我有同樣的問題,使用草垛,Django的CMS,cmsplugin,博客和其他一些應用程序,以及一個設置。
我剛剛爲cmsplugin-blog和haystack創建了一個自定義搜索索引,靈感來自用於django-cms-search中常規CMS頁面的索引。看看它,它可以幫助你創建自己的。
from haystack import indexes
from haystack import site
from cmsplugin_blog.models import Entry, EntryTitle
from cms.models.pluginmodel import CMSPlugin
from django.utils.encoding import force_unicode
import re
def _strip_tags(value):
"""
Returns the given HTML with all tags stripped.
This is a copy of django.utils.html.strip_tags, except that it adds some
whitespace in between replaced tags to make sure words are not erroneously
concatenated.
"""
return re.sub(r'<[^>]*?>', ' ', force_unicode(value))
class BlogIndex(indexes.SearchIndex):
text = indexes.CharField(document=True)
url = indexes.CharField(stored=True, indexed=False, model_attr='get_absolute_url')
title = indexes.CharField(stored=True, indexed=False)
pub_date = indexes.DateTimeField(model_attr='pub_date', null=True)
def get_model(self):
return Entry
def index_queryset(self):
"""Used when the entire index for model is updated."""
return self.get_model().objects.filter(is_published=True)
def prepare_title(self, obj):
return EntryTitle.objects.filter(entry=obj)[0]
def prepare_text(self, obj):
title = EntryTitle.objects.filter(entry=obj)[0]
placeholder_plugins = CMSPlugin.objects.filter(placeholder__in=obj.placeholders.all())
text = force_unicode(title)
plugins = list(placeholder_plugins)
for base_plugin in plugins:
instance, plugin_type = base_plugin.get_plugin_instance()
if instance is None:
# this is an empty plugin
continue
if hasattr(instance, 'search_fields'):
text += u' '.join(force_unicode(_strip_tags(getattr(instance, field, ''))) for field in instance.search_fields)
if getattr(instance, 'search_fulltext', False) or getattr(plugin_type, 'search_fulltext', False):
text += _strip_tags(instance.render_plugin(context=RequestContext(request))) + u' '
return text
site.register(Entry, BlogIndex)
我會考慮把cmsplugin-博客的叉後在github上這個搜索索引的防彈版本。隨時在有用的地方使用它。
