I am trying to use use_cursor with eager,
but use_cursor requires to use each,
which didn't work well with eager. Any advise?
Thanks!
For now, I am doing something like this to
simulate it:
query.use_cursor(:rows_per_fetch => 100).each_slice(100) do |records|
assocs = Assoication.where(:id => records.map(&:association_id)).all
records.each do |r|
r.association = assocs.find{ |a| a.id == r.association_id }
end
end
It would be great if there's a better way to do this.
p.s. use_cursor:
