@pbanaszkiewicz In this case, the error about line too long refers to the generated migration file. Do you fix these migration files or ignore the error?

I tried using ruff to format the lines but am still getting the error (to different lines now since some formatting was applied).

@maneesha You can break a long string like this:

                        "Hotel and airfare will be booked by site; ground travel and"
                        " meals/incidentals will be reimbursed within 60 days."

The important thing is that there is no comma between the strings and it only works in brackets/parens.
