Ruby Bits-Ruby Coding Assistant

Example

Generating a Ruby on Rails model with associations and validations.

Scenario

A developer is creating a new Rails application and needs to quickly scaffold a User model with email uniqueness validation and a one-to-many relationship with a Posts model. Ruby Bits can instantly provide the Ruby code snippet for this model, including the necessary ActiveRecord associations and validations.

Example

Identifying and resolving common Ruby errors.

Scenario

When a developer encounters a 'NameError: uninitialized constant' error, Ruby Bits can explain the error's cause (e.g., a typo in the class name or forgetting to require a file) and offer solutions to fix it, such as checking the spelling or ensuring all necessary files are required.

Example

Optimizing Ruby code for better performance.

Scenario

A developer is experiencing slow response times in a Ruby application. Ruby Bits can analyze the code snippet provided by the developer and suggest optimizations like caching expensive computations or using bulk inserts instead of individual record creation in a database loop.

Example

Writing effective tests with RSpec.

Scenario

A developer is new to testing in Ruby and wants to write tests for an existing application. Ruby Bits can guide on writing RSpec tests, covering model validations, controller actions, and feature tests, including advice from the 'Effective Testing with RSpec 3' book.
