Hi Jeremy,
Thanks for your reply.

While submitting still r['album'] returns nil. But r.params returned the
following:

{"forme_demo/album"=>{"name"=>"Ethnicity", "release_date"=>"2013/03/01",
"copies_sold"=>"31000", "debut_album"=>"f", "out_of_print"=>"t",
"artist_attributes"=>{"name"=>"Yanni"},
"tracks_attributes"=>{"0"=>{"number"=>"1", "name"=>"Rite of Passage",
"length"=>"19"}, "1"=>{"number"=>"2", "name"=>"For All Seasons",
"length"=>"28"}, "2"=>{"number"=>"3", "name"=>"The Promise",
"length"=>"21"}}}}

r.post 'album' do
logger.info p r.params
logger.info p r['album']
r.redirect r.referrer
end

I have not edited much in others, but posted for your reference.

r.is 'grid' do
@page_title = 'Single Level Grid'
@subform_opts = {:grid=>true}
@Album = Album.new
demo :album_nested
end

album_nested.erb

<% form(@Album, form_attr, form_opts) do |f| %>


<% f.inputs([:name, :release_date, :copies_sold, :debut_album,
:out_of_print], :legend=>:Album) do %>
<%@album.associations[:artist] = Artist.new%>
<%@album.associations[:tracks] = [Track.new, Track.new, Track.new]%>
<%= f.subform(:artist, {:inputs=>[:name]}.merge(subform_opts)) %>
<% f.subform(:tracks, {:inputs=>[:number, :name,
:length]}.merge(subform_opts)) do %>
<%= f.tag(:td, {}, ['Delete'])%>
<%end%>
<% end %>
<%= f.button(:value=>'Submit') %>
<% end %>

Please let me know, if you still need more information.

Thanks.

Hi Jeremy,
Wow, its working. Thank you very much for your valuable time.

This small issue, drilled me to go through your documentation completely.

I am so inspired by your SPAM demo accounts entry. I would like to apply
the same in our application by having a partial to enter the data. By
clicking the Add button, we can initialize Track object and on subsequent
add, we can push new Track objects in the subform.

We can have button to delete an entry in the subform.

Please let me know, if I am anywhere wrong.

Thank you once again, for your continuous support.

Best regards,

I.Murugesan

Looks like you want to use r['forme_demo/album']. This is probably
because the model is namespaced in the demo site. You can override the
forme_namespace method for the model to return "album", then r['album']
will work.

Thanks,
Jeremy
