# Validates that an attribute's value is not `nil`, but does allow blank, so is an alternative to
# `validate :attribute, presence: true` when empty should be allowed, but not `nil`.
#
# @example Validation declaration
# validates :attribute,
# non_nil: true
class NonNilValidator < ActiveModel::EachValidator
# Validates `value` is not `nil`. If `value` is `nil`, then the `:nil` error message is added to `attribute` on
# `model`.
#
# @param model [#errors] the ActiveModel or ActiveRecord being validated
# @param attribute [Symbol] the name of the attribute being validated whose value is `value`.
# @param value [Object, nil] the value of `attribute`.
# @return [void]
