Add roles after importing users

[sharathm]

Hi,
I have a standard Devise User model, for which I want to provide a bulk upload feature.
I also have rolify integrated and so as people register on the site, I give options for them to either register as a student or a teacher.
What I want to do, is use active_admin_import to provide a bulk upload feature for teachers only. So basically after the import is done, i need to assign them to teacher role.
In a normal scenario, this is done by new_user.add_role(:teacher), assuming new_user is a newly created user object.
I am not able to figure out how to get access to the instance of the created object after insertion so that I can accomplish the same.

ActiveAdmin.register User do

active_admin_import validate:false,
after_batch_import: proc { |import|

**<not sure what to put here>**

},
before_batch_import: proc { |import|
	import.csv_lines.length.times do |i|
		import.csv_lines[i][2] = User.new(password: import.csv_lines[i][2]).encrypted_password
	end
},
template_object: ActiveAdminImport::Model.new(
	hint: "file will be imported with such header format: 'full_name',''email','password'. They will assigned as teachers"
),
timestamps: true,
batch_size: 1000

index do
    selectable_column
    column :full_name
    column :email
	column :phone_number
	column :roles do |user|
		user.roles.collect {|c| c.name.capitalize }.to_sentence
	end
	column :current_sign_in_at
	column :last_sign_in_at
	column :created_at

  end
end

Is my use of after_batch_import correct or should I go for after_import and in each case, how do i get access to the instance of the newly imported object or the array of objects imported so that I can assign the role.

Any help is appreciated

Thank you
