alembic/env.py target_metadata = metadata "No module name al_test.models" -


when use alembic control version of project's database,part of codes in env.py like:

# add model's metadata object here # 'autogenerate' support # myapp import mymodel # target_metadata = mymodel.base.metadata al_test.models import metadata  target_metadata = metadata

when run 'alembic revision --autogenerate -m "added user table"', error : file "alembic/env.py", line 18, in al_test.models import metadata importerror: no module named al_test.models

so how solve question? thanks!

this might bit late, , may have figured out issue, guess problem alembic/ directory not part of system path. i.e. need like:

import sys sys.path.append(path/to/al_test)  al_test.models import metadata
