Installing a Front-End Framework

Refer to instructions for:

In summary, to install a front-end framework, add the gems you need. Then use the RailsLayout gem. It will set up your assets files.

Add the gems you need to your Rails application Gemfile:

Zurb Foundation 5.0


gem 'foundation-rails'

Note: Check the status of these issues before using Foundation 5.0:

Zurb Foundation 4.0


gem 'compass-rails'
gem 'zurb-foundation'

Bootstrap 3.0


gem 'bootstrap-sass'

Bootstrap 2.3


gem 'bootstrap-sass', '~> 2.3.2.2'

Use Bundler

Use Bundler to install the gem:


$ bundle install

Install the RailsLayout Gem

Add it to your Rails application Gemfile:


group :development do
  gem 'rails_layout'
end

You don’t need the gem deployed to production, so put it in the development group.

If you want to use a newer unreleased version from GitHub:


group :development do
  gem 'rails_layout', github: 'RailsApps/rails_layout'
end

Use Bundler to install the gem:


$ bundle install

The “layout:install” Command

The command will rename application.css to application.css.scss.

It will add:

  • framework_and_overrides.css.scss

And modify the JavaScript asset file:

  • application.js

It will set up a default application layout.

It creates partials for:

  • Rails flash messages
  • navigation links

Supported Frameworks

You can generate layout files suitable for use with the following front-end frameworks:

  • foundation5 – Zurb Foundation 5.0
  • foundation4 – Zurb Foundation 4.0
  • bootstrap3 – Bootstrap 3.0
  • bootstrap2 – Bootstrap 2.3
  • simple – simple layout
  • none – removes all changes

Generated Files

The RailsLayout gem generates application layout files:

  • app/views/layouts/application.html.erb
  • app/views/layouts/_messages.html.erb
  • app/views/layouts/_navigation.html.erb
  • app/views/layouts/_navigation_links.html.erb

Additionally, when the simple option is selected:

  • app/assets/stylesheets/simple.css

Note About the Navigation Partials

Two navigation partials are created:

  • app/views/layouts/_navigation_links.html.erb
  • app/views/layouts/_navigation.html.erb

The first file contains no framework-specific styling. It is only a list of links. You can add additional links to this file as needed.

The second file contains framework-specific styling.

Support for ERB, Haml, or Slim

If you are using ERB for Rails views, the RailsLayout gem will generate ERB files.

If you are using Haml or Slim, the RailsLayout gem will generate Haml or Slim files instead.

Additional Documentation

See these articles for information about how to set up the application layout:

Look at the Learn Rails example application to see how the generated files from the RailsLayout gem are used. You’ll find details about the example application in the book Learn Ruby on Rails.

Zurb Foundation 5.0 Layout

To create layout files for use with Zurb Foundation 5.0:


$ rails generate layout:install foundation5

Use --force if you want to overwrite existing files:


$ rails generate layout:install foundation5 --force

See the files that are generated:

The RailsLayout gem will create the file:

and modify the file:

Zurb Foundation 4.0 Layout

To create layout files for use with Zurb Foundation 4.0:


$ rails generate layout:install foundation4

Use --force if you want to overwrite existing files:


$ rails generate layout:install foundation4 --force

See the files that are generated:

The RailsLayout gem will create the file:

and modify the file:

Bootstrap 3.0 Layout

To create layout files for use with Bootstrap 3.0:


$ rails generate layout:install bootstrap3

Use --force if you want to overwrite existing files:


$ rails generate layout:install bootstrap3 --force

See the files that are generated:

The RailsLayout gem will create the file:

and modify the file:

Bootstrap 2.3 Layout

Generate a Simple Layout

To create a set of simple layout files:


$ rails generate layout:install simple

Use --force if you want to overwrite existing files:


$ rails generate layout:install simple --force

See the files that are generated:

The RailsLayout gem will create the file:

Reverting to None

To revert your application to a default application layout:


$ rails generate layout:install none

The RailsLayout gem will remove any files it may have added:

  • app/views/layouts/_messages.html.erb
  • app/views/layouts/_navigation.html.erb
  • app/assets/stylesheets/simple.css
  • app/assets/stylesheets/bootstrap_and_overrides.css.scss
  • app/assets/stylesheets/foundation_and_overrides.css.scss
  • app/assets/stylesheets/framework_and_overrides.css.scss

Additionally, it will restore these files to the default versions:

  • app/views/layouts/application.html.erb
  • app/assets/javascripts/application.js

The file app/assets/stylesheets/application.css.scss will contain a CSS rule but you can ignore it or remove it.

The “layout:navigation” Command

If you are using Devise for authentication, you can generate a navigation links partial containing links for Devise.

This command is used to populate the navigation bar in starter applications created by the Rails Composer tool.


$ rails generate layout:navigation --force

This creates a file app/views/layouts/_navigation_links.html.erb:


<%# add navigation links to this file %>
<li><%= link_to 'Home', root_path %></li>
<li><%= link_to 'About', page_path('about') %></li>
<li><%= link_to 'Contact', new_contact_path %></li>
<% if user_signed_in? %>
  <li><%= link_to 'Logout', destroy_user_session_path, :method=>'delete' %></li>
<% else %>
  <li><%= link_to 'Login', new_user_session_path %></li>
<% end %>
<% if user_signed_in? %>
  <li><%= link_to 'Edit account', edit_user_registration_path %></li>
<% else %>
  <li><%= link_to 'Sign up', new_user_registration_path %></li>
<% end %>
<% if user_signed_in? %>
  <% if current_user.has_role? :admin %>
    <li><%= link_to 'Admin', users_path %></li>
  <% end %>
<% end %>

The full set of links will be created if the following files are found in your application:

  • app/views/devise/sessions/new.html.erb
  • app/views/devise/registrations/new.html.erb
  • app/views/users/index.html.erb

The “layout:devise” Command

Devise is a gem for authentication and user management (signup, login, and related features). Devise provides a utility command rails generate devise:views. The Devise command creates view files for signup, login, and related features. However, the views generated by Devise lack CSS styling.

Use the RailsLayout gem to generate Devise views with styling for Bootstrap or Foundation.

  • $ rails generate layout:devise foundation5
  • $ rails generate layout:devise bootstrap3

The command will create (or replace) these files:

  • app/views/devise/sessions/new.html.erb
  • (TODO: more to come)

Additionally, the command will append Sass mixins to accommodate Bootstrap or Foundation to the file:

  • app/assets/stylesheets/framework_and_overrides.css.scss

The Sass mixins allow any view to be used with either Bootstrap or Foundation (so we don’t have to maintain separate views for each front-end framework).

Limitations

At this time, with the “layout:devise” command, only Foundation 5 or Bootstrap 3 are supported. Files are not generated for Haml or Slim.
