Facets from many to many fields do not display in template
I tried to use faceting with Haystack on a many to many field. I tried many options to finally end up to a road block. I am able to make it work (apparently) as shown below through the shell. However, when implementing into the template the faceted fields do not show up.
Extract from Django Shell
- from haystack.query import SearchQuerySet
- sqs = SearchQuerySet().facet('type')
- sqs.facet_counts()
- {'fields': {'type': [('Soccer', 2), ('Basketball', 1), ('Golf', 1), ('Swimming', 1)]}, 'dates': {}, 'queries': {}}
Search Index.py
class EventIndex(indexes.SearchIndex, indexes.Indexable):
text = indexes.CharField(document=True, use_template=True)
name = indexes.CharField(model_attr='name')
owner = indexes.CharField(model_attr='user')
created_on = indexes.DateTimeField(model_attr='created_on')
type = indexes.MultiValueField(faceted=True)
def get_model(self):
return Event
def prepare_type(self, obj):
return [(t.name) for t in obj.type.all()]
def index_queryset(self, using=None):
return self.get_model().objects.prefetch_related('type').all()
Template
<!-- Begin faceting. -->
<div>
{% if facets.fields.type %}
<h5>Categories</h5>
{# Provide only the top 5 categories #}
{% for category in facets.fields.type|slice:":5" %}
<a href="{{ request.get_full_path }}&selected_facets=type_exact:{{ type.0|urlencode }}">
{{ type.0 }}
</a>
({{ type.1 }})
{% endfor %}
{% else %}
<p>No categories.</p>
{% endif %}
</div>
event_text.txt
{{ object.name }}
{{ object.description }}
{% for type in event.type.all %}
{{ event.type }}
{% endfor %}
I should be able to see the different types as facets (soccer, basketball, etc..). Instead I get only an empty value.
Categories
()
I believe something is wrong in my template, I guess I should loop through the event.type, but I can't figure this one out...
Thank you!
