I have a class:
class Foo
def self.test
@test
end
def foo
@test = 1
bar
end
private
def bar
@test = 2
end
end
object = Foo.new.foo
Foo.test
# => nil
The only way I could get it to output '2' is by making @test a class variable. Is there any other way around using the instance variable and being able to display it with Foo.test?
It's not really clear to me what you want to achieve, and why. Here's an example with a "class instance variable". It might be what you're looking for:
class Foo
class << self
attr_accessor :test
end
attr_accessor :test
def foo
@test = 1
bar
end
private
def bar
Foo.test = 2
end
end
foo = Foo.new
foo.foo
p foo.test
#=> 1
p Foo.test
#=> 2
