Adding attributes into Django Model's Meta class

I don't know about elegant, but one pragmatic way is:

import django.db.models.options as optionsoptions.DEFAULT_NAMES = options.DEFAULT_NAMES + ('schema',)

Obviously, this would break if Django ever added a 'schema' attribute of its own. But hey, it's a thought...you could always pick an attribute name which is less likely to clash.

Not a direct answer, but I did not like the idea of adding it in every model where I need it to the options, so I did:

class MyModel(models.Model):        class Meta:        ordering = ["myfield"]    class MyPrefixMeta:        my_value = "Abc"

You could even put this to a abstract model and validate the set class properties in __init__ function or do things like adding a _myprefix_meta property to the model. So you had your own meta class.

This works for me for setting extra fields in meta for a Django model.

class Vendor(CustomModel):    def __init__(self, *args, **kwargs):        cls = self.__class__        meta = getattr(cls, '_meta', None)        setattr(meta, 'exclude_logging', ["otp", "is_otp_verified"])        super().__init__(*args, **kwargs)

This exclude_logging field can be accessed as below.

class CustomModel(models.Model):    objects = UpdateManager()    class Meta:        abstract = True    def save(self, *args, **kwargs):        print(self._meta.exclude_logging)

I hope this solves the problem.
