Django add custom header in the shorthand render method

Question

To add in a CORS settings I can do something like this on a particular function:

def clear(request):
    # ... something
    response = HttpResponse('OK')
    response["Access-Control-Allow-Origin"] = "*"
    return response

However, I'm having difficulty adding it on the shortform render method:

def function(request):
    # how to modify the response header here?
    return render(request, 'page.html', data)

How would I update some of the headers in the render response?

Answer 1

render() method combines a given template with a given context dictionary and returns an HttpResponse object with that rendered text. Refer here .

You can store the result of the render function in a variable called as response and then set cookies to it as you would normally do.

Your view function should be

def function(request):
    response = render(request, 'page.html', data)
    response["Access-Control-Allow-Origin"] = "*"
    return response

Answer 2

render also returns an HttpResponse object:

Combines a given template with a given context dictionary and returns an HttpResponse object with that rendered text.

So you can do the exact same thing you did above on the 'raw' HttpResponse object:

def function(request):
    response = render(request, 'page.html', data)
    response["Access-Control-Allow-Origin"] = "*"
    return response
