How to validate attr_accessor ruby

In my model i have :code attr_accessor

<%= text_field_tag :code, "", class: 'form-control text optional', placeholder: 'Code' %>

When the form is submitted, i get from params the :code, and i want so validate some errors

controller

@tourney_subscribe = TourneySubscribe.new(params.tourney_subscribe)

validate_code(params[:code]) if params[:code].present?
#now it adds the error

# when .valid? it clean the error
if @tourney_subscribe.valid?
...
else
   render :next
end

but in my controller i'm using .valid? and it clean the errors and then don't show the :code error

In this case how to treat errors with an attr_accessor?

You can validate virtual attribute as usual model attribute, for example

class MyModel < ApplicationRecord
  attr_accessor :code

  validates :code, presence: true
end

And other validations too
