PyMongo TypeError - 文檔必須是dict，bson.son.SON或從集合繼承的其他類型的實例。可變映射

Question

當我試圖向MongoDB中插入一大塊GeoJSON時，我收到此消息：TypeError - document must be an instance of dict, bson.son.SON, or other type that inherits from collections.MutableMapping。

該塊是這樣的：

new_points = ['{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}', '{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}', '{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}', '{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}', '{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}', '{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}', '{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}', '{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}', '{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}', '{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}', '{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}', '{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}', '{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}', '{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}', '{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}', '{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}', '{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}', '{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}', '{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}', '{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}', '{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}', '{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}', '{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}', '{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}', '{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}', '{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}', '{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}', '{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}', '{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}', '{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}', '{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}', '{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}', '{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}', '{"coordinates": [-179.75, 89.75], "simulation": "aet_whe", "type": "Point"}'] 

而插入電話是這樣的：

result = points.insert_many(new_points) 

這本詞典與GeoJSON的文庫中產生的，採用這種結構：

class GenerateDocument: 
    def __init__(self, x, y, simulation_variable): 
     self.x = x 
     self.y = y 
     self.sim = simulation_variable 

    @property 
    def __geo_interface__(self): 
     return {'type': 'Point', 'coordinates': (self.x, self.y), 'simulation': self.sim} 

任何暗示解決這個問題？我是否生成錯誤類型的geojson？

使用建議：[json.loads(coords) for coords in new_points]上new_points變量解決了這個問題。
