如何在django的媒体文件夹中创建和保存csv文件？

MEDIA_ROOT = os.path.join(BASE_DIR, 'media')

import csv
import os
from django.conf import settings

def save_csv_file(request):
    if request.method == 'POST' and request.FILES['csv_file']:
        csv_file = request.FILES['csv_file']
        file_path = os.path.join(settings.MEDIA_ROOT, csv_file.name)
        
        with open(file_path, 'wb') as file:
            for chunk in csv_file.chunks():
                file.write(chunk)
        
        return 'CSV文件已保存'

from django.urls import path
from .views import save_csv_file

urlpatterns = [
    path('save-csv/', save_csv_file, name='save_csv'),
]
