Edit form has wrong selected value after encrypted value

I have private method on controller

private

def set_address
   @address = Address.find(params[:id])
end

def city_options
    @city_options = []
    if @address
      @city_options = City.where(province_id: @address.province_id).collect{ |x| [x.name, x.id] }
    end
  end

And on views of _form.html.erb

<%= f.select :city_id, @city_options, { :prompt => I18n.t('prompt.select_city') }, class: 'select-city text address-city' %>

It's fine on new form and edit has right selected value, but when I encrypt the id in city_options method

@city_options = City.where(province_id: @address.province_id).collect{ |x| [x.name, encrypted_id(x.id)] }

List of city is shown and value of id is encrypted but wrong selected a value of city, just selected id on top of list.

Wrong value is selected because the saved city_id do not match the encrypted_id of any select list option.

To get over it you can use options_for_select method. Try following if encrypted_id method is a helper method

<%= f.select :city_id, options_for_select(@city_options, selected: encrypted_id(f.object.city_id)), { :prompt => I18n.t('prompt.select_city') }, class: 'select-city text address-city' %>

Check this link http://apidock.com/rails/v3.1.0/ActionView/Helpers/FormOptionsHelper/options_for_select

If encrypted_id method is a controller method, you have pass currently selected value by encrypting it from controller. Or you can use helper_method :encrypted_id in controller to make encrypted_id method available in view and can use above mentioned method
