장고 관리자를 사용하여 이미지를 업로드하는 동안 TemplateSyntaxError

나는 "Uploading images using Django Admin?"에서 예제를 시도했지만 불행히도 나는 항상 실패하고 있습니다.장고 관리자를 사용하여 이미지를 업로드하는 동안 TemplateSyntaxError

모델은 다음과 같습니다는

from django.db import models 
from django.contrib import admin 

class Celebrity(models.Model): 
    name = models.CharField(max_length=200) 

    def __unicode__(self): 
     return self.name 


class Image(models.Model): 
    celebrity = models.ForeignKey(Celebrity) 
    image = models.ImageField('Bild', upload_to="files/") 

    def __unicode__(self): 
     return self.image 

class InlineImage(admin.TabularInline): 
    model = Image 

class CelebrityAdmin(admin.ModelAdmin): 
    inlines = [InlineImage] 

admin.site.register(Celebrity, CelebrityAdmin)

MEDIA_ROOT은 다음과 같습니다

url(r'^media/(?P<path>.*)$', 'django.views.static.serve', 
{ 'document_root': 'c:/python/django/apps/af/neu/images/media/files' }), 

# Uncomment the next line to enable the admin: 
url(r'^admin/', include(admin.site.urls)),

이

MEDIA_ROOT = 'c:/python/django/apps/af/neu/images/media/'

는 URL입니다 이 구성 업로드가 작동하지만로 그때 나는 다음 역 추적 얻을 편집하려고 할 때 :

MEDIA_ROOT = os.path.join(os.path.dirname(file), "media").replace(r"\\", "//"),

또는

: 나는 또한 같은 MEDIA_ROOT을 시도

MEDIA_ROOT = os.path.join(os.path.dirname(file), "media").replace("\\", "//"),

하지만 업로드조차도 작동하지 않습니다.

그래서 저는 정말로 우둔합니다. 어떤 도움을 높이 평가합니다

그냥이 오류의 이유를 인용하고

class Image(models.Model): 
    celebrity = models.ForeignKey(Celebrity) 
    image = models.ImageField('Bild', upload_to="files/") 

    def __unicode__(self): 
     return self.image.name

당신도 reference.I에 대한 this 토론을 참조 이미지 클래스의 당신의 유니 코드 기능을 변경

def __unicode__(self): 
    return self.file.name

to achieve the same result.

훌륭한 작품입니다. Thanx so much – Helmut

행복하게 도와 줬습니다. :) – Konstant

추적은 당신에게 정확히 무슨 일이 일어나는지 알려줍니다. 오류는 클래스의 Image 클래스에 있습니다. image 속성을 반환하지만 문자열이 아니므로 유니 코드로 출력 할 수 없습니다.

image.url 대신 답장을 보내보세요.

The problem with this issue finally had nothing to do with the forms themselves, but the unicode method of the Image-model. Older implementations of ImageField had a unicode method of their own so

def __unicode__(self): 
    return self.file

worked fine. Now this needs to be
