Ruby on Rails 4.0.13

Since v3.0.20

Available in: v3.0.20 v3.1.12 v3.2.22.5 v4.0.13 v4.1.16 v4.2.9 v5.2.8.1 v6.0.6 v6.1.7.10 v7.0.10 v7.1.6 v7.2.3 v8.0.4 v8.1.2

Compare with:

resource(*resources, &block)

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 :geocoder

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

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

Options

Takes same options as resources.

Parameters

resources rest
block block
