# frozen_string_literal: true
# WildcardBranchFilterValidator
#
# Custom validator for wildcard branch filter. Squishes whitespace and ignores
# empty string. This only checks that a string is a valid wildcard git branch
# like "feature/login" and "feature/*". It doesn't check whether a branch already
# exists.
#
# Example:
#
# class Webhook < ActiveRecord::Base
# validates :push_events_branch_filter, "web_hooks/wildcard_branch_filter": true
# end
#
module WebHooks
class WildcardBranchFilterValidator < ActiveModel::EachValidator
def validate_each(record, attribute, value)
value.squish! unless value.nil?
return unless value.present?
value_without_wildcards = value.tr('*', 'x')
unless Gitlab::GitRefValidator.validate(value_without_wildcards)
record.errors.add(attribute, "is not a valid branch name")
end
return if value.length <= 4000
record.errors.add(attribute, "is longer than the allowed length of 4000 characters.")
end
end
end
