python）を使用してレポートラボを使用してHTMLドキュメントをPDFに変換する方法

レポートラボを使用して、作成したhtmlドキュメントをpdfに変換しようとしています。 htmlドキュメントは以下のとおりです。私はこれを行う方法がわからず、オンラインで調べましたが、これに対する解決策を見つけることができないようです。

Djangoフレームワークを使用すると、Django-easy-pdfを使用できます。HtmlからPDFを生成するのが最も簡単な方法だと思います。テンプレートとビューは次のとおりです。私のプロジェクトの：

#Import the easy_pdf rendering
from easy_pdf.rendering import render_to_pdf_response

#Here's the detail view function
def detail_to_pdf(request,id):
    template = 'renderdetail.html'
    kucing = Kucing.objects.get(id = id)
    context = {'kucing' : kucing}
    return render_to_pdf_response(request,template,context)

テンプレートは次のとおりです。

{% extends "base.html" %}

{% block extra_style %}
    <style type="text/css">
        body {
            font-family: "Helvetica", "sans-serif";
            color: #333333;
        }
    </style>
{% endblock %}

{% block content %}
    <div id="content">
        <div class="main">
            <h1>PROFILE : {{ kucing.nama }}- ID:{{ kucing.id }}</h1>
            <img src="/media/{{ kucing.foto }}"><br>
            <p>Nama : {{ kucing.nama }}</p><br>
            <p>Hp : {{ kucing.hp}}</p><br>
            <p>Poin : {{ kucing.poin }}</p><br>
            <a href="{% url 'kucing_makan' kucing.id %}">Makan</a>
            <a href="{% url 'kucing_berburu' kucing.id %}">Berburu</a>
            <hr>
            <h5><a href="{% url 'kucing_home' %}">Back To Home</a></h5>|
            <h5><a href="{% url 'kucing_list' %}">See Another Kucing</a></h5>
        </div>
    </div>
{% endblock %}

PDFTemplateViewsをオーバーライドすることにより、クラスベースのビューを使用することもできます。詳細については、 Docs をご覧ください。

または、pdfkitを使用できます：

https://pypi.python.org/pypi/pdfkit

それを使用する前に、いくつかのものをインストールする必要があります：

pip install pdfkit
Sudo apt-get install wkhtmltopdf

PDFを生成するためのサンプルコード：

import pdfkit

pdfkit.from_url('http://stackoverflow.com', 'out.pdf')
pdfkit.from_file('test.html', 'out2.pdf')
pdfkit.from_string('Thanks for reading!', 'out3.pdf')
