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| %> <label><%= friends.object.name <http://friend.name> %></label> <%= friends.text_field :relationship_to_you %> <% end %> <p><%= f.submit "Submit" %></p> <% end %> On 12 April 2010 22:31, toamitkumar-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org <toamitkumar-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> Yes u can with > friend.object.name > > On Apr 11, 10:13 pm, John Grimes <m...-vOAwBkqxSF3QKcMg3i/TZg@public.gmane.org> wrote: > > 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. > > > > John Grimes > > -- > You received this message because you are subscribed to the Google Groups > "Ruby on Rails: Talk" group. > To post to this group, send email to rubyonrails-talk-/JYPxA39Uh5TLH3MbocFF+G/Ez6ZCGd0@public.gmane.org > To unsubscribe from this group, send email to > rubyonrails-talk+unsubscribe-/JYPxA39Uh5TLH3MbocFFw@public.gmane.org<rubyonrails-talk%2Bunsubscribe-/JYPxA39Uh5TLH3MbocFFw@public.gmane.org> > . > For more options, visit this group at > http://groups.google.com/group/rubyonrails-talk?hl=en. > >-- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
