ruby on rails - Can I replace class variables with class instance variables in Simple Form gem? -


For stylish reasons, I would like to avoid using class variables and would like to change them with a class instance variables. So if I have: 

  module SimpleForm mattr_accessor: input_error_class @@ input_error_class = 'error-field' ... end   
 and I change it in I:    Module SimpleForm @input_error_class = 'Error Field' Category & lt; & Lt; Self attr_accessor: input_error_class end ... end   
 Will this break a simple form?   
 
 
 If there is a class that is a sub-class or  SimpleForm  Superclass, then the shared code is  @@ input_error_class , then by changing the class instance to the class instance variable, the variable will no longer be shared by sub / superclass, and it can break the code Also, If there is an example method that uses class variables, which can break the code. Otherwise, it does not break.
