Question

我收到此错误“'NoneType'对象没有属性'slug'”

在create_path的第48行中：return 'uploads/{0}/{1}'.format(instance.game.slug, filename)

model.py

def create_path(instance, filename):
    return 'uploads/{0}/{1}'.format(instance.game.slug, filename)



class OnlineGame(models.Model):
    name=models.CharField(max_length=120)
    slug=models.CharField(max_length=25,unique=True)
    icon=models.ImageField(upload_to='uploads/onlinegame',blank=True,null=True)


class Player(models.Model):
    slug=models.SlugField(unique=True,max_length=120)
    fullname=models.CharField(max_length=120,null=True,blank=True)  
game=models.ForeignKey(OnlineGame,null=True,blank=True,related_name='playergame',on_delete=models.PROTECT)

Answer 1

我忘记将slug=models.CharField(max_length=25,unique=True)更改为slug=models.SlugField(max_length=25,unique=True)

现在可以了。

'NoneType'对象没有属性'slug'
