Take current welcome app & add this to the bottom of models/db.py:
# Reusable author fields
authorstamp = db.Table(None, 'authorstamp',
Field('created_by', db.auth_user,
readable=False, # Enable when needed, not by
default
writable=False,
default=session.auth.user.id if
auth.is_logged_in() else 0,
represent = lambda id: (id and [db
(db.auth_user.id==id).select()[0].first_name] or ["None"])[0],
ondelete='RESTRICT'),
Field('modified_by', db.auth_user,
readable=False, # Enable when needed, not by
default
writable=False,
default=session.auth.user.id if
auth.is_logged_in() else 0,
update=session.auth.user.id if
auth.is_logged_in() else 0,
represent = lambda id: (id and [db
(db.auth_user.id==id).select()[0].first_name] or ["None"])[0],
ondelete='RESTRICT')
)
Errors with:
File "C:\Bin\web2py\gluon\sql.py", line 1501, in __init__
field.requires = sqlhtml_validators(field)
File "C:\Bin\web2py\gluon\sql.py", line 449, in sqlhtml_validators
referenced = field._db[field_type[10:]]
TypeError: 'NoneType' object is unsubscriptable
It's like db.auth_user doesn't exist yet!?
Many thanks,
Fran.
