Polymorphic association generates migration with syntax error.

[joshuapinter]

Hey there.

Using v 2.0.1 out of master. I have an Attachment model that is polymorphic with the following definition in the model:

class Attachment < ActiveRecord::Base
  belongs_to :attachable,  polymorphic: true
end

Using rake db:find_indexes it generates the following migration suggestion:

class AddMissingIndexes < ActiveRecord::Migration
  def change
    add_index :attachments, [:["attachable_id", "attachable_type"]]
  end
end

And when running rake db:migrate I get:

syntax error, unexpected '[', expecting tSTRING_CONTENT or tSTRING_DBEG or tSTRING_DVAR or tSTRING_END
    add_index :attachments, [:["attachable_id", "attachable_type"]]

I can look into it if you want to point me in the right direction...

Thanks!

@joshuapinter @Vorob-Astronaut hey guys. I've just released 2.0.2 with a fix for this. Can you test it, please? Feedback appreciated :)
