Solve the following python programming problem given the following code:
@ genty_dataset (valid_deployment = genty_args (slaves_to_validate = ['slave_host_1', 'slave_host_2'], connected_slaves = ['slave_host_1', 'slave_host_2'], host_name_to_uid = {

    'slave_host_2' : 'host_2_id', 
}, is_valid = True), host_mismatch = genty_args (slaves_to_validate = ['slave_host_1', 'slave_host_2'], connected_slaves = ['slave_host_3', 'slave_host_2'], host_name_to_uid = { 
    'slave_host_2' : 'host_2_id', 
}, is_valid = False), number_of_slaves_not_match = genty_args (slaves_to_validate = ['slave_host_1'], connected_slaves = ['slave_host_1', 'slave_host_2'], host_name_to_uid = { 
    'slave_host_1' : 'host_1_id', 
}, is_valid = False), valid_deployment_different_host_names_with_same_host_id = genty_args (slaves_to_validate = ['slave_host_1', 'slave_host_2'], connected_slaves = ['slave_host_1_alias', 'slave_host_2'], host_name_to_uid = { 
    'slave_host_1' : 'host_1_id', 
    'slave_host_1_alias' : 'host_1_id', 
    'slave_host_2' : 'host_2_id', 
}, is_valid = True)) 
def test_validate_deployment_checks_each_slave_is_connected(self, slaves_to_validate, connected_slaves, host_name_to_uid, is_valid) : 
    def get_host_id(host) : 
        if (host in host_name_to_uid) : 
            return host_name_to_uid [host] 
else : 
            return str (uuid.uuid4 ()) 
self.patch ('app.util.network.Network.get_host_id', new = host_name_to_uid) 
    deploy_subcommand = DeploySubcommand ()

            validate ()

        validate () 

    
    

    Fix the buggy line: self.patch ('app.util.network.Network.get_host_id', new = host_name_to_uid)
