excuseme if this question can (seem to) be stupid, but I don't figure how to solve...
Shortly, my custom module:
- exposes a node type
- exposes an entity type
- attach to that node a field containing a set of these entities (by using entity_reference)
I would like to customise how those entities are visualised in the node view page: I would like to show more info instead of just the entity label.
I read something about
hook_field_formatter_info(), that seems to be the best solution, but my debugger suggests that is not invoked (neither after a cache clear)... on the other I can't find any info about how to explain this to
The ideal behaviour should be to tell to Drupal:
- use a specific template file to render all fields belonging to a given field instance
- allow a theme to override that representation in a new template file
Do you have a snippet of code or a web resource explaining how to instruct my module to do this?
