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

{% extends "name" %} ?

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'

That's probably something like this (invalid view): stackoverflow.com/questions/43987462/…

Not likely because I have a view like this: course( request, question_id ) and it's working without the suggested code.

Which version of Django are you using and which line is causing the exception? This works for me on Django 1.11.

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.

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 Over a year ago

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"

Have you tried html = Template('{% load static %}<IMG SRC="{% static "base/images/course/website-46-2.jpg" %}">')

cristian Over a year ago

Doesn't work either, gives and odd result on the page: '>

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
