使用zc.buildout從Django添加到solr索引時出現問題

Question

我正在嘗試讓Apache Solr在我的zc.buildout環境中運行。

我已經定義了一個簡單的模型：

class NewsItem(models.Model):
    title = models.CharField(blank=False, max_length=255, help_text=u"Title of this news item")
    slug = models.SlugField(blank=False, help_text=u"Slug will be automatically generated from the title")
    article = models.TextField(help_text=u"The body text of this news item")
    created_on = models.DateTimeField(auto_now_add = True)
    updated_on = models.DateTimeField(auto_now = True)
    published = models.BooleanField(default=True)

    def __unicode__(self):
        return self.title

search_index.py：

import datetime
from haystack.indexes import *
from haystack import site
from appname.models import *


class NewsItemIndex(RealTimeSearchIndex):
    text = CharField(document=True, use_template=True)

    def get_queryset(self):
        """Used when the entire index for model is updated."""
        return NewsItem.objects.all()


site.register(NewsItem, NewsItemIndex)

search_sites.py定義：

import haystack
haystack.autodiscover()

設置文件包含：

HAYSTACK_SITECONF = 'appname.search_sites'
HAYSTACK_SEARCH_ENGINE = 'solr'
HAYSTACK_SOLR_URL = 'http://127.0.0.1:8983/solr'
HAYSTACK_SEARCH_RESULTS_PER_PAGE = 30
HAYSTACK_INCLUDE_SPELLING = True

'haystack'列在INSTALLED_APPS中，pysolr列在setup.py中的'install_requires'中（由buildout提供）

我的buildout.cfg包含solr-files ， solr ， solr-conf和supervisor 。

我已將${buildout:directory}/solr-conf到[mkdir]路徑。

buildout.cfg中的supervisor和solr部分如下所示：

[supervisor]
recipe = collective.recipe.supervisor
port = localhost:9001
user = admin
password = admin
plugins =
   superlance

# solr security settings: see
# http://docs.codehaus.org/display/JETTY/Connectors+slow+to+startup
programs =
   10 solr     (startsecs=10) java [-Djava.security.egd=file:/dev/urandom -jar start.jar] ${buildout:parts-directory}/solr true

eventlisteners =
   SolrHttpOk TICK_60 ${buildout:bin-directory}/httpok [-p solr -t 20 http://localhost:8983/solr/]


[solr-files]
recipe = hexagonit.recipe.download
url = ftp://mir1.ovh.net/ftp.apache.org/dist/lucene/solr/1.3.0/apache-solr-1.3.0.tgz
md5sum = 23774b077598c6440d69016fed5cc810
strip-top-level-dir = true

[solr]
recipe = collective.recipe.solrinstance
solr-location = ${buildout:parts-directory}/solr-files
host = localhost
port = 8983

unique-key = uniqueID
default-search-field = text

index =
   name:uniqueID type:string indexed:true stored:true required:true
   name:text type:string indexed:true stored:true required:false omitnorms:false multivalued:true

[solr-conf]
recipe = iw.recipe.cmd
on_install = true
on_update = true
cmds =
   cp -v ${buildout:directory}/solr-conf/jetty.xml ${solr:jetty-destination}
   cp -v ${buildout:directory}/solr-conf/schema.xml ${solr:schema-destination}
   cp -v ${buildout:directory}/solr-conf/stopwords_fr.txt ${solr:schema-destination}

[solr-rebuild]
recipe = iw.recipe.cmd
on_install = true
on_update = true

# since solr is not started by solr-instance but supervisord, solr-instance has
# no pid file and thinks that solr is down. Thus we must run it with
# solr-instance to be able to "solr-instance purge"
cmds =
   ${buildout:bin-directory}/supervisorctl stop solr
   cp -v ${buildout:directory}/solr-conf/schema.xml ${solr:schema-destination}
   ${buildout:bin-directory}/solr-instance start
   COUNT=15; echo "Waiting $COUNT s"; sleep $COUNT
   ${buildout:bin-directory}/solr-instance purge
   time ${buildout:bin-directory}/${django:control-script} rebuild_index
   ${buildout:bin-directory}/solr-instance stop
   ${buildout:bin-directory}/supervisorctl start solr

當我運行$ bin/buildout install solr-rebuild ，我得到以下輸出：

`/appname/solr-conf/schema.xml' -> `/appname/parts/solr/solr/conf/schema.xml'
Solr started with pid 16023

同樣，運行$ bin/django rebuild_index或$ bin/buildout update_index抱怨'django_ct'：

Failed to add documents to Solr: [Reason: ERROR:unknown field 'django_ct']

（我要嘗試的一件事是將solr更新到最新版本..如果這樣做會報告..）

我不知道下一步該在哪里。搜索谷歌，群組和stackoverflow並沒有讓我超越這一點。 提前致謝！

好的，問題解決了。 更新到Solr 1.4.1（奇怪的是，之后重新啟動）就可以了。
