Activeadmin form - Rails

Question

How I can make this form in activeadmin?

<%= form_for(@album, :html => {:multipart => true}) do |f| %>
.....

<div class="field">
<%= f.label :apellido %><br />
<%= f.text_field :apellido %>
</div>

<div class="field">
    <p>Hijos</p>
    <%= f.fields_for :hijos do |builder| %><br /><br />
    <%= builder.label :nombre, 'Nombre Hijo' %><br />
    <%= builder.text_field :nombre %><br />
    <%= builder.label :apodo, 'Apodo Hijo' %><br />
    <%= builder.text_field :apodo %><br />
    <%= builder.label :hijo_id, 'favorito' %>
    **<%= f.radio_button :hijo_id, builder.object.id %>**
    <% end %>
</div>

I need put the option of hijo_id inside the for of :hijos

Try with :

 f.input :avatar_item_id, :as => :boolean, :value =>  app_f.object.id

But not work.

Thanks

What are the relationships you have set up for Album and Hijo models? — Steph Rose

This should work once you register the Album model as an ActiveAdmin resource:

  form :html => {:multipart => true} do |f|
    f.inputs "Principal" do
      f.input :apellido
    end

    f.inputs "Hijos" do
      f.has_many :hijos do |h|
        h.input :nombre
        h.input :apodo
        h.input :favorito, :as => :check_box
      end
    end
    f.buttons
    end

If you want to mark a child as a favorite, you need a boolean favorito field in the hijos table, not a hijo_id field.

I want that father table save the favorites son (hijo) if father table has the favorites just need a query. If son table save the favorites need other query for know who is the favorites and need made more validations for not save duplicates favorites in sons tables Greetings

In that case the hijo_id must be outside the nested form, not inside. The hijo_id must be saved in the Father table

Hubermann Over a year ago

the 'favorite' field is part of the Fhater model but need collect the value of the Item Need something like this. (in front form works, but not in the admin) f.input :favorito, :value => h.object.id
