I'm trying to create a PDF with checkboxes that can be checked (using python). I've been trying to use pisa to generate the pdf and have looked around the internet and tried different examples but I cannot find out how to make an editable PDF.

This is my most recent attempt:

import cStringIO
import ho.pisa as pisa
import os

# shortcut for dumping all logs on screen
pisa.showLogging()

def HTML2PDF(data, filename, open=False):
    """
        Simple test showing how to create a PDF file from
        PML Source String. Also shows errors and tries to start
        the resulting PDF
    """
    pdf = pisa.CreatePDF(cStringIO.StringIO(data), file(filename, "wb"))

    if open and not(pdf.err):
        os.startfile(str(filename))

    return not pdf.err

if __name__=="__main__":
    HTMLTEST = """
        <html>
            <body>
                <form name="deleteForm" method="get" action="">
                     User 1 <input type="checkbox" name="user" value="delete" />
                </form>
            </body>
        </html>
   """

   HTML2PDF(HTMLTEST, "test.pdf", open=True)

The form gives me an error:

Traceback (most recent call last):
  File "C:/Users/horeth/PycharmProjects/Reportlab/HTMLtoPF/Main.py", line 32, in 
      HTML2PDF(HTMLTEST, "test.pdf", open=True)
  File "C:/Users/horeth/PycharmProjects/Reportlab/HTMLtoPF/Main.py", line 14, in HTML2PDF
      pdf = pisa.CreatePDF(cStringIO.StringIO(data), file(filename, "wb"))
IOError: [Errno 13] Permission denied: 'test.pdf'

The check boxes are for readers to decide if a user needs to be deleted or not.

I'm wondering if there is a way to create an editable PDF document with Python. This is just one of the attempts I've made so far, as an example.

可能的原因。您没有对该目录的写入权限。该文件已存在，但您没有对其的写入权限。

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

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

调用这个函数

def myview(request):
    return render_to_pdf('HTMLTEST.html', { 'pagesize':'A4',})

创建一个单独的html文件

HTMLTEST.html

    <html>
        <body>
            <form name="deleteForm" method="get" action="">
                 User 1 <input type="checkbox" name="user" value="delete" />
            </form>
        </body>
    </html>
