jukenduit :
I am developing a small cms and I am using spring data jpa to do my database stuff.
When I add a new page, I want to make sure the slug doesn't already exist, for that purpose I added a method to my repository:
public interface PageRepository extends JpaRepository<Page, Integer> {
Page findBySlug(String slug);
}
That works fine when adding.
However when editing a page, I want to check that the slug doesn't already exist but NOT for the current page, how can I do that? I guess I could somehow pass the current row id or something like that, but how would I do that?

You can write
Page findBySlugAndIdNot(String slug,Long id)
where id is name of your identifier in entity with proper type. Look at documentation
