User has_many Goals, only want the new goal to show on edit screen

[Bob Larrick]

 <%= f.simple_fields_for :goals do |goal| %>

...

<% end %>

Shows inputs for all goals, both the existing ones and the new one set up in the controller with  @user.goals.build.

How can I only show inputs for the new one, and not the existing ones?

You should be able to pass in the object you want instead. Please take a look at the fields_for documentation in Rails, Simple Form pretty much delegates to it: http://api.rubyonrails.org/classes/ActionView/Helpers/FormBuilder.html#method-i-fields_for

Hope that helps.

Thanks!

I ended up doing something like

<% if goal.object.new_record? %>

and that seems to be working well.

Yeah, it will, although it'll be possibly slower if you have many associated objects, because it'll process all records just to render a single one. But again as you said, it works, so whether it's good enough or not is up to the context it's in :)
