How to update reference object in Spring-data rest?

Question

Example: class Course and Teacher having many-to-one relationship, how to change teacher for a certain course via Spring-data rest?

GET http         


        

Answer 1

Using httpie PATCH instead of PUT works for me:

http PATCH :7070/study-spring-data/course/2 teacher="http://localhost:7070/study-spring-data/teacher/2"

Again, this does not work with PUT.

Answer 2

I think you should have to check the Cascading for Course. Because if you are updating the course , then it should update your teacher also, if Cascading update or All is to be assigned for your course.

Answer 3

How about something like this:

curl -v -X PUT -H "Content-Type: text/uri-list" \
     -d "http://localhost:7070/study-spring-data/teacher/1" \
     http://localhost:7070/study-spring-data/course/123/teacher

This is a way suggested by O'Reilly's Spring Data book.
