  enum status: [:draft, :review, :published, :moderate]

  friendly_id :title, use: :slugged
  acts_as_paranoid
  after_initialize :set_default_status, :if => :new_record?

  scope :latest, -> { order(time_start: :asc) }
  scope :status_draft, -> { where(status: Ad.statuses[:draft]) }
  scope :status_published, -> { where(status: Ad.statuses[:published]) }
  scope :current_displayed, -> { where('time_start < ? AND time_end > ?', Time.now, Time.now) }

  scope :show_active, -> { status_published.latest.current_displayed }
  scope :show_draft, -> { status_draft.latest.current_displayed }

  def should_generate_new_friendly_id?
    slug.blank? || title_changed?

  def set_default_status
    self.status ||= :draft
  end

  def related
    category.ads.where.not(id: id).show_active.limit(6)

  ## == Gravatar integration ==
  ## To disable Gravatar integration in Navigation Bar set to false
  # config.show_gravatar = true

  config.parent_controller = 'ApplicationController'

  config.actions do
    dashboard                     # mandatory
    index                         # mandatory
    new

    edit
    delete
    show_in_app

    ## With an audit adapter, you can add:
    # history_index
    # history_show
  end

  # config.model 'Ad' do
    # list do
      # field :title
      # field :created_at

cancancan ability file

# frozen_string_literal: true

class Ability
  include CanCan::Ability

  def initialize(user)
    # Define abilities for the passed in user here. For example:
    #
    user ||= User.new # guest user (not logged in)
    if user.admin?
      can :access, :rails_admin
      can :manage, :all
    end
    #
    # The first argument to `can` is the action you are giving the user
    # permission to do.
    # If you pass :manage it will apply to every action. Other common actions
    # here are :read, :create, :update and :destroy.
    #
    # The second argument is the resource the user can perform the action on.
    # If you pass :all it will apply to every resource. Otherwise pass a Ruby
    # class of the resource.
    #
    # The third argument is an optional hash of conditions to further filter the
    # objects.
    # For example, here the user can only update published articles.
    #
    #   can :update, Article, :published => true
    #

I dont do any fancy config setup for rails_admin and ad.rb model. This happens in development environment and production. I think this is because rails_admin hide something i dont know. I dont know what to do.

Answer 1

I solved this by renaming "Ad" model to "Item"
