DynMeta

Automate the lookup of page meta information based on the current request context. Meta information such as page titles and descriptions can be stored in a translations file rather than floating around in controllers or views.

Usage

Add DynMeta::Helper to your app:

# application_controller.rb
helper DynMeta::Helper

Set up your translations as follows:

en:
  meta:
    <meta key pluralized>:
      <controller>:
        <action>:
          <id>: "Some meta value"

For example:

en:
  meta:
    titles:
      users:
        new: "Create Your Account"
        edit: "Update Your Account"

You usually won't go down to the id level but occasionally it's useful:

en:
  meta:
    titles:
      pages:
        show:
          tos: "Terms of Service"
          pp: "Privacy Policy"
          about: "About My Site"

You can define catch-alls via the default key:

en:
  meta:
    titles:
      default: "My Super Site"
      users:
        default: "Manage Your Account"
        new: "Create Your Account"
        edit: "Update Your Account"

DynMeta provides one method meta. It's both a setter and a getter. Just use the meta method in your template:

<title><%= meta(:title) %></title>
<meta name="description" content="<%= meta(:description) %>" />

If you'd like to override meta content you can just pass a value to the meta method:

def show
  @user = User.find(params[:id])
  meta(:title, "#{@user.display_name} :: Profile")
end

You can also provide interpolations via the meta method rather than overriding entire locales:

def show
  @user = User.find(params[:id])
  meta(:title, :name => @user.display_name})
end
