Rails Active Admin Scope with Params

Question

Using active admin with ActiveRecord scopes was explained here: Rails3 Active Admin: How to display only Open status records when first click on Shipments tag?

Now I'm trying to do it for a scope with params .

In my model i have:

#app/models/shipments.rb
scope :by_status, -> (status) { where(status: status) }

I want to be able to use this in app/admin/shipments.rb to be something like

# app/admin/shipments.rb
scope :by_status 'open'

Is there an active admin way to do that?

Answer 1

You can use a block:

  scope :open do |shipments|
    shipments.by_status('open')
  end

If you want this to be the default scope:

  scope :open, default: true do |shipments|
    shipments.by_status('open')
  end
