Hi,  
I am trying to generate a link to delete a relationship, so I’ve done  
the code bellow. THis is the full code, the part for deleting the  
relationship is at the bottom of the code. I am using a restful  
controller

\<% unless item.user\_participe?(current\_user) %\>  
\<%form\_for Participant.new do |f| %\>  
\<%= f.hidden\_field :defi\_id, :value =\> item.id%\>  
\<%= f.submit “Participer!”, :disabled =\> !current\_user %\> \<%=  
link\_to(“Créez un compte pour participer”, register\_path) unless  
current\_user %\>  
\<% end %\>

\<%else%\>  
_Vous participez à ce défi_  
\<%= link\_to “Ne plus participer”,  
participant\_path(item.participants.find\_by\_user\_id(current\_user.id)) ,  
:method =\> :delete, :confirm =\> “Etes vous sur de ne plus vouloir  
participer?” %\>  
\<%end%\>

This is the error message:  
participant\_url failed to generate from {:action=\>“show”,  
:controller=\>“participants”, :id=\>#\<Participant user\_id: 1, defi\_id: 1,  
is\_valide: “false”, fin\_defi: “2010-04-24 00:00:00”, created\_at:  
“2010-04-25 15:15:35”, updated\_at: “2010-04-25 15:15:35”\>}, expected:  
{:action=\>“show”, :controller=\>“participants”}, diff:  
{:id=\>#\<Participant user\_id: 1, defi\_id: 1, is\_valide: “false”,  
fin\_defi: “2010-04-24 00:00:00”, created\_at: “2010-04-25 15:15:35”,  
updated\_at: “2010-04-25 15:15:35”\>}

The reason it is failing is because it is performing a GET request.

Wrap the “delete relationship” in a form( with :method =\> :delete) and  
it should work
