How to Encrypt data after validation in Ruby on Rails?

I am using devise for authentication, register. Now i want to save emailId in MySQL in encrypted format. So i use gem 'aescrypt'.

My controller:

 def create
    @dashboard_user = DashboardUser.new(dashboard_user_params)
    @dashboard_user.created_by=current_dashboard_user.username
    @dashboard_user.company_id=current_dashboard_user.company_id
    active_ind = ""
    email = @dashboard_user.email

    if params["active"] == nil then
      active_ind = "0"
    else
      active_ind = "1"
    end

    @dashboard_user.active = active_ind
    @dashboard_user.email= AESCrypt.encrypt(email, "password")

    respond_to do |format|
      if @dashboard_user.save
        format.html { flash[:notice] = 'User successfully Created.' and redirect_to action: "index"}
      else
        @dashboard_user.email = email
        format.html { render :new }
      end
    end
  end

When i try to save user, it throws Email invalid. I removed validation for email in model. Even though same error exists. What problem it is? If there any way to encrypt data after validation?

Thanks in advance.

On its model you can just declare like the example scenario below: E.g.:

after_validation :encrypt_cc_number, on: :create

It will validate then encrypt the credit car number on a create action.

You can encrypt the data using using a method triggered by the after_validation callback. It is described here: http://api.rubyonrails.org/classes/ActiveRecord/Callbacks.html

How do you validate email? You could use a custom method to decrypt it before validate against (for e.g.) a regex. Alternatively, you can use ActiveRecord Callbacks. In your case, after_validation can be useful :)

after_validation(on: :create) do
  self.email= AESCrypt.encrypt(email, "password")
end
