Complex resource generation?

Hey guys, I'm getting a bit of chicken & egg problem when I try to create my resources using generators. As most of them are somehow related to one another, I get all sorts of compile time errors, no matter which ones I try to run first. How do you handle these situations yourselves? Is it at all possible to build my app using generators, or do I have to manually write most of them?

For example, a Subtitle belongs to a Video, and a Video has many Subtitles. Whenever I try to crate one, the othe must be already present, otherwise I get an error. Maybe I'm doing something wrong?

mix ash.gen.resource Susflix.Media.Video --uuid-primary-key id --relationship "has_many:subtitles:Susflix.Media.Subtitle"
mix ash.gen.resource Susflix.Media.Subtitle --uuid-primary-key id --relationship "belongs_to:video:Susflix.Media.Video"
