Render HTML to PDF in Django site

Question

Try the solution from Reportlab.

Download it and install it as usual with python setup.py install

You will also need to install the following modules: xhtml2pdf, html5lib, pypdf with easy_install.

Here is an usage example:

First define this function:

import cStringIO as StringIO
from xhtml2pdf import pisa
from django.template.loader import get_template
from django.template import Context
from django.http import HttpResponse
from cgi import escape


def render_to_pdf(template_src, context_dict):
    template = get_template(template_src)
    context = Context(context_dict)
    html  = template.render(context)
    result = StringIO.StringIO()

    pdf = pisa.pisaDocument(StringIO.StringIO(html.encode("ISO-8859-1")), result)
    if not pdf.err:
        return HttpResponse(result.getvalue(), content_type='application/pdf')
    return HttpResponse('We had some errors<pre>%s</pre>' % escape(html))

Then you can use it like this:

def myview(request):
    #Retrieve data or whatever you need
    return render_to_pdf(
            'mytemplate.html',
            {
                'pagesize':'A4',
                'mylist': results,
            }
        )

The template:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
    <head>
        <title>My Title</title>
        <style type="text/css">
            @page {
                size: {{ pagesize }};
                margin: 1cm;
                @frame footer {
                    -pdf-frame-content: footerContent;
                    bottom: 0cm;
                    margin-left: 9cm;
                    margin-right: 9cm;
                    height: 1cm;
                }
            }
        </style>
    </head>
    <body>
        <div>
            {% for item in mylist %}
                RENDER MY CONTENT
            {% endfor %}
        </div>
        <div id="footerContent">
            {%block page_foot%}
                Page <pdf:pagenumber>
            {%endblock%}
        </div>
    </body>
</html>

Hope it helps.

Try wkhtmltopdf with either one of the following wrappers

django-wkhtmltopdf or python-pdfkit

This worked great for me,supports javascript and css or anything for that matter which a webkit browser supports.

For more detailed tutorial please see this blog post

https://github.com/nigma/django-easy-pdf

Template:

{% extends "easy_pdf/base.html" %}

{% block content %}
    <div id="content">
        <h1>Hi there!</h1>
    </div>
{% endblock %}

View:

from easy_pdf.views import PDFTemplateView

class HelloPDFView(PDFTemplateView):
    template_name = "hello.html"

If you want to use django-easy-pdf on Python 3 check the solution suggested here.

I just whipped this up for CBV. Not used in production but generates a PDF for me. Probably needs work for the error reporting side of things but does the trick so far.

import StringIO
from cgi import escape
from xhtml2pdf import pisa
from django.http import HttpResponse
from django.template.response import TemplateResponse
from django.views.generic import TemplateView

class PDFTemplateResponse(TemplateResponse):

    def generate_pdf(self, retval):

        html = self.content

        result = StringIO.StringIO()
        rendering = pisa.pisaDocument(StringIO.StringIO(html.encode("ISO-8859-1")), result)

        if rendering.err:
            return HttpResponse('We had some errors<pre>%s</pre>' % escape(html))
        else:
            self.content = result.getvalue()

    def __init__(self, *args, **kwargs):
        super(PDFTemplateResponse, self).__init__(*args, mimetype='application/pdf', **kwargs)
        self.add_post_render_callback(self.generate_pdf)


class PDFTemplateView(TemplateView):
    response_class = PDFTemplateResponse

Used like:

class MyPdfView(PDFTemplateView):
    template_name = 'things/pdf.html'

After trying to get this to work for too many hours, I finally found this: https://github.com/vierno/django-xhtml2pdf

It's a fork of https://github.com/chrisglass/django-xhtml2pdf that provides a mixin for a generic class-based view. I used it like this:

    # views.py
    from django_xhtml2pdf.views import PdfMixin
    class GroupPDFGenerate(PdfMixin, DetailView):
        model = PeerGroupSignIn
        template_name = 'groups/pdf.html'

    # templates/groups/pdf.html
    <html>
    <style>
    @page { your xhtml2pdf pisa PDF parameters }
    </style>
    </head>
    <body>
        <div id="header_content"> (this is defined in the style section)
            <h1>{{ peergroupsignin.this_group_title }}</h1>
            ...

Use the model name you defined in your view in all lowercase when populating the template fields. Because its a GCBV, you can just call it as '.as_view' in your urls.py:

    # urls.py (using url namespaces defined in the main urls.py file)
    url(
        regex=r"^(?P<pk>\d+)/generate_pdf/$",
        view=views.GroupPDFGenerate.as_view(),
        name="generate_pdf",
       ),
