Overview

The general route of Wallaby::Engine looks like as follow:

/admin/order::items

Therefore, to override this route, dev needs to define a resources as below before mounting Wallaby::Engine:

namespace :admin do
  # NOTE: in order for the route to work properly,
  # the colon before words need to be escaped in the path option
  resources :items, path: 'order:\:item', module: :order
end
wallaby_mount at: '/admin'

So to find out if any route has been overriden with current request, e.g. ‘/admin/order::items/1/edit`, we will look into the following conditions:

  • begins with ‘/admin`

  • same action as the given action

  • default controller exists (as ResourcesRouter does not define static controller)

Then we use this route’s params and pass it to the origin ‘url_for`.
