Django models to HTML. Then, HTML to PDF

I am trying to export django models data (admin side data) into a PDF file. For that first I created a HTML file to render the data from models. The HTML file I created

It worked successfully and showed the data from the models correctly. Successfully worked (I create a url for it to check whether it is working or not)

Then I tried to render the same html file to PDF. I ran the server and I generated a pdf file. PDF file I expected it will show the data also. But It only showed the table border.

You can see my folders and names in the 1st photo. I thing it is enough to add this code. If you need full code please tell me. This is my views.py from app.

def render_to_pdf(template_src, context_dict={}):
template = get_template(template_src)
html  = template.render(context_dict)
result = BytesIO()
pdf = pisa.pisaDocument(BytesIO(html.encode("ISO-8859-1")), result)
if not pdf.err:
    return HttpResponse(result.getvalue(), content_type='application/pdf')
return None


class ViewPDF(View):
    def get(self, request, *args, **kwargs):

        pdf = render_to_pdf('app/pdf_template.html')
        return HttpResponse(pdf, content_type='application/pdf')

Can't I use the same html file to get the data as pdf? Can anyone tell me what wrong I did?

pdf_template.html

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>This is my first pdf</title>
</head>
<body>
 <center>
    <h2>User Table</h2>
    <table border="1">
        <tr>
            <th>Username</th>
            <th>E-mail</th>
            <th>Country</th>
            <th>City</th>
        </tr>
        {% for result in user %}
        <tr>
            <td>
                {{result.username}}
            </td>
            <td>
                {{result.email}}
            </td>
            <td>
                {{result.country}}
            </td>
            <td>
                {{result.city}}
            </td>
        </tr>
        {% endfor %}
    </table>
</center>
</body>
</html>
Solution

  • I got the correct out put. I am posting this as an answer so that it will use for someone else too.

    class ViewPDF(View):
def get(self, request, *args, **kwargs):
    context={}
    context['user'] =user.objects.all()
    pdf = render_to_pdf('app/pdf_template.html',context_dict=context)
    return HttpResponse(pdf, content_type='application/pdf')

    In the views.py I modified the code like above.

    The PDF output
