ticket = Ticket.new(“yer”,“11/12/2006”)

ticket.price = (5.00)
puts “ticket mooch is #{ticket.price}”
You define the price= method, but you don’t define the price method.
You can’t access to instance variables from outside the instance unless
you explicitly allow it via appropriate accessors. In your case,
replacing the price= definition by
attr_accessor :price
should work pretty well. You might want to use attr_reader to only grant
read acces to an instance variable or attr_writer to only grant write
access.
Sure, where you’ve got a method “price=(amount)”, below:
def price=(amount) @price = amount
end
this only handles the assigning of the price variable. This means that:
ticket.price = (5.00)
works fine, but trying to access ticket.price results in the error
you’re seeing (hence why the error doesn’t occur on the above line, but
on a later line). You simply need a method declaration for retrieving
the variable value within your class, so try putting this in there:
def price @price
end
This then ensures you’ve got one method (“price=”) that handles the
assignation of values, and one method (“price”) to retrieve the current
value.
