Navigation Setup

When using Fae’s installer and generators, navigation items to the objects you create will automatically get added to the side nav of the admin. Behind the scenes the generator is updating app/models/concerns/fae/navigation_concern.rb. However, this file is available for you to customize the nav however you like.

Updating navigation_concern.rb

To define your own navigation structure you just need to update the structure method within app/models/concerns/fae/navigation_concern.rb. Here’s a look at an example:

def structure
  [
    item('Products', subitems: [
      item('Apparel', class: 'custom-class', path: admin_apparel_path),
      item('Beverage', subitems: [
        item('Wines', subitems: [
          item('Releases', path: admin_releases_path)
        ]),
        item('Board Games', path: admin_board_games_path)
      ]),
    ]),
    item('Pages', subitems: [
      item('Home', path: fae.edit_content_block_path('home')),
      item('About Us', path: fae.edit_content_block_path('about_us'))
    ])
  ]
end

structure is an array of nav items which are defined with the item method. The item method takes a title as the first argument, followed by a hash of options. To nest subitems within an item, pass an array of items into the subitems option.

item(title, options = {})

Option	Type	Description
path	string or named route*	the link’s href (defaults to ‘#’)
class	string	a custom class that gets added to the link
subitems	array of items	nested links to be displayed in a dropdown

* if you want to access a named route that exists in Fae, call the named route on the fae object.

fae.pages_path

Top/Side Nav Hierarchy

The first and second level of structure defines the main nav and dropdown items respectively. When you click into a section that has third and/or fourth levels, a side nav will appear to display those items.

def structure
  [
    item('Top nav item', subitems: [
      item('Top nav dropdown item', subitems: [
        item('Side nav item', subitems: [
          item('Side nav nested item', path: '#')
        ])
      ]),
    ])
  ]
end

If the main nav dropdown doesn’t have a defined path, it will search the subitems for the first available path to link to.

Items with no subitems or active path will be removed from the navigation altogether.

Note: the side nav is hidden in forms by design, this removes clutter and allows the user to focus on the content of that object.

Dynamic Content in the Navigation

Dynamic content can be defined in navigation_concern.rb. Here’s an example:

module Fae
  module NavigationConcern
    extend ActiveSupport::Concern

    def structure
      [
        item('Teams', subitems: team_subitems)
        # scaffold inject marker
      ]
    end

    private

    def team_subitems
      teams_arr = [ item('Team List', path: admin_teams_path) ]
      Team.all.each do |team|
        teams_arr << item(team.name, subitems: [
          item('Coaches', path: admin_team_coaches_path(team)),
          item('Players', path: admin_team_players_path(team))
        ])
      end
      teams_arr
    end
  end
end
