如何从omniauth获取facebook的时区？
user.rb中的所有内容在注册时正确传递，时区除外。 我无法弄清楚为什么我在尝试登录时遇到此错误 ：
2016-03-30T20:13:38.083469+00:00 app[web.1]: NoMethodError (undefined method `timezone=' for #): 2016-03-30T20:13:38.083470+00:00 app[web.1]: app/models/user.rb:72:in `block in from_omniauth' 2016-03-30T20:13:38.083471+00:00 app[web.1]: app/models/user.rb:66:in `tap' 2016-03-30T20:13:38.083471+00:00 app[web.1]: app/models/user.rb:66:in `from_omniauth' 2016-03-30T20:13:38.083472+00:00 app[web.1]: app/controllers/sessions_controller.rb:7:in `facebook' user.rb
def self.from_omniauth(auth) # Sets 60 day auth token oauth = Koala::Facebook::OAuth.new("1540371223342976229929", "ee917abf2e8f1c98274cd323fa1234ebb1346f4") # Fake Numbers new_access_info = oauth.exchange_access_token_info auth.credentials.token new_access_token = new_access_info["access_token"] new_access_expires_at = DateTime.now + new_access_info["expires"].to_i.seconds where(provider: auth.provider, uid: auth.uid).first_or_initialize.tap do |user| user.provider = auth.provider user.image = auth.info.image user.uid = auth.uid user.name = auth.info.first_name user.last_name = auth.info.last_name user.timezone = auth.info.timezone user.email = auth.info.email unless user.email.present? user.oauth_token = new_access_token # auth.credentials.token <- your old token. Not needed anymore. user.oauth_expires_at = Time.at(auth.credentials.expires_at) user.password = (0...8).map { (65 + rand(26)).chr }.join user.activated = true user.save! end end
配置/ omniauth.rb
Rails.application.config.middleware.use OmniAuth::Builder do provider :facebook, "1540324372976229929", "ee917abf2e8423f1c98274cdfa234234ebb1346f4", {info_fields: 'email, first_name, last_name, timezone'} end
t.float "timezone" Facebook文档称时区应该是float 。
看起来omniauth提供的auth哈希结构与您使用的结构略有不同。 试试这个。
user.timezone = auth.extra.raw_info.timezone
这是 Facebook omniauth可用的哈希结构 。
