#apps/user/user.py

from django.core import meta
class User(meta.Model):
    username=meta.CharField('用户名',maxlength=50,primary_key=True,core=True)
    password=meta.CharField('密码',maxlength=50,core=True)
    email=meta.EmailField('电邮地址',db_index=True,core=True)
    nickname=meta.CharField('昵称',maxlength=30,core=True)
    regdate=meta.DateTimeField("注册时间",auto_now_add=True,core=True)
    lasttime=meta.DateTimeField("上次登录时间",auto_now=True,core=True)
    photo=meta.ImageField("用户照片",default='None.jpg
',upload_to='userphoto',height_field=240,width_field=320,core=True)
    regip=meta.IPAddressField("注册时的IP地址",core=True)
    lastip=meta.IPAddressField("上次的IP地址",core=True)
    selfname=meta.TextField("个性签名",core=True,default='-')
    def __repr__(self):
        return self.username
    class META:
        admin = meta.Admin()


我在admin里,添加一条记录,
关于ImageField会出错:

TypeError at /admin/user/users/super852/ attribute name must be string Request
Method: POST  Request URL:
http://127.0.0.1:8000/admin/user/users/super852/  Exception
Type: TypeError  Exception Value: attribute name must be string  Exception
Location: c:\python24\lib\site-packages\django-
0.91-py2.4.egg\django\core\meta\__init__.py in method_save_file, line 1305


我把height_field=240,width_field=320,这两个参数去掉,就一切正常了...


请问这是怎么回事?应该怎么改? height_field和width_field到底怎么用?

既然要求是string，那就加个单引号试试

改成height_field='240',width_field='320',以后.提示如下错误.

google了一下，搜到这样一句话：
In the ImageField class, the width_field attribute should be holding
the *name* of the width field, not its value.

希望对你有用。
