alembic how to merge all revision files to one file?

There are more than 100 files in alembic version directory. How to use alembic command to merge these file into a one file?

I am try to use this:

alembic revision --autogenerate

but doesn't work! Anyone has good idea?

Solution

  • If you have all the models in models.py (or whatever you use for models), it should be possible to achieve your goal by recreating migrations in a single file. Like this:

    1. Point Alembic to a different and empty database
    2. run alembic revision --autogenerate
    3. You'll get the mirroring revision in a single file.
