盆景:使用create_index!或者:force选项来创建它

在过去的4周里,我一直在与Bonsai和Elasticsearch进行一场激烈的战斗,这在某种程度上令人沮丧,因为几个月前我让它在另一个应用程序上工作。
我的应用程序崩溃了,当我去Heroku时,我得到了“应用程序错误”警告。当我结账Herkou Logs时,我发现了一些我认为是问题的东西:

2016-08-31T23:23:47.189996+00:00 heroku[web.1]: Process exited with status 1

特别是这一行:

 import': professors does not exist to be imported into. Use create_index! or the :force option to create it. (ArgumentError)

在Localhost上一切正常,但它与Heroku崩溃了。我发现this question我认为与我的相似,其中一个答案是尝试:

    $ rails console

# Create the index for Service model on elasticsearch
> Service.__elasticsearch__.create_index!
=> {"acknowledged"=>true}

# Import current Service records into the index
> Service.import
  Service Load (207.3ms)  SELECT  "services".* FROM "services"  ORDER BY "services"."id" ASC LIMIT 1000

# Sample search returning total results
> Service.__elasticsearch__.search("mykeyword").results.total
=> 123

但每当我在Heroku heroku run rails console中运行rails控制台时,我都会遇到相同的错误:

/app/vendor/bundle/ruby/2.3.0/gems/elasticsearch-model-0.1.9/lib/elasticsearch/model/importing.rb:118:in `import': professors does not exist to be imported into. Use create_index! or the :force option to create it. (ArgumentError)
from /app/vendor/bundle/ruby/2.3.0/gems/elasticsearch-model-0.1.9/lib/elasticsearch/model.rb:116:in `import'

1 个答案:

答案 0 :(得分:5)

只需使用Service.import(force: true)导入数据。

如果索引已经存在,它将删除索引并在导入数据之前重新创建它。

如果索引不存在,它将直接创建索引和导入数据。

所以不再需要Service.__elasticsearch__.create_index!
