At guides.rubyonrails.org I read about the possibilities of
find_in_batches. However I cannot find this option anywhere in the API
documentation (api.rubyonrails.org).
My question: where should I look for the documentation of this
command?
If this function (find_in_batches) is depreciated, what alternative is
there? Same goes for the function find_each... in the current version
of Rails they are still working, but for how long?
