Solve the following python programming problem given the following code:
def connect(self, configname = None) : 
    'Connect to a database based upon its `nickname`.

        See ipydb.magic.connect() for details.
        ' 
    (default, configs) = engine.getconfigs () 
    success = False 
    def available() : 
        print (self.connect.__doc__) 
        print (('Available connection nicknames: %s' % ' '.join (sorted (configs.keys ())))) 
if (not configname) : 
        available () 
else : 
        if (configname not in configs) : 
            print (('Config `%s` not found. ' % configname)) 
            available () 
else : 
            config = configs [configname] 
            connect_args = { 
                
} 
            success = self.connect_url (engine.make_connection_url (available), connect_args) 
            if success : 
                self.nickname = configname 
return success 

    
    

    Fix the buggy line: success = self.connect_url (engine.make_connection_url (available), connect_args)
assistant
#Here is Python program to fix the buggy line: success = self.

success = self.connect_url (engine.make_connection_url (config), connect_args)
