安装 Python 2.7.2 和 Django 1.5 并创建我的第一个应用程序的第二天,现在我无法同步 models.py 并更新我的数据库。

工具:Windows Vista、Putty SSH 位置:Bluehost (www.bluehost.com) 服务器

这是我已经阅读但没有解决我的问题的主题: Why did I get error for python manage.py syncdb (IndentationError: unexpected indent)

建议是关于 models.py 中的制表符和空格缩进),但请相信我使用了正确的缩进,如下所示(models.py)。

from django.db import models

# Create your models here.

class posts(models.Model):

    author = models.CharField(max_lenght = 30)
    title = models.CharField(max_lenght = 100)
    bodytext = models.TextField()
    timestamp = models.DateTimeField()

我已经做了什么:

我已经安装了 Python 2.7.2,请检查:

username@domain.com [~]# python -V
Python 2.7.2 

我已经安装了 Django 1.5,检查

username@domain.com [~]# python
Python 2.7.2 (default, Mar 27 2013, 12:07:49)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-3)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from django import get_version
>>> get_version()
'1.5'
>>>

我已经安装了 MySQL-python-1.2.4 (在这一点上我不确定它是否正常工作):

username@domain.com [~]# python
Python 2.7.2 (default, Mar 27 2013, 12:07:49)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-3)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import MySQLdb
>>>

我遇到了 django-admin.py 的问题,通过更改 .bashrc PATH 条目解决了它,并成功运行了colde:

django-admin.py startproject mysite

然后我像这样修改了models.py(创建一个简单的博客):

from django.db import models

# Create your models here.

class posts(models.Model):

    author = models.CharField(max_lenght = 30)
    title = models.CharField(max_lenght = 100)
    bodytext = models.TextField()
    timestamp = models.DateTimeField()

然后我创建了一个mysql 数据库和一个用户,将用户添加到数据库并赋予所有权限(全部在 bluehost 前端面板中完成)。

然后我像这样修改了settings.py

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql', # Add 'postgresql_psycopg2', 'mysql', 'sqlite3' or 'oracle'.
        'NAME': 'domain_dbname',                      # Or path to database file if using sqlite3.
        # The following settings are not used with sqlite3:
        'USER': 'domain_username',
        'PASSWORD': 'password',
        'HOST': '',                      # Empty for localhost through domain sockets or '127.0.0.1' for localhost through TCP.
        'PORT': '',                      # Set to empty string for default.
    }
}

问题

现在是更新数据库的时候了,我试试这个:

python models.py syncdb

这就是我得到的:

Traceback (most recent call last):
  File "models.py", line 1, in <module>
    from django.db import models
  File "/home1/domain/python/lib/python2.7/site-packages/django/db/__init__.py", line 11, in <module>
    if settings.DATABASES and DEFAULT_DB_ALIAS not in settings.DATABASES:
  File "/home1/domain/python/lib/python2.7/site-packages/django/conf/__init__.py", line 52, in __getattr__
    self._setup(name)
  File "/home1/domain/python/lib/python2.7/site-packages/django/conf/__init__.py", line 45, in _setup
    % (desc, ENVIRONMENT_VARIABLE))
django.core.exceptions.ImproperlyConfigured: Requested setting DATABASES, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

所以我的问题是:

为什么这条线不起作用?

python models.py syncdb
