Devise Issue : TypeError – [17] is not a symbol3个
设计正在抛出一个我不明白的问题. 使用更好的错误gem;这是它被捕获的地方： constantize(gem)activesupport-3.2.12 / lib / active_support / inflector / methods.rb中的块 225 names = camel_cased_word.split('::')
226 names.shift if names.empty? || names.first.empty?
227
228 constant = Object
229 names.each do |name|
230 constant = constant.const_defined?(name,false) ?
constant.const_get(name) : constant.const_missing(name)
231 end
232 constant
233 end
234 end

有任何想法吗？更多信息有用吗？ 这是跟踪结束时的一个块： block in ActiveSupport::Inflector.constantize (gem) activesupport-3.2.12/lib/active_support/inflector/methods.rb,line 230 ActiveSupport::Inflector.constantize (gem) activesupport-3.2.12/lib/active_support/inflector/methods.rb,line 229 Warden::SessionSerializer#deserialize (gem) devise-2.2.3/lib/devise/rails/warden_compat.rb,line 27 Warden::SessionSerializer#fetch (gem) warden-1.2.1/lib/warden/session_serializer.rb,line 35 Warden::Proxy#user (gem) warden-1.2.1/lib/warden/proxy.rb,line 212 Warden::Proxy#_perform_authentication (gem) warden-1.2.1/lib/warden/proxy.rb,line 318 Warden::Proxy#authenticate (gem) warden-1.2.1/lib/warden/proxy.rb,line 104 Warden::Proxy#authenticate?

我从2.0.4更新到2.2.4,当我用旧版本更改为项目的稳定分支时发生这种情况.解决方案是清除浏览器中我的localhost的所有cookie.在您的情况下,您将运行您的应用程序的服务器.
