Hi,
I got News model that has_one Asset. Asset belongs_to News.
AssetsController has only detroy method, asset is created in
NewsController create action. Both resources are in admin namespace.
Now I''d like to delete the asset. I tried something like this:
<%= link_to ''delete'', admin_news_item_asset_path(@news,
@news.asset), :confirm => ''Are you sure?'', :method =>
:delete %>
but I get the following error:
undefined method `has_key?'' for #<Asset:0xb6a22798>
vendor/rails/activerecord/lib/active_record/attribute_methods.rb:
240:in `method_missing''
vendor/rails/activerecord/lib/active_record/associations/
association_proxy.rb:128:in `send''
vendor/rails/activerecord/lib/active_record/associations/
association_proxy.rb:128:in `method_missing''
(eval):3:in `admin_news_item_asset_path''
...
If I use the following link:
<%= link_to ''delete'', admin_news_item_asset_path(@news),
:confirm =>
''Are you sure?'', :method => :delete %>
I don''t get any errors, but I don''t get asset id as well, only
news_item_id. I could use this to delete associated asset, but I''d
like to make it work as it should.
The routes are as follows:
map.namespace :admin do |admin|
admin.resources :news, :singular => ''news_item'', :member
=>
{ :preview => :get } do |news_item|
news_item.resource :asset
end
end
I''m using rails 2.0.2.
Thanks in advance

not 100% sure, but: admin_news_item_asset_path(@news, @news.asset) should be something like: admin_news_item_asset_path(@news, :asset_id => @news.asset) since rails can guess the param name (:id) only for those parts of the path, that are declared in the routes, all others must be named in hash fashion -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

but i''m not sure, if you need that here. why hand over the asset.id, if it''s stored in @news anyway you could simply call the thing for @news and in destroy use @news.asset or in the has_one declaration simply add: has_one :asset, :dependent => destroy and you''ll never have to think about it again... -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

It works, but I still think that rails should automatically figure out ID of the second parameter passed. If I run "rake routes", I can see "admin_news_item_asset_path" listed there together with DELETE method... The generated url is "/admin/news/ 23/asset?id=35", but it should be enough for rails to figure out ID of the asset even with url like this "/admin/news/23/asset". --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Otherwise, Rails can''t figure out which of N assets you want to delete. Sorry my poor English.
