h4(#validations_overview-errors). +errors[]+
To verify whether or not a particular attribute of an object is valid, you can use +errors[:attribute]+ that returns an array with all attribute errors, when there are no errors on the specified attribute, an empty array is returned.
To verify whether or not a particular attribute of an object is valid, you can use +errors[:attribute]+. It returns an array of all the errors for +:attribue+. If there are no errors on the specified attribute, an empty array is returned.
This method is only useful _after_ validations have been run, because it only inspects the errors collection and does not trigger validations itself. It's different from the +ActiveRecord::Base#invalid?+ method explained above because it doesn't verify the validity of the object as a whole. It only checks to see whether there are errors found on an individual attribute of the object.
