Django Haystack自定义搜索表单

Question

我已经有了一个基本的django haystack搜索表单，但现在我正在尝试创建一个自定义的搜索表单，其中包含几个要过滤的额外字段。在

我遵循了Haystack文档中关于创建自定义表单和视图的内容，但是当我试图查看表单时，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.

基于SearchForm不应该返回HttpResponse对象吗？在

在表单.py在

^{pr2}$

在视图.py在

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

在网址.py在

from django.conf.urls import include, url
from . import views

urlpatterns = [
    ....
    url(r'^search/calibration/', views.calibration_search, name='calibration_search'),
    ....
]

Answer 1

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

url(r'^search/calibration/', views.calibration_search.as_view(), name='calibration_search'),
