标签: python django django-file-upload

我正在Django制作简单的博客网站,我收到了这个错误:invalid literal for int() with base 10: 'media'。当我在我的博客应用程序中将modelsField添加到models.py时,它很高兴。这是一些代码:

models.py

from django.db import models
from django.contrib.auth.models import User
from django.utils import timezone


class Post(models.Model):

    STATUS_CHOICES = (
        ('draft', 'Roboczy'),
        ('publish', 'Publiczny')
    )

    author = models.ForeignKey(User)
    title = models.CharField(max_length=140)
    slug = models.SlugField(max_length=140)
    image = models.FileField(blank=False, null=False, upload_to='media_cdn')
    body = models.TextField()
    publish = models.DateTimeField(default=timezone.now)
    created = models.DateTimeField(auto_now_add=True)
    updated = models.DateTimeField(auto_now=True)
    status = models.CharField(max_length=10, choices=STATUS_CHOICES, default='draft')

    class Meta:
        ordering = ['-publish']

    def __str__(self):
        return self.title

以下是settings.py的一部分:

STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, "staticfiles")

MEDIA_URL = "/media/"
MEDIA_ROOT = os.path.join(os.path.dirname(BASE_DIR), "media_cdn")

和urls.py

from django.conf import settings
from django.conf.urls import url, include
from django.conf.urls.static import static
from django.contrib import admin

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^', include('blog.urls'))
]

if settings.DEBUG:
    urlpatterns += static(settings.MEDIA_URL,
                          document_root=settings.MEDIA_ROOT)
    urlpatterns += static(settings.STATIC_URL,
                          document_root=settings.STATIC_ROOT)

非常感谢您的帮助!

博客/ urls.py

from django.contrib.auth.urls import url
from .views import PostList, PostDetail

urlpatterns = [
    url(r'^$', PostList.as_view(), name='blog'),
    url(r'(?P<pk>[^/]+)', PostDetail.as_view(), name='post'),

        PostDetail.as_view(), name='post_detail'),
]

答案 0 :(得分:2)

这些模式正在消耗对媒体文件的所有请求。

url(r'^', include('blog.urls'))  # in main urls.py

url(r'(?P<pk>[^/]+)', PostDetail.as_view(), name='post')  # in blogs/urls.py

当您转到http://127.0.0.1:8000/media/media_cdn/e1980c9642c03529db70a9c6060f247f.jpg时,网址路由器会尝试将其用于博客条目,从而导致此错误。

您应该重写您的网址模式,以便不会发生这种情况。如果您的博客网址仅使用数字网址(例如http://127.0.0.1:8000/1/),则可以为此创建模式。

url(r'^(?P<pk>\d+)/$', PostDetail.as_view(), name='post'),
url(r'^(?P<pk>\d+)/(?P<slug>[-\w]+)/$', PostDetail.as_view(), name='post_detail'),

请记住在您的网址格式中使用^$。 有关url模式和调度如何工作的更多示例和说明,请参阅官方文档。 Hadoop Pig - Removing csv header
