Onmiauth-Facebook 未将 facebook_id 保存到用户表中
我已经运行了bundle exec rake db:migrate并且有2个数据库。我也在开发中使用 SQLite。 当我访问 http://localhost:3000/auth/facebook 时出现以下错误：
当你没有预料到的时候，你得到了一个 nil 对象！您可能期望一个 Array 的实例。评估 nil 时发生错误。[]
它指向 app/controllers/sessions_controller.rb:12:in `create' 中的这段代码 ：
def create
auth_hash = request.env['omniauth.auth']
@authorization = Authorization.find_by_provider_and_uid(auth_hash["provider"], auth_hash["uid"])
if @authorization
render :text => "Welcome back #{@authorization.user.name}! You have already signed up."
else
######line 12-> user = User.new :name => auth_hash["user_info"]["name"], :email => auth_hash["user_info"]["email"]
user.authorizations.build :provider => auth_hash["provider"], :uid => auth_hash["uid"]
user.save
render :text => "Hi #{user.name}! You've signed up."
end
end
我认为这意味着我的信息数组是空的，并且将我的范围缩小到数据没有保存到我的数据库中的推理范围。
顺便说一句，我正在执行以下步骤 6 http://net.tutsplus.com/tutorials/ruby/how-to-use-omniauth-to-authenticate-your-users/
I've ran bundle exec rake db:migrate and have 2 databases. I'm also using SQLite in development.
I get the following error when I go to http://localhost:3000/auth/facebook:
You have a nil object when you didn't expect it! You might have expected an instance of Array. The error occurred while evaluating nil.[]
It points to this code in app/controllers/sessions_controller.rb:12:in `create'
:
def create
auth_hash = request.env['omniauth.auth']
@authorization = Authorization.find_by_provider_and_uid(auth_hash["provider"], auth_hash["uid"])
if @authorization
render :text => "Welcome back #{@authorization.user.name}! You have already signed up."
else
######line 12-> user = User.new :name => auth_hash["user_info"]["name"], :email => auth_hash["user_info"]["email"]
user.authorizations.build :provider => auth_hash["provider"], :uid => auth_hash["uid"]
user.save
render :text => "Hi #{user.name}! You've signed up."
end
end
I think this means that my array of info is empty, and narrows me down to this reasoning that data is not being saved onto my database.
Btw, I'm on step 6 following http://net.tutsplus.com/tutorials/ruby/how-to-use-omniauth-to-authenticate-your-users/

好的。我想我明白这个例子哪里出了问题。上述站点中使用的示例使用的是先前版本的omniauth，它使用“user_info”作为哈希名称。新的 1.0 版本的omniauth 将该名称更改为“info”，并将提供者策略拆分为单独的 gem，因此您必须在 Gemfile 中单独指定它们（例如：omniauth-facebook、omniauth-twitter 等）。因此，您不再使用 Gemfile 中简单的“omniauth”gem。

Ok. I think I see where this example went awry. The example that is being used in the above site is using the previous version of omniauth, which used "user_info" as the name of the hash. The new 1.0 version of omniauth changed that name to just "info" and split the provider strategies into separate gems, so you have to specify them separately in your Gemfile (ex: omniauth-facebook, omniauth-twitter, etc). So you don't use the just plain 'omniauth' gem in the Gemfile anymore.
