how to encode dynamic django variable from a html template in python coding
Question
I would like to encode '{{ variable }}' and '{% for loop ...%}' from a template to a variable called 'html'. So that I can render it as PDF file using pisa.CreatePDF. I am using xhtml2pdf to generate PDF.
html="<html><body>{% for inventory in filter.qs %} {{ inventory.pk }} {{ inventory.name }} {{ inventory.price }} {{ inventory.quantity }} {% endfor %} </body></html>".
the code above is not working.
it doesn't give any values from database. Simply the text below: {% for inventory in filter.qs %} {{ inventory.pk }} {{ inventory.name }} {% endfor %} in the PDF output.

Something like this:
from django.template import Template, Context
html = """
<html>
<body>
{% for inventory in inventories %}
{{ inventory.pk }} {{ inventory.name }} {{ inventory.price }} {{ inventory.quantity }}
{% endfor %}
</body>
</html>
"""
t = Template(html)
inventories = Inventory.objects.all()
c = Context({'filter': filter})
raw_html = t.render(c)
print(raw_html)
