Including a form from a separate file with Ruby on Rails -

i have form create new player in /players/new.html.erb

<%= form_for(@player) |f| %> ... <% end %> 

which want include in home page.

if copy-paste whole form error: undefined methodmodel_name' nilclass:class`

i can include form in iframe

<div> <iframe src=../players/new.html> </div> 

but shows whole page headers , footers.

how can include form, ideally directly file (i.e. no copy-paste)?

your form_for requires @ least @player present

if want include form on home page in home controller action initialize new player instance:

@player = player.new 

but must aware views of playercontroller (or whatever controller have form created for) can rely on having access helper methods playerhelper might need include in homehelper
