simple-validations-rails

A simple set of validations I got tired of writing over and over and over again. Includes boolean, locale, and email validators.

Installation

Add this line to your application's Gemfile:

gem 'simple-validations-rails'

And then execute:

$ bundle

Or install it yourself as:

$ gem install simple-validations-rails

Usage

It's a set of validators...and is therefore used like other validators.

Boolean Validator

Validates that the value is boolean in nature.

# Allows only non-null booleanish values (most values that aren't nil are true - but in this case, nil is NOT false, and thus fails).
validates :allow_something, boolean: true

# Allows basically anything. Probably this is useless...
validates :preference_that_can_be_null, boolean: {allow_nil: true}

# Allows ONLY true or false.
validates :strict_preference, boolean: {strict: true}

# Allows ONLY true, false, or nil.
validates :strict_preference_that_can_be_null, boolean: {strict: true, allow_nil: true}

Locale Validator

Validates that the value is within the allowed locales for the application.

# Allows strings/symbols, checks against available locales.
validates :locale, locale: true

# Same as above, but nil is valid.
validates :locale, locale: {allow_nil: true}

Timezone Validator

Validates that the value is a valid timezone.

# Allows strings/symbols, checks against available locales.
validates :time_zone, timezone: true

# Same as above, but nil is valid.
validates :time_zone, timezone: {allow_nil: true}

Email Validator
