Metazilla

Simple gem to deal with titles and meta tags for Rails 3+.

Add this line to your application's Gemfile:

gem "metazilla", "~> 1.0"

And then execute:

$ bundle

title("My page") to set page title.

title to get page title.

app_title("My app") to set application title.

app_title to get application title.

full_title generates full title (page and app title joined).

title_tag generates <title> tag with full title. Place this in your layout.

If you want your title tag content to look like this: My Application > My cool page, tell Metazilla to use custom separator.

config/initializers/metazilla.rb:

Metazilla.configure do |config|
  config.separator = " > "
end

meta(:description, "My app description") to set meta tag.

meta(:description) to get meta tag.

meta_tag(:description) generates <meta> tag. Place this in your layout.

Metazilla fully supports Rails built-in i18n engine.

Place your titles and meta tags in the en.yml file:

en:
  app: My app
  meta:
    description: My app.
  posts:
    title: Posts
    index:
      title: Posts list
      meta:
        description: My posts list.

All defined instance variables passed to translations.

YAML:

en:
  titles:
    users:
      show: User: %{user}

Model:

class User < ActiveRecord::Base
  def to_s
    user.full_name
  end
end

Controller:

def show
  @user = User.find(params[:id])
end

View:

title # => User: John Doe

Metaziila uses name of the current action for resolving titles, so when you submit a form and it fails to save, your rendered new template inside the create action. To avoid setting duplicated titles for both new and create (and edit and update), this actions is mapped in gem's configuration. If your application have similar non-RESTful pair of actions, your can add them to mapping:

config/initializers/metazilla.rb:

Metazilla.configure do |config|
  config.mapping[:perform_parse] = :parse
end

Now you can define title only for parse action, perform_parse will use it automagically.

Namespaced controllers/views are supported, so you can have separate set of titles for different parts of your application.

en:
  app: My app
  admin:
    app: My admin panel
