Roo hidden field in Jspx

Question

I want to have a hidden field in a jspx file.

What I would like to do is automatically save the name of the authentificated user in the database. Here is how I do it :

Modify my bean with :

 public void Got.setUserkt(String userkt) {
        final String currentUser = SecurityContextHolder.getContext().getAuthentication().getName();
        this.userkt = currentUser;
    }

Looking around I found out that i had to use render="false" in my create.jspx page but when render is set to false, no data from my input field is saved in my database.

What am I doing wrong ?

Answer 1

I will resume what I did, for my fellow rookies.

First step : Cut my method from my roo controler (EntityController_Roo_Controller.aj)

  @RequestMapping(method = RequestMethod.POST)

    public String create(@Valid Got got, BindingResult bindingResult, Model uiModel, HttpServletRequest httpServletRequest) {

        if (bindingResult.hasErrors()) {

            uiModel.addAttribute("got", got);

            addDateTimeFormatPatterns(uiModel);

            return "gots/create";

        }

        uiModel.asMap().clear();

        got.persist();

        return "redirect:/gots/" + encodeUrlPathSegment(got.getId().toString(), httpServletRequest);

    }

Second Step : Paste the methode into the java contoller (EntityController.java)

Third Step : Edit the method to get the usernmae and to modifiy my method with it

1. added Principal principal as a parameter

2. update my entity : got.setUserkt(principal.getName());

   @RequestMapping(method = RequestMethod.POST)

   public String create(@Valid Got got, BindingResult bindingResult, Model uiModel, HttpServletRequest httpServletRequest, Principal principal) {
   
       if (bindingResult.hasErrors()) {
   
           uiModel.addAttribute("got", got);
   
           addDateTimeFormatPatterns(uiModel);
   
           return "gots/create";
   
       }
   
       uiModel.asMap().clear();
   
       got.setUserkt(principal.getName()); 
   
       got.persist();
   
   
   
       return "redirect:/gots/" + encodeUrlPathSegment(got.getId().toString(), httpServletRequest);
   
   }
   

Thanks again !
