stealth_dom_id extends Rails' dom_id helper by allowing you to generate DOM IDs using any attribute instead of the default database primary keys. This helps keep your internal database IDs private.

Add the gem to your application's Gemfile by running:

bundle add stealth_dom_id

Instead of exposing database IDs in your HTML elements with the standard dom_id helper:

<%= dom_id(@user) %>
# => "user_1"

You can use any available attribute of your choice:

<%= dom_id(@user, attribute: :public_id) %>
# => "user_a1b2c3"

The attribute parameter is optional and defaults to the model's primary key. Just like Rails' built-in dom_id, you can also include a prefix:

<%= dom_id(@user, :admin, attribute: :public_id) %>
# => "admin_user_a1b2c3"

You can set a default attribute to be used across your application. Add this to an initializer (e.g., config/initializers/stealth_dom_id.rb):

StealthDomId.configure do |config|
  config.default_attribute = :public_id
end

Now public_id will be used whenever no specific attribute is provided.

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install.
