Flaskテンプレートが相対パスで指定されていません

Question

Flaskアプリケーションのテンプレートフォルダにindex.htmlテンプレートをレンダリングしようとしています。しかし、私はTemplateNotFoundエラーが発生します。テンプレートが存在します。どのようにレンダリングするのですか？

@app.route('/') 
def index(): 
    return render_template('../../templates/index.html')

Answer 1

render_templatetemplatesフォルダはそれにその検索パスを持っている神社のENVで見上げたことが名前を取ります。パスはの後に指定してください。

# index.html is in the templates folder 
render_template('index.html') 

# users/detail.html is in a sub-folder under templates 
render_template('users/detail.html')
