everything work as expected but not the part when the counter of a

I don't see how since:
if filename:
#update file counter
cur.execute('''UPDATE files SET hits = hits + 1, host = %s,
lastvisit = %s WHERE url = %s''', (host, lastvisit, filename) )
There isn'tmuch to say ehre. You already know the code that im using
inside files.pu and the question is that this execute never gets to execute.

filenames = []

presence

for row in data:

lastvisit = lastvisit.strftime('%A %e %b, %H:%M')

After a spcific file gets selected then files.py is reloading grabbign
the filename as a variable form and:
#
=================================================================================================================
# If user downloaded a file, thank the user !!!
#
=================================================================================================================
if filename:
#update filename's counter if cookie does not exist
cur.execute('''UPDATE files SET hits = hits + 1, host = %s, lastvisit =
%s WHERE url = %s''', (host, lastvisit, filename) )
but the execute never happesn.
i ahve tested it
if data:
print soemthing
but data is always empty.
