如何在Django 2中搜索数据后导出csv文件？

import csv
from django.http import HttpResponse
from django.db.models import Q
from .models import YourModel

def search_and_export_csv(request):
    # 获取搜索关键词
    keyword = request.GET.get('keyword', '')

    # 在你的模型中执行搜索操作
    queryset = YourModel.objects.filter(Q(field1__icontains=keyword) | Q(field2__icontains=keyword))

    # 创建CSV响应对象
    response = HttpResponse(content_type='text/csv')
    response['Content-Disposition'] = 'attachment; filename="search_results.csv"'

    # 创建CSV写入器
    writer = csv.writer(response)
    writer.writerow(['Field 1', 'Field 2', 'Field 3'])  # 根据你的模型字段修改标题行

    # 将搜索结果写入CSV文件
    for obj in queryset:
        writer.writerow([obj.field1, obj.field2, obj.field3])  # 根据你的模型字段修改数据行

    return response

from django.urls import path
from .views import search_and_export_csv

urlpatterns = [
    # 其他URL路径...
    path('search/', search_and_export_csv, name='search_and_export_csv'),
]

<form action="{% url 'search_and_export_csv' %}" method="get">
    <input type="text" name="keyword" placeholder="搜索关键词">
    <button type="submit">搜索并导出CSV</button>
</form>
