Django提交文件表单不会通过前端保存到模型

<form method="post" enctype="multipart/form-data">
    <!-- 表单字段 -->
</form>

from django import forms

class FileUploadForm(forms.Form):
    file = forms.FileField()  # 文件字段
    # 其他字段

from django.shortcuts import render, redirect
from .forms import FileUploadForm

def upload_file(request):
    if request.method == 'POST':
        form = FileUploadForm(request.POST, request.FILES)
        if form.is_valid():
            # 保存文件到模型或磁盘
            file = form.cleaned_data['file']
            # 执行文件处理逻辑
            # 模型保存示例：
            # YourModel.objects.create(file_field=file)
            return redirect('success')  # 重定向到成功页面
    else:
        form = FileUploadForm()
    return render(request, 'upload.html', {'form': form})

{% extends 'base.html' %}

{% block content %}
    <h1>文件上传</h1>
    <form method="post" enctype="multipart/form-data">
        {% csrf_token %}
        {{ form.as_p }}
        <button type="submit">提交</button>
    </form>
{% endblock %}
