ruby-on-rails - Rails as_json not including all associations

Question

For arguments sake, lets say I have legs as my object. I'm trying to call as_json on it and include all associations - which are set up correctly as it works perfectly in the console.

This is what I have:

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

For some reason it's not including right_shoe. It just stops at left_shoe. Any ideas?

Answer 1

我认为根据评论，您的右鞋处于错误的水平。尝试这个：

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

Have you ever try this gem, this is pretty cool to manipulate JSON model association:
