rails-admin

问题 I am having: class Entity < AR::Base has_many :representatives, inverse_of: :entity, dependent: :destroy accepts_nested_attributes_for :representatives, allow_destroy: true end and the Entity's rails admin form allows me to create nested representatives inline.

问题 I mounted in my app the RailsAdmin engine ( according to the instructions from the wiki ) using mount RailsAdmin::Engine => '/backend', :as => 'rails_admin' I had to extend one controller from the engine to add a before_filter.

问题 In my rails 4 app I'm using paranoia to soft delete users and rails_admin for admin interface. Currently in rails_admin after deleting a record it doesn't show deleted records. I want to see all records in rails_admin where deleted records are marked differently and create a custom action to restore deleted records. Thanks! 回答1: You now have deleted scope on your model.

问题 I am using rails_admin in my app. I have some scopes on my models, following is an example: class User < ActiveRecord::Base scope :unconfirmed, where('confirmed_at IS NULL') end Is it possible in rails_admin to get access to those scope as a filter?
