Common Mistakes

Swapping controller and action names.

Using incorrect action names like 'index_action'.

Using a controller name that doesn't exist.

The root route should point to the controller and action in the format "controller#action". Here, "home#index" means the index action of the home controller.

Swapping controller and action names.

Using a non-existent controller or action.

The route should map to the 'show' action of the 'users' controller, so the correct format is "users#show".

💡 Hint

Common Mistakes

Using wrong controller or action in 'to:'.

Using incorrect or unrelated names in 'as:'.

The route maps to the 'new' action of the 'sessions' controller, and the route is named 'login' for easy reference.

💡 Hint

Common Mistakes

Mixing up the order of nested resources.

Using incorrect action names in 'only:'.

This defines nested routes where 'comments' are nested inside 'posts', and only the 'create' action is available for comments.
