# BytesizeValidator
|
|
#
|
|
# Custom validator for verifying that bytesize of a field doesn't exceed the specified limit.
|
|
# It is different from Rails length validator because it takes .bytesize into account instead of .size/.length
|
|
#
|
|
# Example:
|
|
#
|
|
# class Snippet < ActiveRecord::Base
|
|
# validates :content, bytesize: { maximum: -> { Gitlab::CurrentSettings.snippet_size_limit } }
|
|
# end
|
|
#
|
|
# Configuration options:
|
|
# * <tt>maximum</tt> - Proc that evaluates the bytesize limit that cannot be exceeded
|
|
class BytesizeValidator < ActiveModel::EachValidator
