# UrlValidator
|
|
#
|
|
# Custom validator for URLs.
|
|
#
|
|
# By default, only URLs for the HTTP(S) protocols will be considered valid.
|
|
# Provide a `:protocols` option to configure accepted protocols.
|
|
#
|
|
# Also, this validator can help you validate urls with placeholders inside.
|
|
# Usually, if you have a url like 'http://www.example.com/%{project_path}' the
|
|
# URI parser will reject that URL format. Provide a `:placeholder_regex` option
|
|
# to configure accepted placeholders.
|
|
#
|
|
# Example:
|
|
#
|
|
# class User < ActiveRecord::Base
|
|
# validates :personal_url, url: true
|
|
#
|
|
# validates :ftp_url, url: { protocols: %w(ftp) }
|
|
#
|
|
# validates :git_url, url: { protocols: %w(http https ssh git) }
|
|
#
|
|
# validates :placeholder_url, url: { placeholder_regex: /(project_path|project_id|default_branch)/ }
|
|
# end
|
|
#
|
|
