django cms 搜索多个站点？

Question

我已经在 django cms 的单个实例中设置了多个站点，并使用 haystack 进行搜索（使用 Solr）。但是，我得到的 search_indexes.py 似乎没有任何效果。就像它被忽略并使用默认值一样。为什么我的search_indexes.py没有生效？

我有以下内容：

settings.py：

HAYSTACK_SITECONF = 'mysite.search_sites'

search_sites.py：

from cms.models import monkeypatch_reverse
import haystack

monkeypatch_reverse()
haystack.autodiscover()

mysite / app / search_indexes.py：

from django.conf import settings
from django.utils.translation import string_concat, ugettext_lazy
from django.utils.html import strip_tags

from haystack import indexes, site

from cms.models.managers import PageManager
from cms.models.pagemodel import Page
from cms.models.pluginmodel import CMSPlugin

def page_index_factory(lang, lang_name):
    if isinstance(lang_name, basestring):
        lang_name = ugettext_lazy(lang_name)

    def get_absolute_url(self):
        if 'cms.middleware.multilingual.MultilingualURLMiddleware' in settings.MIDDLEWARE_CLASSES:
            return '/%s%s' % (lang, Page.get_absolute_url(self))
        else:
            return Page.get_absolute_url(self)

    class Meta:
        proxy = True
        app_label = 'cms'
        if len(settings.LANGUAGES) > 1:
            verbose_name = string_concat(Page._meta.verbose_name, ' (', lang_name, ')')
            verbose_name_plural = string_concat(Page._meta.verbose_name_plural, ' (', lang_name, ')')
        else:
            verbose_name = Page._meta.verbose_name
            verbose_name_plural = Page._meta.verbose_name_plural

    attrs = {'__module__': Page.__module__,
             'Meta': Meta,
             'objects': PageManager(),
             'get_absolute_url': get_absolute_url}

    _PageProxy = type("Page_%s" % lang.title() , (Page,), attrs)

    _PageProxy._meta.parent_attr = 'parent'
    _PageProxy._meta.left_attr = 'lft'
    _PageProxy._meta.right_attr = 'rght'
    _PageProxy._meta.tree_id_attr = 'tree_id'

    class _PageIndex(indexes.SearchIndex):
        site_id = indexes.IntegerField(model_attr="site__id")
        language = lang
        text = indexes.CharField(document=True, use_template=False)
        pub_date = indexes.DateTimeField(model_attr='publication_date')
        login_required = indexes.BooleanField(model_attr='login_required')
        url = indexes.CharField(stored=True, indexed=False, model_attr='get_absolute_url')
        title = indexes.CharField(stored=True, indexed=False, model_attr='get_title')

        def prepare(self, obj):
            self.prepared_data = super(_PageIndex, self).prepare(obj)
            plugins = CMSPlugin.objects.filter(language=lang, placeholder__in=obj.placeholders.all())
            text = ''
            for plugin in plugins:
                instance, _ = plugin.get_plugin_instance()
                if hasattr(instance, 'search_fields'):
                    text += ''.join(strip_tags(getattr(instance, field, '')) for field in instance.search_fields)
                if getattr(instance, 'search_fulltext', False):
                    text += strip_tags(instance.render_plugin())
            self.prepared_data['text'] = text
            return self.prepared_data

        def index_queryset(self):
            qs = _PageProxy.objects.published().filter(title_set__language=lang).distinct()
            if 'publisher' in settings.INSTALLED_APPS:
                qs = qs.filter(publisher_is_draft=True)
            return qs

    return _PageProxy, _PageIndex

for lang_tuple in settings.LANGUAGES:
    lang, lang_name = lang_tuple
    site.register(*page_index_factory(lang, lang_name))

好的，问题出在 search_sites.py 上，它不应该使用自动发现。相反，它需要导入 search_indexes 文件，该文件将为所有插件注册索引：

from cms.models import monkeypatch_reverse
monkeypatch_reverse()
import mysite.app.search_indexes

然后以下脚本在所有站点上运行索引：

import os
import sys

root = os.path.join(os.path.dirname(__file__), '..')
sys.path.insert(0, root)

activate_this = os.path.join(root, 'venv/bin/activate_this.py')
execfile(activate_this, dict(__file__=activate_this))
os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite.settings'

from django.contrib.sites.models import Site
from django.conf import settings

from haystack.management.commands.clear_index import Command as clearCommand
from haystack.management.commands.update_index import Command as updateCommand

clear = clearCommand()
clear.handle(interactive=False)

for site in Site.objects.all():
    settings.SITE_ID = site.id
    update = updateCommand()
    update.handle()
