Solve the following python programming problem given the following code:
def callback(self, scanner, name, view) : 
    config = scanner.config.with_package (self.module) 
    route_path = ''.join ([scanner.state.route_path, ('' if self.state.route_path.endswith ('/') else '/'), self.name]) 
    route_name = ('%s-%s' % (self.state.route_name, self.name)) 
    self.state.add_controller (self.name, view, self.request_method) 
    if (not self._must_register_route (config, route_name)) : 
        config.add_route (route_name, route_path, factory = self.state.resource_class) 
        def opt(resource, request) : 
            return default_options_view (resource, request, [self.request_method]) 
config.add_view (opt, route_name = route_name, request_method = 'OPTIONS', permission = NO_PERMISSION_REQUIRED) 
        config.add_view (unsupported_method_view, route_name = route_name, renderer = 'json') 
config.add_view (view, route_name = route_name, request_method = self.request_method, context = self.state.resource_class, ** self.view_arguments) 

    
    

    Fix the buggy line: route_path = ''.join ([scanner.state.route_path, ('' if self.state.route_path.endswith ('/') else '/'), self.name])

#Here is Python code to fix the buggy line: route_path = ''.

route_path = ''.join ([self.state.route_path, ('' if self.state.route_path.endswith ('/') else '/'), self.name])
