Returning data objects in views

JsonResponse

If you want to extend your views to work with ajax you may choose to return json data in your response. To make this easier you can use JsonResponse found in ajaxtoolkit.http:

from ajaxtoolkit.http import JsonResponse

class MyView(TemplateView):

    def get(self, request, *args, **kwargs):
        if request.is_ajax:
            context = self.get_context_data()
            return JsonResponse(context)
        # ...

This will set the correct mimetype (application/json) and serialise your context data into a json object.

MsgpackResponse

MsgpackResponse works in a similar way to JsonResponse, but uses msgpack to provide with binary serialisation. The usage is the same as with JsonResponse:

def get(self, request, *args, **kwargs):
    if request.is_ajax:
        context = self.get_context_data()
        return MsgpackResponse(context)
    # ...

Ajax Middleware

If you’re using Django’s messages framework, you can also add ajaxtoolkit.middleware.AjaxMiddleware in your middleware.

This will inject all messages generated in your request into your JsonResponse object:

from django.contrib import messages
from ajaxtoolkit.http import JsonResponse

class MyView(TemplateView):

    def get(self, request, *args, **kwargs):
        if request.is_ajax:
            context = self.get_context_data()

            messages.info(request, "This is very useful")
            messages.warning(request, "Be careful!")

            return JsonResponse(context)
        # ...

This would be rendered as the following:

{
    //...
    'django_messages': [
        {"extra_tags": "info",
         "message": "This is very useful",
         "level": 20},
        {"extra_tags": "warning",
         "message": "Be careful!",
         "level": 30}
    ]
}

Bypassing the message middleware

If you want to send an http response without attaching messages you can do that by setting the message_support attribute of the response object:

context = self.get_context_data()

response = JsonResponse(context)
response.message_support = False

return response

You can also choose to subclass the original response classes, eg.:

class MsgpackResponseWithoutMessages(MsgpackResponse):
    message_support = False

# ...
