无法在简单的django网站上显示图像

Question

我有一个非常简单的django网站,但我无法获取我在管理面板中显示的图像.

我settings.py有这些常数:

# Absolute path to the directory that holds media.
# Example: "/home/media/media.lawrence.com/"
MEDIA_ROOT = '/home/jeroen/programming/python/django/sitename/media'

# URL that handles the media served from MEDIA_ROOT. Make sure to use a
# trailing slash if there is a path component (optional in other cases).
# Examples: "http://media.lawrence.com", "http://example.com/media/"
MEDIA_URL = 'http://127.0.0.1:8000/media/'

# URL prefix for admin media -- CSS, JavaScript and images. Make sure to use a
# trailing slash.
# Examples: "http://foo.com/media/", "/media/".
ADMIN_MEDIA_PREFIX = '/media/'

我urls.py看起来像这样:

from django.conf.urls.defaults import *
from django.conf import settings

# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    # Example:
    # (r'^sitename/', include('sitename.foo.urls')),

    # Uncomment the admin/doc line below and add 'django.contrib.admindocs' 
    # to INSTALLED_APPS to enable admin documentation:
    (r'^admin/doc/', include('django.contrib.admindocs.urls')),

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

    # http://docs.djangoproject.com/en/dev/howto/static-files/
    # This method is inefficient and insecure. 
    # Do not use this in a production setting. 
    # Use this only for development.
    (r'^media/(?P<path>.*)$', 'django.views.static.serve',
        {'document_root': settings.MEDIA_ROOT}),
)

我models.py看起来像这样:

from django.db import models

class Truitje(models.Model):
    titel = models.CharField(max_length=50)
    beschrijving = models.TextField(max_length=500)
    foto = models.ImageField(upload_to='truitjes')

    def __unicode__(self):
      return self.titel

我可以在管理界面中成功上传图片并将其存储起来/home/jeroen/programming/python/django/sitename/media/truitjes.但是当我举个例子时,http://127.0.0.1:8000/media/truitjes/DSC00068.JPG我得到一个错误:Page not found: /media/truitjes/DSC00068.JPG.同样的http://127.0.0.1:8000/media/truitjes,和`` http://127.0.0.1:8000/media/gives权限被拒绝:/ media /`.

Answer 1

将您的媒体或管理URL /前缀更改为其他内容.

它们不能具有相同的值.如果他们这样做,ADMIN_MEDIA_PREFIX则优先.这意味着如果您尝试访问http://127.0.0.1:8000/media,则尝试访问管理媒体文件夹.

要么改变ADMIN_MEDIA_PREFIX:

ADMIN_MEDIA_PREFIX = '/admin-media/'

或改变MEDIA_ROOT:

# in settings.py

MEDIA_ROOT = '/home/jeroen/programming/python/django/ninikske/static'
MEDIA_URL = 'http://127.0.0.1:8000/static/'

# and in url.conf

(r'^static/(?P<path>.*)$', 'django.views.static.serve',
 {'document_root': settings.MEDIA_ROOT}),

在Django 1.3中,如果您只是想在开发过程中尝试在视图中显示图像,请按照以下步骤操作:

1. 在应用程序的目录中创建一个名为"static"的文件夹
2. 将图像放在静态文件夹中
3. 确保settings.py中的STATIC_URL设置为'/ static /' - 这应该是默认值

4. 在你的app/urls.py中:

   from django.contrib.staticfiles.urls import staticfiles_urlpatterns
   #..rest of url.py config...
   urlpatterns += staticfiles_urlpatterns()
   

5. 在您的模板中,无论您希望图片显示在哪里,都可以使用此模板标记:

   <img src="{{ STATIC_URL }}pic.png" />
