我已经解决了所有关于此问题的各种问题,但都没有解决我的问题。我正在使用Python 2.7在Windows 7家用计算机上使用最新版本的django,virtualenv开发django项目。该项目意味着在Heroku上运行,但它在本地也不起作用。
基本上,当尝试运行manage.py sqlall appname
时,它总是返回以下错误树:
Traceback (most recent call last):

它甚至不会识别一个全新的,未被触及的应用程序。例如,如果我运行manage.py startapp tryagain
然后将'tryagain'
添加到INSTALLED_APPS
,则在尝试manage.py test tryagain
之类的内容时仍会出现相同的错误。我的settings.py
文件与普通文件不同的唯一方法是,对于Heroku,我添加了以下两行:
import dj_database_url
DATABASES = {'default': dj_database_url.config(default='postgres://localhost')}
非常感谢任何帮助。我在这里疯狂。
编辑:
首先,我尝试使用一个全新的应用程序启动一个全新的Django项目,它仍然无法正常工作,即使一切都完全不受影响。
由于我无法弄清楚哪些设置是相关的,因此我为我的麻烦项目提供了以下整个settings.py

第三次修改
我认为当我运行manage.py syncdb
时,我会收到以下错误:

另一个编辑:
根据要求,这是我的models.py
。
# models.py
from django.db import models
# Create your models here.
class listing(models.Model):
body = models.CharField(max_length=10000)
title = models.CharField(max_length=400)
url = models.URLField(primary_key = True)
scraping_time = models.DateTimeField()
phone = models.CharField(max_length=20)
posting_time = models.DateTimeField()
email = models.EmailField()
# imglist as separate model
def __str__(self):
return self.title
class imagelist(models.Model):
listing = models.ForeignKey(listing)
img_url = models.URLField()
def __str__(self):
return self.img_url
答案 0 :(得分:3)
经过一番头痛之后,我才明白了。
出于某种原因,有两个settings.py
s - 整个项目目录craigslist
中的一个,以及子目录craigslist\craigslist
中的一个,我正在编辑顶级{ {1}},我本来应该编辑下面的那个。我不知道为什么会这样,但是在将所有代码从顶级复制到子级别之后,突然settings.py
工作了。
答案 1 :(得分:0)
在我的情况下,我的问题是我修改了我的DJANGO_SETTINGS_MODULE,但仅在我的gunicord设置文件(/ webapps / run / gunicorn_start)中更改了它。 所以&#39; python mange.py&#39;仍然指的是旧的settings.pyc文件(&#39; py&#39;文件已被删除,但&#39; pyc&#39;仍然是......)。
完成以下操作后,一切正常: 导出DJANGO_SETTINGS_MODULE = ...
