peewee mysql how to execute 'insert many on duplicate key update'

See original GitHub issue

Hi Charles, how to execute sql command like

insert into table(ip,hostname,...)
values
('','',...)
('','',...)
('','',...)
...
on duplicate key update hostname=values(hostname),

upsert and on_conflict does not work

In [49]: result
Out[49]: 
[{'country': '',
  'guid': '122.225.227.21:80',
  'head': '',
  'hostname': '122.225.227.21',
  'ip': '122.225.227.21',
  'ipr': '',
  'port': 80,
  'protocol_type': 'tcp',
  'province': '',
  'server': '',
  'title': ''},
...]
In [50]: basicinfo_ip_finger.insert_many(result).on_conflict('REPLACE').execute()

ProgrammingError: (1064, "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'OR REPLACE INTO `basicinfo_ip_finger` (`ip`, `port`, `protocol_type`, `hostname`' at line 1")

please help, thanks

Peewee does support ON DUPLICATE KEY UPDATE:

http://docs.peewee-orm.com/en/latest/peewee/querying.html#upsert

MySQL supports upsert via the ON DUPLICATE KEY UPDATE clause. For example:

class User(Model):
    username = TextField(unique=True)
    last_login = DateTimeField(null=True)
    login_count = IntegerField()

# Insert a new user.
User.create(username='huey', login_count=0)

# Simulate the user logging in. The login count and timestamp will be
# either created or updated correctly.
now = datetime.now()
rowid = (User
         .insert(username='huey', last_login=now, login_count=1)
         .on_conflict(
             preserve=[User.last_login],  # Use the value we would have inserted.
             update={User.login_count: User.login_count + 1})
         .execute())
