Python Django 循环插入到 MongoDB数据库中

 单对单表关联：

开始先循环插入数据到MongoDB中，然后把表1的ID放到表2中，然后就可以通过表2来查看表1了

import random
import pymongo
'''DBRef关联的表'''
from bson.dbref import DBRef
from django.http import HttpResponse
from bson.objectid import ObjectId


def Circular_Insertion(request):
    # 链接mongo
    client = pymongo.MongoClient("127.0.0.1:27017")
    # mongo 数据库名字
    db = client.Chen

    cursor1 = db.zhan1.find({})
    cursor2 = db.zhan2.find({})

    '''循环插入到数据库的表中'''
    # 姓
    first_name = ["赵", "钱", "孙", "李", "周", "吴", "郑", "王", "冯", "陈", "褚", "卫", "蒋", "沈", "韩", "杨", "朱", "秦", "尤", "许",
                  "何", "吕", "施", "张"]
    # 循环插入的数量
    for i in range(3):
        first=random.sample(first_name,1)
        # 名  随机一万个字符
        last_names = chr(random.randint(0x4e00, 0x9fbf))
        name=first[0]+last_names
        # 成绩
        score1 = random.randint(0, 100)
        score2 = random.randint(0, 100)
        score3 = random.randint(0, 100)
        # 插入到数据库中的zhan1表中
        db.zhan1.insert_many([{'names': name, 'Subject': {"score1":score1,"score2":score2,"score3":score3,}}])
    # 遍历zhan1表
    for cur in cursor1:
        # 遍历zhan1表中的"_id"
        str1 = (cur["_id"])
        # 打印zhan1表
        print(cur)
        # 循环插入的数量
        for i in range(3):
            # 电话
            phone=('13' + str(random.randrange(4, 10)) + ''.join(str(random.choice(range(10))) for _ in range(8)))
            # 班级
            grade = random.randint(1, 3)
            # 年龄
            age = random.randint(1, 100)
            # 插入到数据库中的zhan2的表
            db.zhan2.insert_many([{'ref':DBRef(collection="zhan1",id=str1),'grades': grade,'ages': age,'phones': phone}])
            break

    print('-'*200)
    # 通过zhan2打印zhan1的信息
    for j in cursor2:
        show = db[j['ref'].collection].find({"_id": ObjectId(j['ref'].id)})
        for pt in show:
            print(pt)
            break
        print(j)
    return HttpResponse("数据插入成功！")
