Run Rake Tasks

Execute Rake tasks with intelligent discovery and contextual help.

Arguments

The user may provide:

• No argument: List available tasks
• Task name: Run specific task (e.g., db:migrate)
• Pattern: Find matching tasks (e.g., db:*)
• Task with args: Run with arguments (e.g., greet[Alice])

Execution Strategy

List Available Tasks

# All tasks with descriptions
bundle exec rake -T

# All tasks (including those without descriptions)
bundle exec rake -AT

# Filter by pattern
bundle exec rake -T db
bundle exec rake -T test

Run a Task

bundle exec rake task_name

# With arguments
bundle exec rake "greet[Alice,Bob]"

# Multiple tasks
bundle exec rake db:migrate db:seed

# With environment
RAILS_ENV=production bundle exec rake db:migrate

Trace Execution

# Show task dependencies and execution order
bundle exec rake task_name --trace

# Dry run (show what would be executed)
bundle exec rake task_name --dry-run

Prerequisites

# Show task prerequisites
bundle exec rake -P task_name

Common Tasks

Database Tasks

# Generic database tasks (example structure)
bundle exec rake db:create
bundle exec rake db:migrate
bundle exec rake db:seed

# Note: These are examples. Actual task names depend on your Rakefile.

Testing

bundle exec rake test
bundle exec rake test:models
bundle exec rake spec            # RSpec (if configured)

Custom Tasks

Show how to find custom tasks in the project:

# List files defining tasks
ls lib/tasks/*.rake

Output Handling

• Use --trace when debugging task failures
• Show task descriptions when listing
• Suggest related tasks when a task fails

Examples

/ruby:rake                        # List all tasks
/ruby:rake -T db                  # List database tasks
/ruby:rake db:migrate             # Run migration
/ruby:rake "import[data.csv]"     # Run with argument
/ruby:rake --trace test           # Debug test task
