Class Method Details

.admin_importmaps ⇒ Set<Hash>

Additional importmaps to be included in the Alchemy admin UI

Be sure to also pin modules with Alchemy.importmap.

Example

# config/alchemy/importmap.rb
Alchemy.importmap.pin "alchemy_solidus", to: "alchemy_solidus.js", preload: true
Alchemy.importmap.pin_all_from Alchemy::Solidus::Engine.root.join("app/javascript/alchemy_solidus"),
  under: "alchemy_solidus",
  preload: true

# lib/alchemy/solidus/engine.rb
initializer "alchemy_solidus.assets", before: "alchemy.importmap" do |app|
  Alchemy.admin_importmaps.add({
    importmap_path: root.join("config/importmap.rb"),
    source_paths: [
      root.join("app/javascript")
    ],
    name: "alchemy_solidus"
  })
  app.config.assets.precompile << "alchemy_solidus/manifest.js"
end

Returns:

  • (Set<Hash>)

end

.admin_js_imports ⇒ Object

Additional JS modules to be imported in the Alchemy admin UI

Be sure to also pin the modules with Alchemy.importmap.

Example

Alchemy.importmap.pin "flatpickr/de",
  to: "https://ga.jspm.io/npm:[email protected]/dist/l10n/de.js"

Alchemy.admin_js_imports << "flatpickr/de"

.link_dialog_tabs ⇒ Object

Configure tabs in the link dialog

With this configuration that tabs in the link dialog can be extended without overwriting or defacing the Admin Interface.

Example

# components/acme/link_tab.rb
module Acme
  class LinkTab < ::Alchemy::Admin::LinkDialog::BaseTab
    def title
      "Awesome Tab Title"
    end

    def name
      :unique_name
    end

    def fields
       [ title_input, target_select ]
    end
  end
end

# config/initializers/alchemy.rb

    Alchemy::Admin::LinkDialog::ExternalTab,
    Alchemy::Admin::LinkDialog::FileTab
  ])
end

.preview_sources ⇒ Object

Define page preview sources

A preview source is a Ruby class returning an URL that is used as source for the preview frame in the admin UI.

Example

# lib/acme/preview_source.rb
class Acme::PreviewSource < Alchemy::Admin::PreviewUrl
  def url_for(page)
    if page.site.name == "Next"
      "https://user:#{ENV['PREVIEW_HTTP_PASS']}@next.acme.com"
    else
      "https://www.acme.com"
    end
  end
end

# config/initializers/alchemy.rb
require "acme/preview_source"
Alchemy.preview_sources << Acme::PreviewSource

# File 'lib/alchemy.rb', line 42

def self.preview_sources=(sources)
  @_preview_sources = Array(sources)
end

.publish_targets ⇒ Object

Define page publish targets

A publish target is a ActiveJob that gets performed whenever a user clicks the publish page button.

Use this to trigger deployment hooks of external services in an asychronous way.

Example

# app/jobs/publish_job.rb
class PublishJob < ApplicationJob
  def perform(page)
    RestClient.post(ENV['BUILD_HOOK_URL'])
  end
end

# config/initializers/alchemy.rb

Alchemy::I18n.translate(:hello)

You can use this shortcut method:

Alchemy.t(:hello)
