所有位置的NoReverseMatch，Django 1.9

问题描述 投票：1回答：1

因此，我正在和朋友一起使用Django 1.9在Django中创建一个Web应用程序。然而，最近我从我们的git repo中删除了一些小的改动，突然间我得到NoReverseMatch，无论我在哪里尝试进入我们的页面。它适用于我的朋友，我们正在使用相同版本的Django。

所做的更改是在forms.py和views.py中，在urls.py中没有触及任何内容，我收集了这个问题的最常见原因来自。

我们有两个urls.py文件，一个在我们的app目录中：

(imports and fluff omitted)
urlpatterns = [
url(r'^', views.index, name = 'index'),
url(r'^play', views.play, name='play'),
url(r'^create_user/$', views.create_user, name='create_user'),
]

和app dir上面的目录中的一个：

(imports and fluff omitted again)
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'', include('antonymapp.urls')),
url(r'^accounts/login/$', login),
]

无论URL定义在何处，问题仍然存在。

这是我们的views.py文件，省略了导入：

def index(request):
    return render(request, 'antonymapp/index.html', {})


def login(request):
    return render(request, 'antonymapp/login.html', {})

def create_user(request):
    if request.method == "POST":
    form = UserCreationForm(request.POST)
    if form.is_valid():
        username = form.cleaned_data["username"]
        password = form.cleaned_data["password1"]
        new_user = User.objects.create_user(username=username, password=password)
        return redirect('play')
else:
    form = UserCreationForm()

return render(request, 'antonymapp/create_user.html', {'form': form}) 

@login_required
@csrf_protect
def play(request):
    if request.method == 'POST':
        form = SomeForm(request.POST)
        print(form.is_valid()) 
        if form.is_valid():
            picked = form.cleaned_data.get('picked')
            picked = int(picked[0])
            player = request.user.userprofile
            player.score = player.score + picked
            player.save()
    else:
        form = SomeForm

    return render(request, 'antonymapp/play.html', {'form':form })

来自django导入表单的forms.py

class SomeForm(forms.Form):
    CHOICES = ((1,'1'),
               (2,'2'),
               (3,'3'),
               (4,'4'),
               (5,'5'),)
    picked = forms.ChoiceField(choices=CHOICES, widget=forms.RadioSelect())

我和我的朋友坐在不同的计算机上，我们都修复了一个错误（以同样的方式）他将更改推送到github。然后我删除了我所做的更改并删除了他的更改（我们还没有学习如何在github中处理分支）。

所以我不确定我是否能找到差异，因为在删除我的更改并删除更改之前，我从未提交过我的文件。

编辑

我最终做的是删除我的本地版本的项目，然后从git克隆。它现在有效，但我不知道为什么和出了什么问题。

只是为了添加到语料库，我也发生了这种情况。这是一个非常基本的项目，没有任何有趣的事情发生。

所有我改变的是安装psycopg2和一个正在工作的项目停止工作与上述相同的错误。

虽然我没有删除我卸载的项目，而是在环境中重新安装了django，但突然间网址再次正常运行。

Ubuntu 18.04
Django 2.1.1

是的，奇怪的错误。
