const RailsAdmin::Adapters::ActiveRecord missing every time I initial…

[victor95pc]

Every time I enter on a page which has a model with associations on Mongoid, I always receive a const RailsAdmin::Adapters::ActiveRecord is missing error, so digging the code I found there isn't any require for this for file rails_admin/adapters/active_record/association, after I require the file the model started loading properly.

my specs:

Rails: 5.2.1
Ruby: 2.5.3p105

This is my models

class PatternConfig
  include Mongoid::Document

  field :patern_name, type: String
  field :token,       type: String
  field :service,     type: String

  index({ patern_name: 1 }, { unique: true })

  embeds_many :patterns

  accepts_nested_attributes_for :patterns, allow_destroy: true

  rails_admin do
    edit do
      field :patern_name
      field :patterns
    end
  end
end

class Pattern
  include Mongoid::Document

  field :token,   type: String

  embedded_in :pattern_config

  rails_admin do
    edit do
      field :hour, :integer
    end
  end
end
