Get a username when using Devise and Omniauth

Hello everyone o/

I’m currently building a Rails app and I’m using Devise
https://github.com/plataformatec/devise and Omniauth
https://github.com/intridea/omniauth (Google OAuth2 and Facebook) for
authentication. All users are going to have unique usernames. This is
not a
problem when I’m using just a form, but when the users tries to sign up
using Omniauth, I can’t get a username that I can ensure is unique and
fits
the criteria I’ve made for a valid username. If I do try to sign up with
it, it just redirects to the form that regular users would use to sign
up.

I’ve thought about redirecting the user to a separate page where they
create a username, but I don’t know how I would go about this. Searching
the internet has not yielded any results either.

Does anyone know how I could accomplish this? I’m open to any ideas.

Thanks :slight_smile:

One way I’ve done similar things is by overriding
‘after_sign_in_path_for’.
See the Devise docs for an example:

https://github.com/plataformatec/devise/wiki/How-To:-redirect-to-a-specific-page-on-successful-sign-in#redirect-back-to-current-page-after-oauth-signin

Based on the requirements you’ve described, one option would be to check
on
sign-in to see if a user has no username and redirect them to a page
that
requests one. Your DB models may require some work to make it possible
to
create a “user” with an empty username.
