Build HTML from Django View

Question

I need to construct the HTML body from a Django view and I cannot find a solution to refer correctly a JPG file ( must say that the HTML is much larger then this, but with other stuff seems that is working for me ):

I've tried this:

from django.template import Template
...
html = Template('<IMG SRC="{% static "base/images/course/website-46-2.jpg" %}">')
return HttpResponse( html )

And I get this error:

Invalid block tag on line 1: 'static'. Did you forget to register or load this tag?

In Django template I resolve this by loading the static files:

{% load static %}

How can I do this in Python ( Django View ) ? Or any other suggestion is much appreciated.

I've tried different solution that I have found on this site and others but none seems to work for me.

Django Version: 2.2.1

You can create an engine with the static library as a built-in. This makes it available to the template without calling {% load static %} first.

from django.template import Template, Context, Engine

engine = Engine(builtins=['django.templatetags.static'])
template = engine.from_string('<IMG SRC="{% static "base/images/course/website-46-2.jpg" %}">')
return HttpResponse(template.render(Context()))

With this, I get this error: AttributeError at /course/1/ 'SafeText' object has no attribute 'get' – cristian Aug 20 '19 at 16:58
That's probably something like this (invalid view): https://stackoverflow.com/questions/43987462/django-safetext-object-has-no-attribute-get/43991530 – Nikolas Stevenson-Molnar Aug 20 '19 at 18:02
Not likely because I have a view like this: course( request, question_id ) and it's working without the suggested code. – cristian Aug 20 '19 at 18:08
Which version of Django are you using and which line is causing the exception? This works for me on Django 1.11. – Nikolas Stevenson-Molnar Aug 20 '19 at 18:36
Django 2.2.1, line: \lib\site-packages\django\middleware\clickjacking.py in process_response, line 26 – cristian Aug 21 '19 at 03:51
Can you send settings.py file? Perhaps there is some setting there that I'm missing. – cristian Aug 21 '19 at 05:04

Ah, I think I know the issue. I didn't realize your function was a view (returning a response), I assumed it was a utility function. I've updated my answer to return a response object instead of plain text. See if that works. – Nikolas Stevenson-Molnar Aug 21 '19 at 23:31
Oh..I should have known that :) Yes, this works now ! Thanks. – cristian Aug 22 '19 at 06:06

Have you set your STATIC_URL in settings.py? You can do this by the following:

STATIC_URL = '/static/'

Your image would then be found under 'your_app/static/base/images/course/website-46-2.jpg'.

Does the folder structure follow this convention? If not you can set the STATIC_URL to '/base/'

Yes I have that setup, STATIC_URL = '/static/' – cristian Aug 20 '19 at 16:35
Actually my app is called "base" and my effective path to the image is: "project_name\base\static\base\images\course\website-46-2.jpg" – cristian Aug 20 '19 at 16:40
Have you tried `html = Template('{% load static %}')` – colonelrascals Aug 20 '19 at 16:47
Doesn't work either, gives and odd result on the page: '> – cristian Aug 20 '19 at 17:08

def startchat(request):
   template=loader.get_template('app1/chatbot.html')
   return HttpResponse(template.render())

This function loads the html page into Django. Before that , we need to import the module

from django.template import loader
