6. Search and the Django-CMS

Currently the best way to integrate search with the Django-CMS is Haystack, however it is not officially supported.

6.1. Haystack

If you go the Haystack way, you’ll need a search_indexes.py.　Haystack doesn’t care if it’s in the same app as the models, so you can put it into any app within your project.

Here is an example untested and unsupported search_indexes.py:

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

from haystack import indexes, site

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

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

    def get_absolute_url(self):
        return '/%s%s' % (lang, Page.get_absolute_url(self))

    class Meta:
        proxy = True
        app_label = 'cms'
        verbose_name = string_concat(Page._meta.verbose_name, ' (', lang_name, ')')
        verbose_name_plural = string_concat(Page._meta.verbose_name_plural, ' (', lang_name, ')')
        
    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):
        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 = obj.cmsplugin_set.filter(language=lang)
            text = ''
            for plugin in plugins:
                instance, _ = plugin.get_plugin_instance()
                if hasattr(instance, 'search_fields'):
                    text += ''.join(getattr(instance, field) for field in instance.search_fields)
            self.prepared_data['text'] = text
            return self.prepared_data
        
        def get_queryset(self):
            return _PageProxy.objects.published().filter(title_set__language=lang, publisher_is_draft=False).distinct()

    return _PageProxy, _PageIndex

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