Paolo,
I think you've going in the right direction but i'd recommend a few changes based on my experience. Translation Agency has different rates for each language. and the rate per language for A -> B Is not the same as B -> A. So its better to maintain the cost details in Another model unique for one direction.
Language:
has_many :language_translations
LanguageTranslation
belongs_to :language
belongs_to :target_language, :class_name => "Language"
#An float/integer field for cost.
Also i dont think you have to specify foreign_key condition unless your association name and foreignkeys are different..
eg blongs_to :car, :class_name => "Vehicle", :foreign_key => "bus_id"
If you have car_id as the foreign key. then you can ignore mentioning it in the model.
Cheers

Hi to all.--
I am working for a translation agency and I have the task to create an auto-estimate system and ordering/invoicing administration system. I am stuck on how to manage the language pairs.
I created a Language model with the language name and a LanguagePair with a source language, a target language and a rate per words attributes. I tried with:
LanguagePair
belongs_to :source, :class_name => "Language", :foreign_key => "source_id"
belongs_to :target, :class_name => "Language", :foreign_key => "target_id"
and also by replacing the source and target in the LanguagePair with a string type and loading it with a Language.all.permutation(2).to_a and eliminate the need for nesting.
In the end I will create a sort of cart and lineitem model and add the LanguagePair to the cart as a LineItem.
Is there a "best" way to do this maybe with a Language self-referential model?
thanks in advance
