Question

我有一个用户模型，它为一个名为profile_img的字段安装了一个载波上传器。代码：

class User < ActiveRecord::Base
    mount_uploader :profile_img, ProfileUploader
end

profile_img字段的输出如下：

"profile_img": {
            "url": "https://halo-img-dev.s3.amazonaws.com/uploads/user/profile_img/1000/cola_iOS2_512_dribbble2.png",
            "thumb": {
                "url": "https://halo-img-dev.s3.amazonaws.com/uploads/user/profile_img/1000/thumb_cola_iOS2_512_dribbble2.png"
            },
            "medium": {
                "url": "https://halo-img-dev.s3.amazonaws.com/uploads/user/profile_img/1000/medium_cola_iOS2_512_dribbble2.png"
            }
        }

当我尝试通过简单调用super来自定义序列化哈希时，

def serializable_hash(options = {})
    super(options)
end

profile_image字段键重复

"profile_img": {
        "profile_img": {  #### duplicate here
            "url": "https://halo-img-dev.s3.amazonaws.com/uploads/user/profile_img/1000/cola_iOS2_512_dribbble2.png",
            "thumb": {
                "url": "https://halo-img-dev.s3.amazonaws.com/uploads/user/profile_img/1000/thumb_cola_iOS2_512_dribbble2.png"
            },
            "medium": {
                "url": "https://halo-img-dev.s3.amazonaws.com/uploads/user/profile_img/1000/medium_cola_iOS2_512_dribbble2.png"
            }
        }
    },

我怀疑这个问题源于carrierwave序列化方法，但无法找到解决方案。

任何线索？

解决方案：

<强> JBUILDER

json.profile_img @user.profile_img.serializable_hash

<强> ActiveModelSerializer

# attributes
def profile_img
  object.profile_img.serializable_hash
end

serializable_hash中的carrierwave双键

任何线索？
