SmsValidation

This gem does not send SMS messages. It just makes sure the arguments are valid.

What are valid arguments for an SMS message?

  • Phone number: 10 digits, does not begin with 0 or 1
  • Message: Not longer than 160 characters.

What if my message is longer than 160 characters?

You have 3 choices:

  • Truncate the message to the first 160 characters
  • Split it into multiple messages
  • Raise a SmsValidation::Sms::MessageTooLongError error

You can configure at any time using:

SmsValidation.configuration.on_message_too_long = :truncate # or :split or :raise_error

It defaults to :raise_error

Installation

Add this line to your application's Gemfile:

gem 'sms_validation'

And then execute:

$ bundle

Or install it yourself as:

$ gem install sms_validation

Usage

Configuration

SmsValidation.configure do |config|
  config.on_message_too_long = :truncate # or :split or :raise_error
  config.logger = ::Logger.new(STDOUT) # Defaults to ::Rails.logger if ::Rails.logger is defined

  # This DOES NOT change the log_level of the logger--use `config.logger.level = :debug` for that
  # This DOES determine the log level at which messages should be logged.
  # This provides a convenient way to toggle whether this gem should log without interfering with the log level of others processes sharing the logger.
  # For instance, if you're using Rails, you probably don't want to set the log_level to DEBUG, because then ActiveRecord will log every query.
  # But you may still want SmsValidation to log everything it does.
  config.log_at :info

  # OR you may want SmsValidation to log only when you're logging all other DEBUG messages.
  config.log_at :debug
end
