Elasticsearch-rails: ArgumentError: Invalid arguments!

[afterclassroom]

I had configured elasticsearch, and function of "index" & "search" works on my model name "Discussion".

But I got error of "ArgumentError: Invalid arguments!" when I run below command:

• rake environment elasticsearch:import:all DIR=app/models
• rake environment elasticsearch:import:all
• rake environment elasticsearch:import:model CLASS='Discussion'

Here is the content of log when executing these commands:

I found out the issue. We had used gem "gem 'activerecord-import'" within our system. And when we uninstall this gem, everything works fine.

@afterclassroom The gem might have clashed with the Rake task, but the import process could be also started from code, MyModel.__elasticsearch__.import, using the proxy method, to bypass the import method from the other gem.

I've encountered the same problem. I have both activerecord-import and elasticsearch-model included in my models. Attempting MyModel.__elasticsearch__.import results in an error:

ArgumentError: Invalid arguments!
    from /gems/activerecord-import-0.5.0/lib/activerecord-import/import.rb:199:in `import'
    from /gems/elasticsearch-model-0.1.5/lib/elasticsearch/model/proxy.rb:80:in `method_missing'

elasticsearch/model/proxy.rb:80 appears to invoke the import method on the target (MyModel class, and therefore invoking the import method included from activerecord-import). It looks like the OP removed the gem to solve their problem, but it would be nice to be able to use both gems side by side.

@avinmathew The problem is that the Rake task calls Model.import, not Model.__elasticsearch__.import. Also, you have to require the activerecord-import gem first, so its import() method is respected.

Attempting MyModel.__elasticsearch__.import (...) results in an error

So, when I add this:

require 'activerecord-import'

to the activerecord_article.rb example, I get this:
