<a href="{% url 'update' b.id %}"><button>MOD</button></a>
<a href="{% url 'delete' b.id %}"><button>DEL</button></a>

 

② urls.py에 path 추가.

(books/urls.py)

from django.urls import path
from . import views

urlpatterns = [
    path('index/', views.index, name="index"),
    path('detail/<bpk>', views.detail, name="detail"),
    path('delete/<bpk>', views.delete, name="delete"),
    path('create/', views.create, name="create"),
    path('update/<bpk>', views.update, name="update")
]

 

③ views.py에 함수 추가.

(books/views.py)

...
def update(request, bpk):
    b = Books.objects.get(id=bpk)
    context = {
        "b" : b
    }
    return render(request, "books/update.html", context)

 

④ templates/books 폴더에 update.html 생성.

(update.html)

<h1>UPDATE PAGE</h1>

<b>제목</b><input type="text" value="{{ b.name }}"disabled><br><br>
<form method="post" name="updateForm">
    {% csrf_token %}
    <b>지은이</b><input name="bwriter" type="text" value="{{ b.writer }}"><br><br>
    <b>조회수</b><input name="bhit" type="text" value="{{ b.hit }}"><br><br>
    <b>내용</b><br><textarea name="bcontent" cols="80" rows="8">{{ b.content }}</textarea><br><br>
    
    <button type="button" onclick="check()">DONE</button>
    <a href="{% url 'index' %}"><button type="button">HOME</button></a>
</form>

<script>
    function check() {
        cf = document.updateForm;
        if(!cf.bwriter.value) {
            alert("지은이를 입력하세요!")
        }
        else if(!cf.bcontent.value) {
            alert("내용을 입력하세요!")
        }
        else {
            cf.submit()
        }
    }
</script>

 

⑤ views.py에서 update구현 추가.

(books/views.py)

...
def update(request, bpk):
    b = Books.objects.get(id=bpk)
    
    if request.method == "POST":
        bw = request.POST.get("bwriter")
        bh = request.POST.get("bhit")
        bc = request.POST.get("bcontent")
        b.writer, b.hit, b.content = bw, bh, bc
        b.save()
        return redirect("detail", bpk)
    context = {
        "b" : b
    }
    return render(request, "books/update.html", context)
