Reusing a custom "getter" in ruby

How can I make something like this...more compact?

def token 
  if authorized?
    return t.token
  else
    raise Error('unauthorized!')
  end
end

def secret
  if authorized?
    return t.secret
  else开发者_JAVA技巧
    raise Error('unauthorized!')
  end
end

Feels like way too much re-use at the moment.

Add a filter that will run before the token or secret methods are called.

before_filter :check_authorization, :only => [ :token, :secret ]

Then add a method that will check if user is authorized,

def check_authorization
    if !authorized?
        raise DropboxError('User is not authorized')
    end
end

def token
    @token
end

def secret
    @secret
end

If token and secret are already properties of your model defined with :attr_accessor or something like that, you could eliminate the token and secret methods altogether as they are simple getters with no logic.
