我有一个基本的django-haystack SearchForm工作正常，但现在我正在尝试创建一个自定义搜索表单，其中包含一些额外的字段来过滤 .
我已经关注创建自定义表单和视图的Haystack文档，但是当我尝试查看表单时，我只能得到错误：
ValueError at /search/calibration/
The view assetregister.views.calibration_search didn't return an HttpResponse object. It returned None instead.
不应该基于SearchForm来处理返回HttpResponse对象吗？
forms.py
from django import forms
from haystack.forms import SearchForm
class CalibrationSearch(SearchForm):
calibration_due_before = forms.DateField(required=False)
calibration_due_after = forms.DateField(required=False)
def search(self):
#First we need to store SearchQuerySet recieved after / from any other processing that's going on
sqs = super(CalibrationSearch, self).search()
if not self.is_valid():
return self.no_query_found()
#check to see if any date filters used, if so apply filter
if self.cleaned_data['calibration_due_before']:
sqs = sqs.filter(calibration_date_next__lte=self.cleaned_data['calibration_due_before'])
if self.cleaned_data['calibration_due_after']:
sqs = sqs.filter(calibration_date_next__gte=self.cleaned_data['calibration_due_after'])
return sqs
views.py
from .forms import CalibrationSearch
from haystack.generic_views import SearchView
from haystack.query import SearchQuerySet
def calibration_search(SearchView):
template_name = 'search/search.html'
form_class = CalibrationSearch
queryset = SearchQuerySet().filter(requires_calibration=True)
def get_queryset(self):
queryset = super(calibration_search, self).get_queryset()
return queryset
urls.py
from django.conf.urls import include, url
from . import views
urlpatterns = [
....
url(r'^search/calibration/', views.calibration_search, name='calibration_search'),
....
]

Haystack的
SearchView是一个基于类的视图，添加urls条目时必须调用.as_view()类方法 .
