There's no validates_associated. You shouldn't be associating invalid objects to your models, but checking that the objects themselves are valid before associating them (which saving them will do by default). > For example, if each Photo can have many Tags, I'd like to validate > the presence of at least one Tag.

The above should do it. > I don't have a problem with doing it manually, I'm just wondering if > Sequel supports this somehow out of the box. I guess it does, though it may not be intuitive.
