当DEBUG = FALSE时，Django 500出错，但仅在某些页面上出现错误

我被困住了。当我设置DEBUG=False时，我收到500错误，但只有当我点击标签转到我index.html导航栏上的其他应用时。

这是我的settings.py：

这是我的index.html链接，它带我到错误页面：

<li><a class= 'navbar-link' href="{% url 'wallet:wallet_summary' %}">Wallet</a></li>

以下是urls.py中调用视图的模式：

urlpatterns=[
    url(r'^$',views.wallet_summary,name="wallet_summary"),
    url(r'^transfer/$',views.transfer,name='transfer'),
    url(r'^info/$',views.info,name='info'),
    url(r'^activity/$',views.RecentActivityView.as_view(),name='activity')

]

应呈现网页的views.py代码段：

def wallet_summary(request):
    return render(request,'wallet/wallet_summary.html',)

我要访问模板的目录树如下所示：

Tanta (BASE_DIR)
|
|
wallet
|
|--------->templates
|---------------------->wallet
|----------------------------------->wallet_summary.html

index.html页面渲染完全正常，但当我点击导航栏链接转到wallet_summary.html时，我收到500错误。

答案 0 :(得分：2)

我将此添加到我的settings.py文件中以将错误跟踪到控制台：

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'filters': {
        'require_debug_false': {
            '()': 'django.utils.log.RequireDebugFalse'
        }
    },

    'handlers': {
        'mail_admins': {
            'level': 'ERROR',
            'filters': ['require_debug_false'],
            'class': 'django.utils.log.AdminEmailHandler'
        },
     'console':{
            'level': 'DEBUG',
            'class': 'logging.StreamHandler',
        },
    },
    'loggers': {
        'django.request': {
            'handlers': ['console'],
            'level': 'ERROR',
            'propagate': True,
        },
    }
}

那告诉我，我有一个丢失的css文件，导致错误。我跑了python manage.py collectstatic并确保我所有的静态文件都是我告诉Django的地方。这样就可以渲染模板，现在可以使用了！
