Determine which value was selected

I have three numerical variables: on_the_ground, double_round_trip and point_to_point. The price function returns one of these based on some simple logic.
Below is how it currently works.
def price
return on_the_ground if date_range == 1
values = [
on_the_ground,
double_round_trip
]
if !turbo? && !vlj?
values.push(point_to_point)
end
values.compact.min
end
I'd like to have a function that can return a symbol based on which value should be returned. For example:
def price_name
return :on_the_ground if date_range == 1
... etc...
end
ruby algorithm logic

A method can return aSymbol, just like theprice_namemethod above does. What exactly is the issue?

To do that you need a mapping between values and names. UseHashto do that.

If I get your point, why not use an array?
def price_name_for date_range
[:on_the_ground, :double_round_trip, :point_to_point][date_range-1]
end
price_name_for 1 #=> :on_the_ground
price_name_for 2 #=> :double_round_trip
price_name_for 3 #=> :point_to_point

It's a little more complicated than that. There are some conditions for the point to point price to be in the array. I've provided an answer below showing how I solved it.
