    Strongly typing in v8 Custom Controller

    Hi,

    Following the official documentation at https://our.umbraco.com/documentation/reference/routing/custom-controllers I am attempting to build a custom controller which returns a custom view model.

    Here is my view model

    public class HomePageViewModel : ContentModel
    {
        public HomePageViewModel(IPublishedContent content) : base(content)
        {
        }  
    
        public string Heading { get; set; }
    }
    

    and here is my controller

            public override ActionResult Index(ContentModel model)
        {
            var vm = new HomePageViewModel(model.Content)
            {
                Heading = model.Content.Value<string>("heading")
            };
    
            return CurrentTemplate(vm);
        }
    

    This works as expected but i was wondering whether it is possible to make the contentModel into the type of the model generated by models builder so instead of using model.Content.Value

    I know in v7 when looping through children you could cast to the model type but i was wondering if its possible in the scenario ? I attempted to implement by casting using the bottom suggestion in this post https://stackoverflow.com/questions/34324608/umbraco-cast-ipublishedcontent-type-to-custommodel-type

    I have a core project and .web project. I have used the models builder tool to generate the models into my .core project which is where my controller resides.

    Is the model.Content.Value

    TIA

    Hi Paul,

    Yes it is possible.

    public override ActionResult Index(ContentModel model)
    {
        //This should do the job :-)
        var typedModel = model.Content as Umbraco.Web.PublishedModels.Home;
    
        var vm = new HomePageViewModel(model.Content)
        {
            Heading = model.Content.Value<string>("heading")
        };
    
        return CurrentTemplate(vm);
    }
    

    Thanks

    Nik

    Good morning Nik,

    Thanks for the reply! I was using the same code as you provided last night but was using model instead of .content :|. Tired mind!

    Do you know whether this strongly typed approach is standard practice i.e. would you expect developers to cast this or would you expect to see model.Content.Value

    I prefer the strongly typed approach but i also want to be following best practices.

    Thanks Paul
