What is the difference between one-to-many and one-to-one relationships in Django?
An example of an AI chatbot conversation about Django relationships: one-to-many vs one-to-one.
What is the difference between one-to-many and one-to-one relationships in Django?
In Django, a one-to-many relationship means one record in a model can be related to multiple records in another model. For example, a single author can write multiple books.
Can you give me an example of how to implement a one-to-many relationship in Django?
Sure! You can use a ForeignKey field in your model. For instance, in a Book model, you would have a ForeignKey to the Author model.
What about one-to-one relationships? How do they differ?
A one-to-one relationship means each record in one model corresponds to exactly one record in another model. You can implement this using OneToOneField in Django.
When should I use one-to-many vs one-to-one relationships?
Use one-to-many when a single record can relate to multiple records, and one-to-one when each record should only relate to one other record.
