Rails - Oct 2006 - DHH presentation: how to actually create the membership

I have followed tutorials and the dhh presentaion for creating my 
application but i get a bit stuck on creating and deleting the 
relationships between items.
eg
user - memberships - groups


page 21 of the dhh presentation has this, though im not sure how to 
create this post from a link_to?

#POST /memberships?group_id=1&user_id=2

with this delete action it appears that the membership id is already 
known
#DELETE /memberships/3

would be great to see an example of this

In general it can be achieved using: link_to(''Foo'',
{:controller =>
''memberships'', :group_id => 1, :user_id => 2}, :method
=> ''post'')

I believe there''s some shortcut when using the REST stuff, but I  
can''t recall how it''d look now.

thanks for the reply.

That partly worked.


127.0.0.1 - - [04/Oct/2006:21:01:02 New Zealand Standard Time] "POST 
/memberships?user_id=1 HTTP/1.1" 302 117
http://localhost:3000/categories/1/products/2/parts -> 
/memberships?user_id=1


i am having to pass the group_id through session. As it is trimmed from 
the url, see the console output above. Checking this further i added a 
''puts'' line to show the values of the user_id and group_id:

 puts params[:group_id] >> nil
 puts params[:user_id] >> 1


The shortcut version your refering to is the named route 
new_membership_path. I get an error when using this.
