Question

我是django框架中的新手尝试为文件系统中的上传图像构建模板，并在页面上显示此图像。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，在网址中引发TypeError（'视图必须是可调用的，或者在include（）的情况下是list / tuple。'） TypeError：在include（）。

的情况下，view必须是可调用的或list / tuple

不知何故，我解决了这个错误，但在那之后，我面临另一个错误 enter image description here

的myapp / urls.py

from django.conf.urls import include, url

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

的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)

错误开始的线程中的nhandled异常 Traceback（最近一次调用最后一次）：文件“/usr/local/lib/python2.7/dist-packages/django/utils/autoreload.py”，第226行，在包装器中 fn（* args，** kwargs）在inner_run中输入文件“/usr/local/lib/python2.7/dist-packages/django/core/management/commands/runserver.py”，第121行 self.check（display_num_errors =真）文件“/usr/local/lib/python2.7/dist-packages/django/core/management/base.py”，第420行，正在检查中提升SystemCheckError（msg） django.core.management.base.SystemCheckError：SystemCheckError：系统检查发现了一些问题：
