inserting a foreign key in child table it showing null everytime - mysql

Question

I am inserting a foreign key in a child table using a #OnetoMany relationship between parent and medicine. One parent has many medicines and it shows me null.
I have done many searches for my problem and I have tried every possible solution, but it's not working.

Answer 1

solved, I got the mistake that i didn't set the medicine in the patient,
"patient.setMedicines(patientBean.getMedicines());" just add this one in my code and my code is working properly.
