未找到。 身份验证直通。 （设计oauth facebook）

Question

I am setting up the login/registration with facebook (devise), but as other people, I have no luck to make it working. I have read lots of posts and articles from other people and went through the settings several times, but still the same results.

When I click on the "Log in with Facebook" button, I get the message "Not found. Authentication passthru".

It has never went though the "facebook" controller action, but always through the "passthru" action.

I use: - rake v2.3.0 - rails v4.2.3 - devise v3.5.2

Thank you for any help. Miroslav

Answer 1

My issue was with routes. I was using localized urls and it was causing issues with facebook omniauth.

Instead of:

localized do
    devise_for :users, path: "auth", :controllers => {sessions: 'sessions', registrations: 'registrations', confirmations: 'confirmations', passwords: 'passwords', omniauth_callbacks: 'omniauth_callbacks'} 
end

I used:

devise_for :users, path: "auth", :controllers => {sessions: 'sessions', registrations: 'registrations', confirmations: 'confirmations', passwords: 'passwords', omniauth_callbacks: 'omniauth_callbacks'}
