自定义视图不显示带有Elastic Search的Django Haystack中的结果

Question

I'm starting using Django Haystack with Elasticsearch.

All right until I started make a Custom View following the simple example in readthedocs .

search_indexes.py:

class ExperimentIndex(indexes.SearchIndex, indexes.Indexable):
    text = indexes.CharField(document=True, use_template=True)
    owner = indexes.CharField(model_attr='owner')

    def get_model(self):
        return Experiment

    def index_queryset(self, using=None):
        return self.get_model().lastversion_objects.all()

urls.py:

url(r'^search/?$', NepSearchView.as_view(), name='search_view')

urls.py before (without Custom View):

url(r'^search/', include('haystack.urls'))

views.py

class NepSearchView(SearchView):

    def get_queryset(self):
        queryset = super(NepSearchView, self).get_queryset()
        if not self.request.user.is_authenticated and \
                self.request.user.groups.filter(name='trustees').exists():
            return queryset  # (with some filter)
        else:
            return queryset

search.html:

{# ... #}
{% for result in page.object_list %}
{% if result.model_name == 'experiment' %}
{% include 'search/experiments.html' %}
{% endif %}
{% if result.model_name == 'study' %}
{% include 'search/studies.html' %}
{% endif %}
{% if result.model_name == 'group' %}
{% include 'search/groups.html' %}
{% endif %}
{% if result.model_name == 'experimentalprotocol' %}
{% include 'search/experimental_protocol.html' %}
{% endif %}
{# ... #}

Well, the fact is when using default Haystack SearchView I've got the correct matches, while when introducing NepSearchView , page.object_list is empty and I get No results found. in template.

I already ran manage.py rebuild_index , searched extensively in web but couldn't find nothing that explains what I'm missing.

Answer 1

It seems that the page.object_list variable name for the queryset does not exist. Try the object_list without the 'page' prefix.

instead of

{% for result in page.object_list %}

use

{% for result in object_list %}

Alternatively you can provide a custom variable name in the view by appending something like this

context_object_name = 'haystack_objects'

and use it in the template

{% for result in haystack_objects %}
