I am developing a project with HayStack+ElasticSearch for search engine and I am having hard time to get around it. I've setup models and Inexing for the models as shown below:
models.py:
from django.db import models
from django.core.urlresolvers import reverse
class Product(models.Model):
title = models.CharField(max_length=500)
description = models.TextField(blank=True, null=True)
image = models.ImageField(upload_to='products/')
price = models.DecimalField(max_digits=20, decimal_places=2)
sku = models.CharField(null=True, max_length=100)
url = models.URLField(blank=True)
displayed_category = models.CharField(null=True, max_length=500)
categories = models.ManyToManyField('Category', blank=True)
default = models.ForeignKey(
'Category', related_name='default_category', null=True, blank=True
)
def __unicode__(self):
return self.title
def get_absolute_url(self):
return reverse("product_detail", kwargs={"pk": self.pk})
class Category(models.Model):
title = models.CharField(max_length=120, unique=True)
slug = models.SlugField(unique=True)
description = models.TextField(null=True, blank=True)
timestamp = models.DateTimeField(auto_now=False, auto_now_add=True)
def __unicode__(self):
return self.title
Views.py:
from datetime import date
from .models import Product
from django.views.generic.list import ListView
from django.views.generic.detail import DetailView
from django.core.paginator import Paginator
from haystack.generic_views import SearchView
class ProductListView(ListView):
model = Product
paginate_by = 10
class ProductDetailView(DetailView):
model = Product
class ProductSearchView(SearchView):
model = Product
def get_queryset(self):
queryset = super(ProductSearchView, self).get_queryset()
# further filter queryset based on some set of criteria
return queryset
def get_context_data(self, *args, **kwargs):
context = super(ProductSearchView, self).get_context_data(*args, **kwargs)
context["query"] = self.request.GET.get("q")
return context
search_index.py:
from haystack import indexes
from .models import Product
class TweetIndex(indexes.SearchIndex, indexes.Indexable):
title = indexes.CharField(model_attr='title')
text = indexes.EdgeNgramField(model_attr='text', document=True, use_template=True)
def prepare_title(self, obj):
return obj.title or ''
def get_model(self):
return Product
Project urls.py:
from django.conf.urls import include, url
from django.contrib import admin
from django.conf import settings
from django.conf.urls.static import static
from products.views import ProductSearchView
urlpatterns = [
url(r'^$', 'shopsy.views.home', name='home'),
url(r'^admin/', include(admin.site.urls)),
url(r'^products/', include('products.urls')),
url(r'^search/', ProductSearchView.as_view()),
url(r'search/$', include('haystack.urls')),
]
if settings.DEBUG:
urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)
urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
App urls.py:
from django.conf.urls import url
from .views import ProductListView, ProductDetailView, ProductSearchView
urlpatterns = [
url(r'^$', ProductListView.as_view(), name='products'),
url(r'^(?P<pk>\d+)/$', ProductDetailView.as_view(), name='product_detail'),
]
settings.py:
HAYSTACK_CONNECTIONS = {
'default': {
'ENGINE': 'haystack.backends.elasticsearch_backend.ElasticsearchSearchEngine',
'URL': 'http://127.0.0.1:9200/',
'INDEX_NAME': 'haystack',
},
}
HAYSTACK_SIGNAL_PROCESSOR = 'haystack.signals.RealtimeSignalProcessor'
INTERNAL_IPS = ('127.0.0.1',)
With all the above settings when I run "manage.py rebuild_index" I get the following error.
Removing all documents from your index because you said so.

Please advise if I am doing something or all the way wrong.
If the ES server is not responding it could be for several reasons:
In your case, it was the third option. You just need to install Elasticsearch as explained in the Django Haystack docs, start it and then it will work.
