Rails as_json不包括所有关联

Question

为了参数的缘故，可以说我有双腿作为我的对象。我试图调用as_json并包含所有关联 - 这些关联正确设置，因为它在控制台中完美工作。

这是我有：

@legs.as_json(
    :include => { 
    :shoes => { 
     :include => { 
     :left_shoe => { 
      :include => { 
      :shoe_lace => {:include => :sock} 
      } 
     } 
     }, 
     :right_shoe => { 
     :include => { 
      :shoe_lace => {:include => :sock} 
     } 
     } 
    } 
    } 
) 

出于某种原因，它不包括right_shoe。它只停留在left_shoe。有任何想法吗？

我认为根据评论你的右鞋是在错误的水平。试试这个：

@legs.as_json(
    :include => { 
    :shoes => { 
     :include => { 
     :left_shoe => { 
      :include => { 
      :shoe_lace => {:include => :sock} 
      } 
     }, 
     :right_shoe => { 
      :include => { 
      :shoe_lace => {:include => :sock} 
      } 
     } 
     } 
    } 
    } 
)
