Elasticsearch model import method conflicts with Rails 6.1 activerecord import method

[robmathews]

Hi there! Migrating some code from rails 5.2 to rails 6.1.4 and this code is failing:

objs.import(refresh: true)

with a traceback like this:

vendor/bundle/ruby/3.0.0/gems/activerecord-import-1.2.0/lib/activerecord-import/import.rb:648:in `import_helper': Invalid arguments! (ArgumentError)

which seems to be because rails has natively imported the bulk import feature.

I tried working around this by calling

objs.__elasticsearch__.import(refresh: true)

but instead that cause ActiveRecords import method to still be called, and that calls some serialization code, which ends badly with a "document too large' error, like this:

Elasticsearch::Transport::Transport::Errors::RequestEntityTooLarge

so it doesn't work.

Actually, the problem is more that the ActiveRelation integration is broken, so that instead of updating only the specified records, it is attempting to update all records, ignoring the conditions on the relation.

ie, if you do something like:

Article.where(id: 1).in_batches(of: 50) do |objs|
   objs.__elasticsearch__.import(refresh: true)
end

It will fetch all Article, not the specified one as the import.

I tried this without in_batches(of: 50) and got the same result. ie, this simplifies down to:

objs = Article.where(id: 1)
objs.__elasticsearch__.import(refresh: true)

This is still a problem, .import attempts to update all records and ignores the query or scope.
