Question

我正在尝试在EC2 ubuntu实例上设置django。

在我看来，我有：

from django.shortcuts import render, HttpResponse
import requests


def test(request):
    return HttpResponse('hi')

urls.py：

urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'tp.views.home', name='home'),
    # url(r'^blog/', include('blog.urls')),
    url(r'^index/$', 'tp1.views.index', name='index'),
    url(r'^test/$', 'tp1.views.test', name='test'),    

    # url(r'^admin/', include(admin.site.urls)),
)

我收到上面的错误。我做错了什么？

编辑;

Answer 1

您问题中的代码看起来不错，但test()视图函数需要一个位置参数（request），因此您问题中的代码不是代码提出了这个例外。

您是否遗漏了任何代码（可能您稍后在test文件中重新定义views.py）？该代码位于tp1/views.py或其他文件的顶部吗？

Answer 2

在此代码中：

 urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'tp.views.home', name='home'),
    # url(r'^blog/', include('blog.urls')),
    url(r'^index/$', 'tp1.views.index', name='index'),
    url(r'^test/$', 'tp1.views.test', name='test'),    

    # url(r'^admin/', include(admin.site.urls)),
)

将方括号更改为方括号：

urlpatterns = patterns['',
    # Examples:
    # url(r'^$', 'tp.views.home', name='home'),
    # url(r'^blog/', include('blog.urls')),
    url(r'^index/$', 'tp1.views.index', name='index'),
    url(r'^test/$', 'tp1.views.test', name='test'),    

    # url(r'^admin/', include(admin.site.urls)),
]

Django错误：取0位置参数但给出1
