在命令行中使用填充JSON文件蒙戈数据库在Python脚本

Posted 2023-01-16

page = open("npm.json", "r")
parsed = json.loads(page.read())

for i in parsed["dependencies"]:
    collection.insert_one(i)

你好，我想在一个JSON文件的读取和填充我与所谓ependencies.it一直给我和错误的行MongoDB的。我曾尝试插入，insert_one＆insert_many无济于事。

以下是错误我得到

    File "database.py", line 43, in <module>
    collection.insert_one(i)
  File "/usr/local/lib/python3.6/dist-packages/pymongo/collection.py", line 684, in insert_one
    common.validate_is_document_type("document", document)
  File "/usr/local/lib/python3.6/dist-packages/pymongo/common.py", line 453, in validate_is_document_type
    "collections.MutableMapping" % (option,))
TypeError: document must be an instance of dict, bson.son.SON, bson.raw_bson.RawBSONDocument, or a type that inherits from collections.MutableMapping
Error in sys.excepthook:

    import apt_pkg

Original exception was:

JSON文件是节点的依赖关系的列表。我跑了一个节点项目的命令列表NPM。任何人可以帮助在此先感谢

答案

它看起来像你的dependencies数据是dictionary。这意味着当您遍历它，你会得到的字符串（这是在这种情况下键）。

一个例子是，像这样：

my_entry = 'a': 1, 'b': 2

for i in myentry:
    print(i)

# will print 'a' then 'b', not 1 then 2

我假设每个依赖是一个关键，你要插入的值。所以

# dictionary.values() will give you just the values
for v in parsed['dependencies'].values():
    if isinstance(v, dict):
        collection.insert_one(v)
    else:
        raise ValueError("object is not dictionary")

蒙戈只需要json或bson条目，这是像字典。当你通过keys，你想插入式string，它不支持的对象
