If I have a table in MySQL on an existing Rails project, how do I go to
creating a migration for it? All the examples I see online seem to be
geared to creating models and tables from a migration – but how do I go
the other way and create a migration itself from a table? Thank you.

Why would you want to create a migration if you already have the table?

Look in the schema.rb. That’s your “up” method, and “down” is always the
same: drop_table :foo.

I have to commit my code changes on this specific project and it has to
comport to having a migration for a new db table that was required here.

could cobble one by hand, but I think that’s even more kludgey! I assume
it
isn’t possible to go from a table to a migration? Thanks.
