If you have data you want on a standalone page that isn't tied to a resource, custom pages provide you with a familiar syntax and feature set:
- a menu item
- action items
- page actions
Create a new Page
Creating a page is as simple as calling
# app/admin/calendar.rb .register_page "Calendar" do content do para "Hello World" end end
Anything rendered within
content will be the main content on the page.
Partials behave exactly the same way as they do for resources:
# app/admin/calendar.rb .register_page "Calendar" do content do render partial: 'calendar' end end # app/views/admin/calendar/_calendar.html.arb table do thead do tr do %w[Sunday Monday Tuesday Wednesday Thursday Friday Saturday].each &method(:th) end end tbody do # ... end end
Customize the Menu
See the Menu documentation.
Customize the breadcrumbs
.register_page "Calendar" do do ['admin', 'calendar'] end end
Customize the Namespace
We use the
admin namespace by default, but you can use anything:
# Available at /today/calendar .register_page "Calendar", namespace: :today # Available at /calendar .register_page "Calendar", namespace: false
Add a Sidebar
See the Sidebars documentation.
Add an Action Item
Just like other resources, you can add action items. The difference here being that
:except don't apply because there's only one page it could apply to.
action_item :view_site do "View Site", "/" end
Add a Page Action
Page actions are custom controller actions (which mirror the resource DSL for the same feature).
page_action :add_event, method: :post do # ... redirect_to admin_calendar_path, notice: "Your event was added" end action_item :add do "Add Event", admin_calendar_add_event_path, method: :post end
This defines the route
/admin/calendar/add_event which can handle HTTP POST requests.
Clicking on the action item will reload page and display the message "Your event was added"
