Show the code where you are trying to render this form. A partial that renders implicitly (like in a scaffolded CRUD form):
#/app/views/posts/new.html.erb
<%= render 'form' %>
...will get a local variable named `post` in the render context.
What does your controller look like, and what does the enclosing template look like that is rendering this partial?
