Hi all,
I apologize for the funky subject of this post.
I have a partial I created while recreating a railscasts example (nested
resources part 2 -
http://railscasts.com/episodes/197-nested-model-form-part-2) and I''ve
come to a halt.
What I want to do is force a question to be asked if this is a new
"survey". Basically I want to build one question in the new action and
display it in the form and remove the link_to_remove_fields helper - BUT
I also want to be able to add AND remove new questions. While making
sure that the inital question cannot be removed.
Hopefully this makes sense. Below is my partial code:
[code]
<div class="fields">
<%= f.error_messages %>
<p>
<%= f.text_field :content %>
<% unless f.object.new_record? %>
<%= link_to_remove_fields "remove", f %>
<% end %>
</p>
</div>
[/code]
I added <% unless f.object.new_record? %> to omit the remove link on the
new action and this works. However when someone clicks the ''add
question'' (code not shown but identical to the railscast code) it
display the fields but obviously also omits the remove link for the
newly added questions.
How can I omit the first remove link but show the remove link for newly
added questions in the new action? Please let me know if you need more
info!
Thank you!
-Tony

Hi Tony, Hope ur using Jquery Add the class to the remove link and add the following line of code> <div class="fields"> > <%= f.error_messages %> > > <p> > <%= f.text_field :content %> > > <% unless f.object.new_record? %> > <%= link_to_remove_fields "remove", f,:class=>"remove" %> > <% end %> > </p> > </div>$(document).ready(function(){ $(".remove").eq(0).remove() }) Tony Tony wrote:> Hi all, > > I apologize for the funky subject of this post. > > I have a partial I created while recreating a railscasts example (nested > resources part 2 - > http://railscasts.com/episodes/197-nested-model-form-part-2) and I''ve > come to a halt. > > What I want to do is force a question to be asked if this is a new > "survey".

Using jquery now! Is there really that big of a difference? I know everybody raves about it - more lightweight is all? For others to learn here''s what I did. 1. I put babu''s script in the bottom of the form (eventually I''ll put it in the head via a yield). 2. Put the link_to_remove_fields in a span with class remove (<span class="remove"><%= link_to_remove_fields "remove", f %></span>) That''s it! Hope this helps someone else out there. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
