Ruby – Rails Model: Validates_Unique Ness_OF Will not delete the endless space before a unique check? Isn’t the front guide?

class Person
 before_validation :strip_blanks

 protected

 def strip_blanks
 self.name = self.name.strip
 end
end

Suppose I implement validates_uniqueness_of on the username. If the name’maddy’ is already Exists, then it will accept the value’maddy’ as the only value instead of’maddy’. It should remove the spaces on both sides. How can there be this behavior?

class Person
 before_validation :strip_blanks

 protected

 def strip_blanks
 self .name = self.name.strip
 end
end

The source of this snippet contains some discussion as to why this is not the default Rails behavior. http://www.ruby -forum.com/topic/166426
