ActiveAdmin: how to leave user password unchanged?

Question

I am using ActiveAdmin as my administration backend in my rails app. Basically, I have an admin_user and a user model.

When I create a new us

You can validate the password only on create because bcrypt when updating will still validate password presence.

class User
   validate :password, :password_confirmation, presence: true, on: :create 
end

In my opinion this is much simpler while causing no risk, and allows you to use a single partial form for create and update routes with an if statement showing/not showing password input field like so:

<%= form_for(user, url: users_path) do |form| %>
<%= form.label 'Name' %>

<%= form.text_field :name%>


<%= form.label 'email' %>

<%= form.text_field :email%>


<%= form.label 'Password' %>

<%= form.password_field :password%>


**<% if form.object.new_record? %>**
    <%= form.label 'password_confirmation' %>

    <%= form.password_field :password_confirmation%>

**<% end %>**

<%= form.submit (form.object.new_record? ? 'create' : 'update')  %>
