MY Code looks like so

from djongo import models
class pass_details(models.Model):
    pass_no=models.CharField( max_length=20)
    class Meta:
        abstract = True
class student(models.Model):
    pass_details=models.EmbeddedField(model_container=pass_details, null=True)
    usn=models.CharField(max_length=10)
    name=models.CharField(max_length=20)
    objects = models.DjongoManager()

Are you sure you are loading your models in:pass_details=models.EmbeddedField(model_container=pass_details, null=True) It seems to me that the null = True is preventing you to load your model. You can have a look again on the documentation on how to specify the parameters here: https://djongo.readthedocs.io/docs/embedded-model-field/
