When using Alembic autogenerate command, we need to add a new module (mymodule)
to $PYTHONPATH, and then configure env.py. $PYTHONPATH seems not stable. When I
open an ubuntu terminal, and type: export
PYTHONPATH=$PYTHONPATH:/home/mydir/mymodule, the new module is added into
$PYTHONPATH variable. autogenerate command worked fine. But when I open a new
ubuntun terminal, and check $PYTHONPATH, the new module mymodule was not there,
and autogenerate command didn't work under this terminal. I don't know what is
wrong.
Another problem I encountered: I am one of users in an Ubuntu OS, and I can use
'sudo bash' to get root permission. Another user, let us call usersupper, who
installed alembic in that Ubuntu OS, but didn't configure it. I used root
permission to configure it. THere is no problem to run 'alembic revision -m
"create account table"', but failed to run 'alembic revision --autogenerate',
and got error:
......
module = imp.load_source(module_id, path, open(path, 'rb'))
File "alembic/env.py", line 20, in <module>
from mymodule import myschema
ImportError: No module named mymodule
but I did run command 'export PYTHONPATH=$PYTHONPATH:/home/mydir/mymodule'
successfully. Is that permission problem?
Please let me know if I didn't explain the problem clearly.
Thanks a lot in advance!
