indexページの作成

とりあえず簡単にindexページが表示されるだけのdjangoアプリをデプロイする。

プロジェクトを”Django_app”
アプリを”hello”で作成

Django_app/urls.py

from django.contrib import admin
from django.urls import path,include
import hello.views as hello


urlpatterns = [
    path("", hello.index, name="index"),
    path('admin/', admin.site.urls),
    path('hello/', include('hello.urls')),
]

from django.contrib import admin

from django.urls import path,include

import hello.views as hello

urlpatterns = [

path("", hello.index, name="index"),

path('admin/', admin.site.urls),

path('hello/', include('hello.urls')),

]

hello/views.py

from django.shortcuts import render
from django.http import HttpResponse


def index(request):
    return HttpResponse("indexページ")

def top(request):
    return HttpResponse("Helloトップ")

from django.shortcuts import render

from django.http import HttpResponse

def index(request):

return HttpResponse("indexページ")

def top(request):

return HttpResponse("Helloトップ")

hello/urls.py

from django.urls import path
from . import views

urlpatterns = [
    path('', views.top, name='top'),
]

from django.urls import path

from . import views

urlpatterns = [

path('', views.top, name='top'),

]

Django_app/setting.py

一旦データベースの設定は全てコメントアウトする。
ロガーの出力先のフォルダはmkdirで作る

静的ファイルとメディアファイルはアプリケーションサーバーの負担を
減らす為にwebサーバーから返す事もできる。

現時点ではアプリケーションサーバーから静的ファイルを返しているが
webサーバーから返す場合は/usr/share/nginx/html/staticと
/usr/share/nginx/html/mediaフォルダを作成してsudo vi /etc/nginx/nginx.confで
コメントアウトしているlocation /staticとlocation /mediaを有効化する。

indexページの作成

プロジェクトを”Django_app”
アプリを”hello”で作成

Django_app/urls.py

urls.pyはプロジェクトフォルダーにあるがビュー処理はhelloアプリ内で実行

from django.contrib import admin
from django.urls import path,include
<span style="color: #0000ff;">import hello.views as hello</span>

urlpatterns = [
    path("", <span style="color: #0000ff;">hello</span>.<span style="color: #ff0000;">index</span>, name="index"),
]

from django.contrib import admin

from django.urls import path,include

import hello.views as hello

urlpatterns = [

path("", hello.index, name="index"),

]

hello/views.py

from django.shortcuts import render
from django.http import HttpResponse

def <span style="color: #ff0000;">index</span>(request):
    return HttpResponse("indexページ")

from django.shortcuts import render

from django.http import HttpResponse

def index(request):

return HttpResponse("indexページ")

index以外のページの作成

urlの末尾に”admin”と”hello”がつく場合でhelloはinclude関数を使い、
helloアプリ内でurlとビューの処理を行う

Django_app/urls.py

from django.contrib import admin
from django.urls import path,include
<span style="color: #ff0000;">import hello.views as hello</span>


urlpatterns = [
    path("", hello.index, name="index"),
    path('admin/', admin.site.urls),
    path('hello/', <span style="color: #ff0000;">include('hello.urls')</span>),
]

from django.contrib import admin

from django.urls import path,include

import hello.views as hello

urlpatterns = [

path("", hello.index, name="index"),

path('admin/', admin.site.urls),

path('hello/', include('hello.urls')),

]

hello/urls.py

from django.urls import path
from . import views

urlpatterns = [
    path('', views.<span style="color: #0000ff;">top</span>, name='top'),
]

from django.urls import path

from . import views

urlpatterns = [

path('', views.top, name='top'),

]

hello/views.py

from django.shortcuts import render
from django.http import HttpResponse

def index(request):

# Create your views here.

def <span style="color: #0000ff;">top</span>(request):
    return HttpResponse("Helloトップ")

from django.shortcuts import render
