缺少参数或值为空 - Rails 4 引擎
param is missing or the value is empty - Rails 4 Engine
我正在构建我的第一个模块化应用程序，我的第一个模块是帐户，我的目标是让这个模块通过 Devise 处理所有各种用户模型授权。
我的第一个用户类型是 "User"，这将是所有普通员工登录应用程序的地方”（我决定对此进行模块化，因为我有一些应用程序需要类似的需求和我可以插入的模块化东西看起来很诱人。
我的问题：
我已经创建了用户模型，但是添加了一个自定义注册控制器，如下所示。
user_registrations_controller.rb
module Account
class UserRegistrationsController < Devise::RegistrationsController
private
def sign_up_params
params.require(:account_users).permit(:email, :password, :password_confirmation)
end
def account_update_params
params.require(:account_users).permit(:email, :password, :password_confirmations, :current_password)
end
end
end
用户模型如下
module Account
class User < ActiveRecord::Base
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable, :confirmable, :lockable
end
end
当我尝试注册用户时，我在 rails 服务器上得到的输出是：
Started POST "/account/users" for ::1 at 2016-04-25 00:49:12 -0600
Processing by Account::UserRegistrationsController#create as HTML
Parameters: {"utf8"=>"✓", "authenticity_token"=>"73uo7aB0DmS/rsZRuopEFvQ3MoTv1YJjdIRishvqEdY7Y2vcrIzwp6gfmUM3fApcDz2Fer5kFA/SjhNibZOGyw==", "user"=>{"email"=>"swilson@taurenltd.com", "password"=>"[FILTERED]", "password_confirmation"=>"[FILTERED]"}, "commit"=>"Sign up"}
Completed 400 Bad Request in 1ms (ActiveRecord: 0.0ms)
最后是从更好的错误 gem 中截取的屏幕截图。

查看发送到您的控制器的参数：

表单将参数发送为 user 因为这就是 resource 和 resource_name 在设计视图中的定义。
所以相关的散列键是:user而不是:account_users。以下更改应该可以解决此问题：
params.require(:user).permit(...)
或者，您可以覆盖 form_for:
中的参数名称
form_for resource, as: 'account_user' do |f|
....
如果你走那条路，你可能想要使用 account_user 而不是 account_users，因为你是 creating/updating 一个单一的资源，而不是一个集合。
