How To: Create a Dashboard Interface

Create a new app/admin/dashboard_admin.rb file and add the following contents:

Trestle.admin(:dashboard) do
  menu do
    item :dashboard, icon: "fa fa-tachometer"
  end

  controller do
    def index
      @missing_warhead_count = Warhead.missing.count
    end
  end
end

Note that we are configuring a Trestle.admin and not a Trestle.resource.

Then add a view to support it at app/views/admin/dashboard/index.html.haml:

- content_for(:title, 'Dashboard')
= render "header"

.main-content-area
  .main-content-container
    .main-content
      %h3= pluralize(@missing_warhead_count,'Missing Warhead')
