Making Django's CBV's get an instance method

Question

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?

Answer 1

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.
