How to Define Two Foreign Keys as Unique Together in Django
In Django, you can define two foreign keys to the same model as unique together by using the UniqueConstraint option in the Meta class of the model.
from django.db import models
class MyModel(models.Model):
first_foreign_key = models.ForeignKey('RelatedModel', on_delete=models.CASCADE)
second_foreign_key = models.ForeignKey('RelatedModel', on_delete=models.CASCADE)
class Meta:
constraints = [
models.UniqueConstraint(fields=['first_foreign_key', 'second_foreign_key'], name='unique_together_constraint')
]
By adding the UniqueConstraint with the fields of the two foreign keys in the Meta class of the model, you ensure that the combination of these two foreign keys will be unique together.
```
By following this approach, you can easily define two foreign keys to the same model as unique together in Django, which can be beneficial in various scenarios while maintaining data integrity and consistency in your database.
