save（）获得意外的关键字argumen

Question

调用LocationDescription.l\u edit返回错误“save（）获得意外的关键字参数”“location”“。”。关键字名称看起来是随机的，可能在不同的时间指向不同的字段。方法l\u edit被剥夺了功能，但错误仍然存在。奇怪的是，自我定位=kwargs[“位置”]后跟自我保存（）效果很好。在

在模型.py在

class LocationDescription(models.Model):
    location = models.ForeignKey(Location)
    description = models.ForeignKey(Localization)
    YEAR_CHOICES = (
        (LocationDescriptionYear.any.value, 'Any'),
        (LocationDescriptionYear.winter.value, 'Winter'),
        (LocationDescriptionYear.spring.value, 'Spring'),
        (LocationDescriptionYear.summer.value, 'Summer'),
        (LocationDescriptionYear.autumn.value, 'Autumn'),
    )
    year = models.IntegerField(choices=YEAR_CHOICES, default=0)
    DAY_CHOICES = (
        (LocationDescriptionDaytime.any.value, 'Any'),
        (LocationDescriptionDaytime.night.value, 'Night'),
        (LocationDescriptionDaytime.morning.value, 'Morning'),
        (LocationDescriptionDaytime.day.value, 'Day'),
        (LocationDescriptionDaytime.evening.value, 'Evening'),
    )
    day = models.IntegerField(choices=DAY_CHOICES, default=0)
    weather_type = models.ForeignKey('Weather', blank=True, null=True)
    order = models.IntegerField(default=0)
    code_check = models.TextField(blank=True, null=True)

    @classmethod
    def l_create(cls, request, **kwargs):
        l = Localization()
        l.write(request, kwargs['description'])
        kwargs['description'] = l
        item = cls(**kwargs)
        item.save()
        return item

    def l_delete(self):
        l = self.description
        self.delete()
        l.delete()

    def l_edit(self, **kwargs):
        super(LocationDescription, self).save(**kwargs)

    @classmethod
    def localize(cls, locale, **kwargs):
        if locale == 'eng':
            result = cls.objects.filter(**kwargs).annotate(text=F('description__eng'))
        elif locale == 'rus':
            result = cls.objects.filter(**kwargs).annotate(text=F('description__rus'))
        else:
            raise KeyError
        for r in result:
            if r.text is None or r.text == '':
                setattr(r, 'text', 'Error: localization text missing!')
        return result

save不需要您传递的那些命名参数。此外，由于您没有重写默认的save方法，所以我认为没有必要使用super。在

您只需在模型的那个实例上设置这些属性，然后用一个model对象调用save

def l_edit(self, **kwargs):
    for k in kwargs:
        setattr(self, k, kwargs[k])
    self.save()

另外，如果不需要在内存中使用item，那么使用^{}比当前的方法更有效。在
