Middleman > Localization


    Middleman fully supports localization, and our middleman-dato plugin is 100% integrated with its conventions.

    First of all, in your config.rb file you need to activate the :i18 plugin, passing the array of languages you intend to offer to your visitors (most likely, they will be the same you configured in your DatoCMS administrative area):

    # config.rb
    activate :dato, token: 'YOUR_READ_ONLY_TOKEN'
    activate :i18n, langs: [:en, :it]

    The important thing to understand is that, when you have some localized fields in one of your models, DatoCMS records will return the value of the field for the current I18n.locale:

    I18n.with_locale(:en) do
    dato.blog_posts.first.title # => "Hello world!"
    I18n.with_locale(:it) do
    dato.blog_posts.first.title # => "Ciao mondo!"

    To generate multi-language pages with Middleman and DatoCMS, you have multiple choices.

    Create a localizable template

    Templates that live within the source/localizable directory will output one page per locale, and will have the I18n.locale already setup for you.

    As an example, suppose we have a single-instance model called home_page, with two localized single-line string fields: title and catch_phrase. We can create a multi-language homepage with the following template:

    <!-- source/localizable/index.html.erb -->
    <h1><%= dato.homepage.title %></h1>
    <p><%= dato.homepage.catch_phrase %></p>

    This will output two pages:

    • /index.html with the english content;

    • /it/index.html with the italian content.

    Create multi-language pages with proxies

    If you have a DatoCMS collection (ie. Articles) and you need to generate a multi-language detail page for each of its records, then you can use proxies:

    # config.rb
    activate :dato, token: 'YOUR_READ_ONLY_TOKEN'
    activate :i18n, langs: [:en, :it]
    dato.tap do |dato|
    # iterate over all the administrative area languages
    dato.available_locales.each do |locale|
    # switch to the nth locale
    I18n.with_locale(locale) do
    # iterate over the "Article" records...
    dato.articles.each do |article|
    # ...and create a proxy file for each article
    locals: { article: article },
    locale: locale
    ignore "templates/article.html.erb"

    The source/templates/article.html.erb template will be something along these lines:

    # source/templates/article.html.erb
    <h1><%= article.title %></h1>
    <div><%= article.content %></div>
