Dr.Joe :
I want to save a new record to the table - Body. I use Spring Boot and HTML. so it looks in HTML:
<select id="bodiesList" multiple="multiple" class="selector">
<option th:each="b : ${bodies}"
th:value="${b.id}"
th:text="${b.name}"></option>
</select>
Controller:
@Controller
@RequestMapping("/general")
public class OrderController {
@Autowired
@Qualifier("orderServiceImpl")
private OrderService orderService;
@GetMapping(value = "/list")
public String get(Model theModel) {
theModel.addAttribute("orders", orderService.getOrders());
return "general/index";
}
@GetMapping(value = "/showFormForAdd")
public String add(Model theModel) {
Orders orders = new Orders();
List<Body> body = orderService.getBody();
theModel.addAttribute("bodies", body);
theModel.addAttribute("order", orders);
return "general/create-orders";
}
@PostMapping(value = "/saveOrders")
public String addOrders(@ModelAttribute("order") Orders orders, @RequestParam("picture") MultipartFile file) throws IOException {
orders = orderService.uploadOrders(orders, file);
orderService.save(orders);
return "redirect:/general/list";
}
}
but not in the database not in my column nothing is saved.
what needs to be fixed in my code?
Sumit :
Use th:field to send the values from your html page to your controller. try something like this -
<select th:field="*{body}" id="bodiesList" multiple="multiple" class="selector">
<option th:each="b : ${bodies}"
th:value="${b.id}"
th:text="${b.name}"></option>
</select>
And then capture this information on your controller after form submit (same as your're capturing the orders on your saveOrder controller.
