推荐答案

首先，您需要添加 enctype =multipart / form-data / code>在您的< form> 定义。因为这是文件上传所需的。

First, you will need to add enctype="multipart/form-data" in your <form> definition. As this is required for file uploads.

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

第二，而不是 form_class（request.POST）您将需要通过传递 request.FILES 在您的视图中创建表单。

Second, instead of form_class(request.POST) you will need to create form in your view by passing request.FILES too.

form_class(request.POST, request.FILES)
