Congratulations! You're submitting your assignment.

Comprehension Questions

Question	Response
What is accomplished with raise ArgumentError?	It stops the program and raises an Error when you receive an invalid input.
Why do you think we made the .all & .find methods class methods? Why not instance methods?	because they are related to the class in general and we used them to get information from the class. Instance methods are used when we need specific information about objects or instances.
Think about the relation between Order and Customer. Is this relation one-to-one, one-to-many, or something else? How does that compare to the Solar System project?	Customer was like planet and order was like solar system. Order has a one-to-many relation with customer.
How is the relation between Order and Customer tracked in the CSV file? How is it tracked in your program? Why might these be different?	In customer, you can find the specific information about each customer. In order you can find the description of each order, the description includes the id of the customer. In Oder we used Customer.find to get the customer information and create a new order.
Did the presence of automated tests change the way you thought about the problem? How?	Yes, in Wave 1, I used my own names and I got errors and then I realized that I needed to change some of the names because they were related. I learned that is important to review the test first before writing your program because some times you don't think in all the possible situations.

I realized that I didn't do the tests for the wave 2. I added the tests.

What We're Looking For

Feature	Feedback
Baseline
Answered comprehension questions	Yes
Used Git Regularly	I would expect to see more commits on a project of this size.
Wave 1
All provided tests pass	yes
Using the appropriate attr_ for instance variables	mostly, see comment
Wave 2
All stubbed tests are implemented fully and pass	yes
Used CSV library only in .all (not in .find)	yes
Appropriately parses the product data from CSV file in Order.all	yes
Order.all calls Customer.find to set up the composition relation	yes
Additional Notes	Solid work. Check my comments to see what can be improved, and make sure that you don't leave in puts statements in the future!

[dHelmgren]

It's worth thinking about how you would solve this problem if you couldn't edit the csv to have headers.

[dHelmgren]

You need to take out puts statements before you submit! This is debugging code.

do all of these need to be accessors?
