Thanks for all the help so far! Now that I got the userID and filename
in the table, I'm having problems populating the other fields. I have
been trying to run queries, but i'm not sure I completely understand the
syntax allowed in the controller yet. Eitherway, these are the last two
issues I've been having:
Recall the models:
------------------------------------
db.define_table('version',
Field('application_id', db.application),
Field('vers'),
Field('Release_Date', 'date'),
Field('opSystem'),
Field('reqs'),
Field('changeLog', 'text'),
Field('fileS', 'upload'))
db.define_table('userSoftware',
Field('user_id', db.auth_user, writable=False),
Field('application_id', db.application),
Field('version_id', db.version),
Field('Release_Date', db.version),
Field('Filename'))
------------------------------
I tried the following:
------------------------------
appVer = db(db.version.fileS ==
request.args(0)).select(db.version.Release_Date)
if not (db(queryID).update(Filename=request.args(0))) :
db.userSoftware.insert(user_id =
auth.user_id,Filename=request.args(0), Release_Date=appVer.Release_Date)
-------------------------------
I keep getting the follow traceback, which states that no field
'Release_Date' exists
Traceback (most recent call last):
File "/home/matthewm/Downloads/web2py/gluon/restricted.py", line 173, in

return action(*a, **b)

line 82, in download
db.userSoftware.insert(user_id = auth.user_id,Filename=request.args(0),
Release_Date=appVer.Release_Date)
AttributeError: 'Rows' object has no attribute 'Release_Date'
Any idea why that is the case?
