Software Engineering Resources

A collection of resources, cheatsheets and code snippets I found helpful (or kept forgetting) during my Flatiron Software Engineering bootcamp.

HEY FRIENDS! This repo/resource is a perpetual work in progress. I'm not sure how big I want to expand it, but had a thought to include some resources I am gathering for my own knowledge. I'm open to suggestions or contributions.

Seed Data

1. Within the db folder, create a file named seeds.rb.
2. Create object instances. For example: Dog.create(:name => "Fido", :breed => "mutt"). Using create as opposed to new creates the Ruby object and saves it to the database
3. Run rake db:seed
