You'd rather update the setter instead of polluting your model with callbacks:
def username=(value)
self[:username] = value.to_s.strip
end
Btw, I prefer squish

I'm trying to strip
the whitespaces of the variable Username
in my User Model.
I'm using
before_save do
self.username.strip!
end
but it doesn't seem to work, am i missing something ?

If you want to remove only leading and trailing white space you can use .strip!
But as you said:

I think actually you want to remove all spaces following should do:
.gsub(/\s+/, "")
EDIT:
Oh yes, You can also use Rail's built-in method squish()
