Rails 3渲染json并包含来自数组的配置文件

Question

所有用户都有一个配置文件。

目前

:

render :json => @user, :include => [:friends, :requested_friends]

希望包含好友和请求好友的个人资料。

我知道对于单个include，我可以使用这个

render :json => @user, :include => {:requested_friends => {:include => :profile}}

但需要一些像:

render :json => @user, :include => {[:friends, :requested_friends] => {:include => :profile}}

Answer 1

如何:

render :json    => @user,
       :include => {
           :requested_friends => { :include => :profile },
           :friends           => { :include => :profile }
       }
