Showing Examples #

Description #

Using GitHub Copilot, developers can generate code based on provided examples. This can be incredibly useful when you expect the code that produces a specific output. In this pattern, we’ll explore how to create a Ruby on Rails model from a given example, such as generating JSON.

Example #

The following sample illustrates how you can provide an example in comments and ask GitHub Copilot to generate Ruby on Rails code to create the corresponding model.

# Example of code generation to create the following JSON:
# {
#   "name": "John Smith",
#   "age": 30,
#   "description": "This is a sample description.",
#   "country": "Japan",
#   "title": "Customer Success Architect",
#   "email": "johnsmith@example.com"
# }
rails g model users name:string age:integer description:text country:string title:string email:string

Exercise #

• Exercise 1: Based on the following example, generate the Ruby on Rails code to create a model for books.

  {
    "title": "Book",
    "author": "Jane Doe",
    "price": 19.99
  }
  

• Exercise 2: Experiment with different attributes and types in the JSON example, then generate the corresponding Rails code.
• Exercise 3: Test the generated code in a Rails project to ensure that it creates the expected model.

Checklist for Further Learning #

• Does the generated code accurately reflect the given example, creating the appropriate Ruby on Rails code?
• What were the key considerations or challenges when generating code from the provided example?
• How can you further customize or optimize the generated code to suit specific project requirements?
