How to correctly call a controller method from another controller?

Question

Ruby on Rails

Hello. Tell me please. How to correctly call a method from another controller.
Which option is preferable
1) make the method public through ApplicationController
2) call it by creating an object Institution::MenuRequirementsController.new.update_prices()
3) or declare the method through self, and then call it Institution::MenuRequirementsController.update_prices
Or is there another solution. Thanks

Answer 1

If the method is shared, then you can either move it to a common parent, or move it to a module/concern and connect it further in the standard way.

Answer 2

Such a task should not arise, your design approach is not correct. You can use trailblazer opertaion , dry-transaction or dry-contaioner to take some common functionality out. Everything depends on the task.
