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.

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up. It also means that if you are using a recently-added multiple subscription capacity, then all of the user's subscription will be ready for the month. Coupons can be set to "Once", only once (as the only name) can be used by any customer, so if this credit can earn more than once, You will have to maintain a 100% discount coupon continuousl...
