I have a Student Class



I also have a School class




I'm posting a JSON post request, and everything is posting except for foreign key for the school ID.  It comes up NULL no matter how I insert it.




   {
     
       "studentId": "S2762",
        "school":{
            "id":1
        },
       "firstName": "David",
       "lastName": "Miller",
       "restrictedReason": "Not Applicable ",
       "ticketNumber":"7743",
       "restricted": false
   
   }


How do I get it to post the school ID as 1 and not as NULL?

Can you show us your code how you set up the relationship between the student and school?

I changed @JsonIgnore to @JsonBackReference and it seemed to fix the problem for now.
 
I've got no option but to sell you all for scientific experiments. Or a tiny ad:
