python - 打印为 PDF Django 和 ReportLab

Question

我目前在 Django 中有这个 View ，它可以完美地在我的 html 页面上呈现一堆记录

def patient_page(request, id):
    pat = models.patient.objects.get(pk=id) # Goes to patient models returns pk according to page
    rec = models.record.objects.all().filter(patient_assign__pk=id).order_by('-date')
    return render(request=request,
                  template_name = 'main/patient_page.html',
                  context = {"pats":pat,
                             "rec":rec
                             }
                  )

我也有这个打印完美的代码，我可以轻松插入一个变量。

def write_pdf_view(textobject):

    #Need to play with filename.
    response = HttpResponse(content_type='application/pdf')
    response['Content-Disposition'] = 'inline; filename="txt_obj.pdf"'
    buffer = BytesIO()
    my_canvas = canvas.Canvas(buffer)

    # Create textobject(s)
    textobject = my_canvas.beginText(30 * mm, 65 * mm)
    textobject.setFont('Times-Roman', 8)
    textobject.textLine(text="+ Hello This text is written 30mm in and 65mm up from the mark")

    my_canvas.drawText(textobject)

    title = "this is my title"
    my_canvas.setTitle(title)


    my_canvas.showPage()
    my_canvas.save()
    pdf = buffer.getvalue()
    buffer.close()
    response.write(pdf)
    return response

我的问题，有谁知道我如何渲染为 pdf 并打印为 PDF，即在 html 上的记录旁边，我有一个打印按钮，当前运行我的打印为 pdf 脚本。

好吧，当然我是一个新手，正在学习，但是我所做的就是通过 url 将记录号传递到我的函数中。我确信有更好(更安全)的方法，但我现在用 super 用户装饰器来保护它。 (从这里:django @login_required decorator for a superuser)

{% for rec in rec %}
<ul>
  <b>Created: </b>{{ rec.date  }}  <b>Record:</b>  &nbsp <a href="{% url 'main:record_specific' rec.exam_record_number %}">{{ rec.exam_record_number }}</a>
<a href="{% url 'main:print_record' rec.exam_record_number %}" download style="float: right;">Print</a>
 <br>
    <p>{{ rec.exam_record  |safe}}</p>
  <hr>
</ul>
