python - django:无法将模型导入到与模型相同路径上的.py

Question

我已经阅读了 SO 上的所有内容以及所有正在寻找解决方案的 django 文档。我的模型工作得很好，但我无法将它们导入到与 models.py 位于同一目录中的“getnews.py”文件中，我可以导入到views.py 中，并且绝对没有循环导入!

模型.py:

from django.db import models

import datetime
from django.utils import timezone

class newsurls(models.Model):
    title = models.CharField(max_length=200)
    def __unicode__(self):
        return unicode(self.title)
    pub_date = models.DateTimeField("date published")



class newsblock(models.Model):
    news = models.ForeignKey(newsurls)
    url = models.URLField(max_length=2000)
    def __unicode__(self):
        return unicode(self.url)
    image = models.URLField(max_length=2000)
    favi = models.URLField(max_length=2000)
    bgcolor = models.CharField(max_length=20)
    tcolor = models.CharField(max_length=20)
    genre = models.CharField(max_length=200)

在views.py中:(有效)

from news.models import newsurls, newsblock 

getnews.py:(不起作用)

from news.models import newsurls, newsblock

回溯:

Traceback (most recent call last):
File "/home/skru/newsshuffle/news/getnews.py", line 3, in <module>
from news.models import newsurls, newsblock
ImportError: No module named news.models

views.py:

from django.shortcuts import render_to_response
from news.models import newsurls, newsblock
try:
    import cPickle as pickle
except:
    import pickle
import random

def news(request):
    newsDatabase = open('/home/skru/newsshuffle/news/storyDb.p', 'r+')
    openData = newsDatabase.read()
    dstory = pickle.loads(openData)
    count = dstory['count']['links']
    story = []
    outstorys = []
    keys = dstory.keys()
    for key in keys:
        if key != 'count':
            story.append(dstory[key]['genre'])
            story.append(dstory[key]['title'])
            story.append(dstory[key]['url'])
            story.append(dstory[key]['image'])
            story.append(dstory[key]['bgcolor'])
            story.append(dstory[key]['via'])
            story.append(dstory[key]['tcolor'])
            outstorys.append(story)
            story = []

    random.shuffle(outstorys)


    lists = newsurls.objects.order_by('-pub_date')[:100]
    return render_to_response('news/news.html',
                          {
                          'story_list':outstorys,
                          'count':count,
                          'lists':lists,
                          })

文件路径:

 ├── manage.py
 ├── news
 │   ├── static
 │   │   └── news
 │   │       ├── news.css
 │   │       └── ...

 └── newsshuffle
     ├── __init__.py
     ├── settings.py
     ├── urls.py
     └── wsgi.py

我尝试了各种不同的导入“newsshuffle.news.models”等..，按照其他提要中的建议，手动将系统路径添加到系统路径，请帮忙!!

管理.py:

#!/usr/bin/env python
import os
import sys

if __name__ == "__main__":
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "newsshuffle.settings")

    from django.core.management import execute_from_command_line

    execute_from_command_line(sys.argv)

添加此内容是因为 SO 上的大多数其他帖子都指出必须手动设置 DJANGO_SETTINGS_MODULE 但正如您所看到的那样

鉴于该目录结构，您的导入应该可以正常工作。

尝试相对导入怎么样？在 views.py 和 getnews.py 中，这个应该工作:

from models import ...
