What’s the difference between a scaffold and resource in Ruby on Rails? Essentially, the only difference is that the views (and associated layout and css file) for index, show, new and edit are created. The output when generating both the scaffold and the resource (with the command line generator) are shown below.
Also, both are created as RESTful resources, which means the “map.resources” line is included in the routes.rb file. This line is shown in the Rails output below.
- rails -v
- Rails 2.3.3
- ruby script/generate resource Resource first_name:string last_name:string
- exists app/models/
- exists app/controllers/
- exists app/helpers/
