Lab

You are going to make a table for tracking bounties for Space Cowboys.

An entry in the bounty table must have a selection of 4 of these properties:

• name
• species
• bounty value
• danger level (low, medium, high, ermagerdyerderd)
• last known location
• homeworld
• favourite weapon
• cashed_in
• collected_by

Getting Started Checklist

1. Set up your directory structure
2. Create console.rb which will be used to create some new objects and practice your methods as required (use this as you are writing the class & methods to test them)
3. Create a Ruby file for your Bounty class
4. Write your class definition in the file - initialize, attr_readers, instance variables
5. Make the database - createdb in command line
6. Make a .sql file and write some SQL to create your database table
7. Run the .sql file to set up the table (psql -d data_base_name -f file_name.sql)
8. Implement save, update and delete methods on your class
9. Implement a find_by_name method that returns one instance of your class when a name is passed in, or nil if no instance is found. Note: this will probably be another class method ClassName.find_by_name(name) (do you have to use a map method if it's a single result?)
10. Implement a second find method that returns one instance of your class when an id is passed in.
