Question

这是我的观点

class SingleNewsView(ListView):
model = News
form_class = SearchForm
template_name = "single_news.html"



def get(self, request, pk, **kwargs):
    self.pk = pk

    self.pub_from = request.GET.get('pub_date_from',False)
    self.pub_to = request.GET.get('pub_date_to',False)
    self.crawlers = request.GET.get('crawler',False)

    print self.crawlers


    return super(SingleNewsView,self).get(request,pk, **kwargs)



def get_context_data(self, **kwargs):

    context = super(SingleNewsView,self).get_context_data(**kwargs)
    context["form"] = SearchForm#(self.request.GET)
    if self.pub_from and self.pub_to and self.crawlers:
        context["something"] = News.objects.filter(category_id=self.pk).filter(published_date__range=(self.pub_from,self.pub_to), crawler=self.crawlers)
    else:
        context["something"] = News.objects.filter(category_id=self.pk)

    return context

我想将新闻下载为csv。当我点击新闻列表页面上的“下载CSV”时，我想下载过滤后的查询。我怎样才能做到这一点？？任何帮助？

Answer 1

Django有自己的csv library。如果这不适合您正在寻找的东西，可以查看django-data-export。祝你好运，希望这有帮助！

Answer 2

我使用xlwt将模型导出为excel，我认为此代码可以FYI

from xlwt import Workbook
def get(self, request, *args, **kwargs):
    book = Workbook(encoding='utf-8')
    // fill book with your data here...
    response = HttpResponse(content_type='application/ms-excel')
    book.save(response)
    response['Content-Disposition'] = 'attachment; filename="%s"' % self.excel_file_name.encode("utf-8")
    response['Cache-Control'] = 'no-cache'
    return response

Answer 3

我在django docs帮助中找到了以下代码段：

import csv
from django.http import HttpResponse

def some_view(request):
    # Create the HttpResponse object with the appropriate CSV header.
    response = HttpResponse(content_type='text/csv')
    response['Content-Disposition'] = 'attachment; filename="somefilename.csv"'

    writer = csv.writer(response)
    writer.writerow(['First row', 'Foo', 'Bar', 'Baz'])
    writer.writerow(['Second row', 'A', 'B', 'C', '"Testing"', "Here's a quote"])

    return response
