dynamic controller code

is it possible to dynamically create controller code??

for example if you have a parent element @parent and children element @parent.daughter and @parent.son.

@parent.daughter.class = daughter @parent.son.class = son

so if we wanted to add a dog to all of our sons or all of our daughters when a controller element is called we would have to do something like this.

def dog     if @child.class == son        for son in @parent.sons            son.dog = true            son.save!        end     else        for daughter in @parent.daughters            daughter.dog = true            daughter.save!        end     end end

Duplicating code like this is annoying and not very DRY is anything like this remotely possible instead ??

def dog     child_type = @child.class        for child_type in @parent.child_type+s            child_type.dog = true            child_type.save!        end end

this would cut code almost in half, for this situation. If there is anything capable of dynamically generating controller code based on object classes or even defined variables please let me know!!

Well you could write something like this:

def set_dog(association_name)   collection = @parent.send association_name   collection.each {|element| element.update_attributes :dog => true} end

Although I'd have this as method on the parent class, rather than in the controller.
