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

Question

I got a project that has controllers (only minimal code) and models, but no views. Is there a way to generate views only with a scaffold or other tool?

Answer 1

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

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

If you do not 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 

Answer 2

This is what the internal sounder generator calls inside:

 rails g erb:scaffold User 

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

You must explicitly specify the fields that you want to use to use the forests: rails does not automatically derive them from the created model. For example:

 rails g erb:scaffold User firstname lastname reputation 

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

Answer 3

"Another tool" ...

What about the possibility of " script/generate view_for model_name "? :)

There is a pearl for this - View Mapper . It has versions of Ruby on Rails 2 and 3.

Answer 4

I just run into the same problem. I have done it. More details below:
- First, I renamed the views / your_model folder to views / your_model_bak. To return if an error occurs later - Then run the command

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

• Do not forget that the -skip option will not create existing files (the controller and model in this case and several other files)
• Make sure the list [field [: type] [: index]] is updated

- Finally, you must update your permission in your_model controller.

Hope this helps you.

Answer 5

One little --no-test-framework advice is to add the --no-test-framework when using Rspec and you don’t want the test files generated for each view in spec / views

Answer 6

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

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

To return to a single directory, use:

 $ cd ..
