[django]Django model中数据批量导入bulk_create()

参考: https://www.cnblogs.com/ccorz/p/Django-model-zhong-shu-ju-pi-liang-dao-rubulkcreat.html

import os

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "toupiao.settings")

import django

django.setup()

## 方法1: 串行创建
# def main():
#     from app03.models import Question
#     f = open('db.db')
#     for line in f:
#         Question.objects.create(question_text=line)
#     f.close()
#
#
# main()

## 方法2: 并行创建bulk_create
def main2():
    from app03.models import Question
    f = open('db.db')
    question_list = []
    for line in f:
        quesiton = Question(question_text=line)
        question_list.append(quesiton)
    f.close()
    Question.objects.bulk_create(question_list)

main2()

tips: 使用get_or_create()可以防止插入数据重复
