You should be able to do this via the form DSL method provided by ActiveAdmin. More details are in the documentation for ActiveAdmin and Formtastic.

Unfortunately, I don't believe ActiveAdmin nicely lets you have a completely different form rendered for new and edit. Using the partial rendering method in the documentation though you could conditionally change the form in the view based on @object.persisted?.

# app/admin/post.rb
ActiveAdmin.register Post do
  form :partial => "form"
end

# app/views/admin/post/_form.html.erb
<%= semantic_form_for [:admin, @post] do |f| %>
  <% if @post.persisted? %>
    Edit Form (Maybe rendered via a partial)
    <%= f.inputs :title, :body %>
    <%= f.buttons :commit %>
  <% else %>
    New Form
  <% end %>
<% end %>

Getting a forbidden attributes error when editing. Do you know why? — BenMorganIO, May 01 '14 at 22:01
@BenMorganIO, Probabily you need to whitelist those params on your controller. Something like: `def model_params params.require(:model).permit(:attribute) end` — luizrogeriocn, Apr 11 '16 at 20:08

You can render any view your like if you provide its full path to the render method. Something like that:

# app/admin/post.rb 
ActiveAdmin.register Post do  
    controller do
        def edit 
            render 'admin/posts/myEditTemplate', :layout =>"active_admin"
        end
        def new
            render 'admin/posts/myNewTemplate', :layout =>"active_admin"
        end
    end
end 

# app/views/admin/posts/myEditTemplate.html.erb
    # Your erb view for edit here
# app/views/admin/posts/myNewTemplate.html.erb
    # Your erb view for new here

I wanted two forms on the screen. For partials. This works great.. thanks. — baash05, Jun 25 '19 at 02:08
