Question 1

How do I use active_link_to with nested routes in Rails?

Accepted Answer

Use path helpers for nested routes and active options like :inclusive or regex. For example, for /users/1/posts, set active: /^\/users\/\d+\/posts/ or match controllers/actions like [['users'], ['show']] to handle dynamic segments.

Question 2

active_link_to vs manually adding active classes – which is better?

Accepted Answer

active_link_to is better for reducing boilerplate and handling complex logic automatically, while manual classes offer more control for simple, static navigation. Use active_link_to when you need flexibility with URLs, controllers, or params.

Question 3

How to customize CSS classes for active links in active_link_to?

Accepted Answer

Use the class_active and class_inactive parameters in the helper. For instance, active_link_to 'Home', root_path, class_active: 'current' will add 'current' class when the link is active, as shown in the README examples.

Question 4

Can active_link_to work with Turbo or Hotwire in Rails?

Accepted Answer

It can work, but may require adjustments since Turbo changes page loads without full refreshes. Ensure active detection considers Turbo visits or supplement with JavaScript for real-time updates, as the gem relies on server-side request data.

Question 5

How to handle active states for query parameters with active_link_to?

Accepted Answer

Use the active: hash option to match specific params. For example, active_link_to 'Admin', users_path(role: 'admin'), active: { role: 'admin' } marks the link active when the role param equals 'admin', as demonstrated in the README.

Question 6

active_link_to or other gems like simple-navigation for Rails?

Accepted Answer

active_link_to is lightweight and integrates directly with link_to, ideal for custom navigation. Gems like simple-navigation offer more features like menus and breadcrumbs but are heavier. Choose based on whether you need simple active states or full navigation suites.
