Invalid block tag. Did you forget to register or load this tag?

Question

Getting an invalid block tag message Invalid block tag on line 2: 'out'. Did you forget to register or load this tag? but don't know why. Here's my setup:

graphs.html

{% out %}

views.py

out = 'something to say'
template = loader.get_template('viz_proj/graphs.html')
context = {
    'out' : out
} 
return HttpResponse(template.render(context, request))

settings.py

INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'viz_proj'
]

Answer 1

I think you want to try {{ out }} instead of {% out %}.
