Passing random url params to OmniAuth

Question

I'm using omniauth with devise and I'm wondering how to pass url params and access them.

Here's a link example: /accounts/auth/facebook?do_something_after_return=1 Now I want to be able to retrieve this do_something_after_return in the callback. I don't care if it's saved in session or elsewhere. Problem is, I don't know where can I intercept this param.

What is the controller and the action that link /accounts/auth/facebook points to? Routes tell me nothing, it's simply not there. All I have in the routes is this /accounts/auth/:provider(.:format {:controller=>"accounts/omniauth_callbacks", :action=>"passthru"} which is a callback.

Params are captured in env["omniauth.params"].

I am able to do it without the env. I can access them directly through the params hash. – Robbie Guilfoyle Aug 15 '14 at 17:57
Where is this documented? – Adam Spiers Nov 09 '19 at 23:27
