Devise + Omniauth: undefined method `user_omniauth_authorize_path'

I've been following the omniauth + devise integration guide for facebook and I keep getting this error when I click the link to sign in with facebook link.

undefined method `user_omniauth_authorize_path' for #<#:0x000000035ea490>

I've double checked the code in the guide and I can't seem to figure out what the issue is.

Any help would be greatly appreciated.

My gemfile:

Try running rake routes and see what the paths for omniauth are. I believe they have changed with the most recent release of devise. Try changing

<%= link_to "Sign in with Facebook", user_omniauth_authorize_path(:facebook) %>


<%= link_to "Sign in with Facebook", user_facebook_omniauth_authorize_path %>

and see if that works for you.

Apparently the helpers for the omniauth routes have changed since the rake routes command for me returned

user_facebook_omniauth_authorize   GET|POST   /users/auth/facebook(.:format)          omniauth_callbacks#passthru

and not as it was some months ago when I started the project.

user_omniauth_authorize            GET|POST   /users/auth/facebook(:provider)          omniauth_callbacks#passthru

You should also change the line

@user = User.from_omniauth(request.env["omniauth"])


@user = User.from_omniauth(request.env["omniauth.auth"])

This is what worked for me, hope this helps.
