This is normal behaviour. syncdb does nothing if the table already
exists - in other words it works only once to create a new table
deliberately in case you have inserted data. You wouldn't want it to
repeat a create and wipe out your data.

If it doesn't discover any new tables to create it reports 'No fixtures
found'

If you want to adjust a table this means you need to dump all data in
the table to a receptacle somewhere, change the defining class in
models.py then drop the table and run syncdb again. Finally you need a
script to adjust your dumped data and pump it back into the new table.
This is a very common process and Google will help when you need to do it.
