Answer 1

Zuerst müssen Sie enctype="multipart/form-data" in Ihre <form> Definition hinzufügen. Dies ist für das Hochladen von Dateien erforderlich.

<form role="form" action="" method="post" enctype="multipart/form-data"> 

Zweitens statt form_class(request.POST) müssen Sie, indem request.FILES zu bilden in Ihrer Ansicht erstellen.

form_class(request.POST, request.FILES)
