'NoneType' 對象有沒有屬性 '的endsWith'，Django的，蟒蛇

Question

我的項目結構是這樣的：

• /blog1 （項目名稱）
  • /blog1 /媒體/ blog1 /媒體
  • /博客（應用名稱）
    • /博客/媒體
    • /靜態
    • /媒體
  • /靜態/模板

我已經上傳通過Django的管理面板中的照片，但是當我查看圖片通過瀏覽器的查看頁面源顯示錯誤：

AttributeError at /blog/view/blog1/media/high-tech-snapshot_3.jpg 
'NoneType' object has no attribute 'endswith'

這裏是我的目錄settings.py中：

STATIC_URL = '/static/' 
MEDIA_URL = '/media/blog1/media/' 
MEDIA_ROOT = os.path.join(os.path.dirname(__file__), 'media') 

這裏是我的模型：

from django.db import models 
from django.db.models import permalink 
from embed_video.fields import EmbedVideoField 

class Blog(models.Model): 
    title = models.CharField(max_length=100, unique=True) 
    slug = models.SlugField(max_length=100, unique=True) 
    body = models.TextField() 
    posted = models.DateTimeField(db_index=True, auto_now_add=True) 
    category = models.ForeignKey('blog.Category') 
    video = EmbedVideoField(blank=True) 
    photo = models.ImageField(upload_to="blog1/media/", blank=True) 

    def __unicode__(self): 
     return '%s' % self.title 

    @permalink 
    def get_absolute_url(self): 
     return ('view_blog_post', None, { 'slug': self.slug }) 

這裏是我的views.py：

def index(request): 
    return render_to_response('index.html', { 
     'categories': Category.objects.all(), 
     'posts': Blog.objects.all()[:6] 
     }) 

def view_post(request, slug): 
    return render_to_response('view_post.html', { 
     'post': get_object_or_404(Blog, slug=slug) 

    }) 

我的admin.py：

from django.contrib import admin 
from blog.models import Blog 
from embed_video.admin import AdminVideoMixin 

class BlogAdmin(admin.ModelAdmin): 
    exclude = ['posted'] 
    prepopulated_fields = {'slug': ('title',)} 

    admin.site.register(Blog, BlogAdmin) 

我urls.py：

from django.conf.urls import patterns, include, url 
import os 
from django.contrib import admin 
admin.autodiscover() 

urlpatterns = patterns('', 
# Examples: 
# url(r'^$', 'blog1.views.home', name='home'), 
# url(r'^blog/', include('blog.urls')), 
url(r'^admin/', include(admin.site.urls)), 

url(r'^$', 'blog.views.index'), 

url(
r'^blog/view/(?P<slug>[^\.]+).html', 
'blog.views.view_post', 
name='view_blog_post'), 

url(r'^About/$', 'blog.views.about', name='about'), 

url(
r'^blog/category/(?P<slug>[^\.]+).html', 
'blog.views.view_category', 
name='view_blog_category'), 


url(r'^blog/view/blog1/media/(.*)$', 'django.views.static.serve',name ='media_url'), 
) 

和我view_post.html：

{% block content %} 
<h2>{{ post.title }}</h2> 
<p>{{ post.body }}</p> 
<img src="{{ post.photo }}"/> 
{% endblock %} 

我相信我做了一些愚蠢的錯誤，如果有誰知道，請幫助我。

在此先感謝，並且對於錯誤的目錄命名感到抱歉，我是django的新手，不知道如何以正確的方式列出目錄。

我解決了類似的問題，這個在settings.py

BASE_DIR = os.path.dirname(os.path.dirname(__file__)) 
STATIC_ROOT = os.path.join(BASE_DIR, 'static') 

增加，也或許你需要運行命令

python manage.py collectstatic 

希望這有助於
