Hi all,
I'm trying to setup some kind of dynamic method / accessor assignment to objects. But I don't want the other objects from the same class to know about "personal" methods. I'm just learning Ruby, so it could be I missed something.
For example:
class MyThing
def create_method(method)
# I found two things on internet which can acchieve this
# self.class.class_eval { attr_accessor method }
# AND
# self.class.send(:define_method, method, &block)
# but I'm not sure which is the best one to use, but I think
# I prefer the attr_accessor, because that's the functionality
# I need
end
end
# Create first object
a = MyThing.new
a.create_method('box') # Adds a method box to a
a.box = 'something inside'
# The nicest thing would be if I could do something like this:
a.create_method('box','some_value'), so a.box is populated with 'some value'
# Create second object
b = MyThing.new
# I don't want the following to happen
b.box = 'something other'
I don't want the method 'box' be available to b, only to a
How can I achieve this?
I saw it was possible to achieve this with something like this:
class YourThing < MyThing
# A placeholder class for the dynamic methods
end
but I don't know the name of the class on forehand, so if something like this is possible:
class #{i_want_this_class} < MyThing
# A placeholder class for the dynamic methods
end
That would be nice.
Sincerely,
Frodo Larik
