DD4T - How to fetch nested embedded fields in Razor?

Question

My XML structure looks like this:

• links
  • title
  • image
  • internal_link (Component Link)
    • headline
    • type
    • section

I want to fetch the field headline of internal_link.

I am using the following code:

<div id="verticalNav">
   @if (Model.Component.Fields.ContainsKey("links")
   {
      foreach (var lnk in Model.Component.Fields["links"].EmbeddedValues)
      {
         if (lnk.ContainsKey("internal_link"))
         {
            foreach (var intlnk in lnk["internal_link"].LinkedComponentValues)
            {
               if (intlnk.Fields.ContainsKey("headline"))
               {
                  <p>intlnk.Fields["headline"].Value</p>
               }
            }
         }  
      }
   }
</div>

However, it's failing to check the condition intlnk.Fields.ContainsKey("headline"). Yet field headline has a value.

I increased the value of the linklevels to 4, but still it is not working. Did I miss anything?

Answer 1

The LinkLevels parameter in your TBB has to be set accordingly to include nested Component Links.

After any change in a Template or in the Component content, you will need to publish these changes for them to appear on the delivery side.

Since you mentioned you did make a change in the link levels, I'm assuming you haven't Published all Components using the Component Template you have changed the LinkLevels in, or maybe you tried Publishing a Template which was still checked out (open in the Template Builder for example). These are common causes for changes not to appear on the delivery side.
