Linked part of the code into a method. but it has a session, that is, it is impossible in Model, in Helper? or can be somehow more orthodox?

Question

Ruby on Rails

That is, purely in the controller, I don’t want to keep it as many lines of code and it contains redis, but there are sessions there and it doesn’t allow it into the model.

Answer 1

In my opinion, the most adequate solution is to pass the session as a parameter to the model method.
If only a specific value from the session is used, it is better to pass it, rather than the entire session.
And, if you then need to change this value in the session to a new one, you should return it from the model method to the controller and assign it in the controller.
