For this assignment, we'll be working with a restaurant review domain.

We have three models: Restaurant, Review, and Customer.

For our purposes, a Restaurant has many Reviews, a Customer has many Reviews, and a Review belongs to a Restaurant and to a Customer.

Restaurant - Customer is a many to many relationship.

Note: You should draw your domain on paper or on a whiteboard before you start coding. Remember to identify a single source of truth for your data.

Build out all of the functionality listed in the deliverables. The deliverables are listed in a suggested order, but you can feel free to tackle the ones you think are easiest. Be careful: some of the later deliverables may rely on earlier ones.

We've provided you with a tool that you can use to test your code. To use it, run python debug.py from the command line. This will start a ipdb session with your classes defined. You can test out the methods that you write here.

Writing error-free code is more important than completing all of the deliverables listed - prioritize writing methods that work over writing more methods that don't work. You should test your code in the console as you write.

Similarly, messy code that works is better than clean code that doesn't. First, prioritize getting things working. Then, if there is time at the end, refactor your code to adhere to best practices.

Before you submit! Save and run your code to verify that it works as you expect. If you have any methods that are not working yet, feel free to leave comments describing your progress.

Write the following functionality for the classes in the files provided. Feel free to build out any helper methods if needed.

• A Review belongs to a Restaurant, and a Review also belongs to an Customer.

• The reviews table should also have:

  • A star_rating column that stores an integer.

After creating the reviews table using a migration, use the seed.py file to create instances of your Review class so you can test your code.

**Once you've set up your reviews **, work on building out the following deliverables.

• Review customer
  • should return the Customer instance for this review
• Review restaurant
  • should return the Restaurant instance for this review

• Restaurant name
  • has a name that returns a string
• Restaurant price
  • has a price that returns an integer
• Restaurant reviews
  • returns a collection of all the reviews for the Restaurant
• Restaurant customers
  • returns a collection of all the customers who reviewed the Restaurant

• Customer first_name
  • has a first_name that returns a string
• Customer last_name
  • has a last_name that returns a string
• Customer reviews
  • should return a collection of all the reviews that the Customer has left
• Customer restaurants
  • should return a collection of all the restaurants that the Customer has reviewed

Use python debug.py and check that these methods work before proceeding.

• Customer full_name
  • returns the full name of the customer, with the first name and the last name concatenated, Western style.
• Customer favorite_restaurant
  • returns the restaurant instance that has the highest star rating from this customer
• Customer add_review(restaurant, rating)
  • takes a restaurant (an instance of the Restaurant class) and a rating creates a new review for the restaurant
• Customer delete_reviews(restaurant)
  • takes a restaurant (an instance of the Restaurant class) and removes all their reviews for this restaurant
  • you will have to delete entries from the reviews to get this to work!

• Review full_review
  • should return a string formatted as follows:

Review for {insert restaurant name} by {insert customer's full name}: {insert review star_rating} stars.

• Restaurant all_reviews
  • should return an list of strings with all the reviews for this restaurant formatted as follows:

[
  "Review for {insert restaurant name} by {insert customer's full name}: {insert review star_rating} stars.",
  "Review for {insert restaurant name} by {insert customer's full name}: {insert review star_rating} stars.",
]
