草垛不索引我的多值

Question

我試圖讓一個MultiValueField被索引，但它不工作。以下是我有：

 
class Public_PollIndex(SearchIndex): 
    text = CharField(model_attr='question', document=True, use_template=True) 
    date_created = DateTimeField(model_attr='date_created') 
    choices = MultiValueField() 

    def get_model(self): 
     return Public_Poll 

    def prepare_choices(self, obj): 
     # For some silly reason we get (u"choice",) instead of just u"choice" 
     # So we unpack... 
     c = [ str(c) for (c,) in obj.choice_set.values_list('choice') ] 
     return c 

    def index_queryset(self): 
     return self.get_model().objects.filter(date_created__lte=datetime.datetime.now()) 

然後，我有模板：

 
{{ object.question }} 
{{ object.date_created }} 
{{ object.choices }} 

與調試prepare_choices步進通過不會返回類似['foo', 'bar']

但是，當我看着Solr的或Public_PollIndex(Public_Poll.objects.get(id=1)).load_all_queryset()我沒有看到choices字段索引，但其他兩個是。

Answer 1

如何檢查SearchQuerySet？ Public_PollIndex(Public_Poll.objects.get(id=1)).load_all_queryset()回報模式QuerySet代替SearchQuerySet

嘗試

SearchQuerySet()[0].text 
SearchQuerySet()[0].choices 

而且，在模板中，渲染選擇在for循環

{% for choice in object.choices %} 
{{ choice }} 
{% endfor %} 

此外，

return obj.choice_set.values_list('choice', flat=True) 

# instead of 
c = [ str(c) for (c,) in obj.choice_set.values_list('choice') ] 
return c
