I'm trying to solve a problem for a client.
It's a language school.
They have, courses so I have a Courses model and table.
Each course has a name and a description and a price_per_week field (a base price if you like).All is fine, or should I say, was fine.The client now wants to charge different prices depending on the length of the students course.
e.g.
1-2 weeks - price_per_week * 1.0 3-4 weeks - price_per_week * 0.9 5-6 weeks - price_per_week * 0.8 7-8 weeks - price_per_week * 0.7 8 weeks+ - price_per_week * 0.6
