Overview

Template configuration

Configuration DSL for the page templates. Can be accessed through PagesCore::Templates.configure.

PagesCore::Templates.configure do |config|
  # Configuration goes here
end

Configuring templates

Defaults for all templates can be configured with:

config.default do |default|
  default.enabled_blocks %i[name headline body]
  default.files :disabled
end

Individual template configurations override the defaults.

config.template(:article, :article_alt) do |t|
  t.enabled_blocks %i[name headline excerpt body boxout]
  t.files :enabled
end

Options

blocks

Yields the block configuration.

enabled_blocks

List of enabled blocks. Default: %i[headline excerpt body]

template

Template for all pages, unless overridden with sub_template. It will attempt to guess based on the parent page if set to :autodetect, which is the default value. Pass the :root option to set template at root level.

image

Enable images. Default: :enabled

files

Enable file uploads. Default: :disabled

tags

Enable tags. Default: :disabled

dates

Enable dates. Default: :disabled

sub_template

Children of the page will automatically have this template if configured. Defaults to nil, which fall back to the behaviour of template.

Block configuration

Blocks can be configured at top level, or per template:

config.default do |default|
  default.blocks do |block|
    block.byline("Byline", size: :field)
    block.embed("Video embed", size: :small, description: "Embed code")
  end
  default.enabled_blocks %i[headline byline body embed]
end

Valid sizes for text blocks are :field (single line), :small and :large.

Select blocks

Blocks can also be selects:

block.foobar("Foobar", type: :select, options: %w[Foo Bar Baz])

Pass a hash for multiple localizations:

block.foobar("Foobar", type: :select,
             options: { en: %w[Foo Bar Baz],
                        nb: %w[Fuu Baer Baez] })

Options can be set at runtime using a Proc:

block.foobar("Foobar", type: :select,
             options: -> { FooBar.template_options })
