Making Django's CBV's get an instance method
As I said, get is an instance method.
But you are confusing responsibilities here. A class should have one responsibility only. The view class has the responsibility of responding to the request and returning a response; this is quite separate from the connection to the instrument. That should be a separate class, which is instantiated at module level and used within the view class.
I'm currently building a Django app which uses a singleton object.
I want to save this object as a CBV variable because I dont want to initialize it for every 'get' call.
My question in short - can you make a CBV's get function an instance method instead of a classmethod?
And if so, can I save a variable as an instance variable?
EDIT - A better explanation to my question:
I created a class that handles a serialized connection with an electronic measurment instrument.
This class must have only 1 instance (singleton), if another instance will be created a memory leak will crash python.
I want to use it with django in the following way:

Get request to a certain url address -> 
      The view will ask the instrument class instance for data->
          Instance responds with data ->
              View returns a JsonResponse with the data.

I think the best way to do it is making the CBV's get method (whose related to the url im getting from) an instance method, but its not such a good practice..
How should I do it?
