I need to insert text for a media item when getting a media type of PDF by changing the GetMediaUrl method. This is for an RTE field. I went to override the MediaProvider, but found it was obsolete and replaced by the MediaManager. I created a class that inherits from the BaseMediaManager. Now I am wondering how to add that class to the pipeline. I see the one for MediaProvider, but can't figure out where to add one for MediaManager.

I found this for Media Provider:

<mediaProvider type="Sitecore.Resources.Media.MediaProvider, Sitecore.Kernel"/>

Thanks

  • Which Sitecore version is used? – Tamás Tárnok Jan 25 '18 at 17:21
  • Currently using 8.2 update 4. – RReilley Jan 25 '18 at 17:28
  • Looks like this is the issue. So would this be a duplicate question? I will flag for delete if so. sitecore.stackexchange.com/questions/7348/… – RReilley Jan 25 '18 at 18:28

    As you found out, mediaProvider is not a pipeline, it is a single type setting. MediaProvider has also (incorrectly?) been marked as [Obsolete] but no alternative has been provided to use, and Sitecore itself is using it as the default provider, so you'll have to ignore the warning, maybe disable it... – jammykam Jan 25 '18 at 18:45
  • @jammykam yep. Not sure after all I will need to change it or not yet. I am still looking through the methods, but I need to change the text of the link. The GetMediaUrl just returns the link. I may post another question if I can't find it. – RReilley Jan 25 '18 at 18:56

You need register the new Media Manager using Sitecore Dependency Injection (see 'Registration in code' chapter). It can be done via Service Configurator as described in the article.

Creating Service Configurator

Implement Sitecore.DependencyInjection.IServicesConfigurator interface from Kernel assembly. Please note that you need to reference Microsoft Dependency Injection 1.0.0 NuGet package:

public class ServiceConfigurator : IServicesConfigurator
{
    public void Configure(IServiceCollection serviceCollection)
    {
        serviceCollection.AddSingleton<BaseMediaManager>(s =>
            new MyMediaManager(
                new DefaultMediaManager(
                    s.GetService<BaseFactory>(),
                    s.GetService<MediaProvider>()
                )));
    }
}

Implementing Media Manager

You may inherit the DefaultMediaManager class as you mentioned but in case of numerous changes required (probably by different teams) composition might be a better choise):

public class MyMediaManager : BaseMediaManager
{
    private readonly BaseMediaManager _mediaManager;

    public MyMediaManager(BaseMediaManager mediaManager)
    {
        _mediaManager = mediaManager;
    }

    public override Media GetMedia(MediaItem item)
    {
        // add you custom logic here
        return _mediaManager.GetMedia(item);
    }
    ...
}

Registering Service Configurator

Last step, add the following registration to your configuration files:

<configuration>
  <sitecore>
    <services>
      <configurator type="<younamespace>.DependencyInjection.ServiceConfigurator, <yourassembly>"/>
    </services>
  </sitecore>
</configuration>
  • Thanks. I was able to override it. The method that I needed to add the text to is not in the media manager though I found out. I started another question for that. If I needed to change the URL though you answer works. – RReilley Jan 26 '18 at 14:08
