#update_column(s) skips callbacks (which is useful), but it doesn't change the updated_at field on the record by default (which we should be doing in these cases).
This change is made in Spree 2.2 here: b367c629ce
:amount is a database field in these cases, as opposed to a method that returns a computed result. Calling `.sum(:amount)` is much more efficient here as it computes the sum at database level, as opposed to `.map(&:amount).sum`, which would fetch and instanciate all the objects first, and then sum the amounts after.
DEPRECATION WARNING: `#deliver` is deprecated and will be removed in Rails 5. Use `#deliver_now` to deliver immediately or `#deliver_later` to deliver through Active Job.
Also add tests for each of the different report types. I didn't make these JavaScript tests because not sure that is necessary and they would be slower.
Before the date and distributor filters would have no effect. This is because the BulkCoopReport is still generated using an older style method, and isn't generated using the newer method like in the EnterpriseFeeSummaryReport. This older style report expects to receive a :q parameter but it actually received the newer style :report parameter so the filters were not being applied.
This keeps the newer style report params but converts them, after they are authorised as safe, into the older style in the controller.
For the BulkCoop report to speed up. We move from an output like
