'NoneType'對象沒有屬性'endswith'，django，python

Question

我的項目結構如下：

• / blog1 （項目名稱）
  • / blog1 /媒體/ blog1 /媒體
  • / blog （應用程序名稱）
    • /博客/媒體
    • /靜態的
    • /媒體
  • /靜態/模板

我已經通過django-admin面板上傳了一張照片，但是當我通過瀏覽器中的查看頁面源查看圖像時，它顯示錯誤：

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

追溯：

這是我在settings.py中的目錄：

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

這是我的模特：

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)

我的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'),
)   

和我的view_post.html：

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

我確信我在做一些愚蠢的錯誤，如果有人知道請幫助我。

在此先感謝，並抱歉目錄的命名錯誤，我是django的新手，不知道如何以正確的方式列出目錄。

Answer 1

我在settings.py添加了這個解決了類似的問題

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

也許你需要運行命令

python manage.py collectstatic

希望這可以幫助
