I am new to Ruby. I have a below code in my controller. Desired Behaviour :- I want to display validation error string to my views on edit page. So I am putting those errors in a variable. When validation fails then I want to use that variable in my edit method, so that I can display that on my edit page view.
Observed behaviour :- There is a variable @vpinerr in create method. I wan to use that variable in edit method. I have tried to use the class variable (@@vpinerr) and initialized it with an empty string (@@vpinerr = "") then the value of this variable becomes empty in edit method.
