module ActiveAdmin

Note for posterity:

Here we have two core customizations on top of Formtastic. First, this allows you to build forms in the AA DSL without dealing with the HTML return value of individual form methods (hence the form_buffers object). Second, this provides an intuitive way to build has_many associated records in the same form.

This is a common set of Formtastic overrides needed to build a filter form that lets you select from a set of search methods for a given attribute.

Your class must declare available filters for this module to work. Those filters must be recognizable by Ransack. For example:

class FilterNumericInput < ::Formtastic::Inputs::NumberInput
  include FilterBase
  include FilterBase::SearchMethodSelect

  filter :equals, :greater_than, :less_than
end

Load the model as soon as it’s referenced. By that point, Rails & Kaminari will be ready

Public Class Methods

after_load(&block) click to toggle source

A callback is triggered each time (after) Active Admin loads the configuration files. This is an opportunity to hook into Resources after they’ve been loaded.

The block takes the current instance of [ActiveAdmin::Application]

Example:

ActiveAdmin.after_load do |app|
  app.namespaces.each do |name, namespace|
    puts "Namespace: #{name} loaded!"
  end
end

@param [Block] block A block to call each time (after) AA loads resources

# File lib/active_admin.rb, line 113
def after_load(&block)
  ActiveAdmin::Event.subscribe ActiveAdmin::Application::AfterLoadEvent, &block
end

before_load(&block) click to toggle source

A callback is triggered each time (before) Active Admin loads the configuration files. In development mode, this will happen whenever the user changes files. In production it only happens on boot.

The block takes the current instance of [ActiveAdmin::Application]

Example:

ActiveAdmin.before_load do |app|
  # Do some stuff before AA loads
end

@param [Block] block A block to call each time (before) AA loads resources

# File lib/active_admin.rb, line 95
def before_load(&block)
  ActiveAdmin::Event.subscribe ActiveAdmin::Application::BeforeLoadEvent, &block
end

setup() { |application| ... } click to toggle source

Gets called within the initializer

# File lib/active_admin.rb, line 70
def setup
  application.setup!
  yield(application)
  application.prepare!
end
