Как решить такую ошибку в джанго?

Question

[Vlad242]

Что нужно поменять в коде ?

from django.db.models.signals import post_save
from django.contrib.auth.models import User
from django.dispatch import receiver
from .models import Profile


@receiver(post_save, sender=User)
def create_profile(sender, instance, created, **kwargs):
    if created:
        Profile.objects.create(user=instance)
        


@receiver(post_save, sender=User)
def save_profile(sender, instance, **kwargs):
    instance.profile.save()

Вот ошибка TypeError: save() got an unexpected keyword argument 'force_insert'

Где модели? На какой строчке ошибка?

[Vlad242]

Roman Kitaev, def save_profile(sender, instance, **kwargs):
instance.profile.save()
вот тут ошибка

Vlad242,

Где модели?

Vlad242, полный текст ошибки добавьте в вопрос.

[Vlad242]

Roman Kitaev, отправил сверху

[Сергей Горностаев]

Vlad242, у вас метод save случаем не переопределён в Profile или User?

[Vlad242]

Сергей Горностаев, вроде нет

from django.db import models
from django.contrib.auth.models import User
from PIL import Image


class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    image = models.ImageField(default='default.jpg', upload_to='profile_pics')

    def __str__(self):
        return f'{self.user.username} Profile'

    def save(self):
        super().save()

        img = Image.open(self.image.path)

        if img.height > 300 or img.width > 300:
            output_size = (300, 300)
            img.thumbnail(output_size)
            img.save(self.image.path)

[Roman K]

Vlad242,

вроде нет

def save(self):
super().save()

Ну понятненько. Может, пойдёшь поучишь питон?

[Сергей Горностаев]

Вы теряете аргументы метода save. Исправьте так:

class Profile(models.Model):
    ...
    def save(self, *args, **kwargs):
        super().save(*args, **kwargs)
        ...

А ещё лучше вообще не переопределяйте его и переложите задачу ресайзинга аватарки на обработчик сигнала save_profile

Вот так?)

def save(self, *args, **kwargs):
        super().save(*args, **kwargs)
        if created:
        Profile.objects.create(user=instance)

[Сергей Горностаев]

Vlad242, нет. Дополнил ответ.

[Vlad242]

Сергей Горностаев, спасибо
