How to change the confirmable to be optional in devise?

I have devise for authentication and I have confirmable in devise for User model.

I want this to be optional based on the data I send.
That is there is a type field in User model.
If I send value 1 for type then the confirmable should be present.
if value is 2 then there should not be confirmable and the account should be activated automatically.

How can I do this? Please help!!

Solution

I think you can use skip_confirmation! method here. So it will not fire confirmation mail for user and will be confirmed.

before_save :require_confirmation, :on => :create

def require_confirmation
   self.skip_confirmation! if field == "value_2"
end
