In Rails 3.1, count is ignoring the include specified in my default_scope in BudgetAccount -

class Budget
  has_many :accounts, :class_name => 'BudgetAccount', :as => :poly, :dependent => :destroy
end

class BudgetAccount
  belongs_to :account
  belongs_to :poly, :polymorphic => true
  default_scope where('accounts.inactive = ?', false).order('accounts.number').includes(:account)
end  

class Account
end


Rails 3.0 works as expected -

count = Budget.first.accounts.where('total > 100000').count

SELECT COUNT(DISTINCT "budget_accounts"."id") FROM "budget_accounts" LEFT OUTER JOIN "accounts" ON 
"accounts"."id" = "budget_accounts"."account_id" WHERE (accounts.inactive = 'f') AND 
("budget_accounts".poly_id = 1 AND "budget_accounts".poly_type = 'Budget') AND (total > 100000)



Rails 3.1 breaks -

count = Budget.first.accounts.where('total > 100000').count

SELECT COUNT(*) FROM "budget_accounts" WHERE "budget_accounts"."poly_id" = 1 AND "budget_accounts"."poly_type" = 'Budget' AND 
(accounts.inactive = 'f') AND (total > 100000)
