この記事は 約 1分12秒 で読めます。
前回からの続きやっていきます。
前回までの準備でAPIが整いましたので、テンプレートにvue.jsを組み込んでいきたいと思います。
このログは、こちらのレポジトリでDjango+Dockerセットアップ後の環境を想定しています。
URL設定
プロジェクトのurls.pyにarticleまでの経路を設定します。
|
1 2 3 |
urlpatterns = [ url(r'', include('article.urls')), # 追加 ] |
そのあとは、アプリケーション側でもurlを設定します。
|
1 2 3 4 5 6 7 |
from django.conf.urls import url from .views import IndexTemplateView app_name = 'article' urlpatterns = [ url(r'^article/$', IndexTemplateView.as_view(), name="index"), ] |
ビュー作成
経路を設定できたので、ビューを作っていきましょう。
|
1 2 3 4 |
from django.views.generic import TemplateView class IndexTemplateView(TemplateView): template_name = 'article/index.html' |
テンプレート作成
ビューができたので、表示用のテンプレートを作っていきましょう。

ページを開いて動きの確認
http://localhost:8000/article/を開くと
以下のような画面になっていると思います。
記事の追加と編集と削除が行えるCRUDの基本が完成しましたね！
HTMLのソースを見れば何をしているのかだいたい理解できると思います。
vue.jsもわかりやすいですね。
以上です。
