Rails - Mar 2009 - How to delete a record inside of an association

I''m a noob having a hard time, and it''s probably really
simple.

Here''s the way it''s set up:
Client has many Bins
Bin belongs to Client
In my Client show view I have it render a partial that lists all the
records in Bin associated with Client.

I need to have a destroy link for each of the Bin records. Right now I
have it configured in my Bin partial as:
<%= link_to("Delete", { :action => "destroy", :id
=> @bin }, :confirm
=> "Are you sure?", :method => :delete) %>

This just throws back an error saying that there is not a Client with
that id.

I can''t figure out how to tell it to delete the bin not the client
with that id.

Any helpful suggestions? Cheers.

I guess it''s because, that when you''re rendering partials
you''ll not
be given an instance variable, but a local variable. You can try to
see if this is enough to fix the problem:

<%= link_to("Delete", { :action => "destroy", :id
=>
bin.id }, :confirm
=> "Are you sure?", :method => :delete) %>

I simply removed the @ to reference a local variable instead. (And I
call the #id method on the Bin, but that''s optional.)

No. The problem is the current controller is the client controller,
so :action => destroy routes you to /clients/destroy, which
unsurprisingly destroys clients not bins. If you''re feeling old school
you would add :controller => ''bins'' to your hash, but a
more modern
way to do this would be

link_to ''Delete'', bin_path(@bin), :method => :delete
