如何使用django模板递归提取分层字典？

I have hierarchical structure:

我有层次结构：

{
    "content": "Header 1", 
    "name": "folder/name.txt", 
    "decendent": [
         {
            "content": "Header 2", 
            "name": "folder/subfolder/name.txt", 
            "decendent": null
        }, 
        {
            "content": "Header 3", 
            "name": "folder/subfolder2/name.txt", 
            "decendent": [
                {
                    "content": "Header 4", 
                    "name": "folder/subfolder2/subsubfolder1/name.txt", 
                    "decendent": null
                }
                ... etc.
            ]
        }
    ]
}
