How to set delete and inverse delete for OTM

Support
#1

I’m trying to set delete rules in Studio, but keep running into constraint violations. Specifically, I have a one-to-many relationship between a visit table (one) and problem table (many). Each side has a foreign key to the other.

When a visit is deleted, I want all the problems to also be deleted. How do I set the “on delete” and “on inverse delete” rules for this? I’ve tried many combinations, but keep getting an FK constraint violation on the visit table side.

Thanks
Eric

Hi Eric,
>I have a one-to-many relationship between a visit table (one) and problem table (many). Each side has a foreign key to the other.
Probably you have a foreign key (a column) in in Problem table and an inverse attribute (mappedBy, no column) in Visit. So you should annotate Visit.problems attribute with @OnDelete(CASCADE). Also, keep in mind that OnDelete rules take effect only on soft deleted entities. If your entities do not implement SoftDelete, define cascade deletion on database layer in foreign keys.
