Haystack simple search. No objects displayed

Question

I am trying to add djangohaystack simple backend into my django app. I've tried following the tutorial but none of the objects in Person are being rendered in the template. I have no idea what I might have missed. The {% if query %} condition is satisfied but the next for loop is not satisfied and No results to display is displayed.

models.py

class Person(models.Model):
    person_name = models.CharField(max_length=200)
    score = models.FloatField()

search_indexes.py

class PersonIndex(indexes.SearchIndex, indexes.Indexable):
    text = indexes.CharField(document=True, use_template=True)
    person_name = indexes.CharField(model_attr='person_name')

    def get_model(self):
        return Person

    def index_queryset(self, using=None):
         """Used when the entire index for model is updated."""
        return self.get_model().objects.all()

site.register(Person, PersonIndex)

note_text

{{ object.person_name }}

search.html

{% if query %}
    <h3>Results</h3>

    {% for result in page.object_list %}
        <p>
            <a href="{{ result.object.get_absolute_url }}">{{ result.object.person_name }}</a>
        </p>
    {% empty %}
        <p>No results found.</p>
    {% endfor %}
{% endif %}

This is all that I have . I know simplebackend is not supposed to do an extensive search but it must return results after exact name search and I need to deploy this on heroku and heroku only supports search engines as pricey add-ons.Any idea if their is something that I might have missed?

Answer 1

try to test

# -*- coding: utf-8 -*-
import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "[look at manage.py]")

import django

from django.core.management import call_command
from haystack.query import SearchQuerySet

django.setup()

call_command('rebuild_index')

print SearchQuerySet().all()

I looked in haystack sources, get_model moved to apps in django19 this is working example

I had a similar problem when searching with filters (using multiple index models). Fixed the issue by adding the below code in forms.py (github link to django-haystack/haystack/forms.py https://github.com/django-haystack/django-haystack/blob/master/haystack/forms.py )

from haystack.utils.app_loading import haystack_get_model

Answer 3

For Simple Backend...This is My View.py

from haystack.utils import Highlighter
from haystack.query import SearchQuerySet
def search_title(request):
    query = request.POST.get("search_text",'&nbsp')
    food = SearchQuerySet().models(Food).filter(content__exact = query)
    veg = SearchQuerySet().models(Veg).using('default').autocomplete(content_auto = query).highlight()
    beverage = SearchQuerySet().models(Beverage).autocomplete(content_auto = query)
    food = Highlighter(food)

    return render(request,'food/products.html',{'food':food,'veg':veg,'beverage':beverage,'query':query})

i Think Problem lies in your view part.Modifying your view to render code to some custom template will solve this.
