Rails Scaffold - Shell-Bash

Introduction

Rails Scaffold is a command-line tool that generates the boilerplate code for a CRUD (Create, Read, Update, Delete) application in Rails. It is a quick and easy way to get started with Rails development without having to write all of the standard code yourself.

The scaffold generator creates all the necessary files for a model including the migration, model, controller, views, and tests. You can also specify the attributes for your model and it will generate the appropriate input fields in the views.

Usage

To generate a scaffold for a model called "Product" with attributes "name", "description", and "price", run the following command in your terminal:

rails generate scaffold Product name:string description:text price:float

This will generate the following files:

• db/migrate/YYYYMMDDHHMMSS_create_products.rb
• app/models/product.rb
• app/controllers/products_controller.rb
• app/views/products/index.html.erb
• app/views/products/edit.html.erb
• app/views/products/show.html.erb
• app/views/products/new.html.erb
• test/controllers/products_controller_test.rb
• test/fixtures/products.yml
• test/models/product_test.rb

Options

Rails Scaffold also provides several options to customize the generated code:

• --no-migration - Skips generating a migration file
• --no-controller - Skips generating a controller file
• --no-assets - Skips generating assets files (javascript and css)
• --no-helper - Skips generating a helper file
• --no-test-framework - Skips generating test files
• --no-scaffold-stylesheet - Skips generating a scaffold stylesheet (app/assets/stylesheets/scaffolds.css.scss)

You can also generate a scaffolding for a nested resource by specifying the parent resource:

rails generate scaffold Comment content:text post:references

This will generate the following files:

• db/migrate/YYYYMMDDHHMMSS_create_comments.rb
• app/models/comment.rb
• app/controllers/comments_controller.rb
• app/views/comments/index.html.erb
• app/views/comments/edit.html.erb
• app/views/comments/show.html.erb
• app/views/comments/new.html.erb
• test/controllers/comments_controller_test.rb
• test/fixtures/comments.yml
• test/models/comment_test.rb

Conclusion

In conclusion, Rails Scaffold is a very useful tool for generating boilerplate code for Rails applications. It saves time and effort, and helps developers get started quickly and easily. With its many customization options, it allows developers to easily tailor the generated code to their needs.
