Peewee model_form nicht aktualisieren

Question

Ich verwende Peewee model_form, um eine Instanz eines Eintrags in meiner Datenbank zu aktualisieren. Im Folgenden finden Sie meinen Code für das Formular, die Vorlage und die App. Aus irgendeinem Grund glaube ich nicht, dass ich eine POST bekomme, wenn ich das Formular abschicke, aber ich schreibe meinen Code auf die gleiche Weise, wie ich es in der Vergangenheit ohne irgendwelche Probleme getan habe. Jede Hilfe wäre willkommen!

Es ist wie Sie sucht nach bekam eine Aktion Form hinzuzufügen:

<form action="" method="POST" class="form"> 

Versuch:

<form action="{{ url_for('edit_entry') }}" method="POST" class="form">
