Hi James,

I'm attaching the stacktrace as you requested.

Thanks. It is quite telling:

  File "/home/jja/testenv3.5/lib/python3.5/site-packages/django/db/backends/sqlite3/base.py", line 337, in execute      return Database.Cursor.execute(self, query, params)  django.db.utils.IntegrityError: UNIQUE constraint failed: siggy_stemplate.name

The object you are working with is having a 'name' clash with another object of the same type. You've set the 'name' field to be unique, so you'll need to ensure that each object has a unique value for the 'name' field. Either check for uniqueness before assigning it, or attempt to save, catch this exception, and generate a more unique value as needed, rinse and repeat as necessary.
