尝试在 Django 中运行服务器时出现系统检查错误

Question

我是django框架的新手尝试构建用于在文件系统中上传图像的模板并在页面上显示该图像。首先我得到错误首先我在文件

中得到错误

"/home/tac/Desktop/myproject/myapp/urls.py", line 5, in <module>
url(r'^$', 'list', name='list'),

文件“/usr/local/lib/python2.7/dist-packages/django/conf/urls/init.py”，第 85 行，在 url 提高类型错误（'view must be a callable or a list/tuple in the case of include().'）类型错误：在 include() 的情况下，视图必须是可调用的或 list/tuple。

我以某种方式解决了这个错误，但之后我遇到了另一个错误 enter image description here

myapp/urls.py

from django.conf.urls import include, url

urlpatterns = ('myapp.views',
    url(r'^$', list, name='list'),
    url(r'^list/$', list, name='list'),
)

myproject/urls.py

from django.conf.urls import include, url
from django.conf import settings
from django.conf.urls.static import static
from django.views.generic import RedirectView
from django.contrib import admin
# admin.autodiscover()

urlpatterns = [
        (r'^myapp/', include('myapp.urls')),
        (r'^$', 'myapp.views.index'),
        (r'^admin/', include(admin.site.urls)),
]
static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

错误线程启动的 nhandled 异常追溯（最近一次通话）：文件“/usr/local/lib/python2.7/dist-packages/django/utils/autoreload.py”，第 226 行，在包装器中 fn(*args, **kwargs) 文件“/usr/local/lib/python2.7/dist-packages/django/core/management/commands/runserver.py”，第 121 行，在 inner_run 中 self.check(display_num_errors=真) 文件“/usr/local/lib/python2.7/dist-packages/django/core/management/base.py”，第 420 行，检查中引发 SystemCheckError(msg) django.core.management.base.SystemCheckError：SystemCheckError：系统检查发现了一些问题：

错误： ?: (urls.E004) 您的 URL 模式 ('^$', 'myapp.views.index') 无效。确保 urlpatterns 是 url() 实例的列表。提示：尝试使用 url() 而不是元组。 ?: (urls.E004) 你的 URL 模式 ('^admin/', ([ , , , , \d+)/(?P.+)/$>, (None:None) ^auth/user/>, (None:None) ^auth/group/>, auth)/$>], 'admin', 'admin')) 无效。确保 urlpatterns 是 url() 实例的列表。提示：尝试使用 url() 而不是元组。 ?: (urls.E004) 您的 URL 模式 ('^myapp/', (, None, None)) 无效。确保 urlpatterns 是 url() 实例的列表。提示：尝试使用 url() 而不是元组。
