access params in ActiveAdmin

I need to get access to params inside following block:

ActiveAdmin.register Discussion, namespace: :dev_panel do
  raise params.inspect
  ...
end

I need it exactly in there, not in controller or inside action_item whatsoever.

But I'am getting

undefined local variable or method params for ActiveAdmin::ResourceDSL

Does anyone know how do I do that?

EDIT

My goal is to be able to define such two blocks in admin/discussions.rb:

ActiveAdmin.register Discussion, namespace: :dev_panel do
  belongs_to :my_active_submission, parent_class: ClientApplication
  ...
end

and

ActiveAdmin.register Discussion, namespace: :dev_panel do
  belongs_to :lead_submission, parent_class: ClientApplication
  ...
end

The issue with that, is that AA only treats the latter block, and behaves as there is no previous one. My bet is that issue is with namespace - I can't define two blocks of same resource and namespace.

It is technical not possible to access params at that place. The register block is only executed one at the loading and not per request.

Write down a full example, like you have access to params and we maybe find a other solution.

Did you try defining your Discussion with as: option? I have a model which needs to be used in a number of different context so I set up:

ActiveAdmin.register Discussion, as: 'ActiveDiscussion' do; end
ActiveAdmin.register Discussion, as: 'PoliticalDiscussion' do; end

Or you can sub-class Discussion as you needed

class ActiveDiscussion < Discussion; end
class PoliticalDiscussion < Discussion; end

And then register them to ActiveAdmin.

ActiveAdmin.register ActiveDiscussion do; end
ActiveAdmin.register PoliticalDiscussion do; end

Hope it helps.
