How to check validation on creation method if its called from specific route?

问题

I want to validate column presence on creation method if the creation method is called from some other route. For example, If I have following two routes:

post 'create_item', to: 'item#create'
post 'create_verified_item', to: 'item#create_verified'

I need to define in Item model something like this:

validates :verified_number, presence: true, if: Item.action_name == "create_verified"

Anyone can help?

回答1:

Ideally you can add a attribute to item to check that, something like:

# model
class Item
  attr_accessible :action_name

  validates :verified_number, presence: true, if: :create_verified?

  def create_verified?
    action_name == 'create_verified'
  end
end

# controller
item = Item.new(item_params)
item.action_name = params[:action]
item.save
