Rails 关于 Devise 的使用问题
在注册页面，提交后报 TypeError in Devise::RegistrationsController#create nil is not a symbol
啥问题呢？
还有登陆时候，提交后没报异常，直接返回登陆页面，但是我看表里也没有记录登陆信息，用 user_signed_in? 返回 false。
# You can have the root of your site routed with "root" # just remember to delete public/index.html. root :to => 'index#index'
设置了啊
路由代码： devise_for :users,:path => "account"
控制台信息：

没有发现异常啊...
没报错，我知道的已经贴出来了。
登陆后什么都没提示又返回登陆页面，就这样。 注册页面就报： TypeError in Devise::RegistrationsController#create nil is not a symbol
user model:
#encoding: utf-8 class User < ActiveRecord::Base set_table_name "users" # Include default devise modules. Others available are: # :token_authenticatable, :encryptable, :confirmable, :lockable, :timeoutable and :omniauthable devise :database_authenticatable,:registerable,:recoverable, :rememberable, :trackable, :validatable
# Setup accessible (or protected) attributes for your model attr_accessible :email, :password, :password_confirmation, :remember_me end
基本上都是 devise 自动生成的
看了下源码 def create
resource = warden.authenticate!(:scope => resource_name, :recall => "#{controller_path}#new")
logger.debug "========================="
set_flash_message(:notice, :signed_in) if is_navigational_format?
sign_in(resource_name, resource)
respond_with resource, :location => after_sign_in_path_for(resource)
end
貌似在 resource = warden.authenticate!(:scope => resource_name, :recall => "#{controller_path}#new") 就出问题了， 后面的 debug 都不能正确输出..
重新建立一个项目试了下 始终报“Invalid email or password." email 和密码填写正确也报这个..数据库我看也查询了，不过只查询的 email，条件中没加入密码..不知道哪里还配置错误
哈哈哈，已经解决。 1) TypeError in Devise::RegistrationsController#create nil is not a symbol
该错误在登陆或注册时候遇到，我把 users 表删除重新建解决，奇怪。
2) 之前说登陆后一直跳回原来页面 自己的问题，该表中有 password 字段，用来存放明文，后来试验 devise 把密码存在 encrypted_password 字段中，然后我在页面也没放
<%= notice %>
<%= alert %>
所以永远也不知道怎么回事..现在终于解决，谢谢各位
