Teraz pokaże Wam relację jaka wystepuje miedzy klasami ,metodę controllera oraz moją metodę ajax.
@Entity
@Table(name = "Samochody")
public class CarBD {
@Setter
@Getter
@JsonIgnore
@OneToMany(fetch = FetchType.LAZY,mappedBy = "car",cascade = CascadeType.ALL)
private List<ExchangeBD> exchangeList = new ArrayList<>();
}
--------------------------------------------------
@Entity
@Table(name = "Wymiany")
public class ExchangeBD {
@Setter
@Getter
@ManyToOne
@JoinColumn(name = "car")
@NotNull
private CarBD car;
}
METODA CONTROLLERA --------------------------------------------------
@RequestMapping(value = "addExchange",method = RequestMethod.POST,produces = "application/json")
public ResponseEntity<ExchangeBD> addExchange(@RequestBody ExchangeBD exchange){
exchangeService.saveOrUpdate(exchange);
HttpStatus httpStatus = exchange !=null ? HttpStatus.CREATED : HttpStatus.CONFLICT;
return new ResponseEntity<ExchangeBD>(exchange,httpStatus);
}
METODA AJAX--------------------------------------------------
var saveExchange = function(){
var exchange = {
"car": {'id':parseInt($('#carListSelect').get(0).id,10)},
"exchangeDate": $('#exchangeDateInput').val(),
"exchangePrice": $('#exchangePriceInput').val(),
"exchangeDescription": $('#exchangeDescriptionInput').val(),
"place": {'id':parseInt($('#placeListSelect').get(0).id,10)}
};
$.ajax({
url: 'exchange/addExchange',
type: 'POST',
contentType:"application/json",
data: JSON.stringify(exchange),
success: function () {
alert("Dodano nową wymianę");
$('#exchangeDateInput').val('');
$('#exchangePriceInput').val('');
$('#exchangeDescriptionInput').val('');
},
error: function (jqxhr, textStatus, error) {
var err = textStatus + ", " + error;
console.log( "Request Failed: " + err );
}
});
};
