Method deprecated or moved

This method is deprecated or moved on the latest stable version. The last existing version (v6.0.0) is shown here.

These similar methods exist in v7.1.3.2:

ActionDispatch::Routing::Mapper::Mapping::Scoping::Resources#resource

resource(*resources, &block) public

Sometimes, you have a resource that clients always look up without referencing an ID. A common example, /profile always shows the profile of the currently logged in user. In this case, you can use a singular resource to map /profile (rather than /profile/:id) to the show action:

resource :profile

This creates six different routes in your application, all mapping to the Profiles controller (note that the controller is named after the plural):

GET       /profile/new
GET       /profile
GET       /profile/edit
PATCH/PUT /profile
DELETE    /profile
POST      /profile
