media id conversion to url

Hey there!

Been having a hard time cracking this, after trying every possible link on this forum & google results, including the official docs. Maybe I'm missing something...

All information is retrieved properly except for media Url for the article box, I'm getting the ID, printed both in data-background upon inspection as well as in the badge. Badge turns red when mediaId cannot be read or is not defined (in the case of demo course 2 it is not defined).

Running u7.14.

Here's the view

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage<ContentModels.Courses>
@inherits Umbraco.Web.Mvc.UmbracoTemplatePage<ContentModels.Course>
@inherits Umbraco.Web.Mvc.UmbracoTemplatePage

  Layout = "MasterMembers.cshtml";
  var courseList = Model.Content.Children<Course>();
}

    @{
      foreach (Course c in courseList)
      {
        if (c.UlmsCourseVisibility.ToString() == "Published")
        {
            var courseHasImage = @c.UlmsCourseImage;

            <div class="col-12 col-md-4 col-lg-4">

It appears that your property c.UlmsCourseImage contains only the id of the media item. In this respect, it isn't a media object - but rather a plain int.

In order to get the media URL, you'll need to use something like Umbraco.TypedMedia to retrieve the actual media item using the id. From there, you'll be able to access additional properties such as .Name and .Url

Something like the following should hopefully work:

 <div class="article-image" data-background="@Umbraco.TypedMedia(c.UlmsCourseImage).Url"></div>

Hi Rhys!

Thanks for your quick reply. Tried this and results into a server error

Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

Am I lacking using or inherits statements?

It looks to me like you're getting a null exception, which might indicate that the c.UlmsCourseImage is empty.

When you implemented the following:

<div class="article-image" data-background="@Umbraco.TypedMedia(c.UlmsCourseImage).Url"></div>

Did you only apply this within the if statement?

Yes as it's the only property not being retrieved. I'm a total beginner so yeah, for sure some things are not very obvious to me :D

Changed the following:

<div class="article-image" data-background="@c.UlmsCourseImage">

to

<div class="article-image" data-background="@courseHasImage.Url">

and background url changred from "1296" to "background-image: url("/media/1004/mel-233281-unsplash.jpg");

yet still not a full path

&& updated media with freshly uploaded image, mediaId change to a corresponding one. So querying seems to be working fine.

Ah, that makes sense then - it looks like c.UlmsCourseImage is returning a media object afterall (my mistake!).

In which case, you won't need to turn it into a media object, so you can ignore the Umbraco.TypedMedia stuff.

Just to clarify then, does your image render properly now?

The .Url will give the relative path, so is there any particular reason why you need the absolute path?

So it seems that the solution indeed to try with a newly uploaded media file. Though it could retrieve the mediaId from the db, it didn't update for whatever reason.

The solution was to change c.UlmsCourseImage.Url to courseHasImage.Url plus var courseHasImage = c.UlmsCourseImage;

TIP

when in doubt freshen up your media files with new ones ;)
