Question

我试图在def create方法中传递以下内容。 create方法位于事务控制器中。

@purchases = current_shop.purchases.build(purchase_params)
@purchases.save!

private

def purchase_params
  params.require(:purchase).permit(:shop_id, :subscription_id, :created_at)
end

并返回此错误：

ActionController::ParameterMissing in TransactionsController#create
param is missing or the value is empty: purchase
