Here are my directories in settings.py :

这是我在设置中的目录。py:

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

Here are my models :

以下是我的模型:

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 })

Here is my views.py:

这是我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)

    })

My admin.py:

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)

my urls.py:

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'),
)

and my view_post.html:

和我view_post.html:

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

I am sure i am doing some silly mistake , if anyone knows please help me .

我确信我犯了一个愚蠢的错误，如果有人知道请帮助我。

Thanks in advance, and sorry for bad naming of directories , i am new to django and don't know how to list directories in right way.

预先感谢，抱歉对目录命名不好，我是django的新手，不知道如何以正确的方式列出目录。

I solved similar problem by add this in settings.py

我通过在settings.py中添加这个来解决类似的问题

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

and also maybe you need to run command

也许你还需要运行命令

python manage.py collectstatic

Hope this helps
