Convert html to pdf using Python/Flask


I want to generate pdf file from html using Python + Flask. To do this, I use xhtml2pdf. Here is my code:

def main():
    pdf = StringIO()
    pdf = create_pdf(render_template('cvTemplate.html', user=user))
    pdf_out = pdf.getvalue()
    response = make_response(pdf_out)
    return response

def create_pdf(pdf_data):
    pdf = StringIO()
    pisa.CreatePDF(StringIO(pdf_data.encode('utf-8')), pdf)
    return pdf

In this code file is generating on the fly. BUT! xhtml2pdf doesn't support many styles in CSS, because of this big problem to mark page correctly. I found another instrument(wkhtmltopdf). But when I wrote something like:

pdf = StringIO()
data = render_template('cvTemplate1.html', user=user)
WKhtmlToPdf(data.encode('utf-8'), pdf)
return pdf

Was raised error:

AttributeError: 'cStringIO.StringO' object has no attribute 'rfind'

And my question is how to convert html to pdf using wkhtmltopdf (with generating file on the fly) in Flask?

Thanks in advance for your answers.


Solution

  • The page need render, You can use pdfkit:

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

    https://github.com/JazzCore/python-pdfkit

    Example in document.

    import pdfkit
    
    pdfkit.from_url('http://google.com', 'out.pdf')
    pdfkit.from_file('test.html', 'out.pdf')
    pdfkit.from_string('Hello!', 'out.pdf')  # Is your requirement?
