Is there a way to generate the views separately using the rails generate command? I would also be willing to install a gem to accomplish that task f one exists. Basically the scaffolding command gives me too much and I would rather code my controller by hand. However, writing the index view with a table for the records would not be very efficient.

A Rails View is an ERb program that shares data with controllers through mutually accessible variables. If you look in the app/views directory of the library application, you will see one subdirectory for each of the controllers, we have created: book.
To generate a fully working scaffold for a new object, including model, controller, views, assets, and tests, use the rails g scaffold command. Then you can run rake db:migrate to set up the database table. Then you can visit http://localhost:3000/widgets and you'll see a fully functional CRUD scaffold.
To generate a controller and optionally its actions, do the following: Press Ctrl twice and start typing rails g controller. Select rails g controller and press Enter . In the invoked Add New Controller dialog, specify the controller name.
Ruby's and Ruby on Rails' Overall Popularity Although way behind main contenders, such as PHP or Python, Ruby still makes the cut for the 20 most popular programming languages list in 2022. The 2022 edition of Stack Overflow Annual Developer Survey also places RoR in a similar spot.
You can generate the controller and the view using the controller generator.
rails g controller controllername new create
This will create actions new and create with their corresponding views.
You still need to set up your routes manually with this.

One particular situation is when you want to add a new view to an existing controller.
In that case, just use the regular command, but be careful to say 'n' every time prompted in order to not overwrite existing files.
For example, adding a view called 'invite' to an existing controller named 'projects':
smith@ubuntuSrv16DEV4:~/railsapps/project_manager$ rails -v

smith@ubuntuSrv16DEV4:~/railsapps/project_manager$ rails generate controller projects invite

the first part is the name of the model/controller, the second part are the actions.
