Using render() with Form?

[Victor Hooi]

heya,

I was previously using the following to render a form:

from django.shortcuts import render_to_response, RequestContext

...

def upload_file(request):

...

return render_to_response('upload_form.html', {'form': form}, context_instance=RequestContext(request))

I can confirm that this works fine, form was rendered perfectly fine.

However, I read that render() is now the bee-knees...lol (http://stackoverflow.com/questions/5154358/django-what-is-the-difference-between-render-render-to-response-and-direct), so I thought I'd switch to that:

from django.shortcuts import render
...
def upload_file(request):
...
return render('upload_form.html', {'form': form})

However, when I try to do that, I get an error:

Any idea from the above why this might be happening?

Thanks,

The first argument to `render` is the request.

"render" requires as its first argument the request object supplied to your view function. So, your example should be:

def upload_file(request):
...
return render(request, 'upload_form.html', {'form': form})

heya,

Aha, thanks guys. I can confirm that works fine now.

That'll teach me to read the API docs a bit better...lol, I just assumed it was a 1-to-1 swap with render_to_response, didn't check the arguments =).

Cheers,

Victor
