GOAL

Be able to push to Heroku as any of three Heroku users from a single computer and a single user.

For this, you will not be allowed to copy and paste anything - except SSH keys themselves, because we're not THAT evil.

If you get error messages, read them carefully, and make note of what you understand, what you don't understand, and what you think you understand.

# Great now comment out that line. We'll have a bunch of code examples you will have to uncomment to get them to run.
# Your editor has a short cut for commenting and uncommenting code so don't do this manually.
# Ok. Something specific to classes
# We mentioned some specific stuff about property 'visibility'. 
# All that means is what can you ask your object for that won't piss it off.

When we last left our application it there were list and task models. They were associated with a list having many tasks and a task belonging to a list.
We wanted to build a nested form so we had to let the list model know it has some additional responsibilities.

In the List model we had to add this:

  accepts_nested_attributes_for :tasks
This line creates an attribute on the list objects available at :task_attributes.

Since rails has mass assignment protection, and we WANT our form to use mass assignment to create tasks through a list we need to white list our new attribute on the attr_accessible line
  attr_accessible :name, :tasks_attributes
