Django UUID Field does not autocreate with new entry-CodePudding

I just added a new model where I want to use a UUID for the first time. I run Django 3.1.3 on python 3.8.10.

Found some questions about this and I am quite certain I did it according to those suggestions. However, when I add an entry to that model (in phpmyadmin web-surface) the UUID is not being added, it just stays empty. However when I create an other one I get the error, that the UUID Field is not allowed to be the same as somewhere else (both empty) which means at least the unique=True does work.

Another thing to mention is, when I create the field using VSCode, normally those fieldnames are being auto-completed, however it is not the case with this one. Thought this might give you a hint what is going on.

My model looks like this:

from django.db import models
import uuid


class MQTTTable(models.Model):
    
    uuid = models.UUIDField(primary_key = True, default = uuid.uuid4, editable = False, unique = True)
    description = models.CharField(max_length= 100, default = None)
    clientID = models.CharField(max_length = 50, default = None)
    mastertopic = models.CharField(max_length = 200, default = None)

The default = uuid.uuid4 is a Django ORM default, it's not something the database will do for you like the auto incrementing for ID. So if you add an entry via the phpmyadmin, it will not set the uuid field.

change default = uuid.uuid4 to default = uuid.uuid4()
