Question

我有搜索功能，我还提供用户将搜索结果导出为csv。我的搜索功能正常。但是，导出功能无法收集用户完成的搜索结果。我能理解这个问题背后的原因，但无法找到解决问题的方法。（使用Global变量可能会有所帮助，但我不想使用它）我的搜索查询功能：

def search_query(request):
    result = publication.objects.all()
    query = request.GET.get("query")
    if query:
        result = result.filter(
            Q(title__icontains=query) 
            Q(timeStamp__icontains=query)
        ).distinct()
    user_filter = UserFilter(request.GET, queryset=result)

    return user_filter

我的搜索功能：

def search(request):
    title = "Advanced Search"
    user_filter = search_query(request)
    context = {
        'title': title,
        'filter': user_filter,
    }
    return render(request, "search.html", context)

我的导出功能：

def export_search_csv(request):
    data = search_query(request)
    response = HttpResponse(content_type='text/csv')
    response['Content-Disposition'] = 'attachment;filename=publications.csv'
    writer = csv.writer(response)
    writer.writerow(['Title', 'Published On'])
    for item in data.qs:
        writer.writerow([item.title, item.timeStamp.strftime("%b-%Y")])
    return response

UPD：

html（导出部分）：

<p>
    <h5>
    <a href="{% url 'publication:export_search_csv' %}?{{ request.GET.urlencode }}" class="btn btn-default" style="width: 150px; role="button">
        <span class="glyphicon glyphicon-save">  </span> Export to CSV</a>      
    </h5>
  </p>

main urls.py:

urlpatterns = [
    url(r'^', include('publications.urls', namespace='publication')),
    ]

出版物/ urls.py：

urlpatterns = [
    url(r'^export/csv/$', views.export_search_csv, name='export_search_csv'),
]

请帮忙。

如果您在模板中使用导出到csv链接，可以尝试使用此链接指定当前获取参数，如下所示：

<a href="{% url 'export_search_csv' %}?{{ request.GET.urlencode }}">export to csv</a>

这将允许将当前过滤器参数传递给导出视图。
