instance method
drop_enum
Ruby on Rails edge
Since v7.1.6Signature
drop_enum(name, values = nil, **options)Drops an enum type.
If the if_exists: true option is provided, the enum is dropped only if it exists. Otherwise, if the enum doesn’t exist, an error is raised.
The values parameter will be ignored if present. It can be helpful to provide this in a migration’s change method so it can be reverted. In that case, values will be used by #create_enum.
