Django Reverse Match Probleme

Question

Ich habe versucht herauszufinden, warum ich Probleme damit habe. Alles scheint in Ordnung zu sein, und ich habe keine Probleme damit, dass andere Urls umkehren. Wenn ich die URL manuell eingebe, kommt die Seite gut an.

Dies ist der Template-Tag, das die Probleme verursacht: {% url 'schedule:calendar' %}

Hier ist urls.py:

app_name = 'schedule' 
urlpatterns = [ 
    url(r'^$', login_required(views.CalendarView.as_view(), login_url='/login/'), name='calendar'), 
] 

Ich glaube nicht, es ist notwendig, aber meine Ansichten Datei hat dies nur darin:

class CalendarView(TemplateView): 
    template_name = 'schedule/index.html' 

    def get_context_data(self, **kwargs): 
     context = super(CalendarView, self).get_context_data(**kwargs) 
     context['template'] = 'calendar_view' 
     return context 

ich sehe nicht, Konflikte überhaupt zu nennen, aber wenn ich {% url 'schedule:calendar' %} in meiner Vorlage setzen, überall, wirft er den Fehler, auch wenn das der onl ist y was in der Vorlagenseite. Hier

ist der Fehler:

Can you post your debug information for patterns' order (just hit the wrong url and Django will display in "debug on" it for you) ? – Artem Bernatskyi

Dank Artem Bernatskyi Kommentar, ich es herausgefunden. Ich habe eine API für die Daten, und ich hatte einen Namensraumkonflikt in der Datei urls.py für diese API. Es hatte app_name='schedule' drin. Ich habe es umbenannt und alles funktioniert jetzt gut.

Für alle, die das gleiche Problem haben, könnte es am schnellsten sein, wenn Sie nur Ihren gesamten Code nach den Namen durchsuchen, die Sie umkehren möchten. Stellen Sie sicher, dass sie nicht in einer anderen urls.py-Datei erscheinen.

Danke Artem.
