+  # Active Admin will automatically call an authentication
+  # method in a before filter of all controller actions to

+  # This setting changes the method which Active Admin calls

+
+  # In case you prefer Pundit over other solutions you can here pass
+  # the name of default policy class. This policy will be used in every
+  # case when Pundit is unable to find suitable policy.
+  # config.pundit_default_policy = "MyDefaultPunditPolicy"
+
+  # You can customize your CanCan Ability class name here.
+  # config.cancan_ability_class = "Ability"
+
+  # You can specify a method to be called on unauthorized access.
+  # This is necessary in order to prevent a redirect loop which happens
+  # because, by default, user gets redirected to Dashboard. If user
+  # doesn't have access to Dashboard, he'll end up in a redirect loop.
+  # Method provided here should be defined in application_controller.rb.
+  # config.on_unauthorized_access = :access_denied
+
+  # == Current User
+  #
+  # Active Admin will associate actions with the current
+  # user performing them.
+  #
+  # This setting changes the method which Active Admin calls
+  # (within the application controller) to return the currently logged in user.
+  # config.current_user_method = :current_admin_user
+
+  # == Logging Out
+  #
+  # Active Admin displays a logout link on each screen. These
+  # settings configure the location and method used for the link.
+  #
+  # This setting changes the path where the link points to. If it's
+  # a string, the strings is used as the path. If it's a Symbol, we
+  # will call the method to return the path.
+  #
+  # Default:
+  config.logout_link_path = :destroy_admin_user_session_path
+
+  # This setting changes the http method used when rendering the
+  # link. For example :get, :delete, :put, etc..
+  #
+  # Default:
+  # config.logout_link_method = :get
+
+  # == Root
+  #
+  # Set the action to call for the root path. You can set different
+  # roots for each namespace.
+  #
+  # Default:
+  # config.root_to = 'dashboard#index'
+
+  # == Admin Comments
+  #
+  # This allows your users to comment on any resource registered with Active Admin.
+  #
+  # You can completely disable comments:
+  # config.comments = false
+  #
+  # You can disable the menu item for the comments index page:
+  # config.show_comments_in_menu = false
+  #
+  # You can change the name under which comments are registered:
+  # config.comments_registration_name = 'AdminComment'
+
+  # == Batch Actions
+  #
+  # Enable and disable Batch Actions
+  #
+  config.batch_actions = true
+
+  # == Controller Filters
+  #
+  # You can add before, after and around filters to all of your
+  # Active Admin resources and pages from here.
+  #
+  # config.before_filter :do_something_awesome
+
+  # == Setting a Favicon
+  #
+  # config.favicon = 'favicon.ico'
+
+  # == Removing Breadcrumbs
+  #
+  # Breadcrumbs are enabled by default. You can customize them for individual
+  # resources or you can disable them globally from here.
+  #
+  # config.breadcrumb = false
+
+  # == Register Stylesheets & Javascripts
+  #
+  # We recommend using the built in Active Admin layout and loading
+  # up your own stylesheets / javascripts to customize the look
+  # and feel.
+  #
+  # To load a stylesheet:
+  #   config.register_stylesheet 'my_stylesheet.css'
+  #
+  # You can provide an options hash for more control, which is passed along to stylesheet_link_tag():
+  #   config.register_stylesheet 'my_print_stylesheet.css', media: :print
+  #
+  # To load a javascript file:
+  #   config.register_javascript 'my_javascript.js'
+
+  # == CSV options
+  #
+  # Set the CSV builder separator
+  # config.csv_options = { col_sep: ';' }
+  #
+  # Force the use of quotes
+  # config.csv_options = { force_quotes: true }
+
+  # == Menu System
+  #
+  # You can add a navigation menu to be used in your application, or configure a provided menu
+  #
+  # To change the default utility navigation to show a link to your website & a logout btn
+  #
+  #   config.namespace :admin do |admin|
+  #     admin.build_menu :utility_navigation do |menu|
+  #       menu.add label: "My Great Website", url: "http://www.mygreatwebsite.com", html_options: { target: :blank }
+  #       admin.add_logout_button_to_menu menu
+  #     end
+  #   end
+  #
+  # If you wanted to add a static menu item to the default menu provided:
+  #
+  #   config.namespace :admin do |admin|
+  #     admin.build_menu :default do |menu|
+  #       menu.add label: "My Great Website", url: "http://www.mygreatwebsite.com", html_options: { target: :blank }
+  #     end
+  #   end
+
+  # == Download Links
+  #
+  # You can disable download links on resource listing pages,
+  # or customize the formats shown per namespace/globally
+  #
+  # To disable/customize for the :admin namespace:
+  #
+  #   config.namespace :admin do |admin|
+  #
+  #     # Disable the links entirely
+  #     admin.download_links = false
+  #
+  #     # Only show XML & PDF options
+  #     admin.download_links = [:xml, :pdf]
+  #
+  #     # Enable/disable the links based on block
+  #     #   (for example, with cancan)
+  #     admin.download_links = proc { can?(:view_download_links) }
+  #
+  #   end
+
+  # == Pagination
+  #
+  # Pagination is enabled by default for all resources.
+  # You can control the default per page count for all resources here.
+  #
+  # config.default_per_page = 30
+
+  # == Filters
+  #
+  # By default the index screen includes a "Filters" sidebar on the right
+  # hand side with a filter for each attribute of the registered model.
+  # You can enable or disable them for all resources here.
+  #
+  # config.filters = true
+end
