如何在页面重载后将文件保留在表单集中？姜戈

# forms.py
from django import forms

class FileUploadForm(forms.Form):
    file = forms.FileField()

# views.py
from django.shortcuts import render
from .forms import FileUploadForm

def upload_file(request):
    if request.method == 'POST':
        form = FileUploadForm(request.POST, request.FILES)
        if form.is_valid():
            file = form.cleaned_data['file']
            # 处理文件保存逻辑
            # ...

            return render(request, 'success.html')
    else:
        form = FileUploadForm()

    return render(request, 'upload.html', {'form': form})

# upload.html
<form method="post" enctype="multipart/form-data">
    {% csrf_token %}
    {{ form.file }}
    <input type="submit" value="Upload">
</form>

# success.html
<p>File uploaded successfully!</p>
