我正在使用我正在使用Active Admin和Devise的应用。我已经修改了User和Admin Users表（通过迁移），以允许两个模型使用Device而不是Active Admin进行一次登录。 由于“超级用户”管理员可以登录并访问管理员活动。应用程序用户无法访问Admin Active。
当我尝试创建新用户或管理员时，我遇到的问题就出现了。我收到以下错误：
ActiveModel::ForbiddenAttributesError in Admin::UsersController#create
看起来很简单，但我看不到它。这是代码：
Schema.rb
ActiveRecord::Schema.define(version: 20140721134754) do
create_table "active_admin_comments", force: true do |t|

end

end
add_index "users", ["email"], name: "index_users_on_email", unique: true
add_index "users", ["reset_password_token"], name: "index_users_on_reset_password_token", unique: true
end
应用/ admin.user.rb
问题发生在第3行create_or_edit＆gt;＆gt; @user.attributes = params[:user].delete_if do |k, v|
ActiveAdmin.register User do
def registration_params
params.require(:user).permit(:email, :password, :password_confirmation, :superadmin)
end
index do
column :email
column :current_sign_in_at
column :last_sign_in_at
column :sign_in_count
actions
end
form do |f|
f.inputs "User Details" do
f.input :email
f.input :password
f.input :password_confirmation
f.input :superadmin, :label => "Super Administrator"
end
f.actions
end
create_or_edit = Proc.new {
@user = User.where(id: params[:id]).first_or_create
@user.superadmin = params[:user][:superadmin]
@user.attributes = params[:user].delete_if do |k, v|
(k == "superadmin") ||
(["password", "password_confirmation"].include?(k) && v.empty? && !@user.new_record?)
end
if @user.save
redirect_to :action => :show, :id => @user.id
else
render active_admin_template((@user.new_record? ? 'new' : 'edit') + '.html.erb')
end
}
member_action :create, :method => :post, &create_or_edit
member_action :update, :method => :put, &create_or_edit
end
如您所见，我添加了尝试解决此问题，但它不起作用。
def registration_params
params.require(:user).permit(:email, :password, :password_confirmation, :superadmin)
end
此外，我尝试了ApplicationController的解决方案，但仍然收到相同的错误消息。
def configure_permitted_parameters
devise_parameter_sanitizer.for(:sign_up) {|u| u.permit(:email, :password, :password_confirmation, :superadmin, :remember_me)}
end
我在这里缺少什么。！？
UPDATE ...

ActiveModel::ForbiddenAttributesError in Admin::UsersController#create
