안녕하세요. 장고를 활용하여 웹사이트를 만들고 있는 중입니다. 제가 지금 구현 중인 부분은 식단표 페이지로, 모델 단과 데이터 입력 단에서 막혀서 질문을 드립니다. 우선, "menu_list.html" 화면을 아래와 같이 띄우려고 합니다. 이를 위해 모델 구현부터 질문드리겠습니다. 첫번째 질문은 모델 구현에 대한 부분입니다. 최초 모델보다 수정 모델이 더 바람직한 방향인지 궁금합니다. #최초 model class Menu(models.Model): author = models.ForeignKey(User, on_delete=models.CASCADE, related_name='author_menu') date = models.DateField(unique=True) breakfast = models.TextField() lunch = models.TextField() dinner = models.TextField() voter = models.ManyToManyField(User, related_name='voter_menu') def __str__(self): return self.breakfast #수정 model TYPE_CHOICES = ( ("아침", "아침"), ("브런치", "브런치"), ("점심", "점심"), ("저녁", "저녁"), ) class Dish(models.Model): dish = models.CharField(max_length=10) voter = models.ManyToManyField(User) def __str__(self): return self.dish class Menu(models.Model): type = models.CharField(choices=TYPE_CHOICES, max_length=3) date = models.DateField() dish = models.ManyToManyField(Dish) 최초 모델은 아무런 고민 없이 TextField로 식사 정보를 모두 받아왔으나 성능 측면에서 비효율적일 수 있다는 생각이 들어 고민을 하고 수정하였습니다. 수정된 설계가 더 바람직한 것인지 의문이 들어 질문드립니다. 더 바람직한 방향이 있다면 가르쳐주세요!! 두번째 질문은, 수정된 model을 통해 값을 받아오는 것이 어려워서 질문드립니다. #forms.py TYPE_CHOICES = ( ("아침", "아침"), ("브런치", "브런치"), ("점심", "점심"), ("저녁", "저녁"), ) class DishMenuForm(forms.Form): date = forms.DateField(widget=forms.DateInput(attrs={'type': 'date'}, format="%Y-%M-%d"),label='date') type = forms.ChoiceField(choices=TYPE_CHOICES, label='type') dish = forms.CharField(label='dish', max_length=10) def save(self, commit=True): menu = Menu(**self.cleaned_data) if commit: menu.save() return menu #menu_form.html {% extends 'layout.html' %} {% load static %} {% block content %} <script src ="{% static 'js/menu.js' %}"></script> <div class="container"> <h5 class="my-3 border-bottom pb-2">메뉴 입력하기</h5> <form method="post"> {% csrf_token %} <div id ="dishMenuForm"> <div class="mb-3"> <label for="date" class="form-label">날짜</label> <input type="date" class="form-control" name="date" id="date" width='50px'> </div> <div class="mb-3"> <label for="breakfast" class="form-label">아침</label> <select name='type' id ='type' class='form-control'> <option value="">시간대를 정해주세요.</option> <option value='아침'>아침</option> <option value='점심'>점심</option> <option value='저녁'>저녁</option> <option value='브런치'>브런치</option> </select> </div> <div class="mb-3"> <label for="dish" class="form-label">요리</label> <textarea class="form-control" name="dish[]" id="dish" rows="1"></textarea> </div> <div class="mb-3"> <label for="dish" class="form-label">요리</label> <textarea class="form-control" name="dish[]" id="dish" rows="1"></textarea> </div> <div class="mb-3"> <label for="dish" class="form-label">요리</label> <textarea class="form-control" name="dish[]" id="dish" rows="1"></textarea> </div> </div> <input type='submit' value='입력' /> </form> </div> {% endblock %} 사진처럼 form.html 화면에서 dish의 form들을 동적으로 추가하여 저장하고 싶습니다. 템플릿 파일에서 dish의 name을 배열로 받아와 view 단에서 반복문을 사용하여 데이터를 저장할 수 있는지 궁금합니다. 성능을 위해 매번 데이터를 저장할때마다 dish 테이블에 이미 값이 있는지를 확인하고 저장해야하는 것인지, 데이터를 저장할때마다 분기를 돈다면 성능에 더 악영향을 미칠 것 같은데 어떤 방향으로 개발해야 하는지 궁금합니다. 이런 식의 방향이 맞는지 아니면 더 잘 쓰이는 방법이 있는지 알려주세요.. 질문이 길고 장황하지만 답변 부탁드립니다.

안녕하세요, 처음보는 문법이 궁금해 질문드립니다. "그래프 기초" 강의에서 12:19 부분에 for (int vertex : adjacent[0]) 라는 문구가 있는데 여기서 for문이 어떻게 동작하는지 모르겠습니다. :이 뭔지도 잘 모르겠습니다.. 설명해주시면 감사하겠습니다.!
