[Django] Django 모델, 뷰, 템플릿, 폼을 사용하는 단계별 샘플

• 1단계: Django 프로젝트와 앱 생성

django-admin startproject myproject
cd myproject
python manage.py startapp myapp

• [ myproject/settings.py ]에서 생성한 앱을 등록:

INSTALLED_APPS = [
    ....
    'myapp',
]

---

• 2단계: [ myapp/models.py ] 에서 모델 정의:

from django.db import models

class Book(models.Model):
    title = models.CharField(max_length=200)
    author = models.CharField(max_length=200)
    publication_date = models.DateField()
    price = models.DecimalField(max_digits=6, decimal_places=2)

---

• 3단계 : [ myapp/forms.py ] 파일 생성 후, 폼 생성:

from django import forms
from .models import Book

class BookForm(forms.ModelForm):
    class Meta:
        model = Book
        fields = ['title', 'author', 'publication_date', 'price']

---

 

• 4단계 : [ myapp/views.py ] 에서 뷰 정의:

from django.shortcuts import render, redirect
from .forms import BookForm
from myapp.models import Book

def create_book(request):
    if request.method == 'POST':
        form = BookForm(request.POST)
        if form.is_valid():
            form.save()
            return redirect('book_list')
    else:
        form = BookForm()
    return render(request, 'myapp/template/create_book.html', {'form': form})

def book_list(request):
    books = Book.objects.all()
    return render(request, 'myapp/template/book_list.html', {'books': books})

---

• 5단계 : 탬플릿 생성

- myapp/templates/myapp/create_book.html 생성:

<h2>책 생성하기</h2>
<form method="post">
  {% csrf_token %}
  {{ form.as_p }}
  <button type="submit">저장</button>
</form>

- myapp/templates/myapp/book_list.html 생성:

<h2>책 목록</h2>
<ul>
  {% for book in books %}
    <li>{{ book.title }} - {{ book.author }}</li>
  {% endfor %}
</ul>

---

• 6단계 : [ root_project/ urls.py ] url 업데이트:

# root_project/urls.py

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('myapp/', include('myapp.urls')),
]

---

• 7단계 : [ myapp/urls.py ] 파일 생성 후, 앱 url 정의

from django.urls import path
from .views import create_book, book_list

urlpatterns = [
    path('create/', create_book, name='create_book'),
    path('list/', book_list, name='book_list'),
]
