我正在尝试使用 django haystack 制作自定义搜索表单,我只是从 haystack 的文档中修改:
表格.py
from django import forms
from haystack.forms import SearchForm
class DateRangeSearchForm(SearchForm):
start_date = forms.DateField(required=False)
end_date = forms.DateField(required=False)
def search(self):
# First, store the SearchQuerySet received from other processing.
sqs = super(DateRangeSearchForm, self).search()
# Check to see if a start_date was chosen.
if self.cleaned_data['start_date']:
sqs = sqs.filter(pub_date__gte=self.cleaned_data['start_date'])
# Check to see if an end_date was chosen.
if self.cleaned_data['end_date']:
sqs = sqs.filter(pub_date__lte=self.cleaned_data['end_date'])
return sqs
到 :
from django import forms
from haystack.forms import HighlightedModelSearchForm
class CustomSearchForm(HighlightedModelSearchForm):
title = forms.CharField(max_length = 100, required = False)
content = forms.CharField(max_length = 100, required = False)
date_added = forms.DateField(required = False)
post_by = forms.CharField(max_length = 100, required = False)
def search(self):
sqs = super(CustomSearchForm, self).search()
if self.cleaned_data['post_by']:
sqs = sqs.filter(content = self.cleaned_data['post_by'])
if self.cleaned_data['title']:
sqs = sqs.filter(content = self.cleaned_data['title'])
if self.cleaned_data['content']:
sqs = sqs.filter(content = self.cleaned_data['content'])
if self.cleaned_data['date_added']:
sqs = sqs.filter(content = self.cleaned_data['date_added'])
return sqs
干草堆.urls:
urlpatterns = patterns('haystack.views',
url(r'^$', search_view_factory(view_class = SearchView, form_class = CustomSearchForm), name='haystack_search'),
)
当我转到 url 时,它显示:AttributeError at /search/
“CustomSearchForm”对象没有属性“cleaned_data”
你们能帮帮我吗?谢谢
然后我尝试评论搜索方法,但是当我向自定义字段提交一个单词时,结果总是什么都没有,只有当我向非自定义字段提交一个单词时它才能给我想要的结果,已经尝试理解这一点一整天,请帮忙
