# ProjectPathValidator
#
# Custom validator for GitLab project path values.
#
# Values are checked for formatting and exclusion from a list of reserved path
# names.
class ProjectPathValidator < ActiveModel::EachValidator
# All project routes with wildcard argument must be listed here.
# Otherwise it can lead to routing issues when route considered as project name.
#
# Example:
# /group/project/tree/deploy_keys
#
# without tree as reserved name routing can match 'group/project' as group name,
# 'tree' as project name and 'deploy_keys' as route.
