MultiValueDictKeyError在Django管理

Question

UPDATE

型號：

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) 

管理：

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] 

當我在管理編輯車，我有錯誤：MultiValueDictKeyError在.. 「u'pictures-0-ID'」

Exception Type: MultiValueDictKeyError at /admin1/cars/car/1/ 
Exception Value: "u'pictures-0-id'" 

如何解決呢？我使用Django 1.6c1。

謝謝！

Answer 1

答：更新管理模板。

Answer 2

我認爲這是關係到一個Django 1.6票

#ticket 13696 -- ensured inline pk field is rendered

必須更新以下管理模板：

• stacked.html
• tabular.html

刪除一行：

個

{% if inline_admin_form.has_auto_field %}{{ inline_admin_form.pk_field.field }}{% endif %} 

，並添加行：

{% if inline_admin_form.needs_explicit_pk_field %} 
    {{ inline_admin_form.pk_field.field }} 
{% endif %} 

Answer 3

什麼固定對我來說是更新格拉佩利到2.5.1（假設你使用格拉佩利OFC）。我想這是因爲它執行特定的管理模板更新。

pip install django-grappelli==2.5.1 

Answer 4

Django的< = 1.7.3，也確保，你的內聯模式的主鍵字段是一個下拉列表AutoField：

錯誤：

class Car(models.Model): 
    id = IntegerField(primary_key=True) 

正確的：

class Car(models.Model): 
    id = AutoField(primary_key=True) 

見 https://code.djangoproject.com/ticket/15665

Answer 5

如果你已經在Django上的一個新版本，仍然可以得到這一點，請確保您的非下拉列表AutoField PK在模型定義「編輯=假」。
