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?
