Django管理中的MultiValueDictKeyError [英] MultiValueDictKeyError in Django admin

问题描述

更新

型号：

class PicturesManager(models.Manager):
    def create_pictures(self, flat, img):
        pictures = self.create(car=car, image=img)
        return pictures

def get_file_path(instance, filename):
    filename = "%s.%s" % (uuid.uuid4(), filename.split('.')[-1])
    return os.path.join('car_img/', filename)

class Pictures(models.Model):
    car = models.ForeignKey(Car, verbose_name="Car Image", related_name='pictures')
    image = models.ImageField(verbose_name="Photo", upload_to = get_file_path, max_length=64)
    objects = PicturesManager()
    def __unicode__(self):
        return str(self.id)

admin： / p>

admin:

class MyInlineModelAdmin(admin.TabularInline):
    model = Pictures
    extra = 3
class CarOptionsInline(admin.StackedInline):
    model = CarOptions

class WatchesInline(admin.StackedInline):
    model = Watches

class CarAdmin(admin.ModelAdmin):
    inlines = [CarOptionsInline, WatchesInline, MyInlineModelAdmin]

当我在管理员中编辑Car时，我有错误： MultiValueDictKeyError at ...u'pictures-0-id'

When I edit Car in admin, I have error: MultiValueDictKeyError at ... "u'pictures-0-id'"
