Okay, I had a legacy table that had no versioning. I added Acts As  
Versioned, by adding the “version” column to said database, and adding  
the acts\_as\_versioned to the model. When I tried to “save()” a record,  
I got an “uninitialized constant ActiveRecord::Table::Version” The  
field existed in the database, and the table\_versions table was there.  
When I used “save\_without\_revision()”, the record saved without a  
problem.

Any clue on what I need to do to fix this?

aav also requires an xxx\_versions table (e.g., foo\_versions if you’re  
versioning foos). Check the documentation; there’s a class-level  
method added to models that acts\_as\_versioned that will create the  
version table for you if you add it to a migration.

Sorry for the delay answering. There is a xxx\_versions table.

Crud. I think I see the problem. This is a legacy db, which has a  
table named ‘bases,’ which is a naughty table name. The singular is  
‘basis,’ which I can’t inflect because it’s a (kinda) reserved name.

So, I guess I can magically rename the table “basis\_versions” and fix  
it. I’ll give it a whirl.
