[Nitro] RES: many to many - advanced relationships

[Antoniolo]

Just one more question:

class Personage
  property :nickname, String
  many_to_many :skills, :through => PersonageSkill
end

class Skill
  property :title, String
  many_to_many :skills, :through => PersonageSkill
end

class PersonageSkill
  property :value, Float
  has_one :personage
  has_one :skill
end

ok, that solves my previous problem, however I've got another one and here
as it follows:

me = Personage.new
me.nickname = 'antonio'

archery = Skill.new
archery.title = 'archery'

me.skills.add archery, :value => 45.5

me.save


Everything runs beautifully, except, the field 'value' doesn't save
anything. But, if I insert some saves before 'me.skills.add' like 'me.save'
and 'archery.save' it updates correctly.

My application needs to deal with not saving objects until world save timer
to trigger them. In fact, I've seen that Og does cascade saves ... but not
only with advanced many-to-many.

Do you have any solutions for that? 



Antonio.

Welcome to this list,

Yeah, this more or less works like AR, ie:

class Article
joins_many :first_join, Category, :through => ArticleToCategory
end

for more examples check out, og/test/og/tc_join.rb

regards,
George.
