java - Setting value of different JSON key to field Play framework -

i creating rest service in play framework , have route reads json request. json in format:

{ "email":"test@test.com", "password":"pw", "address":{ "city":"cityname", "country":"countryname"} } 

then use user = json.fromjson(json, user.class); parse json user class. in database, have tables 1 one relation like:

user:

email varchar, name string 

address:

email varchar, city varchar, address varchar 

where email foreign key.

since json receive has 5 values, when play framework saves new record database,in address saves city , address, , email field saved null. , later on can not retrieve value of address item of related user record since foreign key connects them saved null. (these sql queries: )

is there annotation or other way how can use email value json email value in address table?

here how wrote model classes:

@entity @table(name = "user") public class user extends model{     @id     @column(length = 80)     private string email;     @column(length = 100)     private string password;     @onetoone(cascade =  cascadetype.all, mappedby = "user")     private address address; }  @entity @table(name = address public class address extends model{     @onetoone()     @joincolumn(name = "email")     private user user;      @column(length = 100)     private string city;     @column(length = 100)     private string country; } 

why don't try saving address first, later when object address managed orm set object address object user , persist object user.

something this:

• parse json user object
• get address user object parsed.
• persist address object
• set address object user object again
• persist user object.

i hope help.
