Ich verwende django-stdimage zum Hochladen und Ändern der Größe von Bildern, und es funktioniert gut.
Ich habe jedoch ein Problem mit Django-Allauth; wenn ich versuche, mit dem sozialen Konto anmelden, und es gibt bereits ein normales Konto mit derselben E-Mail-Adresse, erhalte ich folgende Fehlermeldung:<StdImageFieldFile: None> ist nicht JSON serializable
TypeError at /accounts/facebook/login/callback/
is not JSON serializable
Dies ist die vollständige Rückverfolgung:

Ich kann nicht verstehen, ob es ein Django-Allauth-Problem oder etwas anderes ist.
Dies ist models.py:
class CustomUser(AbstractBaseUser, PermissionsMixin):
first_name = models.CharField(max_length=254, blank=True)
second_name = models.CharField(max_length=254, blank=True)
email = models.EmailField(blank=True, unique=True)
date_joined = models.DateTimeField(_('date joined'), default=datetime.now())
#avatar = models.ImageField('profile picture', upload_to=upload_avatar_to, null=True, blank=True)
avatar = StdImageField(upload_to=upload_avatar_to, null=True, blank=True,
variations={
'thumbnail': {'width': 250, 'height': 250, "crop": True}
})
is_active = models.BooleanField(default=False)
is_admin = models.BooleanField(default=False)
is_staff = models.BooleanField(default=False)
USERNAME_FIELD = 'email'
REQUIRED_FIELDS = ['first_name', 'second_name']
objects = CustomUserManager()
class Meta:
verbose_name = _('user')
verbose_name_plural = _('users')
def save(self, *args, **kwargs):
super(CustomUser, self).save(*args, **kwargs)
def get_absolute_url(self):
return "https://stackoverflow.com/users/%s" % urlquote(self.email)
def get_full_name(self):
"""

return self.email
def __str__(self):

"""
return self.first_name
def email_user(self, subject, message, from_email=None):

send_email(subject, message, from_email, [self.email])
ich auch django-stdimage-serializer zu verwenden, habe es versucht, aber wenn ich versuche, die Modelle mit ihm Datei einzurichten, und makemigrations Feuer, das ist, was ich bekommen:

Was könnte ich tun?
