Using django-haystack, how do I order results by content type

问题

I'm using django-haystack for a search page on my site, and I want to order all the results by their content type. Is there a way I can do that? To make it simpler, suppose I have a single application and several classes. Thanks in advance

回答1:

from How to order search results by Model:

You can do SearchQuerySet().order_by('django_ct'). As a warning, this throws out relevancy. The only way to keep relevancy & group by model is either to run many queries (one per model - usually performant thanks to query caching) or to run the query and post-process the results, regrouping them as you go.

from searchindex api:

Haystack reserves the following field names for internal use: id, django_ct, django_id & content. The name & type names used to be reserved but no longer are.

You can override these field names using the HAYSTACK_ID_FIELD, HAYSTACK_DJANGO_CT_FIELD & HAYSTACK_DJANGO_ID_FIELD if needed.

Not sure what you mean by content type, but if you are talking about group by models, I have this working

        {% with page.object_list as results %}
            {% regroup results|dictsort:"verbose_name_plural" by verbose_name_plural as grouped_objects %}
            {% for ct in grouped_objects %}
                {{ ct.grouper }}
                {% for result in ct.list %}
                    <p>
                        <a href="{{ result.object.get_absolute_url }}">{{ result.object }}</a>
                    </p>
                {% endfor %}
            {% empty %}
                <p>No results found.</p>
            {% endfor %}
        {% endwith %}
