Rails 设计+omniauth-google-oauth2

Question

I am trying to implement login from google in my rails app.I am following instructions from README file at github page of the "omniauth-google-oauth2" LINK .I am trying to use the name parameter in devise.rb config file so that links are from "google" and not "google_oauth2".
So i have added:

config.omniauth :google_oauth2, "GOOGLE_CLIENT_ID", "GOOGLE_CLIENT_SECRET", { name: "google" }

But in the bottom links of devise views the link is still

http://localhost:3000/users/auth/google_oauth2 

but clicking on this link gives

Not found. Authentication passthru.

on page.
But now

http://localhost:3000/users/auth/google 

works.How do i fix the link?

Answer 1

config.omniauth :google_oauth2, 
                "GOOGLE_CLIENT_ID", 
                "GOOGLE_CLIENT_SECRET", 
                { name: "google" }

Works just fine to change the provider name. 2 caveats

1. Change it everywhere! Make sure your callback is using google , make sure your callback URL (in the google developer console) uses google
2. Restart your server - because it's in an initializer, any changes you've made won't be activated until you restart
