我是django和haystack的菜鸟, 这是我的表格,它扩展了haystack SearchForm
from haystack.forms import SearchForm
from ksaprice_app.models import ProductDiff, Vendor
from django import forms
from haystack.query import SearchQuerySet
class ProductsSearchForm(SearchForm):
vendor_list=Vendor.objects.all().values_list('vendor_name')
OPTIONS=( (item,str(item)) for item in vendor_list)
print OPTIONS select_vendor=forms.MultipleChoiceField(widget=forms.CheckboxSelectMultiple,choices=OPTIONS, required=False)
def __init__(self, *args, **kwargs):
super(ProductsSearchForm, self).__init__(*args, **kwargs)
def search(self):
sqs=super(ProductsSearchForm, self).search()
if not self.is_valid():
return self.no_query_found()
#check to see if the submitted is clean and then filter
if self.is_valid():
if self.cleaned_data['select_vendor']:
#name of the field in html will be by default form field name
vendor_filter=self.cleaned_data['select_vendor']
#v_filter=vendor_filter[0].replace("(u'","").replace("',)","")
v_filter=vendor_filter[0]
print v_filter
#sqs=SearchQuerySet().filter(product_vendor_name=v_filter)[:10]
sqs=sqs.filter(product_vendor_name=v_filter)[:10] ##error is here
return sqs
def no_query_found(self):
return self.searchqueryset.all()[:10]
这是视图
def ProductsSearch(request):
#instantiate the form with parameters from get method
form = forms.ProductsSearchForm(request.GET)
#calling search method here that fetches the search result
context_var={}
context_var['products'] = form.search()
context_var['form']=forms.ProductsSearchForm
print context_var
return render_to_response('ksaprice_app/product_search.html', {'context_var': context_var})
在sqs.filter,我收到此错误'list' object has no attribute 'filter'
。我关注了documentation和example。我无法弄清楚,问题是什么? search方法返回list对象而不是SearchQuerySet对象,因此无法找到filter属性。请帮忙。
我使用的是python 2.7.10,Django 1.8.4和solr 4.10.2
sqs是

3-4天后,我到达了解决方案。
解决方案1-:架构更改
第1步:转到您的收藏管理架构文件并进行修改
第2步:查找并将<field name="django_ct" type="text_general"/>
替换为<field name="django_ct" type="string"/>
解决方案2-:破解核心文件
Step1: sudo vim / home / your path / site-packages / haystack / backends / solr_backend.py
第2步:查找并将app_label, model_name = raw_result[DJANGO_CT].split('.')
替换为app_label, model_name = raw_result[DJANGO_CT][0].split('.')
答案 1 :(得分:0)
第一步:
sudo vim /home/your path/site-packages/haystack/backends/solr_backend.py
Step2:查找和替换
app_label, model_name = raw_result[DJANGO_CT].split('.')
与
app_label, model_name = raw_result[DJANGO_CT][0].split('.')
第三步:查找和替换
result = result_class(app_label, model_name, raw_result[DJANGO_ID], raw_result['score'], **additional_fields)
与
result = result_class(app_label, model_name, raw_result[DJANGO_ID][0], raw_result['score'], **additional_fields)
