I've been using the Joomla extension DP fields to add fields to the joomla content model. The extension is great, I started using it after watching Macro Dings' talk at Joomla Day UK 2016 on YouTube.
So it is working really well for views in com_content, in terms of showing field values in article and blog views. However, I'm struggling to figure out how to display the data in a module or template override of a module.
For example, I'd like to show a couple of field values in a template override of the "mod_articles_category" module.
I was hoping there would be a helper and an class/api call to use from there, but I've not found one yet.
