Nested forms: Can you access the object from within fields_for?

Hi all,

Say I had the following form:

<% form_for @user do |f| %>   <%= f.error_messages %>   <% f.fields_for :friends do |friends| %>     <%= friends.text_field :relationship_to_you %>   <% end %>   <p><%= f.submit "Submit" %></p> <% end %>

Is it possible to access the current object within that fields_for block as it iterates through?

For example, could I add another line that looked something like this with the friend's name:

<% form_for @user do |f| %>   <%= f.error_messages %>   <% f.fields_for :friends do |friends| %>     <label><%= friend.name %></label>     <%= friends.text_field :relationship_to_you %>   <% end %>   <p><%= f.submit "Submit" %></p> <% end %>

Thanks for your help.

That works perfectly, thanks!

Just to clarify for anyone else reading this, code such as this should work:

<% form_for @user do |f| %>

<%= f.error_messages %> <% f.fields_for :friends do |friends| %> <%= friends.object.name %>

<%= friends.text_field :relationship_to_you %> <% end %>

<%= f.submit "Submit" %>

<% end %>
