For next time: most oil scripts come with a '-h' or '--help' parameter, that shows you the syntax.
In the case of fromdb:
Description: Run scaffolding or generate a model from existing database table(s). Database settings must be configured correctly for this to work.
Runtime options: -f, [--force] # Overwrite files that already exist -s, [--skip] # Skip generating files that already exist -a, [--admin] # Generate admin scaffolding code --all # Generate code for all tables found in the database --db=<database> # Name of the database to use
I added fromdb:migration earlier this week, but it's still very basic. I created an issue to keep track of what is still missing (which is substantial).
