* Add ActiveRecord::Relation#in_batchesSina Siadat2015-08-071-2/+230
| | | | | | | | | | | | | | | | | `in_batches` yields Relation objects if a block is given, otherwise it returns an instance of `BatchEnumerator`. The existing `find_each` and `find_in_batches` methods work with batches of records. The new API allows working with relation batches as well. Examples: Person.in_batches.each_record(&:party_all_night!) Person.in_batches.update_all(awesome: true) Person.in_batches.delete_all Person.in_batches.map do |relation| relation.delete_all sleep 10 # Throttles the delete queries end

* Remove ActiveRecord::Base.to_aJon Leighton2012-08-031-1/+1
| | | | | On reflection, it seems like a bit of a weird method to have on ActiveRecord::Base, and it shouldn't be needed most of the time anyway.
* ActiveRecord::Base.all returns a Relation.Jon Leighton2012-07-271-1/+1
| | | | | | | | | | | Previously it returned an Array. If you want an array, call e.g. `Post.to_a` rather than `Post.all`. This is more explicit. In most cases this should not break existing code, since Relations use method_missing to delegate unknown methods to #to_a anyway.

| * Stop find_in_batches using the records after yielding.Caius Durling2011-06-211-0/+16
| | | | | | | | | | | | Currently if the code that calls .find_in_batches modifies the yielded array in place then .find_in_batches can enter an infinite loop searching with ruby object ids in the database instead of the primary key of records in the database. This happens because it naively assumes the yielded array hasn't been modified before calling #id on the last object in the array. And ruby (1.8 at least) alias' #id to #object_id so an integer is still returned no matter what the last object is. By moving finding the #id of the last object before yielding the array it means the calling code can do whatever it wants to the array in terms of modifying it in place, and .find_in_batches doesn't care.
* | Make `ActiveRecord::Batches#find_each` to not return `self`.knapo2011-07-071-0/+7
| | | | | | | | This caused that `find_each` was producing extra db call taking all the records from db, and was less efficient than `ActiveRecord::Base#all`.

You can also run tests directly via the command line, e.g. ruby path/to/test.rb (no rake needed, uses default db connection from test/config.yml). This will help us fix the CI by enabling us to isolate the different Rails versions to different databases.
