Courses Plus Student 110 PointsHow to validate if the view contains two forms
Hello, I have two forms in the view that add product and add category. When I give incorrect data in the form(validation), the category returns me error Error during execution of processor 'org.thymeleaf.spring4.processor.attr.SpringInputGeneralFieldAttrProcessor' (addProduct:20) Why spring also validates the product of forms.
Controler:
@PostMapping("categories")
public String add(@Valid Category category, BindingResult result, Model model,RedirectAttributes redirectAttrs) {
if (result.hasErrors()) {
return "addProduct";
} else {
categoryRepository.save(category);
try {
fileSave.save(category.getImage().getBytes(), category.getName() + ".png");
} catch (IOException e) {
e.printStackTrace();
}
return "redirect:product/add";
}
@PostMapping("/add")
public String add(
Model model,
@Valid Product product,
BindingResult result){
if (result.hasErrors()) {
return "addProduct";
} else {
ProductDto productDto = mapper.mapToProductDto(product);
productService.add(productDto);
return "redirect:productList";
}
