Hi all
I have solved the problem I described below. I just guessed at the solution
after
reading Ticket #3413 (closed: invalid). In that case a class object was being
passed
as a param to the database instead of a user id. And indeed clue was the full
error
message in the traceback ....
/usr/lib/python2.3/site-packages/django/db/backends/sqlite3/base.py in execute
params: [<User: play>, 14]
query : 'UPDATE "lab_data" SET "who"=? WHERE "id"=?' self
<django.db.backends.sqlite3.base.SQLiteCursorWrapper object at 0x40577aac>
I therefore have changed:
self.who = threadlocals.get_current_user()
to:
self.who = str(threadlocals.get_current_user())
and now I get the usernmame updated correctly and no errors.
I am using Django 0.97-pre, SVN 5754
