When Active Record calls `set_callback` inside `after_commit`, [these lines of code](https://github.com/rails/rails/blob/master/activerecord/lib/active_record/transactions.rb#L276) pass an **array** of methods as the `:if` condition: ```ruby options[:if] = Array(options[:if]) options[:if] << "transaction_include_any_action?(#{fire_on})" ``` That made me realize that anyone could pass an **array** of `:if` and `:unless` conditions to `set_callback`, since Active Support transforms these conditions into an array anyways in [these lines of code](https://github.com/rails/rails/blob/master/activesupport/lib/active_support/callbacks.rb#L365): ```ruby @if = Array(options[:if]) @unless = Array(options[:unless]) ``` Long story short, this commit updates the documentation of the `set_callback` method to explain that arrays are also accepted. It also replaces +false+ and +true+ with false and true, since any _falsey_ or _truthy_ value will work. [ci skip] |
