Question

I am using django 1.4. I am moving codes from tornado to django. There is self.write() at the end of a class. What ‘s the alternative solution to self.write()？ HttpResponse? There is only one template page
so Do I need to response to other page? can I just call response？ or render_to_response to the template page again to wrape data to the page? Is write() same with HttpResponse()?
Hey, guys. there are many “?” above, But I only have one problem. An alternative solution of tornado’s “write()” in django.
thx for ur time.

The code in tornado looks like:

class DataHandler(tornado.web.RequestHandler):
    ...
    val = ...
    self.write(val)

Maybe in django?

def DataHandler(request):
    ...
    val = ...
    return HttpResponse(val)

Is that clear about my question?

Answer 1

HttpResponse is typically used if you wish to return non-template responses.

To render templates, use render from django.shortcuts, for example:

from django.shortcuts import render

def some_handler(request):
    context_for_template = {}
    return render(request, 'template_name.html', context_for_template)

From Tornado’s documentation, write seems to be able to automatically convert a dictionary to JSON. HttpResponse does not do that by default, you should look at Creating a JSON response using Django and Python if it is part of your use case.