앞선 강의를 들으니 max를 이용해서 문제가 풀렸는데, 2중 for문을 이용한 경우 결과가 안나와요... 조건은 만족하는데 i일때 j보다 큰 모든 경우에 푸쉬 되거나 카운팅이 되는데, 한번만 호출 되게 하는 방법이 궁금합니다. function solution(arr) { let answer = []; answer.push(arr[0]); for (let i = 1; i < arr.length; i++) { for (let j = 0; j < i; j++) { if (arr[i] > arr[j]) { answer.push(arr[i]); } } } return answer; } let arr = [130, 135, 148, 140, 145, 150, 150, 153]; console.log(solution(arr));

안녕하세요. 정성을 다해 만들어주신 강의 잘 듣고 있습니다. kafka 관련 CRUD 문의 드립니다. DB CRUD관련 이벤트를 모두 수집하여 처리하고자 합니다. kafka 및 kafka debezium 플러그인을 활용하여 아래와 같은 DB CRUD 관련 Topic 정보를 수집 하였습니다. ["payload": { "before": { "id": 22, "name": "chp" }, ...중략 ] 이러한 CRUD Topic정보를 DB 에 적용하려면 sinkconnector 를 활용하는 방법외에 어떠한 다른 방법이 있을까요? 해당 json Topic을 java 에서 파싱하여 응용프로그램 레벨에서 DB를 처리해야 하는건지 다른 처리 패턴이나 솔루션 혹은 플러그인이 있을까요? 해외사이트 구글링을 해봐도 debezium을 통해 CRUD Topic 정보를 수집하는 것 까지만 나오고 이후 처리에 대해서는 어떠한 내용도 없어서 문의드리게 되었습니다.
강의와 같은 뷰 템플릿에서 보내는 post요청입니다. 기존 Post /study/path 의 경우 @PostMapping("/study/path") public String updateStudyPath(@CurrentUser Account account, @PathVariable String path, @RequestParam String newPath, Model model, RedirectAttributes attributes) { Study study = studyService.getStudyToUpdateStatus(account, path); if (!studyService.isValidPath(newPath)) { model.addAttribute(account); model.addAttribute(study); model.addAttribute("studyPathError", "해당 스터디 경로는 사용할 수 없습니다. 다른 값을 입력하세요."); return "study/settings/study"; } studyService.updateStudyPath(study, newPath); attributes.addFlashAttribute("message", "스터디 경로를 수정했습니다"); return "redirect:/study/" + getPath(newPath) + "/settings/study"; } 같은 이름의 경로 요청시, 변경이 불가한 메세지를 나타내고, 페이지는 /study//settings/study를 나타내지만 주소창은 post요청의 영향으로 추가적으로 path가 더 붙는 것을 확인했습니다. 이상태에서 의도적일순 있으나 URL자체로 요청을 보내는 경우 /path가 붙은 Get요청을 하게되면 아래와 같은 화면을 보게 됩니다. 따라서 해당 문제점을 해결하기 위해 아래 처럼 변경하였습니다. @PostMapping("/study/path") public String updateStudyPath(@CurrentUser Account account, @PathVariable String path, @RequestParam String newPath, Model model, RedirectAttributes attributes) { Study study = studyService.getStudyToUpdateStatus(account, path); if (!studyService.isValidPath(newPath)) { model.addAttribute(account); model.addAttribute(study); attributes.addFlashAttribute("studyPathError", "해당 스터디 경로는 사용할 수 없습니다. 다른 값을 입력하세요."); return "redirect:/study/" + getPath(newPath) + "/settings/study"; } studyService.updateStudyPath(study, newPath); attributes.addFlashAttribute("message", "스터디 경로를 수정했습니다"); return "redirect:/study/" + getPath(newPath) + "/settings/study"; } 기존의 model에 추가한 attribute는 리다이렉트 요청시 없어지기 때문에 메세지 출력에 필요한 studyPathError는 FlashAttirbute로 변경해주었습니다. 잘못된 경로변경 요청시 결과입니다. redirect 결과로 /path가 붙어 나오지 않음 이 경험으로 위와 같은 상황에서는 Post요청으로 Redirect가 더 안전(?)하다고 생각했습니다. 하지만 매번 Redirect시킬수는 없을 것 같은데 존재하지 않는 API의 경우에 기준 URL로 리다이렉트 시키나요? 예를 들자면 /study/path/settings/study/path 의 경우에 /study/path/settings처럼 예상되는 url들의 경우 getMapping으로 다중처리하는 걸까요?
