干草堆没有索引我的多值 [英] haystack isn't indexing my multivalue

问题描述

我想要获得一个 MultiValueField 被编入索引，但它只是不工作。这是我有的：

I'm trying to get a MultiValueField to be indexed, but it's just not working. Here is what I have:

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())

然后我在模板中：

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

使用调试器进行 prepare_choices 返回类似 ['foo'，'bar']

Stepping through with the debugger prepare_choices DOES return something like ['foo', 'bar']

但是当我查看solr或 Public_PollIndex（Public_Poll.objects.get（id = 1））。load_all_queryset（）我没有看到

But when I look into solr or Public_PollIndex(Public_Poll.objects.get(id=1)).load_all_queryset() I don't see the choices field indexed, but the other two are.

推荐答案

如何查看 SearchQuerySet ？ public_PollIndex（Public_Poll.objects.get（id = 1））。load_all_queryset（）返回模型 QuerySet 而不是 SearchQuerySet

How do you check the SearchQuerySet? Public_PollIndex(Public_Poll.objects.get(id=1)).load_all_queryset() returns model QuerySet instead of SearchQuerySet

尝试

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

另外，在模板中，在forloop中呈现选择

Also, in the template, render choices in forloop

{% 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
