3. 응용 프로그램 만들기
(1) 명령 작성

(venv)python manage.py startapp samplepdf

(2) 파일 구조

C:\data\python\mysite
│  db.sqlite3
│  manage.py
│  
├─mysite
│  │  settings.py
│  │  urls.py
│  │  wsgi.py
│  │  __init__.py
・・・・
│          
├─samplepdf
│  │  admin.py
│  │  apps.py
│  │  models.py
│  │  tests.py
│  │  urls.py
│  │  views.py
│  │  __init__.py
│  │  
・・・・

4. 프로젝트 전체 설정
(1)mysite\urls.py
urls.py

urlpatterns = [
    path('samplepdf/', include('samplepdf.urls')),  #追加
    path('admin/', admin.site.urls),
]

(2)mysite\settings.py
settings.py

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'samplepdf', # 追加
]

5. 어플리케이션 설정
(1)samplepdf\urls.py
startapp 명령에서 urls.py를 만들지 않았으니 서류를 만들어 주세요.
urls.py

from django.conf.urls import url
from . import views

app_name = 'samplepdf'
urlpatterns = [
    url('', views.index, name='index'),
]

(2)samplepdf\views.py
views.py

from django.http import HttpResponse
from reportlab.pdfgen import canvas

# Create the HttpResponse object with the appropriate PDF headers.
def index(request):
    response = HttpResponse(content_type='application/pdf')
    response['Content-Disposition'] = 'attachment; filename="somefilename.pdf"'
    # Create the PDF object, using the response object as its "file."
    p = canvas.Canvas(response)
    # Draw things on the PDF. Here's where the PDF generation happens.
    # See the ReportLab documentation for the full list of functionality.
    p.drawString(1, 800, "Hello world.")
    # Close the PDF object cleanly, and we're done.
    p.showPage()
    p.save()
    return response
