本文介绍了我通过Active Admin和Devise得到ActiveModel :: ForbiddenAttributesError的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在开发一个使用Active Admin和Devise的应用程序。我已经修改了User和Admin Users表（通过迁移），以允许两种模型都使用设备而不是Active Admin使用一个登录过程。
以超级用户身份Admin可以登录并访问Admin Active。应用程序用户将无法访问Admin Active。
I'm working on an app where I'm using Active Admin and Devise. I have modified both User and Admin Users table (via migration) to allow both models use one signing in process using Device instead of Active Admin.As 'super user' Admin can Sign In and access Admin Active. And application users wouldn't access Admin Active.
我遇到的问题是在尝试创建新用户或Admin时发生的。我收到以下错误：
The problem I'm face happens when I attempt to create a new user or Admin. I get the following error:
ActiveModel::ForbiddenAttributesError in Admin::UsersController#create
看似简单，但我看不到。下面是代码：
It seems like simple but I can't see it. Here is the code:
Schema.rb
ActiveRecord::Schema.define(version: 20140721134754) do
create_table "active_admin_comments", force: true do |t|
t.string "namespace"
t.text "body"
t.string "resource_id", null: false
t.string "resource_type", null: false
t.integer "author_id"
t.string "author_type"
t.datetime "created_at"
t.datetime "updated_at"
end
add_index "active_admin_comments", ["author_type", "author_id"], name: "index_active_admin_comments_on_author_type_and_author_id"
add_index "active_admin_comments", ["namespace"], name: "index_active_admin_comments_on_namespace"
add_index "active_admin_comments", ["resource_type", "resource_id"], name: "index_active_admin_comments_on_resource_type_and_resource_id"
create_table "admin_users", force: true do |t|
t.string "email", default: "", null: false
t.string "encrypted_password", default: "", null: false
t.string "reset_password_token"
t.datetime "reset_password_sent_at"
t.datetime "remember_created_at"
t.integer "sign_in_count", default: 0, null: false
t.datetime "current_sign_in_at"
t.datetime "last_sign_in_at"
t.string "current_sign_in_ip"
t.string "last_sign_in_ip"
t.datetime "created_at"
t.datetime "updated_at"
end
add_index "admin_users", ["email"], name: "index_admin_users_on_email", unique: true
add_index "admin_users", ["reset_password_token"], name: "index_admin_users_on_reset_password_token", unique: true
create_table "users", force: true do |t|
t.string "email", default: "", null: false
t.string "encrypted_password", default: "", null: false
t.string "reset_password_token"
t.datetime "reset_password_sent_at"
t.datetime "remember_created_at"
t.integer "sign_in_count", default: 0, null: false
t.datetime "current_sign_in_at"
t.datetime "last_sign_in_at"
t.string "current_sign_in_ip"
t.string "last_sign_in_ip"
t.datetime "created_at"
t.datetime "updated_at"
t.boolean "superadmin", default: false, null: false
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
app / admin.user.rb
第3行 create_or_edit >> @ 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? && [email protected]_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，我已尝试解决此问题问题，但它不起作用。
As you see I had added attempt to solve this issue but it doesn't work.
def registration_params
params.require(:user).permit(:email, :password, :password_confirmation, :superadmin)
end
我也尝试了以下解决方案 ApplicationController ，但仍会收到相同的错误消息。
Also I tried following solution for ApplicationController but still get same error message.
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？！
更新...
错误消息
ActiveModel::ForbiddenAttributesError in Admin::UsersController#create
ActiveModel::ForbiddenAttributesError
在第25行出现错误
app / admin / user.rb
22 create_or_edit = Proc.new {
23 @user = User.where(:id => params[:id]).first || User.new
24 @user.superadmin = params[:user][:superadmin]
*25 @user.attributes = params[:user].delete_if do |k, v|*
26 (k == "superadmin") ||
27 (["password", "password_confirmation"].include?(k) && v.empty? && [email protected]_record?)
28 end
29 if @user.save
30 redirect_to :action => :show, :id => @user.id
请求参数

推荐答案
为什么不像文档一样允许参数说什么
Why don't you permit your params just like the documentation says?https://github.com/gregbell/active_admin/blob/master/docs/2-resource-customization.md#setting-up-strong-parameters
