Devise + Omniauth: undefined method `user_omniauth_authorize_path'
devise, facebook, ruby-on-rails
Solution
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) %>
to
<%= 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"])
to
@user = User.from_omniauth(request.env["omniauth.auth"])
This is what worked for me, hope this helps.
Problem
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 `#<#<Class:0x0000000253a550>:0x000000035ea490>` I've double checked the code in the guide and I can't seem to figure out what the issue is.
