How to

Add to Gemfile

gem 'rails-settings-ui'

Setup:

# adds initializer and route:
rails g rails_settings_ui:install

Config

In config/initializers/rails_settings_ui.rb

RailsSettingsUi.setup do |config|
  config.ignored_settings = [:company_name] # Settings not displayed in the interface
end

Routing

# engine root:
rails_settings_ui_url

I18n

You can localize:

• Settings names, eg:

  settings:
    attributes:
      launch_mode: # setting name
        name: 'Launch mode'

• Checkbox or select options labels for array options, eg:

  settings:
    attributes:
      launch_mode:
        labels:
          auto: 'Auto mode'
          manual: 'Manual mode'

• Help blocks for settings, eg:

  settings:
    attributes:
      launch_mode:
        help_block: 'Rocket launch mode'

Validations

To validation work is required the default settings in the proper format, eg:

class Settings < RailsSettings::CachedSettings
  defaults[:company_name] = "Company name"
  defaults[:head_name] = "Head name"
  defaults[:manager_premium] = 19
  defaults[:show_contract_fields] = true
  defaults[:launch_mode] = [:auto, :manual]
end

Views

Rails.application.config.to_prepare do
  # Use admin layout:
  RailsSettingsUi::ApplicationController.module_eval do
    layout 'admin'
  end
  # If you are using a custom layout, you will want to make app routes available to rails-setting-ui:
  RailsSettingsUi.inline_main_app_routes!
end

Authentication & authorization

You can specify the parent controller for settings controller, and it will inherit all before filters. Note that this must be placed before any other references to rails-setting-ui application controller in the initializer:

RailsSettingsUi.parent_controller = 'Admin::ApplicationController' # default: '::ApplicationController'

Alternatively, to have custom rules just for rails-setting-ui you can:

Rails.application.config.to_prepare do
  RailsSettingsUi::ApplicationController.module_eval do
    before_filter :check_settings_permissions
  
    private
    def check_settings_permissions
       render status: 403 unless current_user && can_manage_settings?(current_user)
    end
  end
end
