Rails / Devise（Devise令牌身份验证）在解锁帐户后重定向

Question

I'm currently trying to find a way to change my redirection url upon unlocking an account. Currently when an account is locked the user is getting a email to unlock is account but then the te user get redirect on a default url. Since my rails project is an api it would be nice to redirect to my front-end

To do any customization with Devise, one must override the default controllers by creating a new controller and inheriting from it in your case that would be Devise::UnlocksController

For example: CustomUnlocksController < Devise::UnlocksController

https://github.com/plataformatec/devise/blob/master/app/controllers/devise/unlocks_controller.rb

Override after_unlock_path_for to the path which you are going to redirect after.
