Django - 'module'对象不可调用

Question

我尝试使用Django从数据库中提供图片，但是当我添加了

后，出现了一个HTML解析错误。

+ static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

当我访问urlpatterns时，出现了以下错误：TypeError at /: module object is not callable

这是追踪信息：

  27. ]+ static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

Exception Type: TypeError at /
Exception Value: 'module' object is not callable

我尝试在主urls.py和应用程序urls.py中使用它，但是没有生效。

我的media_root和media_urls如下：

abspath = lambda *p: os.path.abspath(os.path.join(*p))

PROJECT_ROOT = abspath(os.path.dirname(__file__))

MEDIA_ROOT = abspath(PROJECT_ROOT, 'media')
MEDIA_URL = '/media/'

我尝试了重新导入所有内容。

from django.conf.urls import *

但是它依然没有起作用。

编辑，这些是我的导入内容：

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

我正在使用最新版本的Django，并在Heroku上部署（本地使用heroku local）。

你需要展示在那个文件中你正在使用的导入。你是如何确切地导入“static”的？ - Daniel Roseman

Answer 1

改变

from django.conf.urls import static

到

from django.conf.urls.static import static

然后你就可以开始了。

Answer 2

from django.conf.urls.static import static

写下这行代码，而不是：

from django.conf.urls import static

你好，你可以使用代码块来格式化你的代码，使其更易读，使用反引号如下所示：from django.conf.urls.static import static - Yacine Mahdid
