# ActiveRecord::Validations

### Public Instance Methods

save(options={}) click to toggle source

The validation process on save can be skipped by passing false. The regular Base#save method is replaced with this when the validations module is mixed in, which it is by default.

    # File lib/active_record/validations.rb, line 42
    def save(options={})
      perform_validations(options) ? super : false
    end

save!(options={}) click to toggle source

Attempts to save the record just like Base#save but will raise a RecordInvalid exception instead of returning false if the record is not valid.

    # File lib/active_record/validations.rb, line 48
    def save!(options={})
      perform_validations(options) ? super : raise(RecordInvalid.new(self))
    end

valid?(context = nil) click to toggle source

Runs all the specified validations and returns true if no errors were added otherwise false.

    # File lib/active_record/validations.rb, line 53
    def valid?(context = nil)
      context ||= (new_record? ? :create : :update)
      output = super(context)

      deprecated_callback_method(:validate)
      deprecated_callback_method(:"validate_on_#{context}")

      errors.empty? && output
    end

### Protected Instance Methods

perform_validations(options={}) click to toggle source

    # File lib/active_record/validations.rb, line 65
    def perform_validations(options={})
      perform_validation = case options
      when Hash
        options[:validate] != false
      else
        ActiveSupport::Deprecation.warn "save(#{options}) is deprecated, please give save(:validate => #{options}) instead", caller
        options
      end

      if perform_validation
        valid?(options.is_a?(Hash) ? options[:context] : nil)
      else
        true
      end
    end
