blog post picker - multinode tree picker - mvc

Using Umbraco And Getting Started

Umbraco 7

so i am having quite a bit of difficulty to use the multinode tree picker in umbraco 7.6.4

i am using mvc, and have controllers, models and view divided.

I have setup my picker, and i can select blog posts in my page in backend. But how do i get the data for the picked blog posts ? so far i can only get the properties which umbraco sets, and the name of the blog post. But how do i get the data from the actual post ?

i am using viewbag and the data needs to get pulled in a partial view.

My Controller ( specificly TopMonthPicks, TopYearPicks )

public class MasterController : RenderMvcController
    {
        // GET: Master
        protected override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            // set frontpage.
            var frontPage = CurrentPage.AncestorsOrSelf().FirstOrDefault(x => x.Level == 1);

            ViewBag.Global = new Global()
            {
                MainMenu = GetMainMenu(frontPage),
                Title = frontPage.GetPropertyValue<string>("pageTitle"),
                SubTitle = frontPage.GetPropertyValue<string>("subPageTitle"),
                CurrentPage = CurrentPage,
                TopMonthPicks = frontPage.GetPropertyValue<IEnumerable<IPublishedContent>>("monthlyTopPicks"),
                TopYearPicks = frontPage.GetPropertyValue<IEnumerable<IPublishedContent>>("yearlyTopPicks"),

            };
        }

Hi Andre

First of all, are you planning do not use Umbraco in future?

Why did you decide to put all Umbraco data of the current page to the custom model class? You have this data in your razor code, don't need to pass it through controller one more time.

You can get all properties of blog posts:
```
var blogPosts = frontPage.GetPropertyValue<IEnumerable<IPublishedContent>>("monthlyTopPicks");
```
Thanks,

Alex

Andre, you can render all blog posts names with this code:

    @{
        var frontPage = Umbraco.AssignedContentItem.AncestorsOrSelf().FirstOrDefault(x => x.Level == 1);
    }

    @foreach (var post in frontPage.GetPropertyValue<IEnumerable<IPublishedContent>>("yearlyTopPicks"))
    {
        @post.Name
    }

i have this as an example.

@foreach (var item in global.TopMonthPicks)
        {
        <!-- Mini Post -->
            <article class="mini-post">
                <header>
                    <h3><a href="@item.Url">@item.Name</a></h3>
                    <time class="published" datetime="@item.CreateDate.ToString("MMMM dd, yyyy")">@item.CreateDate.ToString("MMMM dd, yyyy")</time>
                    <a href="#" class="author"><img src="Media/Static/avatar.jpg" alt="" /></a>
                </header>
                <a href="@item.Url" class="image"><img src="Media/Static/pic04.jpg" alt="" /></a>
            </article>
        }

I can get the url for the blog post, the name and creation date. But how do i for example get the image which i have added on the post ? i have a property called "image" (single image) on the document type blogItem, which i want to get.

How do i access this ?

Andre, you need something like that:

        <!-- Mini Post -->
        <article class="mini-post">
            <header>
                <h3><a href="@item.Url">@item.Name</a></h3>
                <time class="published" datetime="@item.CreateDate.ToString("MMMM dd, yyyy")">@item.CreateDate.ToString("MMMM dd, yyyy")</time>
                <a href="#" class="author"><img src="Media/Static/avatar.jpg" alt="" /></a>

            </header>
            @if (item.HasValue("image"))
            {
                var mediaItem = item.GetPropertyValue<IPublishedContent>("image");

                <a href="@item.Url" class="image"><img src="@mediaItem.Url" alt="" /></a>
            }
        </article>

Errors because your model properties are dynamics, can you use this code:

    @{
        var frontPage = Umbraco.AssignedContentItem.AncestorsOrSelf().FirstOrDefault(x => x.Level == 1);
    }


    @foreach (var item in frontPage.GetPropertyValue<IEnumerable<IPublishedContent>>("yearlyTopPicks"))
    {
        <!-- Mini Post -->
        <article class="mini-post">
            <header>
                <h3><a href="@item.Url">@item.Name</a></h3>
                <time class="published" datetime="@item.CreateDate.ToString("MMMM dd, yyyy")">@item.CreateDate.ToString("MMMM dd, yyyy")</time>
                <a href="#" class="author"><img src="Media/Static/avatar.jpg" alt="" /></a>

            </header>
            @if (item.HasValue("image"))
            {
                var mediaItem = item.GetPropertyValue<IPublishedContent>("image");

                <a href="@item.Url" class="image"><img src="@mediaItem.Url" alt="" /></a>
            }
        </article>
    }

if they are dynamic, then what can i do ?

it does not appear i can use it, since i am using my own view models.

it does not work, since it is a partial, should i add some sort of inherit at the top or ?
