save(options={})

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 activerecord/lib/active_record/validations.rb, line 42
42:     def save(options={})
43:       perform_validations(options) ? super : false
44:     end
save!(options={})

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.

48:     def save!(options={})
49:       perform_validations(options) ? super : raise(RecordInvalid.new(self))
50:     end
valid?(context = nil)

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