Hi Adam,
I tried to install arches v3.1.2 and pointed the instance into our existing
database on settings.py, then I ran the export_resources command, which
produced those export files. However, the console update gave me this info:
(ENV4)ubuntu@PHMARCHES3PROD:~/Projects/phmapp312test$ python manage.py
packages -o export_resources -d v3fullexport.json
operation: export_resources
package: phmapp312test
Writing 5290 HERITAGE_RESOURCE.E18 resources
No module named PIL : 5290
Writing 3712 INFORMATION_RESOURCE.E73 resources
No module named PIL : 3712
Writing 2 ACTIVITY.E7 resources
No module named PIL : 2
Writing 4 HISTORICAL_EVENT.E5 resources
No module named PIL : 4
Writing 7 HERITAGE_RESOURCE_GROUP.E27 resources
No module named PIL : 7
Writing 8 ACTOR.E39 resources
No module named PIL : 8
When I checked the v3fullexport.json file it was almost empty. All it has
inside the file is this string:
{"resources":[]}
The v3fullexport.relations file is full of all the relationships.
I have a feeling I might be missing something here. Please let me know what
I should do further. Thank you.
Regards,
Joel
