@Controller
@RequestMapping("/admin/types")
public class TypeController {

    @Autowired
    private ITypeService typeService;

    @GetMapping
    public String list(@PageableDefault(size = 5,sort = {"id"},direction = Sort.Direction.DESC) Pageable pageable, Model model){
        Page<Type> page = typeService.listType(pageable);
        model.addAttribute("page",page);
        return "admin/types";
    }

    //@{/admin/types/{id}/delete(id=${type.id})}
    @GetMapping("{id}/delete")
    public String delete(@PathVariable Long id){
        typeService.deleteType(id);
        return "redirect:/admin/types";
    }

    @GetMapping("input")
    public String input(Model model){
        model.addAttribute("type",new Type());
        return "admin/types-input";
    }

    @PostMapping("add")
    public String add(Type type){
        typeService.addType(type);
        return "redirect:/admin/types";
    }

    @GetMapping("{id}/toUpdate")
    public String toUpdate(@PathVariable Long id, Model model, RedirectAttributes attributes){
        Type type=typeService.getType(id);
        model.addAttribute("type",type);
        return "admin/types-input";

    }

    @PostMapping("update/{id}")
    public String update(Type type,@PathVariable Long id){
        typeService.update(id,type);
        return "redirect:/admin/types";
    }
