What are some examples of relations in TypeORM?
An example of an AI chatbot conversation about TypeORM relations and how to implement them.
Can you explain the different types of relations in TypeORM?
Sure! TypeORM supports several types of relations: One-to-One, One-to-Many, Many-to-One, and Many-to-Many.
Can you give me an example of a One-to-Many relation?
Absolutely! In a One-to-Many relation, for instance, a User can have many Posts. You would define it like this in your entities.
How do I set up a Many-to-Many relation?
To set up a Many-to-Many relation, you need to create a join table. For example, if you have Users and Roles, you can create a UserRoles join table.
What about cascading options in these relations?
Cascading options allow you to automatically propagate changes. For example, if you delete a User, you can set it to also delete all related Posts.
