使用jq获取特定键的所有父键

Question

我想要做的是在我的 json 上“行走”，并为每个名为“base”的键添加一个键，该键是该键的完整“路径”。

这是我的 JSON：

{
  "entity": {
    "product": {
      "att": {
        "number_of_values": "Number of values"
      },
      "title": {
        "base": ["product", "products", "pdt", "pdts"]
      }
    },
    "rabbit": {
      "att": {
        "number_of_values": "Number of values"
      },
      "title": {
        "base": ["rabbit", "rabbits"]
      }
    }
  }
}

我想要这样的结果：

{
  "entity": {
    "product": {
      "att": {
        "number_of_values": "Number of values"
      },
      "title": {
        "base": ["product", "products", "pdt", "pdts"],
        "path": "entity.product.title"
      }
    },
    "rabbit": {
      "att": {
        "number_of_values": "Number of values"
      },
      "title": {
        "base": ["rabbit", "rabbits"]
        "path": "entity.rabbit.title"
      }
    }
  }
}

实际上，我实现了这一点，但我只得到一个子密钥：

walk(if type == "object" and .base then  keys[] as $k | .base |= {path: $k} else . end)

结果：

{
  "entity": {
    "product": {
      "att": {
        "number_of_values": "Number of values"
      },
      "title": {
        "base": {
          "path": "base"
        }
      }
    },
    "rabbit": {
      "att": {
        "number_of_values": "Number of values"
      },
      "title": {
        "base": {
          "path": "base"
        }
      }
    }
  }
}

我也尝试过这个：

walk(if type == "object" and .base then  paths(..) as $v | .base |= {path: $v} else . end)

结果：

{
  "entity": {
    "product": {
      "att": {
        "number_of_values": "Number of values"
      },
      "title": {
        "base": {
          "path": [
            "base",
            3
          ]
        }
      }
    },
    "rabbit": {
      "att": {
        "number_of_values": "Number of values"
      },
      "title": {
        "base": {
          "path": [
            "base",
            1
          ]
        }
      }
    }
  }
}

非常感谢您的建议和专业知识！

这是一种方法：

reduce paths(objects | has("base")) as $p (.;
  setpath($p + ["path"]; $p | join("."))
)
