Djangoの {{ 〇〇 |safe }}とは

Posted at

|safeはHTMLタグを描き出せるようにするためのフィルター機能。

通常、{{ 〇〇 }}の中にHTMLタグを埋め込んでもただのテキストとして表示されてしまう。
そこで、タグとして表示させたい時には{{ 〇〇 |safe }}とする。

例として、<h1>hello</h1>を表示させてみる

index.html
<body class="container">
    {{title}}
    {{title|safe}}
</body>
views.py
def index(request):
    params = {
        'title':'<h1>hello</h1>'
    }
    return render(request, 'hello/index.html', params)

次のようになる。
