我正在尝试创建一个用于我的旧用户表的自定义用户模型。密码字段名为user_password。我尝试覆盖AbstractBaseUser的password字段并添加db_column='user_password，
[field for field in MyUser._meta.fields if field.name == "password"][0].db_column = "user_password"
在末尾。这是我的模特：
class MyUser(AbstractBaseUser, PermissionsMixin):
user_id = models.IntegerField(primary_key=True)
is_active = models.BooleanField(_('active'), default=True, db_column='user_active',
help_text=_('Designates whether this user should be treated as '
'active. Unselect this instead of deleting accounts.'))
username = models.CharField(max_length=25, unique=True)
# user_password = models.CharField(max_length=128, verbose_name='password', db_column=b'user_password')
user_session_time = models.IntegerField(default=0)
user_session_page = models.IntegerField(default=0)
user_lastvisit = models.IntegerField(default=0)
user_regdate = models.IntegerField(default=0)
user_level = models.IntegerField(blank=True, null=True)
user_posts = models.IntegerField(default=0)
user_timezone = models.DecimalField(max_digits=5, decimal_places=2, default=0.00)
user_style = models.IntegerField(blank=True, null=True)
user_lang = models.CharField(max_length=255, blank=True)
user_dateformat = models.CharField(max_length=14, default='d M Y H:i')
user_new_privmsg = models.IntegerField(default=0)
user_unread_privmsg = models.IntegerField(default=0)
user_last_privmsg = models.IntegerField(default=0)
user_emailtime = models.IntegerField(blank=True, null=True)

user_allowavatar = models.BooleanField(default=True)
user_allow_pm = models.BooleanField(default=True)
user_allow_viewonline = models.BooleanField(default=True)
user_notify = models.BooleanField(default=False)
user_notify_pm = models.BooleanField(default=True)
user_popup_pm = models.BooleanField(default=False)
user_rank = models.IntegerField(blank=True, null=True)
user_avatar = models.CharField(max_length=100, blank=True)
user_avatar_type = models.IntegerField(default=0)
email = models.EmailField(max_length=255, blank=True, db_column='user_email')
user_icq = models.CharField(max_length=15, blank=True)
user_website = models.CharField(max_length=100, blank=True)
user_from = models.CharField(max_length=100, blank=True)
user_sig = models.TextField(blank=True)
user_sig_bbcode_uid = models.CharField(max_length=10, blank=True)
user_aim = models.CharField(max_length=255, blank=True)
user_yim = models.CharField(max_length=255, blank=True)
user_msnm = models.CharField(max_length=255, blank=True)
user_occ = models.CharField(max_length=100, blank=True)
user_interests = models.CharField(max_length=255, blank=True)
user_actkey = models.CharField(max_length=32, blank=True)
user_newpasswd = models.CharField(max_length=32, blank=True)
first_name = models.CharField(_('first name'), max_length=30, blank=True)
last_name = models.CharField(_('last name'), max_length=30, blank=True)
is_staff = models.BooleanField(_('staff status'), default=False,
help_text=_('Designates whether the user can log into this admin '
'site.'))
date_joined = models.DateTimeField(_('date joined'), default=timezone.now) #regdate
class Meta:
managed = True
db_table = 'phpbb_users'
verbose_name = 'User'
verbose_name_plural = 'Users'
objects = UserManager()
USERNAME_FIELD = 'username'
REQUIRED_FIELDS = ['email']
def get_full_name(self):
return '%s, %s' % (self.username, self.user_email)
def get_short_name(self):
return self.username
def __str__(self):
return self.username
以下之后，
[field for field in MyUser._meta.fields if field.name == "password"][0].db_column = "user_password"
我无法createasuperuser甚至只能runserver。我得到以下stacktrace：

为什么它无法识别数据库中的user_password列？ Makemigration检测到{My}的db_column更改并显示在0001_initial.py。
答案 0 :(得分：0)
[field for field in AbstractBaseUser._meta.fields if field.name == "password"][0].db_column = "user_password"
在课前，似乎解决了这个问题。
