Ok, here is part of the User Model:
class User(AbstractBaseUser, PermissionsMixin):
SEX = (
('m', 'male'),
('f', 'female')
)
RANG = (
('b', 'beginner'),
('e', 'expert'),
('m', 'master')
)
username = models.CharField(_('username'), max_length=30, unique=True,
help_text=_('Required. 30 characters or
fewer. Letters, numbers and @/./+/-/_ characters'),
validators=[
validators.RegexValidator(re.compile(
'^[\w.@+-]+$'), _('Enter a valid username.'), _('invalid'))
])
first_name = models.CharField(_('first name'), max_length=30, blank=True
, null=True)
last_name = models.CharField(_('last name'), max_length=30, blank=True,
null=True)
email = models.EmailField(_('email address'), max_length=255, unique=
True)
is_staff = models.BooleanField(_('staff status'), default=False,
help_text=_('Designates whether the user
can log into this admin site.'))
is_active = models.BooleanField(_('active'), default=True,
help_text=_('Designates whether this
user should be treated as active. Unselect this instead of deleting
accounts.'))
date_joined = models.DateTimeField(_('date joined'), default=timezone.
now)
expires = models.DateTimeField(_('expiration date'), default=
one_year_from_now)
age = models.IntegerField(blank=True, null=True)
sex = models.CharField(max_length=1, choices=SEX, blank=True)
native_language = models.CharField(max_length=200, blank=True)
english_proficiency = models.CharField(max_length=100, blank=True)
audio_device = models.CharField(max_length=200, blank=True)
autoplay_enabled = models.BooleanField(default=True)
USERNAME_FIELD = 'username'
REQUIRED_FIELDS = ['email', ]
objects = UserManager()
class Meta:
verbose_name = _('user')
verbose_name_plural = _('users')
def get_full_name(self):
full_name = '%s %s' % (self.first_name, self.last_name)
return full_name.strip()
def get_short_name(self):
return self.first_name
"""
def is_active(self):
return timezone.now() <= self.expires
"""
def email_user(self, subject, message, from_email=None):
send_mail(subject, message, from_email, [self.email])
(I removed some unrelated fields).
Now what I did was add the autoplay_enabled feature yesterday which wasn't
there before. After adding this field, I saved the models.py ran manage.py
makemigrations (no changes detected) and then still tried to run manage.py
migrate.
After starting the server when I tried to log into the Admin panel with the
Admin user (the DB was already populated by the Admin user, two more users
and other stuff) it gave me an OperationalError: column autoplay_enabled
does not exist.
This happened to me a lot of times when I added new fields to any of the
models. I ended up writing a script that pre-populates the DB for me but I
still have to manually delete my sqlite file, run migrations or syncdb and
then create the superuser again.
So what am I doing wrong? I'm sure it's just my fault. At first I even
manually edited the migrations file in the past, for example when I changed
one of the fields to be mandatory instead of being optional. Old data in
the database had this field still set to null, and sometimes Django asked
me what to do with it but most of the time I never got it to work correctly
- so again delete DB and repeat.
