ActiveModel ForbiddenAttributesError

Question

請幫幫我。 Rails發誓...我應該改變什么？ 我允許所有參數（permit_params），但這無濟於事：

ActiveModel::ForbiddenAttributesError

Extracted source (around line #17):          
@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

“ config.action_controller.permit_all_parameters = true”解決了該問題。 但是我不想禁用strong_parameters。

更新

app / admin / user.rb

ActiveAdmin.register User do

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

permit_params :authenticity_token, :commit, :id, user: [:email, :password, :password_confirmation, :superadmin]

end

附言我從事本指南工作 。 問題與該問題非常相似： 使用Active Admin和Devise會收到ActiveModel :: ForbiddenAttributesError當在管理面板ActiveAdmin中創建新用戶時，會出現此錯誤。

我必須同意您所參考問題的答案， 根據文檔，請嘗試：

permit_params :email, :password, :password_confirmation, :superadmin
