ImportError cannot import name render to response from django shortcuts

0 votes

After upgrading to Django 3.0, I get the following error:

ImportError: cannot import name 'render_to_response' from 'django.shortcuts'

My view:

from django.shortcuts import render_to_response

from django.template import RequestContext

def index(request):
    context = {'foo': 'bar'}
    return render_to_response('index.html', context, context_instance=RequestContext(request))

Here is the full traceback:

Hello @kartik,

The render_to_response shortcut was deprecated in Django 2.0, and is removed in Django 3.0. You can use the render shortcut instead, which was added way back in Django 1.3. The render shortcut works similarly to render_to_response, but takes request as its first argument. Change your view as follows:

from django.shortcuts import render

def index(request):
    context = {'foo': 'bar'}
    return render(request, 'index.html', context) 

In your view, you have context_instance=RequestContext(request) as the third argument. This was deprecated in Django 1.8, and does not work in Django 1.10+.

If you are using render_to_response without context_instance, then you can pass None as the request to the render shortcut. For example, if you have,

return render_to_response('index.html', context)

then the equivalent with render is:

return render(None, 'index.html', context)

Hope it helps!!
