- go to section 4 to see how to register channel handlers (a Vue - Django async communication tool) in urls.
3. migrate
- no need to makemigrations and migrate for valar, valar will auto migration
4. how to register a channel handler for Morghulis async methods
4.1 create a handler
4.2 create a dict (e.g. using the name 'channel_mapping') to save your handler
- I'd like to put it in the root urls.py, you can put it anywhere
4.3 register the channel_mapping in the settings.py
4.4 you can copy the following codes to your urls.py
5. create an orm model extends the AbstractUser class, enable the authentication of Valar
class User(AbstractUser):
"""
any fields you want
"""
description = models.TextField(null=True, verbose_name='备注')
