I'll attempt the new module and see where that gets me.  Thanks for the help.

Please keep us updated.

I think my problem may have been permissions because when I created the new Module I had to change the permissions to generate it.

Okay, I am getting somewhere now.  I have an error "Shape type SomeShapeName not found".  Where is it looking for SomeShapeName?  The code you gave me is using it in the Action but I have no clue how that works or where it is looking for SomeShapeName.  Thanks.

What it's telling you is that you need to create the template for that shape. That was the last step I gave you: in your Views folder, create a file named SomeShapeName.cshtml and paste in there the last bit of code I gave.

Cool.  I didn't understand that or read it well I guess.  Thanks for all your help.
