From: naruse@... Date: 2021-02-16T07:13:44+00:00 Subject: [ruby-core:102522] [Ruby master Feature#17608] Compact and sum in one step Issue #17608 has been updated by naruse (Yui NARUSE). I think your code is actually `rel.pluck(:col).compact.sum`. It can be written as `rel.sum(:col)` https://api.rubyonrails.org/v6.1.0/classes/ActiveRecord/Calculations.html#method-i-sum ---------------------------------------- Feature #17608: Compact and sum in one step https://bugs.ruby-lang.org/issues/17608#change-90418 * Author: sawa (Tsuyoshi Sawada) * Status: Rejected * Priority: Normal ---------------------------------------- Many use cases of `Array#sum` are preceded with the `compact` method or are followed by a block to ensure the value is addable. ```ruby a = [1, nil, 2, 3] a.sum # !> TypeError a.compact.sum # => 6 a.sum{_1 || 0} # => 6 ``` I propose there should be a way to do that in one step. I request either of the following: A. Change the current behaviour to skip `nil`s. ```ruby a.sum # => 6 ``` B. `Array#filter_sum` method ```ruby a.filter_sum # => 6 ``` C. An option for `Array#sum` ```ruby a.sum(compact: true) # => 6 ``` -- https://bugs.ruby-lang.org/ Unsubscribe:
