+# 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
+#

+  def validate_each(record, attribute, value)
