Django and weasyprint, merge pdf

Took me a while, but i solved it, was my fault for not understand the documentation lol, here is the code if anyone have the same problem:

def verpdf(request, pk):
    odet = get_object_or_404(Note, pk = pk)
    template = get_template('pdfnot.html')
    template1 = get_template('pdfnot2.html')
    p1 = template.render({'odet': odet}).encode(encoding="ISO-8859-1")
    p2 = template1.render({'note':odet}).encode(encoding="ISO-8859-1")
    pdf1 = HTML(string=p1)
    pdf2 = HTML(string=p2)
    pdf11 = pdf1.render()
    pdf12 = pdf2.render()

    val = []

    for doc in pdf11, pdf12:
        for p in doc.pages:
            val.append(p)

    pdf_file = pdf11.copy(val).write_pdf() # use metadata of pdf11

    http_response = HttpResponse(pdf_file, content_type='application/pdf')
    http_response['Content-Disposition'] = 'filename="report.pdf"'

    return http_response

And with this an pdf output with two pages.
