如何从多个django模型导出数据到csv文件？

import csv
from django.http import HttpResponse

def export_to_csv(request):
    response = HttpResponse(content_type='text/csv')
    response['Content-Disposition'] = 'attachment; filename="data.csv"'

    writer = csv.writer(response)
    
    # 导出模型1的数据
    model1_data = Model1.objects.all()
    writer.writerow(['Model1字段1', 'Model1字段2', ...])  # 写入表头
    for obj in model1_data:
        writer.writerow([obj.field1, obj.field2, ...])  # 写入每一行数据
    
    # 导出模型2的数据
    model2_data = Model2.objects.all()
    writer.writerow(['Model2字段1', 'Model2字段2', ...])  # 写入表头
    for obj in model2_data:
        writer.writerow([obj.field1, obj.field2, ...])  # 写入每一行数据
    
    # 导出其他模型的数据...
    
    return response
