How to divide revisions by folders? #1772

Do you want to add an issue for this? I think it's fine adding a mkdir(..., exists_ok=True) there unconditionally

yeah it's something we can do with the Path when we set up the destination

I tried again, and it worked. Btw, not setting revision_environment also worked for me.

I will create issue, and also create PR. Just to clarify, I should add mkdir to script/base:ScriptDirectory:_rev_path right?

not setting revision_environment recursive_version_locations wont prevent the directory from being created. it will prevent subsequent alembic commands from seeing your file.

As far as issue / PR it's already done and merged: #1774 merged in fd42cdd

that comment referred to recursive_version_locations. revision_environment only applies if you run revision without --autogenerate. so while you might not ever run without the autogenerate flag, it's probably a good idea to have it, otherwise if it ever does run without that option, the directory wont get created.
