After spending hours trying to figure it out by myself I was about to give up on this topic, but your video saved me! Thank you so much!

Awesome video my friend ! I saw this topic in many others videos (some of the them with cost) and you've been the only that explains it in a practical and simple way. My English is not good but I underestood you clearly. Thanks a lot, you have a new suscriptor !

can't express in words how much I want to thank you. I finally understood how mapping is done. this things has been haunting me for a few years since I learned sql. thank you very much

Awesome video. Searched a lot to understand this concept. Finally I got it. Thank you.

You couldn't be clearer than this! Thanks a lot!

as always, great tutorial, thank you man

Best Best Best Tutorial and way to explain is amazing, bro I am literally speechless. Bro, I owe you this one.

The way your presented this is awesome! Thanks a lot!

You are hell of a teacher my friend

Thanks, this lesson was right in time!!

Thanks a lot. Finally, so many things got cleared. With one to many, always an additional table gets created. In sql, we can simply add fk, this is achieved in hibernate from many-to-one side. Using mapped-by, we can tell one-to-many side entity to not worry, and only let many-to-one side entity handle the relationship. This video is gold, you may really be a tech pro afterall, like your user-name suggests. Cheers.

Thanks for video. I'm studying on a project. But when i try to do onetomany mapping, the foreignKeys are not created at Database. In your example this foreign key is DepartmentId. Have you any advice ?

Awesome man...keep it up

Do I understand correctly that if there are two entities with a One-to-Many relationship, such as Employee and EmployeePhones. Then you need to receive such data on the server in DTO with one call, but with two separate json? And write down one by one: first the employee, get the ID from the saved employee, and then we record the phones using this ID for communication.

Yes, if you must have two separate json files. But why do you need two separate json?

That's nice explanation, but i want something like; department{ id: ... name: ...... students: { id: ..... name: .... } } That is , in your case the student have department_id, but what i want to put the student_id into the department table. like i try to show in the above json format. Thanks in advance :)

I get your point but we need to be careful with this so we avoid infinite recursion. How to do this is explained here kzread.info/dash/bejne/n52il5dvc5qaac4.html

Can u provide GitHub link?

CoolDB🤣😂

Thanks for the explanation, that was really helpful. I still have a question. If you post a department with a Student with POST. Does the Student Objekte is automatically added to the students table and is accessible with student/:Id?

@@SergiuIoan99 Hi Ya if got an answer for that. If you Post a department you dont create a new Student you just pass the reference of the existing student that you want to add to the department. So Step one you create a Student step two you create a Department and pass the reference in the JSON object of Department. Reference is the Link students/student/id. And Spring will do the rest. I hope I could answer your question. If not tell me i will try to explain it again :)
