我已经根据本教程设置了 Omniauth Facebook 身份验证: http://net.tutsplus.com/tutorials/ruby/how-to-use-omniauth-to-authenticate-your-users/
现在我尝试使用相同的用户模型而不是像本教程中那样使用单独的身份模型将其与omniauth-identity结合起来: http://railscasts.com/episodes/304-omniauth-identity?view=asciicast ,但我无法获取它才能正常工作。
这是我的initializers/omniauth.rb 文件:
Rails.application.config.middleware.use OmniAuth::Builder do
provider :facebook, 'xxxxx', 'xxxxx'
provider :identity, :fields => [:email], :model => User
end
我已将omniauth-identity 所需的“password_digest”列添加到我的用户模型/表中,并将用户模型代码
从
class User < ActiveRecord::Base
has_many :authorizations
#validates :name, :email, :presence => true
def add_provider(auth_hash)
# check if the provider already exists, so we don't add it twice
unless authorizations.find_by_provider_and_uid(auth_hash["provider"], auth_hash["uid"])
Authorization.create :user => self, :provider => auth_hash["provider"], :uid => auth_hash["uid"], :token => auth_hash["token"]
end
end
end
更改为,
class User < OmniAuth::Identity::Models::ActiveRecord
...
end
但是当我这样做时,授权中的代码创建用户和授权模型的模型无法正常工作
当用户模型从 ActiveRecord::Base 扩展时,记录创建得很好,但是当我从 OmniAuth::Identity::Models::ActiveRecord 扩展用户模型时,创建新授权时,用户模型不会存储在数据库中。
这是授权模型代码:
class Authorization < ActiveRecord::Base
belongs_to :user
validates :provider, :uid, :presence => true
def self.find_or_create(auth_hash)
unless auth = find_by_provider_and_uid(auth_hash["provider"], auth_hash["uid"])
user = User.create :name => auth_hash["info"]["name"], :email => auth_hash["info"]["email"]
auth = create :user => user, :provider => auth_hash["provider"], :uid => auth_hash["uid"], :token => auth_hash["credentials"]["token"]
end
auth
end
end
当我从 ActiveRecord::Base 扩展用户模型并尝试使用 Identity 创建新的注册时,我收到此错误:
ActiveRecord::UnknownAttributeError
unknown attribute: password
有什么方法可以使其以这种方式工作吗?我现在不知道该怎么办。
I've setup Omniauth Facebook authentication according to this tutorial: http://net.tutsplus.com/tutorials/ruby/how-to-use-omniauth-to-authenticate-your-users/
And now I'm trying to combine it with omniauth-identity using the same User model instead of a separate Identity model as in this tutorial: http://railscasts.com/episodes/304-omniauth-identity?view=asciicast , but I cannot get it to work properly.
This is is my initializers/omniauth.rb file:
Rails.application.config.middleware.use OmniAuth::Builder do
provider :facebook, 'xxxxx', 'xxxxx'
provider :identity, :fields => [:email], :model => User
end
I've added 'password_digest' column that is needed by omniauth-identity to my User model/table and changed the User model code
from
class User < ActiveRecord::Base
has_many :authorizations
#validates :name, :email, :presence => true
def add_provider(auth_hash)
# check if the provider already exists, so we don't add it twice
unless authorizations.find_by_provider_and_uid(auth_hash["provider"], auth_hash["uid"])
Authorization.create :user => self, :provider => auth_hash["provider"], :uid => auth_hash["uid"], :token => auth_hash["token"]
end
end
end
to
class User < OmniAuth::Identity::Models::ActiveRecord
...
end
but when I do that the code in the Authorization model that creates the User and the Authorization models does not work properly
When the User model extends from ActiveRecord::Base the records are created just fine but when I extend the user model from OmniAuth::Identity::Models::ActiveRecord the user model is not stored in the database when you create a new authorization.
This is the Authorization model code:
class Authorization < ActiveRecord::Base
belongs_to :user
validates :provider, :uid, :presence => true
def self.find_or_create(auth_hash)
unless auth = find_by_provider_and_uid(auth_hash["provider"], auth_hash["uid"])
user = User.create :name => auth_hash["info"]["name"], :email => auth_hash["info"]["email"]
auth = create :user => user, :provider => auth_hash["provider"], :uid => auth_hash["uid"], :token => auth_hash["credentials"]["token"]
end
auth
end
end
When I extend the User model from ActiveRecord::Base and try to create a new registration with Identity I get this error:
ActiveRecord::UnknownAttributeError
unknown attribute: password
Is there any way to get this working this way? I don't know what to do now.

不确定你是否仍然遇到这个问题,但也许 interwebz 上的某个人会遇到这个问题。
我刚刚通过博客发布了一个解决方案,应该可以解决您的问题:
http://bernardi.me/2012/09/using-multiple-omniauth-providers-with-omniauth-identity-on-the-main-user-model/
not sure you're still having the problem, but maybe someone on the interwebz will.
I just posted a solution on by blog, should solve your problems:

尝试添加 attr_accessor :password 并且可能是 attr_accessor :email
try to add attr_accessor :password and may be attr_accessor :email
