python - django 模板不存在

Question

我想做一个注册页面，当用户点击注册时，它会检查两个密码是否相同，如果不相同，在“确认密码”后给出错误信息。

但是当我在 views.py 中调用“return render(request, reverse("accounts:signup"), {'form': signup_form}) ”时，它显示错误，回溯是:

Environment:

Request Method: POST
Request URL: http://127.0.0.1:8000/accounts/signup_post/

Django Version: 1.7

Template Loader Error:
Django tried loading these templates, in this order:

我的帐户应用程序如下所示:

urls.py:

urlpatterns = patterns(

账户/urls.py:

urlpatterns = patterns(

    url(r'^login_post/$', views.login_post, name='login_post'),
    url(r'^signup_post/$', views.signup_post, name='signup_post'),

views.py 中的 signup_post 函数:

def signup_post(request):
    if request.method == 'POST':
        signup_form = forms.SignupForm(request.POST)

        if signup_form.is_valid():
            signup_info = signup_form.cleaned_data
            username = signup_info['username']
            email = signup_info['email']
            password = signup_info['password_1']
            user = User.objects.create_user(
                username=username,
                email=email,
                password=password)
            user.save()

    else:
        signup_form = forms.SignupForm()

    return render(request, reverse("accounts:signup"), {'form': signup_form})

我已阅读 Django TemplateDoesNotExist和其他类似的问题，但没有帮助!

ps:我问过another question关于注册，也许有用。

这里的问题是

reverse("accounts:signup")

返回一个 url，见这里(https://docs.djangoproject.com/en/1.7/ref/urlresolvers/#reverse)，而你需要一个模板路径，所以你应该返回:

return render(request, 'accounts/signup.html', {'form': signup_form})
