您好，我目前正在关注为我的webapp添加Facebook身份验证的railscast 360。它是一切正常，直到我开始收到此错误：SessionsController中的NoMethodError＃使用Omniauth Facebook身份验证创建railscast 360
"NoMethodError in SessionsController#create
undefined method `name=' for #"
app/models/user.rb:6:in
block in from_omniauth' app/models/user.rb:3:intap' app/models/user.rb:3:infrom_omniauth' app/controllers/sessions_controller.rb:3:increate'
我已经看过这个网站，但他们中的很多在几个不同的答案似乎是Twitter的认证，我只是试图让Facebook的加工。
我已经在Facebook Developers上创建了一个应用程序，并完全遵循了轨道演员教程。我非常感谢这方面的帮助。
到目前为止我的代码是
user.rb：
class User < ActiveRecord::Base
def self.from_omniauth(auth)
where(auth.slice(:provider, :uid)).first_or_initialize.tap do |user|
user.provider = auth.provider
user.uid = auth.uid
user.name = auth.info.name
user.oauth_token = auth.credentials.token
user.oauth_expires_at = Time.at(auth.credentials.expires_at)
user.save!
end
end
end
application_controller.rb
class ApplicationController < ActionController::Base
protect_from_forgery
private
def current_user
@current_user ||= User.find(session[:user_id]) if session[:user_id]
rescue ActiveRecord::RecordNotFound
end
helper_method :current_user
end
session_controller.rb
class SessionsController < ApplicationController
def create
user = User.from_omniauth(env["omniauth.auth"])
session[:user_id] = user.id
redirect_to root_url
end
def destroy
session[:user_id] = nil
redirect_to root_url
end
end
这是我的我的application.html.erb内部代码：
<div id="user_nav">
<% if current_user %>
Signed in as <strong><%= current_user.name %></strong>!
<%= link_to "Sign out", signout_path, id: "sign_out" %>
<% else %>
<%= link_to "Sign in with Facebook", "/auth/facebook", id: "sign_in" %>
<% end %>
会很感激的任何帮助。
感谢
