yeah it will get saved) but findUserById returns user with 0 sized posts for some reason

dan1st•4mo ago

Can you try findAll()?

KoblížkáčOP•4mo ago

where exactly?

dan1st•4mo ago

Can you show your repository?

public interface PostRepository extends JpaRepository<Post, Long> {

public interface PostRepository extends JpaRepository<Post, Long> {

dan1st•4mo ago

that should contain a findAll() method Can you try calling thatIn your /posts endpoint, can you call that and print the result?

KoblížkáčOP•4mo ago

yeah it extends JpaRepository, should i just run it on debugger? where though oh

dan1st•4mo ago

yeah or using a debugger works as well

KoblížkáčOP•4mo ago

right

KoblížkáčOP•4mo ago

i get

KoblížkáčOP•4mo ago

like this

KoblížkáčOP•4mo ago

i was wondering if maybe it could be by the configuration of the posts column?

dan1st•4mo ago

is user the correct user? How are you inserting it? Can you show the other side of the 1:n relation?

KoblížkáčOP•4mo ago

like this

KoblížkáčOP•4mo ago

post side of the relation is:

dan1st•4mo ago

in here, is user the user with ID 1?

KoblížkáčOP•4mo ago

yeah

KoblížkáčOP•4mo ago

you can see posts.size = 0 for some reason yeah ithink why the order of saving is wrong inside addpost any idea how to do it properly?

dan1st•4mo ago

try that:

post.setUser(user);
user.getPosts().add(post);
postRepository.save(post);
userRepository.save(user);

post.setUser(user);
user.getPosts().add(post);
postRepository.save(post);
userRepository.save(user);

maybe switch the last two lines

KoblížkáčOP•4mo ago

nope smh still empty array

dan1st•4mo ago

Does both happen in the same thread?

KoblížkáčOP•4mo ago

well im not doing any parallel stuff, soo how can i check?

dan1st•4mo ago

actually I think this shouldn't matter since you get a symptom of it being changed ohhhhhh

KoblížkáčOP•4mo ago

i mean it should work

dan1st•4mo ago

lol

KoblížkáčOP•4mo ago

hm?

dan1st•4mo ago

try using a List instead of a Set or make sure Post#hashCode and Post#equals don't include the ID or do user.setPosts(new HashSet<>(user.getPosts())); before saving the user

KoblížkáčOP•4mo ago

okay

dan1st•4mo ago

but if you want to avoid difficulties, don't persist Sets with JPA

KoblížkáčOP•4mo ago

okay

dan1st•4mo ago

Does that work?

KoblížkáčOP•4mo ago

uno momento nope im clueless at this point lol

dan1st•4mo ago

Can you show your code?
