Instance methods can be added to classes by plugins using add_to_class, defined as:

def add_to_class(class_name, attr, &block)
  reloadable_patch do |plugin|
    klass = class_name.to_s.classify.constantize rescue class_name.to_s.constantize
    hidden_method_name = :"#{attr}_without_enable_check"
    klass.public_send(:define_method, hidden_method_name, &block)

    klass.public_send(:define_method, attr) do |*args|
      public_send(hidden_method_name, *args) if plugin.enabled?
    end
  end
end

Is there an existing way to do something like this, where the defined method takes arguments?

add_to_class(Guardian, :ensure_user_can_access_report, group, report) do
  ...
end

This seems like what you’re looking for. Makes for a good example.

So, basically, you’ll have to make those params as params to the lambda itself.

Yeah, thats exactly it. Thanks!

You can do the same thing the ruby way too.
