Still trying to figure this out.
Playing around with fields_for and child_index, it seems i'm missing an
accepts_nested_attributes_for :volumes
somehow.
But where is the correct place to put this?

I'm working on my own compute_resource but I got stuck creating more
than one volume.
To drag down the problem i looked into the foreman code.
In app/helpers/layout_helper.rb is the function new_child_fields_template
here i added a f.hidden_field
content_tag(:div, :class => "#{association}_fields_template
form_template", :style => "display: none;") do
form_builder.fields_for(association, options[:object],
:child_index => "new_#{association}") do |f|
f.hidden_field(:_destroy, :class => :destroyFlag, :value => 0)
#render(:partial => options[:partial], :layout =>
options[:layout],
# :locals => { options[:form_builder_local] => f
}.merge(options[:form_builder_attrs]))
end
end
the generated html code looks like this:
<div class="volumes_fields_template form_template" style="display:
none;">
<input id="host_compute_attributes_volumes__destroy"
class="destroyFlag" type="hidden"
name="host[compute_attributes][volumes][_destroy]" value="0">
</div>
but i think it should look like this:
<div class="volumes_fields_template form_template" style="display:
none;">
<input id="host_compute_attributes_new_volumes__destroy"
class="destroyFlag" type="hidden"
name="host[compute_attributes][new_volumes][_destroy]" value="0">
</div>
so the :child_index => "new_#{association}" is ignored?
same code is working well with interfaces:
<div class="interfaces_fields_template form_template" style="display:
none;">
<input id="host_interfaces_attributes_new_interfaces__destroy"
class="destroyFlag" type="hidden"
name="host[interfaces_attributes][new_interfaces][_destroy]" value="0">
</div>
any ideas how to solve this?
