Fix inertia routes helper

[skryukov]

This PR improves inertia routes helper by adding support for:

• namespaced and scoped routes

namespace :settings do
  inertia 'appearance' => 'settings/appearance'
end

scope :settings do
  inertia 'appearance' => 'settings/appearance'
end

• symbol notation for route paths

inertia settings: 'settings'

• shorthand syntax with default component:

inertia :settings # => pages/settings.jsx

namespace :settings do
  inertia :appearance # => pages/settings/appearance.jsx
end

Looks great, thank you! Just a quick question to make sure I understand the code.

[BrandonShar]

Now matter how much Ruby I write, I'm still regularly surprised by syntax 😄

[BrandonShar]

Can you explain what this is doing?

[skryukov]

This overrides defaults coming from the namespace helper. Btw, I missed the resource helper, will update the PR to support it as well.

[bknoles]

If I understand correctly, Rails will prepend module/namespace/resource paths onto route in get(route.... That information is stored in @scope. But we're already taking all that into account in extract_route_and_component. @scope.new(module: nil) just clears out the data that would prepend those paths, and the ensure block sets everything back for the next line in the routes file.

[skryukov]

Added a cleaner solution 😅

[bknoles]

super clean looking!

[skryukov]

This is a bit simplistic but I hope it's good enough:

resources :foo do
  resources :bar do
    inertia :baz # => pages/bar/baz.tsx
  end
end

[brodienguyen]

Did you mean foo instead of pages please?

resources :foo do
  resources :bar do
    inertia :baz # => foo/bar/baz.tsx
  end
end

[skryukov]

nope, pages/bar/baz.tsx mimics Rails routing: https://guides.rubyonrails.org/routing.html#nested-resources

This looks good to go to me! Here's how it looks in the routes file.

Brandon, do you still have questions or can we merge?
