Am I missing any special way of inserting model instances with cyclic
references? Anything better than the following?
require 'sequel'
DB = Sequel.sqlite
DB.create_table :foos do
primary_key :id
foreign_key :bar_id, :bars
end
DB.create_table :bars do
primary_key :id
foreign_key :baz_id, :bazs
end
DB.create_table :bazs do
primary_key :id
foreign_key :foo_id, :foos
end
class Foo < Sequel::Model
many_to_one :bar
one_to_many :baz
end
class Bar < Sequel::Model
many_to_one :baz
one_to_many :foo
end
class Baz < Sequel::Model
many_to_one :foo
one_to_many :bar
end
defer = []
Foo.create do |foo|
foo.bar = Bar.create do |bar|
bar.baz = Baz.create do |baz|
defer << proc do
baz.foo = foo
baz.save
end
end
end
end
defer.each do |d|
d.call
end
p Foo.all
p Bar.all
p Baz.all
