Question

我有一个由同事开发的Mongo数据库，当我上载到Pandas数据框时，该数据库不会显示一半字段，而另一部分则显示为字符串。

尽管我对蒙哥并不太了解，但我还是尝试浏览蒙哥的结构。我还尝试使用collection.find（）来显示错误。

这是我的python（PyMongo和Pandas）代码：

client = MongoClient("(String of Mongo DB")
db = client.Project
collection = db.users

df = pd.DataFrame(list(collection.find()))

df.to_excel(writer, sheet_name='tester')
writer.save()
print(df)

这是MongoDB的结构：

var transactions = mongoose.Schema({
    date: Date,
    type: String,
    description: String,
    debit: String,
    credit: String,
    currency: String,
    balance: String
})
var userSchema = mongoose.Schema({
    local: {
        email: String,
        name: String,
        profilePic: String,
        username: String,
        password: String,
        birthDate: Date,
        img: String,
        firstTime: Boolean,
        dateCreation: Date,
        gender: String,
        maritalStatus: String,
        country: String,
        cardP: {
            current: String,
        },
        accounts: [{
            id: Number,
            name: String,
            bankName: String,
            img: String,
            number: Number,
            profile: String,
            iban: String,
            balance: Number,
            transactions: [transactions]
        }],
        profiles: [{
            id: String,
            text: String
        }],
        alerts: [{
            id: Number,
            title: String,
            text: String
        }]
    },
});

我希望有几个列的数据框会出现，但这出现了：

__v: 0
_id: 5cf7f08a6721e016203af46c
local:{'accounts': [{'_id': ObjectId('5d00c3fd7b7b631b982d64be'), 'id': 123567, 'name': 'Bank', 'img': ' (and a lot more of fields)

将MongoDB字符串转换为多个Pandas列
