Ich versuche, ein benutzerdefiniertes Template-Tag zu erstellen, um einen Kommentar anzuzeigen. Wenn ich versuche, eine Antwort über das Formular zu jedem Kommentar zu senden, erhalte ich eine Fehlermeldung:Vorlagen-Tag funktioniert nicht mit csrf_token
Forbidden (403) CSRF-Überprüfung fehlgeschlagen. Anfrage abgebrochen. Grund für Fehler angegeben: CSRF-Token fehlt oder ist falsch.
Das csrf-Token funktioniert auf dem Formular mit der Download- und der Folgen-Schaltfläche, aber nicht mit dem Formular, das aus dem Vorlagen-Tag generiert wird. Jede Hilfe wäre willkommen.

Wenn ich das mache, bekomme ich diesen Fehler: Kontext muss ein Diktat sein, anstatt RequestContext. – user1637466
Versuchen Sie 't.render ({...}, request = context ['request'])' stattdessen. – Alasdair
Ja, die Dokumentation ist verwirrend; Die Template-Klasse, die Sie von get_template erhalten, ist nicht dieselbe, die Sie erhalten, wenn Sie eine Vorlage direkt instanziieren. –
