Create Ruby on Rails views (only) after controllers and models are already created

I've obtained a project that have controllers (minimal code only) and models, but the views are missing. Is there a way to generate the views only using scaffold or another tool?

rails g scaffold User --migration=false --skip

The --skip means to skip files that already exist. (The opposite is --force.)

If you don't want helpers, --helpers=false.

Sample output after deleting my User views:

      invoke  active_record
   identical    app/models/user.rb
      invoke    test_unit
   identical      test/unit/user_test.rb
        skip      test/fixtures/users.yml
       route  resources :users
      invoke  scaffold_controller
   identical    app/controllers/users_controller.rb
      invoke    erb
       exist      app/views/users
      create      app/views/users/index.html.erb
      create      app/views/users/edit.html.erb
      create      app/views/users/show.html.erb
      create      app/views/users/new.html.erb
      create      app/views/users/_form.html.erb
      invoke    test_unit
   identical      test/functional/users_controller_test.rb
      invoke    helper
   identical      app/helpers/users_helper.rb
      invoke      test_unit
   identical        test/unit/helpers/users_helper_test.rb
      invoke  assets
      invoke    coffee
   identical      app/assets/javascripts/users.js.coffee
      invoke    scss
   identical      app/assets/stylesheets/users.css.scss
      invoke  scss
   identical    app/assets/stylesheets/scaffolds.css.scss

This is what the scaffold generator calls internally:

rails g erb:scaffold User

erb is the templating engine used, so you can also use haml:scaffold.

You must explicitly specify the fields you would like the scaffolding to use--rails does not automatically deduce them from the created model. For example:

rails g erb:scaffold User firstname lastname reputation

See rails g --help for options like skipping, forcing overwriting, and dry runs or generate scaffold --help for information specific to generating scaffolding.

I just encounter the same your problem. I did it. More detail is below:
- First I rename views/your_model folder to views/your_model_bak. In order to revert if fail later
- Then, execute command

rails g scaffold YourModel [field[:type][:index]] --skip

• Don't forget --skip option, it will not create exist files (controller and model in this case and few other files)
• Make sure list [field[:type][:index]] is up to date

-- Finally, you should update your permit in your_model controller.

Hope it can help you.

"Another tool"...

How about being able to do "script/generate view_for model_name"? :)

There is a gem for that - View Mapper. It has Ruby on Rails 2 and 3 versions.

One small tip is to add "--no-test-framework" if using Rspec and don't want test files generated for each view in spec/views
