Accessing a variable in the view

Now I’ve decided I want to access factor in my view…

but it’s blank when i try
Factor: <%= @course.factor %>

How do I do it?

here’s my model…


class Course < ActiveRecord::Base

has_one :enquiry

attr_accessor :duration_in_weeks
attr_reader :factor

def self.all_courses
find(:all)
end

def self.active_courses
# find(:all)
# find(:all, :conditions => [“active = ?”, true], :order =>
‘created_at DESC’, :limit => 5)
find(:all, :conditions => {:archive => false}, :order =>
‘display_order ASC’, :limit => 100)
end

def self.old_courses
# find(:all)
# find(:all, :conditions => [“active = ?”, true], :order =>
‘created_at DESC’, :limit => 5)
find(:all, :conditions => {:archive => true}, :order => ‘created_at
DESC’, :limit => 100)
end

def discounted_price
@factor = case @duration_in_weeks
when 1…4
1.0
when 5…12
0.9
when 13…24
0.8
when 25…47
0.7
else # from 48 and up
0.6
end

total_price * @factor

end

def total_price
(@duration_in_weeks * price_per_week) + registration_fee
end

def duration_in_weeks=(duration_in_weeks)
@duration_in_weeks = duration_in_weeks.to_i
end

end

Until the discounted_price method is called, @factor has no value.

You could pull the case statement that sets @factor into its own
method and call that ‘factor’. Then you can omit the attr_reader
(since you defined the method yourself) and @course.factor will do
what you originally expected.
