我想配置谷歌的OAuth和我面臨着一個非常愚蠢的錯誤我解決不了： 當我在按鈕點擊登錄主頁上：未定義模型方法4
<% if user_signed_in? %>
Signed in as <%= current_user.name %>. Not you?
<%= link_to "Sign out", destroy_user_session_path,:method => :delete %>
<% else %>
<%= link_to "Sign in with Google", user_omniauth_authorize_path(:google_oauth2) %>
<% end %>
我得到這個錯誤未定義的方法find_for_google_oauth2爲＃
它說，這個問題是在該行： @user = user.find_for_google_oauth2(request.env["omniauth.auth"], current_user)
這裏是我的app/controllers/users/omniauth_callbacks_controller.rb：
class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
def facebook
# You need to implement the method below in your model (e.g. app/models/user.rb)
@user = User.from_omniauth(request.env["omniauth.auth"])
if @user.persisted?
sign_in_and_redirect @user, :event => :authentication #this will throw if @user is not activated
set_flash_message(:notice, :success, :kind => "Facebook") if is_navigational_format?
else
session["devise.facebook_data"] = request.env["omniauth.auth"]
redirect_to new_user_registration_url
end
end
def google_oauth2
@user = User.find_for_google_oauth2(request.env["omniauth.auth"], current_user)
if @user.persisted?
flash[:notice] = I18n.t "devise.omniauth_callbacks.success", :kind => "Google"
sign_in_and_redirect @user, :event => :authentication
else
session["devise.google_data"] = request.env["omniauth.auth"]
redirect_to new_user_registration_url
end
end
end這裏是我的應用程序/模型/ user.rb：
