Question

我正在尝试将djangohaystack simple backend添加到我的django应用中。我已经尝试过按照教程，但Person中没有任何对象在模板中呈现。我不知道我可能错过了什么。满足{% if query %}条件，但不满足下一个for循环并显示No results to display。

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 %}

这就是我的全部。我知道simplebackend不应该做广泛的搜索，但它必须在完全名称搜索后返回结果，我需要在heroku上部署它，而heroku只支持搜索引擎作为昂贵的附加组件。任何想法，如果他们是什么的我可能错过了吗？

  class PersonDetail(generics.RetrieveUpdateDestroyAPIView):
    serializer_class = PersonSerializer
    permission_classes = (IsAuthenticatedOrReadOnly,)

  def get_object(self):
    person_id = self.kwargs.get('pk',None)
    return Movie.objects.get(pk=person_id)

完全追溯 -

尝试测试

# -*- 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()

我查看了干草堆来源，get_model转移到django19中的应用程序 this is working example

使用过滤器搜索时遇到了类似的问题（使用多个索引模型）。通过在forms.py中添加以下代码解决了这个问题（github链接到django-haystack / haystack / forms.py https://github.com/django-haystack/django-haystack/blob/master/haystack/forms.py）

line = "NOVEL_SERIES, 3256432, 8, 1, 2.364, 4.5404, 9.8341"
types=[str,int,int,int,float,float,float]
key, id, xval, yval, est1, est2, est3 = [f(x) for (f,x) in zip(types,line.split(', '))]

>>> [key, id, xval, yval, est1, est2, est3]
['NOVEL_SERIES', 3256432, 8, 1, 2.364, 4.5404, 9.8341]
>>> key
'NOVEL_SERIES'

For Simple Backend ...这是我的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})

我认为问题在于您的视图部分。修改视图以将代码呈现到某个自定义模板将解决此问题。

干草堆简单搜索。没有显示对象
