目前我有这个:
class Group < ActiveRecord::Base delegate :publish_group_creation, :to => 'MyAppModules::Publisher' after_create :publish_group_creation end
问题是Publisher.publish_group_creation
收到1个参数(即将发布的组)
我试过这样的事情;
delegate :publish_group_creation, :to => 'MyAppModules::Publisher', :group => self
但它不起作用,使用delegate
传递参数的正确方法是什么?

我不确定这是否适用于您的场景,但您可能会尝试重新处理一下。像
这样的东西module MyAppModules::Publisher
def publish_group_creation
...
end
end
class Group < ActiveRecord::Base
include MyAppModules::Publisher
after_create :publish_group_creation
end

通过回调调用的方法不会在Rails中接收参数。
试试这个:
class Group < ActiveRecord::Base
after_create :publish_group
private
def publish_group
MyAppModules::Publisher.publish_group_creation(self)
end
end
