# Customizing the Form Active Admin gives complete control over the output of the form by creating a thin DSL on top of the fabulous DSL created by Formtastic (http://github.com/justinfrench/formtastic). ActiveAdmin.register Post do form do |f| f.inputs "Details" do f.input :title f.input :published_at, :label => "Publish Post At" f.input :category end f.inputs "Content" do f.input :body end f.buttons end end Please view the documentation for Formtastic to see all the wonderful things you can do: http://github.com/justinfrench/formtastic If you require a more custom form than can be provided through the DSL, you can pass a partial in to render the form yourself. For example: ActiveAdmin.register Post do form :partial => "form" end Then implement app/views/admin/posts/_form.html.erb: <%= semantic_form_for [:admin, @post] do |f| %> <%= f.inputs :title, :body %> <%= f.buttons :commit %> <% end %>
