我有user_session_controller。在這裏，我使用了authlogic gem和'omniauth-facebook'gem。我希望該用戶可以在我的網站上使用Facebook登錄。我是全新的。請指導我如何修改此代碼以用Facebook登錄。用臉書authlogic和omniauth-facebook登錄
def create
@user_session = UserSession.new(params[:user_session],true)
if @user_session.save
flash[:notice] = "Login successful!"
unless cookies[:last_visited].nil?
set_last_visited
end
cookies.permanent[:last_visited] = Time.now
if params[:remember_me]
user = @user_session.user
user.update_attributes(:remember_token => create_remember_token)
cookies[:remember_token] = { :value => user.remember_token, :expires => 24.weeks.from_now }
end
redirect_back_or_default users_url(@current_user)
else
flash[:error]="invalid login and password"
render :action => :new
end
end
