I'm using the feeds module to pull in a set of publications into a Drupal content type. I have two separate feeds, which I hoped would work as follows:
Feed 1 - pulls in most of the fields
Feed 2 - accesses a separate url source and updates one field on the content type.
The problem I have is that feed 2 always creates a new set of nodes rather than updating the existing nodes (that were created using feed 1), despite the GUIDs being identical. I have looked at the feeds_items database table and it appears that each feed creates it's own set of GUID to entity_id mappings.
What I want to achieve is one of the following:
1. Allow feed 2 to update the same nodes as feed 1.
2. Allow both URL sources to be used in one feed.
Is there any way to do this with custom code or otherwise?
