So I've used django rest framework to serialize my data to make api calls.
Great, that all worked well. Now I wanted to implement a search and return
the serialized data in JSON format like I do with normal data. I feel like
I followed the drf-haystack basic usage guide(
https://drf-haystack.readthedocs.org/en/latest/basic_usage.html) correctly
to get started. But I'm not getting any results when I make a call to the
url. So, I'm going to use this event app. I want to be able to search
through the titles. i.e( "party downtown")
So here's what I'm working with.
Model:
class Event(models.Model):
business = models.ForeignKey(Business)
title = models.CharField(max_length=75)
event_date = models.DateField(blank=True,default=datetime.date.today)
startTime = models.DateTimeField(blank=True,default=datetime.datetime.
now)
endTime = models.DateTimeField(blank=True,null=True)
description = models.TextField(blank=True)
search_indexes.py:
class EventIndex(indexes.SearchIndex,indexes.Indexable):
text = indexes.CharField(document=True,use_template=True)
title = indexes.CharField(model_attr="title")
description = indexes.CharField(model_attr="description")
))
def get_model(self):
return Event
def index_queryset(self,using=None):
return self.get_model().objects.all()
Serializer(EventSearchSerializer):
class EventSearchSerializer(HaystackSerializer):
class Meta:
# The `index_classes` attribute is a list of which search indexes
# we want to include in the search.
index_classes = [EventIndex]
# The `fields` contains all the fields we want to include.
# NOTE: Make sure you don't confuse these with model attributes.
These
# fields belong to the search index!
fields = [
"text", "title", "description"
]
Views: ( I've tried both ways mentioned in the docs. With viewsets and
without):
class EventSearchView(HaystackViewSet):
# `index_models` is an optional list of which models you would like to
include
# in the search result. You might have several models indexed, and this
provides
# a way to filter out those of no interest for this particular view.
# (Translates to `SearchQuerySet().models(*index_models)` behind the
scenes.
index_models = [Event]
serializer_class = EventSearchSerializer
class EventSearchView2(ListModelMixin, HaystackGenericAPIView):
serializer_class = EventSearchSerializer
def get(self,request, *args,**kwargs):
return self.list(request,*args,**kwargs)
Urls:
router = routers.DefaultRouter()
router.register("event/search", EventSearchView, base_name="event-search")
urlpatterns = [
# api url for User to Create, Read, View
url(r'^~api/v1/', include(router.urls)),
url(
regex=r'^~api/v2/search/$',
view = views.EventSearchView2.as_view(),
name="event_search_api"
),]
I perform a search in the url:
url: http://localhost/events/~api/v2/search/?title=club
and I get nothing,but there's data there for sure with that title. I get a
200 OK code back. But 0 results
I'm trying to figure this out, but I got nothing so far. Thanks for reading
this far.
