Only happens the first time:
class Interaction < ActiveInteraction::Base
boolean :a
def execute
a = false
a = a
end
end
p Interaction.run!(a: true)
# => false
from active_interaction.
Getting more confused:
class Interaction < ActiveInteraction::Base
boolean :a
def execute
b = a
a = b
end
end
p Interaction.run!(a: true)
# => true
from active_interaction.
Adding self.
makes it work:
class Interaction < ActiveInteraction::Base
boolean :a
def execute; a = self.a end
end
p Interaction.run!(a: true)
# => true
from active_interaction.
Turns out this is not a bug against ActiveInteraction — it's just weird Ruby behavior!
class Klass
def initialize; @thing = 'swamp' end
def thing; @thing end
def thing=(other) @thing = other end
def test1; thing = thing end
def test2; self.thing = thing end
def test3; thing = self.thing end
end
klass = Klass.new
p klass.test1 # => nil
p klass.test2 # => "swamp"
p klass.test3 # => "swamp"
