Question

我带着一个我无法回答的新问题回来，整整一天都摸不着头脑。

我想通过点击＆＃34;下载PDF＆＃34;从网页生成PDF。按钮。我尝试了几个模块，包括Reportlab和XHTML2PDF，但我无法生成任何pdf，也无法下载...这是我在Reportlab上做的，Render HTML to PDF in Django site

- - views.py - -

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

def index_data(request):
#Code to generate data
     return render(request, "analytics/stat.html", locals())
     return render_to_pdf(
        'analytics/stat.html',
        {
            'pagesize':'A4',
            'mylist': results,
        }
    )

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))

- - urls.py - -

from django.conf.urls import include, url
from django.contrib import admin

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url(r'^$', "analytics.views.main_page", name="main_page"),
    url(r'^portail/$', "analytics.views.index_data", name="index"),
    url(r'^generate_pdf/$', "analytics.views.GroupPDFGenerate.as_view()", name="generate_pdf")

- - 模板分析/ stat.html - -

{% extends "analytics/layout.html" %}

{% block title %}
    Audience
{% endblock title %}

{% block head %}
 # Script to generate google charts
{% endblock head %}

{% block body %}
<div class="page-header">
  <h1 align="center"> Audience </h1>
</div>
<div class="row">
  <div class="col-md-1">
      <h3 align="center"><a href="/logout/">Logout</a></h3>
      <h3 align="center"><a href="statistiques.pdf">Download pdf</a></h3>
  </div>
 </div>

{% endblock %}

此外，还有更好的模块可供处理吗？

Answer 1

我建议使用wkhtmltopdf。

简短的回答？在Ubuntu上，安装二进制文件：

apt-get install wkhtmltopdf

在CentOS / RedHat上：

yum install wkhtmltox-0.12.2.1_linux-centos6-amd64.rpm

然后pip安装一个Python包：

pip install pdfkit

然后是代码：

import pdfkit

input_filename = 'README.html'
output_filename = 'README.pdf'

with open(input_filename, 'r') as f:
    html_text = f.read()

pdfkit.from_string(html_text, output_filename)

对于长篇答案和细节，我整理了一篇博文：

这应该照顾PDF创作;你必须决定如何处理下载。祝你好运！

Answer 2

如果您说您在生成PDF时遇到问题，我建议您先查看我在this answer中使用Reportlab，xhtml2pdf和django-easy-pdf中提到的示例。首先在浏览器中渲染PDF，然后继续获取下载链接。

Answer 3

from easy_pdf.rendering import render_to_pdf

def pdf(request):
    with open('example.pdf', 'wb') as f2:
        f2.write(render_to_pdf('you template', {'user': request.user}, encoding=u'utf-8'))

使用Django和Reportlab
