How to Encrypt data after validation in Ruby on Rails?

Question

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.

Can you post a snippet of your DashboardUser class? What's the auth key in config/initializers/devise.rb ? — Novae

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

undefined method `after_validation' for DashboardUsersController:Class

Where i want to define?

Oh no, is an Active::Record method! You should put it in your model, not in the controller :)! Put it in DashboardUser

How to decrypt in view?

You're welcome :). Keep in mind that next time you'll get the record from the database, the password will be already encrypted. So the validation could fail. You should validate it only during creation, just add on: :create as a parameter to the validates :email (that you can now re-enable

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

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.
