django-pdf-generator

Convert HTML to pdf with django using phantomjs

Requirements

• Python (2.7) (Need to be tested for 3.x)
• Django (1.10, 1.9) (Need to be tested for previous versions)
• PhantomJS

Installation

Install using pip :

pip install django_pdf_generator

Add pdf_generator to your INSTALLED_APPS setting.

    INSTALLED_APPS = (
        ...
        'pdf_generator',
    )

Add the pdf_generator urls below to your main urls.py

    urlpatterns = [
    ...
    url(r'^pdf-generator/', include('pdf_generator.urls', namespace='pdf_generator')),
    ...

Put phantomjs binary on your path or set the path manually in your settings using PHANTOMJS_BIN_PATH settings (see below).

Example

Generate a PDF with PDFGenerator class

Generate a pdf from an url

	from pdf_generator.generators import PDFGenerator

	pdf = PDFGenerator(url="https://github.com/charlesthk/django-pdf-generator",

Save it to the database using PdfDoc models :

    pdf.save(
            filename='pdf_generator',
            title="pdf_generator on github",
            description="Convert HTML to pdf with django using phantomjs")

Get the PDF as a Django ContentFile named 'my_pdf_file.pdf' :

    pdf_content_file = pdf.get_content_file('my_pdf_file') 

    # Return a Django HttpResponse with the PDF Attached named 'my_pdf_file.pdf':
    return pdf.get_http_response('my_pdf_file')

Return a Django HttpResponse with the PDF Attached named 'my_pdf_file.pdf':

    return pdf.get_http_response('my_pdf_file')

Generate a pdf just like Django render function :

urls.py

    url(r'^invoice$', views.invoice, name='invoice'),

views.py

    from pdf_generator.renderers import render_pdf

    def invoice(request):
        """
        Render an invoice
        The invoice.pdf file is returned
        """
        return render_pdf('invoice', request, 'front/invoice.html')

Juste add ?html=1 to the url to view the HTML instead of getting the pdf file.

PDFGenerator options

The PDFGenerator class accepts the following arguments :

• url [required]
• paperformat [Required] default to 'A4', examples: "5in7.5in", "10cm20cm", "A4", "Letter"

class PdfDoc(models.Model):
	"""

	"""
	title = models.CharField(verbose_name=_("Title"), max_length=255, blank=True)
	description = models.TextField(verbose_name=_("Description"), blank=True)
	document = models.FileField(verbose_name=_("Document PDF"), upload_to=pdf_settings.UPLOAD_TO)
	created_at = models.DateTimeField(auto_now=False, auto_now_add=True, verbose_name=_('Creation'))
	updated_at = models.DateTimeField(auto_now=True, auto_now_add=False, verbose_name=_('Update'))
