Omniauth “with” STI and devise

问题

I'm figured out with no results. I have a model named User and to models with STI fan and artist, like this:

class User < ActiveRecord::Base
    devise :database_authenticatable, :registerable, :confirmable, :lockable,
     :recoverable, :rememberable, :trackable, :validatable, **:omniauthable**
end

and my others models

Class Artist < User end
Class Fan < User end

my routes

devise_for :users
devise_for :artists
devise_for :fans

I have a problem when try to run my server or anything else i got this error

Wrong OmniAuth configuration. If you are getting this exception, it means that either:

1) You are manually setting OmniAuth.config.path_prefix and it doesn't match the Devise one
2) You are setting :omniauthable in more than one model
3) You changed your Devise routes/OmniAuth setting and haven't restarted your server

my app is advanced and don't wanna go back and refactor it, any help will appreciate

The answer can be found here.

Devise gets mixed up since you are calling devise_for for three different models and one of them is using the omniauthable module.

Either:

Remove all devise_for methods except for :users.
Or remove the omniauthable module from the user model, create your own omniauth routes and stop using devise's middleware by moving your omniauth configuration into a new file. So, instead of having this in devise.rb:
```
Devise.setup do |config|
  config.omniauth :twitter, ENV['TWITTER_KEY'], ENV['TWITTER_SECRET']
end
```
You now have this in your new file omniauth.rb:
```
Rails.application.config.middleware.use OmniAuth::Builder do
  provider :twitter, ENV['TWITTER_KEY'], ENV['TWITTER_SECRET']
end
```
The Railscast on Simple OmniAuth should help you setting this up.
