在Django中运行python manage.py syncdb时出现syncdb错误

Question

我正在跟着一个Django的教程，但我检查了三遍所有的东西，还是不行，这里是我得到的结果……我哪里做错了？

python manage.py syncdb
Traceback (most recent call last):

这是我在DATABASES里的内容

 DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
    }
}

这是来自应用stories的models.py，也许我这里有什么没注意到的？

from urlparse import urlparse
from django.db import models
from django.contrib.auth.models import User

class Story(models.Model):    
    title = models.CharField(max_length=200)    
    url = models.URLField()    
    points = models.IntergerField()    
    moderator = models.ForeignKey(User)    
    created_at = models.DateTimeField(auto_now_add=True)    
    updated_at = models.DateTimeField(auto_now=True)    

    @property
    def domain(self):
    return urlparse(self.url).netloc    

Answer 1

你还没有在 settings.py 文件中设置数据库的引擎选项。

这个文件会和你运行 manage.py 的目录放在一起。

'NAME': 'data.sqlite',

这会给出数据库的文件名和你的位置。

'NAME': '/yourpath/mysite/data.sqlite',

最好的做法是传递一个绝对路径，像这样：

import os

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

还有 NAME 选项，像这样：

'NAME': os.path.join(SETTINGS_DIR, 'data.sqlite'),

Answer 2

在我使用的管理者模型中，我有：

points = models.IntergerField()

结果发现“Inte(r)gerField”这个东西不存在！哈哈，我打错字了。我已经把它改成：

points = models.IntegerField()
