Re: [Rails] local variables in _form.html.erb undefined

[Walter Lee Davis]

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?
