Rails包括不同級別的嵌套has_many關係

Question

所以，我有三個ActiveRecord模型。 On User是2個has_many關係，一個用於:accounts，另一個用於:authorizations，這是一組事務的別名。帳戶有一個:transactions的集合。

1. 用戶
2. 帳戶
3. 交易

到目前爲止，我已經能夠包括用戶，其:accounts和:transactions使用：

@user.to_json(:include => {:accounts => {:include => :transactions}})

I want to include the collection of transactions called :authorizations that User has as well. How can I do this?

Answer 1

您可以試試：

@user.to_json(:include => [{:accounts => {:include => :transactions}}, :authorizations])
