Managing admin users

Currently, LINES does not offer a GUI for managing users, but you can use a rake task to do so:

rake lines:add_user

To update an existing user, you’ll need the rails console with ‘rails c’

UPDATE an existing user

u = User.find_by_email('[email protected]') = "[email protected]"
u.password = "newsekret"

Google Sitemap

The sitemap_generator gem ( handles the creation of site maps for search engines. To update the sitemap on server, run:

bundle exec rake sitemap:refresh:no_ping # don’t ping search engines
bundle exec rake sitemap:refresh         # ping search engines

Don’t forget to adjust the full URL to your sitemaps in public/robots.txt

Copy/update stylesheets

Run rails g lines:copy_styles to install stylesheets from newer gem versions. Keep in mind to backup your overrides and other customizations before doing so!


Find the SASS files inside the app/assets/stylesheets/lines/ directory.

Use the app/assets/stylesheets/lines/lines_overrides.scss file to adjust existing styles or add new ones.

Modify custom hero images

You can change, remove, or add the HERO_IMAGES variable inside the config/lines_config.yml file. The corresponding images reside inside the public/heroes directory.

Header (Meta) & Footer

To change the header/meta/footer elements you need to modify app/views/layouts/lines/application.html.erb and the corresponding partials.
