To create a Django model with two fields referencing the same model and ensuring that the combination of the two fields is unique, you can use the `unique_together` attribute in the model's Meta class.

Here's an example of how to achieve this:

Creating a Django Model with Two Fields Referencing the Same Model

In Django, you can create a model with two fields referencing the same model while ensuring uniqueness by using the `unique_together` attribute in the model's Meta class.

    
from django.db import models

class MyModel(models.Model):
    field1 = models.ForeignKey('self', on_delete=models.CASCADE)
    field2 = models.ForeignKey('self', on_delete=models.CASCADE)
    
    class Meta:
        unique_together = ('field1', 'field2')
    
    

In the above example, the `MyModel` model has two fields `field1` and `field2` that reference the same model itself. By setting `unique_together = ('field1', 'field2')` in the Meta class, you ensure that the combination of `field1` and `field2` will be unique together.

By following this approach, you can create a Django model with two fields referencing the same model while enforcing uniqueness for their combination.

```

By using the `unique_together` attribute in the model's Meta class, you can ensure that the combination of the two fields referencing the same model is unique in Django. This helps maintain data integrity and prevent duplicates in the database.
