Question, can you have private and protected in a single Ruby on Rails controller? If not, which one is preferred in a devise controller, or a regular controller for a model?
Thanks

If a method is private, it may be called only within the context of the calling object---it is never possible to access another object instance's private methods directly, even if the object is of the same class as the caller. For protected methods, they are accessible from objects of the same class (or children).
protected methods can be called by any instance of the defining class or its subclasses. private methods can be called only from within the calling object. You cannot access another instance's private methods directly.
The class member declared as Protected are inaccessible outside the class but they can be accessed by any subclass(derived class) of that class. Private member are not inherited in class.
private: The type or member can be accessed only by code in the same class or struct . protected: The type or member can be accessed only by code in the same class , or in a class that is derived from that class .
can you have private and protected in a single Ruby on Rails controller?
Yes, you can. Rails controllers are just classes, and classes can have any number and combination of private and protected blocks.
Use protected if you want to allow for inherited controllers to access the method. Use private if you want the method to be accessible only by the controller itself.
