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?

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.

To generate views after controller and models are already created, you may use the command line. You switch to the folder in which you want to create the new view. For example:

$ cd name_app/app/views/controller_name
$ touch name_file

To go back of one directory use:

$ cd ..

"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.

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.

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

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
