Question

我正在尝试django-haystack飞快移动。 Django Haystack和Whoosh搜索有效，但页面中没有给出结果。我也查过这个类似的问题

Django-haystack-whoosh is giving no results

Django Haystack & Whoosh Search Working, But SearchQuerySet Return 0 Results

点冻结

python==3.6
django==2.0.7
Whoosh==2.7.4

-e git://github.com/django-haystack/django.haystack.git#egg=django-haystack

这是我的代码：

search_indexes.py

import datetime
from haystack import indexes
from search.models import Articles

class ArticlesIndex(indexes.SearchIndex, indexes.Indexable):
    text = indexes.CharField(document = True, use_template = true
    pub_date = indexes.DateTimeField(model_attr = 'pub_date')
    content_auto = indexes.EdgeNgramField(model_attr='title')

    def get_model(self):
        return Articles

    def index_queryset(self, using=None)
        return self.get_model().objects.filter(pub_date__lte=datetime.datetime.now())

views.py

from .models import Articles
from haystack.query import SearchQuerySet

def home(request):
      article=SearchQuerySet().autocomplete(content_auto=request.POST.get('search_text', '')
return render(request, 'home.hmtl')

home.html

<form method='post'action=''>
{% csrf_token %}
<table>
   {{form.as_table}}
    <tr>
       <td><input type='search'></td>
       <td><input type='submit' value= 'Search'></td>
    </tr>
</table>
{% if query %}
<h3>Results</h3>
    {% for article in articles %}
      <p><a href="{{article.object.get_absolute_url}}">{{article.object.title}}</a></p>
    {% empty %}
      <p>No results found </p>
    {% endfor %}
{% endif %}
</form>

models.py

from django.db import models

class Articles(models.Model):
     title = models.CharField(max_length = 255)
     body = models.TextField()
     pub_date = models.DateTimeField(auto_now_add=True)

     def __str__(self):
          return self.title

projectfile / templates / indexes / search / articles_text.txt

    {{object.title}}
    {{object.body}}

settings.py

    INSTALLED_APPS = [
       'haystack',
       'whoosh',
       ]
    WHOOSH_INDEX=[os.path.join(BASE_DIR, 'whoosh/'),]
    HAYSTACK_CONNECTIONS = {
       'default': {
         'ENGINE': 'haystack.backends.whoosh_backend.WhooshEngine',
         'PATH': os.path.join(os.path.dirname(__file__), 'whoosh_index'),
            },
          }

我运行了python3 manage.py rebuild_index，它说在app文件夹中索引了3条文章和我的search_indexes.py文件。

Mistake在您的视图中，在视图中您未呈现文章，因此视图应为：

def home(request):
  articles = SearchQuerySet().autocomplete(content_auto=request.POST.get('search_text', '')
  return render(request, 'home.html', {'articles':articles})

为什么要使用自动完成功能？

django haystack whoosh不显示任何错误，也没有结果
