Django Rest-Framework nested serializer order
Is there a way to order a nested serializer _set, for example order by pk or time-stamp. So basically order song_set shown in the json data below from the most reacent to the latest object created, in this case by order_by('-timestamp') or order_by('-pk').

How to display ValidationErrors to users, and not 500s?
I'm having trouble understanding how to display errors to users in Django when DEBUG = FALSE. I'm just learning Django, so I could very well be missing something obvious/simple.

Correct architecture for scaling a backend
I have 3 instance of my django app hosted on Google Compute Engine in 3 different locations around the world. I am autoscaling my app to set up more instances when the cpu is at 70%. I also have a loadbalancer set up to route traffic to a close and functioning instance. This all works fine however what I don't get is how my database is scaled along with my app, in my case I have one mysql instance that stores all the data from all instances but I am not sure how to scale it since I want the same data to be available for all instances. Having only one presents many problems such as high latency for instances accessing it from another part of the world as well as all requests going to this single mysql instance. How can I better my architecture? -
How to modify request.POST in django custom middleware?
I want to add client_id and client_secret to the django POST request. Here is how my middleware.py file looks like: class LoginMiddleware(object): def __init__(self, get_response): self.get_response = get_response # One-time configuration and initialization. def __call__(self, request): # auth_header = get_authorization_header(request) # Code to be executed for each request before # the view (and later middleware) are called. #Add Django authentication app client data to the request request.POST = request.POST.copy() request.POST['client_id'] = '12345678' request.POST['client_secret'] = '12345678' response = self.get_response(request) # Code to be executed for each request/response after # the view is called. return response Middleware is being successfully processed when I check it with a debugger.
