Django Haystack：Heroku搜索框插件无法运行rebuild_index

Question

我想在Heroku上使用elasticsearch实现Haystack搜索我的Django应用程序。

我按照这里的说明：https://devcenter.heroku.com/articles/searchbox#using-haystack-with-django设置搜索框插件。

settings.py：

from urlparse import urlparse 

es = urlparse(os.environ.get('SEARCHBOX_URL')) 
port = es.port 

HAYSTACK_CONNECTIONS = { 
    'default': { 
     'ENGINE': 'haystack.backends.elasticsearch_backend.ElasticsearchSearchEngine', 
     'URL': es.scheme + '://' + es.hostname + ':' + str(port), 
     'INDEX_NAME': 'haystack', 
    }, 
} 

if es.username: 
    HAYSTACK_CONNECTIONS['default']['KWARGS'] = {"http_auth": es.username + ':' + es.password} 

然而，当我尝试运行

heroku run python manage.py rebuild_index 

我收到以下错误跟踪：

Removing all documents from your index because you said so.

我在做什么错？如何在Heroku上编制我的数据？

编辑：我也试过在Heroku中使用Bonsai插件。我也遇到类似的错误。

在此先感谢。

Answer 1

在失去了很多头发（：P）后，我找出了问题所在！

这是问题：

port = es.port 

es.port返航 “无”。更改为

port = es.port or 80 

现在它工作。

原来我从文档中复制代码时遗留了“或80”部分。啧！
