Module: Might::FilterPredicates

Defined in:
lib/might/filter_predicates.rb

Overview

Contains contains with all supported predicates You can register your own predicates. Predicates should perform on array or on singular value:

Might::FilterPredicates.register('includes', on: :array)
Might::FilterPredicates.register('is_upper_case', on: :value)
