This is boilerplate code for a has-many-through relationship. Make sure you fork the file to your repo!
You can define your models in the three files in folder app/models and then, test your code in the tools/console.rb file.
To run your code, type ruby tools/console.rb from the root directory in your terminal.
Here are some potential models you might use (The order of the models are random):
- Doctor, Patient, Appointment
- Artist, Genre, Song
- Recipe, Ingredient, Quantity
- Classroom, Student, Teacher
- Subscription, Magazine, Person
- Club, Student, Membership
When creating the models, be sure to include rich instance variables, so you can do more with the models! For instance, a doctor model might have things like name, field (field of study), and cost while a patient model might have things like name, ailments and income. In doing this, you might want to write methods where a patient can find the doctors (s)he can afford and/or a doctor appropriate for his/her pain.
There are no restrictions and no tests, so it's up to you to decide how to implement this!
