I have encountered a situation where I am utilizing an entity setup similar to the one explained in this resource. The problem arises when I try to remove entries from post.postToCategories. Instead of deleting the entire row, TypeORM sets one side of the relation to null, essentially causing a detachment issue.
How can I ensure the complete deletion of the row?
Even though it may seem belated, I've decided to leave the resolution here for anyone else who may come across a similar issue involving deleting connections for many-to-many relationships that involve custom properties.
Imagine there are two entities, User and Post, with a many-to-many connection entity called UserPost that includes custom properties:
const user_post_connections: UserPosts[] = await this.userPostRepository.find(
{
where: {
user: user,
},
},
);
if (user_post_connections?.length) {
await this.userPostRepository.remove(user_post_connections);
}
DISCLAIMER: This solution is specific to the scenario outlined in this question, referencing this setup.
To resolve this issue, you can utilize the orphanedRowAction parameter. In the scenario where you have a join table named PostConnections connecting a user and a post, you can specify orphanedRowAction: 'delete' for each ManyToOne relationship as shown below:
@ManyToOne(
() => User,
(user) => user.postConnections,
{ orphanedRowAction: 'delete' },
)
user: User;
@ManyToOne(
() => Post,
(post) => post.postConnections,
{ orphanedRowAction: 'delete' },
)
post: Post;
