单独的 python 脚本文件使用 django 自带的 model

django1.9.5&python3.4.4文件结构在一个爬虫脚本中将爬取的数据通过django自带的model保存到数据库修改的文件(其余pycharm新建Django项目生成,未修改):

# testapp/models.py

from django.db import models

class Problem(models.Model):

title = models.CharField(max_length=100, default="")

author = models.CharField(max_length=100, default="")

    def __str__(self):        return self.title

pass

# testapp/spider.py

import os

import sys

import django

pathname = os.path.dirname(os.path.abspath(__file__))

sys.path.insert(0, pathname)

sys.path.insert(0, os.path.abspath(os.path.join(pathname, '..')))

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

django.setup()

from testapp.models import Problem

if __name__ == "__main__":

p = Problem(title="hi", author="hi")

p.save()

pass

# testproject/setting.py

......

INSTALLED_APPS = [

'django.contrib.admin',

'django.contrib.auth',

'django.contrib.contenttypes',

'django.contrib.sessions',

'django.contrib.messages',

'django.contrib.staticfiles',

# 添加应用

'testapp',

]

......

# testapp/admin.py 在后台管理界面注册 Problem

from django.contrib import admin

# Register your models here.

from testapp.models import Problem

admin.site.register(Problem)

运行spider.py,添加一条实例记录运行Django项目, 创建管理员账号, 后台管理界面查看结果参考:http://stackoverflow.com/questions/17787365/from-django-db-import-models-is-broken-in-a-django-standalone-crontab-script
