[ckan-dev] Extending template extensions

Mon Mar 7 15:26:48 UTC 2016

You've got a couple options. The simplest is to create a template
named scheming/package/resource_read.html that uses {% ckan_extends %}
and override the blocks you need. This template must be in a template
directory added from a plugin that appears *before* scheming in the
plugin lists or it won't affect anything.

Another option is to subclass the SchemingDatasetsPlugin class, use
your subclass plugin instead of scheming, and override the
resource_template method to point to your new template. I'd only
recommend this option if you need to change something else about the
way the scheming internals work.
