Facets from many to many fields do not display in template












0















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 }}&amp;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!

          Can a sorcerer learn a 5th-level spell early by creating spell slots using the Font of Magic feature?

          Image
          28 6 $begingroup$ Per the Font of Magic feature, sorcerer can use Flexible Casting to create 5th-level spell slots at level 7, even though they are not typically available until level 9. You can transform unexpended sorcery points into one spell slot as a bonus action on your turn. The Creating Spell Slots table shows the cost of creating a spell slot of [5th level is 7] If such a sorcerer levels up while still having this 5th-level spell slot, can they choose a 5th-level spell as the spell they gain upon levelling up? The Spellcasting feature states: Additionally, when you gain a level in this class, you can choose one of the sorcerer spells you know and replace it with another spell from the sorcerer spell list, which also must be of a level for which you have spell slots.

          Does disintegrating a polymorphed enemy still kill it after the 2018 errata?

          Image
          up vote 13 down vote favorite 1 After the 2018 errata, the disintegrate spell description now reads: A creature targeted by this spell must make a Dexterity saving throw. On a failed save, the target takes 10d6 + 40 force damage. The target is disintegrated if this damage leaves it with 0 hit points. If you were to polymorph an enemy into a rat and then disintegrate it, would the enemy be disintegrated or would it just return to its original form? I know that for Druids, it’s not an instant kill anymore, but is this the case for polymorph as well? dnd-5e spells polymorph errata share | improve this question edited 18 hours ago

          A Topological Invariant for $pi_3(U(n))$

          Image
          3 3 $begingroup$ Recently, I saw a construction of topological invariant for $pi_3(U(n))$ with $ngeq 2$ : $$ N=frac{1}{24pi^2}int_{S^3} d^3x epsilon^{ijk} Tr[(U^{-1}partial_{x_i}U)(U^{-1}partial_{x_j}U)(U^{-1}partial_{x_k}U)] , $$ where $Uin U(n)$ depends on $boldsymbol{x}=(x_1,x_2,x_3)in S^3$ , $epsilon^{ijk}$ is the Levi-Civita symbol, $i,j,k=1,2,3$ , and the duplicated indexes are summed over. It is claimed that $N$ is an integer, but why? Update 02/02/2019 I think I got an argument for $n=2$ . In this case, $U=e^{i varphi} q$ with $qin SU(2)$ . Due to the trace and the Levi-Civita symbol in $N$ , $varphi$ does not contribute to $N$ . As $Tr[q^{dagger}partial_i q]=0$ and $(q^{dagger}partial_i q)^{dagger}=-q^{dagger}partial_i q$ , $q^{dagger}partial_i q$ in geneeral has the form $q^{dagger}partia
