Ruby on Rails

Hi guys,

I've been coding in rails for a while now but I've never been able to render fields_for as a partial. I don't know if this is possible, as it should be dead simple. Normally when I run across this problem, I just find another way to do it.....but sadly, it's time to pay the piper....any help would be greatly appreciated.

My code looks like so:

#form.html.haml

=render partial: "html_panel_fields", locals:{f: f}

 

and my partial looks like this 

 

#_ html_panel_fields.html.haml

= f.simple_fields_for :html_panels do |o|

my error is as follows:

undefined local variable or method `f' for #<#<Class:0x007fdf7077c8e0>:0x007fdf72175738>

It looks like I have two classes embedded here......what gives?

Thanks!
