many-to-many relation with additional data

[Pierre Letier]

Hello,

I am looking to implement a many to many relation in Elixir with
Additional Data.

Eg:

I have a table of Items and a table of Orders, with a Many-to-Many
relation between them. I want to associate a given price to a specific
association between an Item and an Order. How can I define this with
Elixir ? Can you provide me a sample of code doing that with Elixir ?

Thank you
