Class Method Details

.setup_after ⇒ Object

Models opt in to ActiveRecordOptional individually via include Errgonomic::Rails::ActiveRecordOptional.

# File 'lib/errgonomic/rails.rb', line 22

def self.setup_after; end

.setup_before ⇒ Object

We provide helper class methods, like delegate_optional, which need to be included into ActiveRecord::Base before any models are evaluated.

def self.setup_before
  ActiveRecord::Base.include(Errgonomic::Rails::ActiveRecordDelegateOptional)
end

.unwrap_options(value) ⇒ Object

Unwrap Options in a query condition, reaching one level into an array so a list of Options binds like a list of values.
